spiders, insects
01.07.2020
Arthropods are frequent residents of houses and apartments. The danger of such a neighborhood is that some varieties of these insects are poisonous and their bite can be fatal.
Therefore, if a black spider appears in the house, you need to know what species it is, how dangerous it is for family members and how to properly deal with it.
Spiders in the house.
What causes spiders to appear at home?
The main habitat of arthropods is forests, fields and gardens. There they find food, weave webs and lay eggs. These residents settle in the house if there are favorable conditions for existence.
The main reason for the appearance of a spider in an apartment is a large amount of food. If there are midges, mosquitoes or flies in the room, then the arthropod will firmly settle in one of the dark corners.
Spiders love darkness, humidity and coolness. Therefore, in the house they are often located behind sofas, armchairs or under radiators. In this case, you can get rid of insects by frequent cleaning - removing cobwebs in all corners.
A man brings small spiders on his clothes and shoes from the street. But if the house does not have suitable living conditions, then they will not stay long.
Help prevent spiders in your home
Repellers will help prevent the spread of arthropods in the house. The most effective device will be the Yastreb company, which is plugged into an outlet. It is easy to use and not dangerous to humans and animals.
In addition, you need to take out the trash in a timely manner, throw away old things and faulty equipment. All this attracts arachnids and gives them a wonderful place to live.
Folk signs
Whether a meeting with a spider will be favorable or not is determined by environmental conditions, time of year or day, movement along the web, position and shape. You can listen to these signs, or you can ignore them. Although why, if superstitions, as a rule, bring positive news.
Let's remember the signs about the consequences of meeting spiders:
- found on your head - get a big sum of money that you don’t expect;
- to see in the morning means good luck for today, at noon (when the sun is at its zenith) - wait for the beginning of a great love story;
- a spider hanging on a thread hangs in front of your face - an unexpected conversation with a person you haven’t seen for ten years;
- appeared on the bathroom wall - to quick changes;
- a spider hanging over the dinner plates means they are talking behind your back or eavesdropping;
- a catching net over the bed - discord or betrayal (This sign will lose its meaning if you simply clean up, check the corners in the bedroom, remove traces of cobwebs from the ceiling, and send the spiders into the yard.);
- if the spider moves upward on the web, expect a promotion, advancement in work matters.
Which houses do arthropods prefer?
Most often, arthropods are found in houses with or without collapsing foundations. They are damp, warm and full of insects that live under the floor.
The more cockroaches, midges and flies in the rooms, the more arthropods there will be. If you get rid of insects, then the spiders will go away.
When cleaning your home, you can use a vacuum cleaner to remove cobwebs. But the bag must be shaken out immediately so that the arthropod does not get out and weave new networks.

Subspecies of black eresus
Due to their wide habitat, several subspecies have formed, which have minor differences:
- Eresus kollari bifasciatus;
- Eresus collari frontalis;
- Eresus kollari ignicomus;
- Eresus kollari latefasciatus;
- Eresus kollari tricolor.
Habitat
You can meet black eresus in Central and Southern Europe and Central Asia. The spider can also be found in central Russia, the Caucasus, the southern Urals and the southern part of Western Siberia. In the Ryazan and Tambov regions, the spider is listed in the Red Book.
This species lives in sunny and dry places. The black fathead prefers bushes; the spider can be seen in meadows, steppes, and sometimes they are found in deserts.
Are house spiders dangerous for humans?
Black house spiders that live in the middle latitudes of Russia are practically not dangerous to humans and their pets. They do not release poison or other substances that could harm health or cause a reaction in the body.
Large black spiders are dangerous only in Sochi and other cities with warm climates. In Siberia and the Urals they do not pose a danger to people. Their poison can only be fatal to small insects. The sprayed insecticide is not harmful to people.
If, however, a person does not know whether house spiders are dangerous, then you can play it safe by treating the bite site with hydrogen peroxide or alcohol. In addition, alcohol tinctures are suitable for processing.
Varieties of arthropods with descriptions
All spiders are predators. They feed on insects and live all over the planet except Antarctica. Few of all the varieties of arthropods are capable of living in human habitation. You can determine the types of house spiders that have settled in a room by the distinctive features of the individual and its web.
Black little spider
Representatives of this species enter an apartment with a current of wind, on a person’s clothing, or by crawling into windows and doors.
Female arthropods reach 3 cm with legs spread out. Males are small and more nimble. The room is located in the corners or in dark places.
The web has a complex, chaotic pattern. They feed on small midges, flies and moths.
They do not reproduce outside their own will. In winter they hibernate. You can get rid of arthropods by frequent wet cleaning and adding essential oils or vinegar to the water.
The domestic black spider is not dangerous to humans.
How not to be confused with a black widow
The black widow is an aggressive and poisonous individual.
The distinctive features of this representative of arthropods are:
- smooth, shiny body;
- a red spot on the abdomen in the shape of an hourglass;
- large size – up to 5 cm including paws.
The house spider looks different: it has a velvety body covered with small hairs and no distinctive spot.
If a person is bitten by a black widow, then you should immediately consult a doctor. Arachnid venom is deadly.
The Black Widow Spider is poisonous.
Long-legged haymaker
It is often called the window arachnid or centipede. The body size is no more than 1 cm. The domestic specimen is distinguished by long legs and an oval brown body.
They live in attics, in the corners of window frames. They weave a web with a random pattern. Representatives of this type of arachnid are shy - if the arthropod is disturbed, it will try to hide. When in danger, he becomes aggressive. It might bite. Its venom is not dangerous to humans and animals, but the bite is painful.
The long-legged harvestman can bite painfully.
Jumping spiders
Horses rarely start on their own in the house. They often end up indoors on a person’s clothing. The jumping ability of an individual is achieved by the special structure of its paws.
This arthropod can move quickly on glass. He has excellent eyesight. The horse is safe for people. It does not secrete poison, because its diet consists of plant foods.
Jumping spiders feed on plant matter.
Gray spiders
The gray arachnid settles in the house in the corners or behind furniture. He is timid and tries to avoid encounters with humans and animals. The arthropod is not dangerous to humans. It bites only for the purpose of self-defense, but does not secrete poison.
An adult can live up to 2 years. The lifespan of males is less - 1 year. With regular, thorough cleaning and adding tea tree oil to the water, the spiders go away.
Gray spiders in the house do not pose a danger to humans.
Hobo spider with poison safe for humans
Representatives of this species enter a person’s home from the street. They look like a haymaker. But the distinctive feature is the brown stripes on the paws and a flattened body with black dots.
The female breeds offspring once a year, but this is impossible in an apartment, since she requires privacy. Therefore, tramps rarely settle in a house for a long time.
The arachnid releases poison when attacking a victim, which kills it. Having eaten the prey, the spider changes its place of residence. But arthropods are not dangerous for people and animals.
The Hobo Spider loves to be alone.
White harmless spider
The white spider is often found in the house. Females of this species are large, can reach 1.5 cm in length. Males are slightly smaller. They weave a beautiful, even web with strong threads.
The white arachnid venom is harmless to humans. But it should not be confused with karakurt.
White harmless spider in the house.
How to distinguish from karakurt
This representative of arthropods enters people's homes from the street. Its poison is dangerous. When a spider bites a person, swelling develops, convulsions occur and the temperature rises. The victim must be taken to the hospital immediately. If help is not provided within 2 hours, there is a high chance of death.
A distinctive feature of the karakurt is its spherical body, which has a yellow tint, which makes it unlike elongated white house spiders.
Appearance of black eresus
Males reach sizes from 0.8 to 1.1 cm, females - from 1 to 1.6 cm. In rare cases, females grow up to 2 cm. The body of the spider is covered with thick hairs. The limbs are thick. Black Eresus has 8 eyes arranged in three rows.
The male's cephalothorax is black, with sparse white hairs. At the same time, there is a red border on its back. The abdomen is bright red. In its center are four round black spots, which may have a white border. The sides of the abdomen are usually black, sometimes mixed with white hair. The first two pairs of legs are covered with even white stripes. The remaining pairs of limbs are black with an admixture of red and sometimes white hair.
In females, the entire body is black. Most often, white hairs are present, which can be concentrated on both the cephalothorax and abdomen. The chelicerae and forehead area are usually yellowish-red in color. The number and length of white-yellow hairs varies depending on the subspecies.
The black eresus is called the “ladybug spider,” because the male spider is similar in color to a ladybug.
Arthropod feeding and web placement
Inside the arachnid's body there are special arachnid glands that produce a sticky liquid. With its help, the insect weaves its web. The strength of the threads is achieved by releasing different amounts of the composition from different glands.
The web is used for the following purposes:
- catching insects;
- flights;
- hiding a clutch of eggs.
This species of arthropod is a toothless predator. They do not catch prey on the fly. The spider attaches itself to the web and waits for the food to fall into its web. The insect begins to twitch, trying to escape. The web oscillates, notifying the hunter that dinner is served.
The predator attacks the prey and injects poison into it, while entangling it with threads. After some time, the insecticide dissolves the insect, and the spider can suck out the nutritional fluid.
Web for catching prey.
Reproduction of arthropods
Arachnids are heterosexual. Males are smaller than females and have brighter colors. The reproductive organs are located in front of the spinning glands.
Males demonstrate their interest in mating in various ways (for example, by clinking their legs on the web). If the female accepts the call, she gives permission to approach her.
After mating, the male must leave the female. It is not uncommon for a female to eat her boyfriend after fertilization.

Ways to deal with house spiders
All arachnids are sensitive to the action of chemicals. The most popular are Butox 50, dichlorvos, Neoron, Dobrokhim FOS. There should be no children or animals in the room during treatment.
After spraying the product, do not enter the rooms for 30 minutes. Then you can ventilate the house by opening the windows. All surfaces must be thoroughly wiped.

How to get rid of it?
If there are a lot of spiders and their presence is annoying the owners of the living space, it is necessary to get rid of them.
There are several ways to deal with uninvited guests:
- clean the apartment thoroughly . Collect all the cobwebs along with the owners sitting in them (we recommend doing this with a vacuum cleaner). Catch all the spiders you see and destroy them. If you don’t dare kill a living creature, throw them outside, away from the house. Cover all ventilation openings in the room with gauze or fine mesh to prevent furry arthropods from returning;
- we fight reproduction . Soak a rag in the bleach solution and wipe all the corners, floors, bottoms and backs of furniture (they prefer to lay their eggs in these places). You can use chemicals such as Dichlorvos or other modern drugs;
- food deprivation . Before destroying arachnids, get rid of all insects living in the house: cockroaches, flies, bedbugs, etc. As soon as food becomes scarce, spiders will leave your house in search of a more nourishing place;
- repair . If you were planning to renovate the premises, now is the time to do it. Any representatives of the spider tribe cannot tolerate the smell of paint and some building mixtures. A couple of days after the start of repairs, arthropods will run away from the house;
- aromatherapy . The most pleasant method of dealing with unpleasant neighbors. Arthropods do not like strong aromas: eucalyptus, citrus, mint, chestnut. You can use aromatic oils or air fresheners with these scents;
- duct tape . Sticky tapes that are used to get rid of flies are also suitable for arthropods. You need to stick them in corners and behind furniture.
Essential oils and scented candles will help get rid of the spider tribe.
When you have managed to get rid of small animals, you need to prevent their reappearance:
- Clean regularly, paying special attention to corners and spaces under sofas and cabinets;
- drive the first spider you see out of the house, because soon numerous offspring may arise from one guest.
