How to treat bedbugs with cold fog

• By Vil Malinoshevsky
• Destruction of bedbugs

Today, treating a room with cold fog is one of the most common and effective methods of killing bedbugs. Disinfestation specialists carry out disinfestation using this particular technique, sometimes combining it with hot fog and other techniques.

Practice shows that cold fog provides the optimal combination of cost and efficiency of room treatment, as well as time consuming and safety for residents. Depending on the level of infestation of the apartment and house, using this technique you can remove bedbugs in just 1-2 hours.

What is cold fog

Cold fog is a method of killing bed bugs by spraying a liquid solution through a special steam generator. The advantage of the procedure is the ability of chemicals to remain suspended in the air for a long time and penetrate into small crevices on all surfaces and interior items.

A room treatment technology based on the use of liquids that contain toxic substances is cold fog disinfection. Such products are sprayed using a fog generator - this is special equipment that supplies the substance under pressure to the sprayer. As a result, a fine suspension is released.

The insecticide seeps into furniture niches, the space above stretch ceilings and under wallpaper, into small uneven floors and other insect habitats. But you won’t be able to do this with a stream of regular aerosol.

The particles are so small that they do not immediately settle on the surface. Their size varies from 10 to 50 microns. These particles are formed when water molecules are broken up as they pass through the nozzle and sprayer under pressure. Moreover, they fly out at high speed. Due to this, the particles spread through the air and can settle at a significant distance from the fog generator.

For comparison, analogues in the form of an aerosol and spray act in a similar way, but the insecticide settles on the surface almost immediately after spraying. This difference in processing technologies allows you to obtain different results.

It is called cold fog because when spraying a substance at room temperature is used. This technology should not be confused with hot fog. In this case, different equipment is used, and the processing result is different.

The mist allows you to distribute the insecticidal agent in a fine layer over 99.7% of the treated surface

Dry and liquid fog

Dry bed bug mist is the most advanced technology available. Baiting bedbugs using dry insecticidal fog is especially appropriate in apartments heavily crowded with furniture. The treatment procedure in this way allows you to get rid of parasites in one session.

Dry mist against bedbugs fills the entire area of ​​the room, and the remaining insecticide particles scattered throughout the room serve as a reliable barrier protection against the penetration of insects from neighboring rooms.

Various liquid insecticide options can be used using cold and hot generators. Treatment of a room with a hot or cold cloud is performed only by specialists.

Units for manipulating cold or hot insecticides are expensive, so purchasing them for home use is not possible, and there is no point in doing so.

Pros and cons of the method

This approach to pest control is appreciated by professionals and potential clients, as evidenced by numerous positive reviews. Advantages of cold sanitation of an apartment:

• Effectiveness - the extermination of bedbugs occurs at a time, since under the influence of cold temperatures the parasitic colonies die instantly.
• Safety for others - if personal safety precautions are followed, the equipment is not dangerous for people and pets.
• The possibility of using liquid insecticidal solutions is possible with an aerosol type of steam generator.
• Prolonged action - a harmful cloud of fog hovers in the air for up to 5 hours, then the particles warm up and fall in an even layer on the surface. In this case, even the ceiling is captured.
• Large-scale capture areas - the sprayed product penetrates into cracks and other nooks and crannies that cannot be reached manually.
• Extended protective spectrum - a detrimental effect is exerted not only on bloodsuckers, but also on other types of insects living in the house.
• Cost-effectiveness – low consumption of the drug, which reduces financial costs.
• No trace of processing - after applying the product in this way, there are no stains or streaks left afterwards.

When working with cold fog, the fact of increased environmental humidity is taken into account. Therefore, items that deteriorate from excessive humidity must first be removed from the room.

Application of the method

An important role in any disinfestation is played by the correctly selected product to be used as an insecticide. And here a significant role is played by such factors as safety for humans, the persistence of the smell (after all, we don’t want to smell the drug for months), the price of the insecticide and how effective it is. Pest control services use many drugs: Tetrix, Xulate, Sinuzan and many others. They all have their pros and cons. There are less smelly products such as: Delta-Zone, Get, Lambda-Zone, etc.

Treatment with a hot fog generator is almost the same, the difference being that the solution is supplied hot and the particle sizes are even smaller, 5 - 30 microns. The settling of such fog takes up to 10 hours, and cannot be used everywhere. If we compare the effectiveness of these two methods, then in the end result the difference will be on the side of hot processing by a slight margin. So, for example, if we take the processing efficiency as 1, then the result will be 0.7: 1.1 in favor of hot processing. But everywhere there are nuances, such as the price of treatments, the number of infections in an object, and the overall possibility of treatment. Hot treatment has a higher price if the facility is not neglected and the number of bedbugs is small; cold treatment is sufficient. Another factor is the time you have; hot processing is a rather lengthy undertaking.

Preparing the apartment for processing

Before starting disinfestation, prepare the living space accordingly:

How to independently detect bedbugs in an apartment?

• They remove strangers and pets. If there is an aquarium, turn off the air exchange system and cover it with glass.
• Clothes and bedding are packed in tightly closed bags. The same applies to food and kitchen accessories.
• Furniture is moved away from the walls to free up access to the baseboards.
• Paintings and other interior attributes are removed from the walls so that steam can be walked on the reverse side.
• The sofas are folded out, the doors of cabinets and cabinets are opened slightly.
• Ventilation outlets, windows and doors are tightly covered.
• They do wet cleaning, wipe off dust from surfaces, including baseboards.

There is no need to take flowers out of the house, cold treatment will have a beneficial effect on them - it will prevent the appearance of pests: mites, aphids, scale insects, whiteflies. In apartment buildings, neighbors should be notified about the upcoming pest control.

It is advisable that they temporarily block the ventilation duct. When the room is prepared, wet cleaning is performed - the absence of dust will improve the effect of the toxic chemicals. Active components will not be retained by dirt particles.

The apartment should be prepared before processing by packing all things in boxes, containers, bags

What it is?

Bedbugs usually live in secluded, hard-to-reach areas of apartments. Treating your home with classical means does not always lead to a positive result. Sprayers and atomizers do not provide full coverage of the insect's habitat. Some pests die, and some individuals hide under the wallpaper, in crevices where poison particles do not enter.

According to reviews, cold fog for bedbugs is an effective method. With it, the room is filled with small drops of insecticides. To supply the active substance, special devices are used - generators. The temperature of the sprayed cloud is the same as in the apartment, which is why the technology is called “cold”.

Droplets of insecticidal fog during the operation of the generator are 10-80 microns. The air flow provided by the device distributes the working solution over 30-10 m in seconds. The indicators are determined by the class of the generator.

In addition to cold fog for bedbugs, there is a hot method. The methods differ in the type of generator used:

How cold fog works

Cold fog generators are produced both professional and small household. Prices for a household generator start at an average of 20 tr. and if frequent processing is necessary (private hotel, recreation center, etc.) they will pay for themselves. The cold fog generator differs from a conventional spray gun in its high efficiency.

Bedbugs often hide in small crevices in the floor and walls, in niches of furniture, in suspended ceilings and other hiding places that a person may not even be aware of. A special device ensures penetration of the insecticide into hard-to-reach places, which cannot be done manually.

The processing is as follows:

• When the generator is turned on, it releases jets of gas containing tiny particles of a substance harmful to bedbugs. Vapors of the drug spread throughout all corners of the apartment, penetrating into cracks and holes where insects like to hide.
• The insecticide gradually settles on all horizontal surfaces, as well as on the bodies of insects. Bedbugs inhale a certain amount of the drug, which causes damage to the nervous system, paralysis and death of the parasites. If the bugs have not inhaled a sufficient amount of poison, it enters their body through the chitinous covers while moving on treated surfaces and the insects die a little later.
• As a rule, the effect of the product lasts several weeks. This makes it possible to destroy individuals that hatched from eggs that the bugs managed to lay before dying.

Cold fog is intended for treating residential premises, as well as public institutions occupying a small area. If it is necessary to poison bedbugs on an industrial scale, in the area adjacent to a building or in a warehouse, this method will be ineffective.

Preparing the premises

Before processing, we prepare the apartment together with the client, inspect it completely, paying great attention to the details.

• We remove all breakable objects (paintings, vases, photographs, etc.)
• removing clutter
• cover TVs and computers with a sheet or polyethylene
• disassemble and prepare furniture for processing
• lifting mattresses
• We take cats, dogs and other animals with us or lock them in the bathroom (you can seal the doors with tape)
• cover the fish with a blanket, turn off the air
• close the windows, vents

After the preparation procedure, the client leaves the apartment, we move on to the next stage

— select the drug used for treatment: neonicotinoids, PHOSES, pyrethroids, many component drugs. Recently, we have been working on bed bugs with multi-component preparations (the choice of the drug depends on the region of use and the resistance of the insects, and we have also previously carried out independent treatments or treatments by other organizations)

• mix in the required concentration
• apply the product to the required surfaces
• closing the apartment infuses (exposition)

Cold Mist Insecticides

How many days the bedbugs die depends on what drug is poured into the generator. Most often, insects are poisoned with the following insecticides:

• Sinuzan – causes intoxication when it enters the intestines. Bedbugs die a few hours after contact with the drug. For treatment, use a 5% aqueous emulsion at the rate of 50 ml per 1 m2.
• GET is safe for people and pets. The death of insects occurs after 1-3 days.
• Xulate is a complex drug that contains three active components. Thanks to this, bedbugs do not develop immunity to the poison. According to the manufacturer, all ingredients are enclosed in special microcapsules, which prevents them from being inhaled by humans.

For processing, the substance is dissolved in water

The effect becomes noticeable after just a few hours, but it must be taken into account that Xulat does not act on bedbug eggs, so the procedure will need to be repeated. When choosing a cold fog treatment for bedbugs, you should use multicomponent preparations containing a significant dose of toxic substances.

Such drugs make it possible to increase the efficiency of the technology and help reduce the risk of bedbugs developing resistance to poison.

This is due to the fact that an aqueous solution is used during processing. If a poorly soluble insecticide is used, the effectiveness of the technology will decrease, since it will not be the liquid poison that will be partially released, but a fine suspension from the water. A solid sediment will remain in the tank.

Why is it worth exterminating bedbugs?

Discomfort at the site of a bug bite is only the smallest nuisance. Those affected may then develop allergies. Children are especially susceptible to this. In them it manifests itself:

• redness,
• rashes,
• itching and burning,
• problematic breathing,
• increased body temperature,
• nasal congestion and runny nose.

Ignoring these conditions can cause anaphylactic shock. In addition, in the process of scratching wounds, inflammation begins and pus forms. Victims can easily contract a serious infection.

Bites reduce the level of hemoglobin in the blood. This is especially true in young children. All these unpleasant moments provoke the development of psychological problems:

• fear and aversion to insects,
• fear of being bitten by an insect,
• fear of bed.

These problems provoke panic attacks, nervous tics and breakdowns, problems with night sleep, fatigue and poor concentration. The child's performance decreases and he is tormented by nightmares at night.

In addition, bedbugs are carriers of very serious diseases. Through their bite you can catch:

1. Typhus. Typhus is manifested by: an increase in temperature, damage to the central nervous system, attacks of fever, impaired functionality of the cardiovascular system. rashes. There have not been typhus outbreaks in developed countries for a long time. But its pathogen can live in the human body for a long time and manifest itself when immunity decreases. Timely destruction of bedbugs will help protect against typhus.
2. Relapsing fever. After infection, a person begins to suffer from: attacks of fever, headaches, severe joint pain, bouts of vomiting and nausea. The bacterium produces endotoxin, which negatively affects the liver, nervous and circulatory systems.
3. Tularemia. This disease is carried by animals, but bedbugs can infect humans with it. Infection is manifested by: chills, confusion, fever, pain in the limbs, headaches, vertigo.

The bug can also carry:

• syphilis,
• smallpox,
• anthrax,
• typhoid fever,
• leprosy,
• tuberculosis.

As you can see, bedbugs are not so harmless. If you find them in your home, call a specialist immediately.

Types of cold fog generators

Professional insecticide sprayers are designed to cover large areas. They can only be used by pest control staff. The following generator models are suitable for disinsection of rooms and other small spaces:

• BURE SM B100 – distributes insecticide particles ranging in size from 10 to 50 microns. Using a powerful air flow, the substance is sprayed over a distance of up to 10 meters. The generator weighs 3.7 kg and can process a room of up to 100 m2 in just 1.5 minutes.
• DH-50 - equipped with a five-liter tank into which an insecticide solution is poured. The power of the device is 1.25 kW, the aerosol jet covers a distance of up to 10 m.
• AN-GAE Fog 4.5 – produces particles 5-20 microns in size. The weight of the generator is 2.2 kg, the insecticide is sprayed over a distance of 5-10 m. It can be used not only to kill parasites, but also for disinfection.

A cold fog generator is not cheap. The average price varies from 15,000 to 30,000 rubles and above (add here the cost of the drug). For one-time self-processing, it is hardly worth buying it. The services of specialists will cost a minimum of 1,600 rubles, a maximum of 6,000 rubles.

More about generators

Units that produce cold/hot fog are divided into 2 main groups according to their intended purpose: household and professional.

Equipment from group 1 is much more expensive. Note the difference in size and capabilities. Professional devices hold tens of liters of liquid. This means that with their help, you can clean a large object in 1 approach: a warehouse, workshop, greenhouse, etc.

This technique is not suitable for work in domestic conditions. It takes up a lot of space and is difficult to use. Household generators are compact and can be held with one hand. This type of equipment is designed to work in apartments, houses and other small spaces. To understand the difference between the devices of these 2 groups, you need to compare their main parameters:

1. Model U60-pro. Costs 200,000 rubles. Allows you to process large objects. Power is 1.5 kW, the tank holds up to 54 liters of liquid.
2. Execution Fontan COMPACTSTAR. The unit produces cold fog up to 35 cubic meters. m. Price - 150,000 rubles.
3. Handheld device DH-50 from Korean manufacturer. Power - 1.25 kW. This unit produces a jet up to 10 m long. It is easy to hold with one hand (weight 3.7 kg). Price – 20,000 rubles.

Before starting work, the room needs to be prepared: all corners are cleared, furniture is moved to the center, interior items are removed from the walls, food is removed from the room. At the initial stage, a solution is prepared. To do this, the insecticide is mixed with water in the proportions recommended by the manufacturer. Next, the entire room is treated, a stream of substance is directed onto different surfaces, furniture, and then into the air. At the end of the procedure, you must leave the room for several hours.

Carrying out processing

Exterminators can explain how cold fog affects bedbugs. A cloud of fine particles of insecticide remains for another hour and a half after spraying. Fragments of the insecticide spread throughout the living space, penetrating into vents or cracks in the ceilings. Walls and floors are covered with insecticidal film.

Poisoning of bedbugs with cold fog occurs as follows:

• The chemical is diluted to the required concentration.
• The generator is filled with solution and connected to the network.
• Walls, floors, baseboards, furniture, as well as all hard-to-reach areas are thoroughly treated.
• After the fog settles, the treated living space is ventilated for 60 minutes.
• After completing work with units that form an insecticidal cloud, wet cleaning of the room is performed. To do this, use a soap or soda solution. Use it to wipe all surfaces that households may come into contact with (furniture and interior items).

And it is allowed to wash the floors well only 10 days after manipulations with cold fog. Vertical surfaces and hard-to-reach places are not touched for another 20 days after treatment. Automatic ventilation devices in the apartment must be turned off. And in open areas it is not at all advisable to use a cold cloud.

During the treatment, only exterminators remain in the living area. Upon returning home, the owners perform partial wet cleaning. Rinse dishes, wipe furniture and equipment. In order to not give bedbugs a chance to survive, it will be possible to wash floors and walls only 10-20 days after disinfestation.

Processing is carried out by qualified specialists

The back walls of furniture, corners and baseboards should also be left for a long time without general cleaning. Insects that have found secluded places during manipulation with a cold cloud of insecticide will not be able to sit there for long.

Coming out of their hiding places, they will come into contact with the poison remaining in these places. And also these places are not touched for a particularly long time, since eggs may be hidden there. If the living space has been overly infested with bedbugs or there are deep cracks in the old house, then re-treatment of the premises against bedbugs is required 14 days after the initial manipulation.

When the insecticidal service arrives for the first time, it will explain to the owners the algorithm of actions. Some insist on double pest control to achieve a stable result.

Disinfestation procedure: what does it involve?

The use of hot and cold fog is very effective in the fight against bedbugs and cockroaches, so the number of positive reviews for this method is constantly increasing. Let's look at how this procedure is carried out correctly.

First of all, you need to take the chemical and dilute it with water in the required proportions. Pour the prepared product into a special tank, which is present in the generator. Plug the equipment into an electrical outlet

Carefully treat all the walls of the room, as well as furniture and baseboards, paying special attention to hard-to-reach places. After this procedure has been completely carried out, it is necessary to immediately ventilate the room - this must be done as soon as all the smallest particles have settled

It is advisable that the ventilation procedure lasts at least one hour. Having completed ventilating the room, you need to make a soap solution and thoroughly wipe with it all those objects with which household members have the greatest contact - tables, chairs and door handles, as well as some other objects. Keep in mind that you should wash the floors in a room where treatment against bedbugs and cockroaches has been carried out no sooner than ten days later. Three weeks after the procedure, it is necessary to wash the walls of the room, as well as all baseboards.

As a rule, a hot fog generator allows you to completely rid your home of cockroaches or bedbugs in just one procedure. But in very rare situations, such processing may need to be repeated. There should be at least two weeks between treatments. Such a need may arise in insufficiently favorable conditions, especially where old floors are made of wood, and there is also significant congestion of the living space with unnecessary things. All this together is very attractive to cockroaches.

Actions after disinfestation

Upon returning to the apartment, it is necessary to perform a partial wet cleaning. Rinse dishes, wipe furniture and appliances. To reduce the chances of bedbugs surviving, the floors are not washed for another 1.5 weeks, and the walls are wiped with a damp cloth after 3 weeks.

The back walls of furniture, corners and baseboards also do not wash for a long time. The product should remain here longer - insects that have hidden far away will come into contact with the poison when they come out. The eggs of females are often hidden in these same places.

If there is a significant population of bedbugs or in old houses with large cracks, the apartment must be re-treated for bedbugs - after two weeks. Some companies recommend mandatory double disinfestation to achieve a long-term positive effect.

On the websites of sanitary and epidemiological services, there are often negative reviews that several days after cleaning, insects continue to bite and, therefore, the cold fog procedure is ineffective.

This opinion arises due to ignorance of the stages of development of bedbugs. Most adults will die immediately after contact with the chemicals. But new ones may appear from the clutches after 3-4 days, and after two weeks they grow and begin to cause inconvenience to people.

Precautionary measures

• When you decide to use the cold fog baiting method, you need to understand that it is poisonous not only to cockroaches, but also to people. This is a method with toxicity of 2-3 degrees of danger. There is a risk of poisoning from inhalation of air and from contact with treated surfaces.
• If you decide to carry out the entire procedure yourself, then you absolutely need to be properly equipped. You must wear a special protective mask, and you must also protect your eyes with glasses. Clothing should consist of long trousers and a jacket with long sleeves. Hair must be covered with a scarf or cap, or a jacket with a hood is required. Your feet should be wearing boots, not slippers. You must wear gloves on your hands. Almost no part of the skin of your body can be exposed.

• After you have treated the room, you need to leave it closed for at least four hours, and preferably longer.
• Then you need to return to the room for a few minutes and ventilate it for about 2 hours.
• But it is advisable not to enter the apartment for about a day, or better if you find the opportunity to leave the apartment for a whole week.
• Upon returning to the apartment, before you bring children, elderly relatives and pets, you should do a complete deep cleaning. If you don’t have the time and energy for this, then it makes sense to call a cleaning company, but carefully observe that the entire apartment is cleaned in the most thorough manner, all surfaces are wiped down and washed with detergents.
• The cold treatment process is quite labor-intensive and is worth getting involved in only because it guarantees getting rid of cockroaches.

Security measures

Guaranteeing safety is the primary requirement when carrying out disinfestation. The arsenal of professional services includes special equipment: overalls, respirators or gas masks, mittens. Without personal protective equipment, there is a risk of serious intoxication and an allergic reaction.

Before you start processing, you need to:

• remove children and animals from the premises;
• close all ventilation openings;
• warn neighbors about disinfestation so that they also close the ventilation ducts;
• if the “hot fog” technology is used, then you need to move indoor plants and an aquarium to the loggia or entrance;
• turn off fire detectors;
• processing should be carried out using a special suit, gloves, glasses and a respirator.

After treatment, you must leave the room and only then remove the protective equipment. Upon completion of work, the suit must be washed.

If you have symptoms of malaise, vomiting and nausea, you should immediately leave the apartment, wash your hands, face, rinse your mouth and drink a few tablets of activated charcoal. When the actions taken do not bring results, go to the hospital.

Advantages of our organization

Our company has been exterminating bedbugs with hot fog in Moscow and the Moscow region for more than 20 years. Before choosing this treatment method, specialists will first inspect the customer’s apartment to reliably make sure that it is suitable for him. The examination can be carried out both visually and using special means. It includes:

• the total area of ​​the apartment and each room separately;
• the degree of bed bug infestation in each room of the apartment;
• presence or absence of foci of spread;
• a note about the residence of pregnant women, children, animals, and people with poor health in the apartment.

Based on the results, a disinfestation plan is drawn up, which includes preparing the apartment and cleaning after treatment.

Preparation before processing

Before a specialist arrives and kills bedbugs directly with hot fog, the room must be prepared. Lay out chairs, beds, sofas, remove mattresses from the bed. If possible, move furniture away from the walls. If this doesn’t work, notify the exterminator and he will help you do it. Pack food, cutlery, dishes and clothes tightly. At the time of treatment, it is necessary to take children and animals outside and go out on your own.

Cleaning after treatment

After treatment, wipe the surfaces that you touch most often: door handles, refrigerator, headboards, kitchen table. It is not recommended to wash floors for two weeks - this is the period for which the drugs work, affecting insects that managed to hide from the poison at the time of treatment.

In what cases is cold fog ineffective?

In many cases, you can get 100% results when processing using such products. Sometimes pests remain in the room or appear soon after spraying the insecticide. Possible reasons:

• violation of processing technique, for example, improper preparation, due to the fact that the room is heavily cluttered, toxic substances did not reach the most remote areas that have not yet been sufficiently cleared;
• after completion of treatment, the time interval from spraying to ventilation was not maintained;
• a window or door was open while spraying;
• an inappropriate insecticide was used: with a low percentage of poison, or bedbugs develop resistance to the compounds, so chemicals are useless.

In addition, the lack of results is possible if general cleaning is carried out too early, that is, all the insecticidal solution was washed off from the surface in the apartment

If you have a steam generator and process it yourself

We mentioned the preparation of the room above; prepare protective equipment: safety glasses, rubber gloves, a good-quality respirator and a change of clothes. The result often depends on the chosen product; not all drugs have ovicidal properties (destroy bedbug eggs on contact). But be sure to pay attention that the drug has a prolonged effect (residual after disinfestation). Then the newly hatched bugs within 10 - 20 days will fall under the residual effect of the drug. Working with a steam generator itself is considered a complex process, there are many risks both with protecting yourself and with the surfaces being processed. Hot fog is, firstly, a high temperature and some surfaces may lose their previous appearance, and sometimes even become damaged. Before starting, consult with specialists at the company that will carry out the processing.

Reviews

Viktor Alekseev, 35 years old, Sochi: Buyers do not take into account the danger of contact with a fine mixture. I once used such products. When spraying, it is necessary to use special protective clothing and a respirator. Toxic particles can remain in the air for up to 3 hours, so minimal protection will not prevent poisoning.

Sergey K., Yekaterinburg: We have an office in an old building, the whole house was infested with bedbugs and cockroaches. The girls from the accounting department were just crying, their legs were all bitten, they couldn’t work. Cockroaches even lived in the microwave in the kitchen. It was awkward in front of clients. We tried different poisons - nothing helped. And what’s the point - we’ll poison them, but they come again from the upper floors, from residential apartments. Then the director paid for a service call that carried out steam disinfestation for the entire house. Even the basement was treated. The problem was resolved within 2 days off.

Olga Gorskaya, 43 years old, Voronezh: The cold fog did not help us, we had to use hot fog after it. It took a long time to clean the apartment from poisons. It’s good that it was summer, the children were at their grandmother’s dacha.

Vera Nikiforova, 34 years old, Tula: When I was deciding what to use, I considered for a long time the option of using cold fog against bedbugs, but the reviews finally convinced me. I decided that it would be better to spend a couple of hours later on general cleaning of the poison than to live with parasites. Since then there have been no bedbugs in the house.

Marina Katulevskaya, 33 years old, Simferopol: I was disinfested at home with a cold fog. It didn’t take much time, I mean the procedure itself, there were no bedbugs the next day. We were required to prepare the room, and then I had to do the cleaning.

Tatyana Nikolaevna, Saratov: I struggled with ants in my apartment for a long time. I tried different folk remedies. And she drew paths of garlic, and smeared the dishes with sunflower oil, and placed honey with boric acid in a saucer on the floor. Nothing helped. In winter and summer we ran around the kitchen. She called the service, which poisoned them all with a steam generator. I washed everything and haven’t remembered the ants for two years now.

Anna Shukalova, 30 years old, Vologda: We treated the rooms of the house ourselves. Once upon a time we bought a small generator, since in the private sector there are a lot of pests that constantly get into your home, you have to spray poison often. The procedure does not take much time. It is important to remove all dishes, food, and personal belongings. I wouldn’t recommend treating clothes and bedding either. Otherwise, the method is safe if you use protective equipment.

Anastasia Mezhieva, 41 years old, Moscow: We ordered a pest control service in a private house. At first I thought that the parasites remained, because on the second day they did not appear even in the middle of the day. I called the company that sent employees, they explained to me that first the insects become active, then quickly die. And so it happened.

Marina Alekseevich, Kazan: My husband and I bought an old apartment. We decided to make repairs. They removed some of the wallpaper and baseboards, and we almost felt sick. All the walls were swarming with small insects. My husband said it was bedbugs. I looked on the Internet for various means to combat this muck. I settled on cold steam. The guys from the service arrived with the equipment the very next day and processed everything. The result is excellent. I'm glad because I didn't have to tear down the floors; the poison got into all the cracks. Otherwise, the repairs would have cost us too much.

Elena Sibagatulina, 33 years old, Tomsk: We borrowed a fog generator from friends. A multi-component preparation was used for treatment, but difficulty arose in finding a suit. I had to spend some time on this. It was difficult during processing, since I have no experience in performing such work, but still the result was good. The bedbugs have disappeared.

Galina Khudyakova, 47 years old, Perm: We treated the apartment ourselves, it didn’t turn out perfect, as another procedure was needed. Somewhere, apparently, some surfaces or bug nests were missed.

Inna Kachulina, 31 years old, Nizhny Novgorod: Consumer reviews inspired me, I decided to lean towards the cold fog, as time passed, there were bedbugs at home and they were multiplying. The result is good, but I was not present during the processing; my husband dealt with the issue.

The cost of treatment depends on the area of ​​the room

Signs of bedbugs in the house

Many people notice signs of bedbugs, but do not know what these phenomena signal. But how can you determine that these insects have infested your home and quickly respond to the problem? Signs include:

• Bites. If after sleep you notice bites with a red dot on them, then this is the main sign of the presence of these pests. Vinegars are unpleasant and painful, making them difficult to detect.
• Black spots on bed linen. These are waste products of parasites.
• Shells. Bedbugs have a molting time. If black shells are visible on the bed, this means that the bedbugs are losing their outer shell.
• Larvae and insects. If the pest was discovered by itself or a place where eggs and larvae were deposited was found, then this is the main sign of insects settling in the house.

There are many chemicals available to get rid of these pests. Hot and cold fog against bedbugs are effective. Reviews indicate that it is better to entrust this to specialists, since they know all the intricacies of these procedures.

Approximate cost of cold fog treatment

To understand how the price of disinfestation services for various objects is formed, it is recommended to study the data presented in the table.

If the room is moderately or severely infested, using improvised means will only aggravate the problem, as it will waste time. In this case, you need to immediately use more effective methods. It is recommended to consider cold fog treatment for bedbugs.

The cost of disinfestation of private properties depends on the range of services included in the package

This method will quickly eliminate the unpleasant consequences of infection. You can completely get rid of parasites by following the rules for preparing and spraying the substance. It is also important to clean up as late as possible so as not to clean surfaces of poison.

Is it harmful to humans, animals and plants?

Each insecticide belongs to one of 4 hazard classes. GOST 12.1.007-76 describes them in detail. According to it:

• Class 1 (I) – extremely dangerous substances;
• 2 (II) class – highly hazardous substances;
• 3 (III) class – moderately hazardous substances;
• Class 4 (IV) – low-hazard substances.

The hazard class of a particular product for humans is always indicated on the label and in the instructions. Class 1 substances are practically not used to bait pests. Substances of classes 2 and 3 are most widely used in professional pest control. Class 4 includes the majority of household products that are completely ready for use - aerosols, sprays, crayons, gels, insect traps.

When treating with fog, SES experts can choose drugs that belong to different hazard classes according to GOST. Substances that can actually cause significant harm to health are prohibited from being used in premises where people live and work. Whether using cold mist against cockroaches is harmful depends not on the composition of the product, but on who uses it and how. If the processing is carried out efficiently and safety precautions are followed, then it is effective and does not harm.

A person without protective equipment should not be present directly when the drug is sprayed. When the cloud of insecticide settles, there is no longer any threat of “breathing in” it. Wet cleaning allows you to remove the product from all surfaces that you frequently touch with your hands. After this, it will become difficult to bring toxic components into your eyes or food with your hands.

To keep your pets safe, in addition to the previous steps, you should thoroughly wash all surfaces within 1.5 meters of the floor. This will remove the remaining insecticide from there so that the pet does not walk on it with its paws and cannot roll around in it.

Fog is not dangerous for plants, but it does not bring any benefit either. Contact with the insecticide will not cause immediate burns of foliage or death of flowers, but it is still recommended to remove them during treatment. If you need to get rid of parasites in flower pots, it is better to use special products for plants.

Insecticides that poison humans should not be used in residential areas. But often chemical components that are harmful to humans are effective against parasites. When spraying such substances through a generator, risks arise: the poison remains in the room for a long time and remains after ventilation. In the future, particles may enter the body and lead to poisoning.

Toxins spread throughout the home, not just one room. Therefore, particles can get into the eyes and into food. During processing, for a better effect, professionals increase the concentration of the working substance sprayed into the air, which increases the above risks. Therefore, you need to familiarize yourself with these nuances, check the quality and safety certificates, and only then you can order services and enter into contracts.

Procedure

According to reviews, it is advisable to entrust the poisoning of bedbugs with cold fog to special companies. You can find out the service number at the Sanitary and Epidemiological Station. They will also tell you how much it costs to call the SES. Usually the cost of the service is 900-2500 rubles.

If you have a household generator and all the nuances are known, processing can be done independently. Poisoning bedbugs with cold fog is carried out according to the following instructions:

This completes the procedure. It is important to follow all stages of the procedure, as they affect the result.

Symptoms of a bedbug bite

The bites of these insects are easy to identify because they have clear characteristics. They usually attack at night or after sleep. A bite is detected by:

• itching;
• redness;
• swelling;
• a large number of bites;
• the presence of bites on open areas of the body: face, neck, hands.

If there are bedbugs in your home, you should urgently begin exterminating them. With timely treatment, you will be able to protect yourself from the harm that insects can cause to humans.

Advantages and disadvantages

According to reviews, killing bedbugs with cold fog has its own characteristics. The advantages include:

But the processing also has disadvantages:

During disinfestation, sensors, for example, a fire alarm, can be activated. Therefore, it is preferable to turn off the system during the processing period.

The method is not effective enough in the formation of air currents that blow away the aerosol. Mechanical ventilation must be turned off. It is advisable not to use the method in ventilated, open areas.
