Insect pest - double-tailed: YouTube / HitroUmno Double-tailed is an unpleasant insect that, when it appears in the house, harms indoor plants, spoils food, and also poses a threat to human health. If two-tailed birds have settled in your house, do not rush to panic and leave your home. Take the advice of experienced housewives and get rid of annoying insects.
Appearance of two-way
Double-tailed animals have a white elongated body, devoid of pigmentation. Only the cerci, paired outgrowths at the end of the abdomen, may be slightly darkened. In many species they have a menacing appearance and resemble claws.
Forktails are ancient creatures. Scientists believe that their origin began in the Carboniferous period. This may be why these representatives have a primitive structure.
The two-east has no eyes. They are completely blind, but are well oriented in space thanks to their long, segmented antennae. The antennae have a straight, not curved shape and are directed forward. Typically, the antennae are between half and one-quarter the length of the body.
All creatures of this order have 3 pairs of legs. They are colorless and short, starting on the first two segments of the abdomen. The entire abdomen consists of as many as 10 segments - thus, the legs of the double tail are located closer to the head. These creatures do not have wings.
The size of two-easted birds living in Russia does not exceed 2-5 mm. But in tropical countries there are giant individuals with a body length of up to 5 cm.
What they look like
The insect has several names: earwig, forktail.
The insect belongs to the class Leatheroptera. The two-tailed fish has a dense body with an oblong shape. The size of adult individuals is from 2 to 7 cm. The brown body of the insect consists of tightly fused plates. They give the body strength and flexibility. The tail of earwigs resembles tongs, like a fork with two prongs.
Because of this feature, the insect was nicknamed the forktail. When she senses danger, she arches her body and points her tongs towards the enemy. The tail extensions serve not only to scare away enemies. With their help, the insect grabs food and brings it to its mouth. The older the individuals, the more powerful their forceps. A feature of insects is the absence of eyes. It navigates in space with the help of long sensitive whiskers.
Habitat
The habitat of the two-east covers middle and tropical latitudes throughout the globe, except for deserts, mountainous and arid areas. The vast majority of representatives of the order live in America, but many species are also found in central Russia.
In nature, doubletails live in moist soil, but avoid wetlands. Their favorite places are fallen, rotting trees, wet slopes near streams and ponds, as well as the lower tier of a dense forest, where the sun's rays do not reach due to dense branches. It is easy to detect double-easted fish if you turn over a rotten snag or dig up the ground on the river bank.
Unfortunately, double-tailed birds often settle near humans. They love rooms with high humidity and poor ventilation, so they can live in basements, bathrooms, and under baseboards. It is not easy to detect uninvited guests, since these creatures leave the shelter only at night. Due to their small size and lack of pigmentation, they are invisible. Therefore, two-tailed birds can live in a house for several years, and the owner will not be aware of their presence.
Reasons for appearance
These insects thrive in conditions with high humidity. Mainly because of this, this interesting insect with a terrifying appearance is found in the apartment. As a rule, it appears on the lower floors, as it moves into a person’s home from the basement. If there is a wetland or a river flowing next to a private house, then this insect may be a frequent visitor.
Sometimes it happens that an earwig appears in an apartment or house as a result of purchasing fruits or vegetables. This insect can easily hide in bunches of grapes, in a net with apples or pears, as well as among greenery, such as lettuce, for example.
Factors that influence the appearance of an insect:
- Increased humidity in a person's home.
- The presence of wet, unwrung rags on the floor in the bathroom.
- Excessive watering of indoor plants, as well as a large number of them.
- The presence of holes around the pipes of water supply and sewerage systems.
- Presence of cracks in the floor and around the baseboards.
- The presence of leaks in water supply and sewerage systems, as well as the presence of condensation, which leads to excess humidity.
Nutrition
Twotails feed on humus, but some representatives are predatory and can catch small insects, crustaceans, springtails and other invertebrates living near them. Predatory species of two-easted (pictured above) have cerci that resemble claws. With the help of these projections they grab and hold prey. Herbivorous two-tails (pictured below) have long and straight tail extensions, since they do not need to hunt for food.
Two-tails also eat mycelium threads, microscopic mites, eggs and larvae of insects, berries, young and decaying shoots. Hexapods feed in the dark, finding food with the help of sensitive antennae. They can take food underground to eat during the day. But when the sun's rays appear on the soil surface, the two-tailed plants do not appear.
Life cycle and reproduction
Two-tailed animals are dioecious animals. In all representatives of the order, fertilization is external: the male deposits spermatophores on the soil, the female finds them thanks to special pheromones - the odors that they emit. The female then collects spermatophores and plunges into the soil. Having prepared a cavity for her clutch, she lays eggs.
Unlike many insects, two-tailed insects do not undergo metamorphosis. The eggs hatch into individuals that look similar to adults, but are smaller in size. However, there are still slight differences in the structure of the little two-tailed birds from their parents: they have fewer segments on the abdomen, and many of their organs are not yet developed.
During the process of growth, two-tails molt - they shed the old chitinous shell and form a new, larger one. This process is due to the fact that the chitinous shell cannot increase with the growth of the host. Therefore, arthropods are forced to change it.
Reproduction of two-easted birds occurs in the warm season. These arthropods are very prolific: the female lays over 100 eggs at a time.
Peculiarities
People often call the double-tailed earwig or forktail. However, these are completely different insects. The forked tail is the main feature that unites them. In addition, earwigs have a much darker body than their two-tailed relatives. Read below about what the double-tailed bird looks like and how it differs from an earwig.
Two-tailed and earwig
Earwigs are members of the order Leatherwings. They have an oblong, flat body of brown-chestnut color. Males are larger, their body length reaches up to 1.7-2 cm, females are smaller (up to 1.4 cm). However, in nature there are also earwigs whose body length can be more than 4 cm.
The insects have small eyes, thread-like antennae and membranous wings, which they use only on rare occasions. A distinctive feature of earwigs is their claw-shaped processes - modified cerci located at the end of the body.
The two-tailed fish is a small arthropod that belongs to the order of cryptomaxillary hexapods:
- The body length of adult individuals usually does not exceed 5 mm, but there are also giant specimens that grow up to 50 mm;
- the segmented abdomen lacks body pigmentation;
- Also, the double-tailed insect does not have eyes; their role is played by long mustaches, which are highly sensitive.
The cerci are chitinous claw-shaped processes that form the pseudotail and can be of varying thickness and length. Many people will wonder why an insect needs such forceps. The claws serve not only to capture prey, but also for protection. If necessary, arthropods are even able to shed them, after which the lost appendages grow back. A photo of the double tail is presented below.

Natural enemies
The two-easted bird has many enemies in nature. Birds readily peck at them - perhaps this is one of the reasons why these creatures are nocturnal. But danger awaits them in the soil too. Shrews and moles willingly feast on two-tailed fish and destroy their clutches.
These creatures are also destroyed by soil insects, for example mole crickets. The predatory larvae of many beetles also destroy two-easted beetles. But these creatures deftly avoid natural enemies, as they quickly move between particles of the earth thanks to three pairs of short but strong legs.
Two-tailed fish can exhibit cannibalism, eating small fellows of their own or other species. This is especially true for predatory representatives of the order.
Does the double-tailed snake bite and why is its bite dangerous?
Predatory representatives of the order are capable of biting a person - squeezing the skin with their claws. The cerci are so strong that this little creature can tear the skin. And since these creatures live in damp, polluted places and feed on fungi and spoiled food, inflammation can develop in the wounds.
The bite of the double tail is quite painful. How can one understand that it was the two-tailed one that bitten if the room was dark or the person did not immediately pay attention to the stabbing pain? There is one characteristic sign: on the damaged area of the skin there will be not one, but two small wounds with a distance of 1-2 millimeters between them. Soon after being bitten, they begin to itch and swell.
What to do if bitten by a two-tailed fish? Fortunately, these creatures are not poisonous. But the wound cannot be ignored. It needs to be disinfected quickly. If a person is prone to allergies, it is advisable to take an antihistamine.
Earwig bite. What to do?
The earwig bites humans with its claws only for the purpose of self-defense if it is accidentally stepped on or picked up. The bite is painful, the damaged area itches and swells . In case of danger, instead of poison, a brown, foul-smelling liquid is released .
With a deep puncture, a small wound is formed and blood flows. The bite site should not be scratched; it should be washed with soap and water and wiped with an antiseptic .
It is a common belief that earwigs often crawl into the ear of a sleeping person . Such cases are rare. If this happens, then a few drops of hydrogen peroxide or vegetable oil are placed in the ear so that the insect crawls out. If you cannot get rid of the earwig, then go to the hospital.
Is double-tailed beetle dangerous for humans?
It is already clear from the previous section that two-tailed animals are by no means harmless creatures for people. But the danger of these creatures lies not only in possible bites.
If two-tails live in the bedroom, theoretically, such a creature could crawl into the ear when a person is sleeping. Once in the ear canal, the double tail will cause severe pain. In this case, boric acid will help. It is dripped into the ear, and soon the two-tailed one dies. A dead arthropod can be easily removed with a cotton swab. If you don’t have boric acid at hand, and some creature is moving in your ear, you can drop sunflower oil into the ear canal. It kills all arthropods, as it quickly fills the trachea through which these creatures breathe.
A repulsive appearance can also harm a person emotionally. The two-tailed bug can greatly frighten a child or a person who is afraid of insects. In addition, these creatures appear suddenly and run quickly, which enhances the frightening effect. And for some, the presence of insects in the house will not allow them to sleep peacefully.
Since two-tailed birds hide in damp and polluted places during the day, they can spread dangerous bacteria. After all, at night, while the owners of the house are sleeping, these creatures can walk around the kitchen table, food and clean cutlery in drawers. The threat lies in the fact that the hostess may not know about the dangerous neighborhood and only wonder why the child got sick or the guests were poisoned.
In the garden, doubletails also cause great harm. In the spring they destroy seedlings, and in the summer and autumn they eat berries, vegetables and fruits. Since arthropods appear at night, the garden owner may not even suspect who is spoiling his harvest. Doubletails love moist soil and therefore well-watered beds are an excellent refuge for them.
Treatment
When double-tailed animals bite and the bite is slightly inflamed, they use antiseptic drugs. Before treating the wound, the bite area is washed with soap and water.
- Chlorhexidine;
- Peroxide;
- Iodine.
Among the healing medications used:
- Bepanten;
- Akriderm;
- Fenistil gel.
To prevent the development of allergies, patients take an antihistamine. No specific treatment is required. Use folk recipes such as chamomile and calendula lotions. To speed up healing and disinfect the wound, use a soda solution. It will help relieve swelling and reduce itching. To prepare the solution, take 250 ml of boiled water and a teaspoon of soda, mix the ingredients and use them as irrigation, compresses, and wound treatment.
It is important to immediately treat the wound after biting the double-tailed hook. Otherwise, there is a risk of pathogenic microflora entering, which will lead to a pathological condition of the skin and possible suppuration.
When earwigs bite, there are no serious consequences. Adult insects pose a danger to curious children; the insect will defend itself if the child wants to “play” with it.
Two-tailed and earwig - differences
The two-tailed bird is similar in appearance to the earwig, a representative of insects that has a similar body shape and the same forked cerci at the end of the abdomen. Therefore, the double-easted bird is often confused with the earwig. But in fact, these are different creatures that have little in common in structure and lifestyle.
An earwig, which is confused with the two-tailed earwig.
The earwig is always colored in brownish shades, while the two-tailed one is most often colorless (white) or light beige. There is one more difference: the two-tailed carapace is denser and wider, while the six-legged ones have a soft exoskeleton.
Is there any benefit from two-way?
There are no useless species in the wild. Two-tailed fish are part of the ecosystem and have a role in maintaining balance within it. These creatures are food for birds, insectivorous animals and invertebrate creatures. In turn, the two-tailed insects themselves also destroy many organisms, including forest pests and dangerous parasites - for example, ticks.
Two-tailed plants also play an important role as saprotrophs - little orderlies. They eat decaying plants, berries and dead insects. This is a very important ecological role, since without saprotrophs the cycle of substances in nature is impossible.
But near human habitation and on agricultural land there is no benefit from two-easters. Therefore, we need to fight them.
Where do double tails come from?
Two-tailed insects live and reproduce in the soil and on its surface, so insects are found indoors quite rarely and, most often, by accident. Where do double tails come from?
- Insects can come from the dacha with you on cut flowers, lettuce, and herbs.
- Find yourself in the harvest.
- Live in a bouquet, seedlings or indoor plants that you recently brought into the house.
- In private buildings and on the first floors of apartment buildings, two-tailed birds can crawl independently through open windows and vents in the warm season.
- If two-tailed animals live in a heated basement, they can crawl into the apartment through ventilation, garbage chutes and elevator shafts.
- Two-tailed insects can get into the house by accident, ending up on shoes or pet fur after a walk.
In the Central region of Russia, two-tailed insects are active in the warm season, so the appearance and increase in the number of these insects occurs mainly in late spring, summer and early autumn, depending on the temperatures of the current season.
How to get rid of double-east in an apartment and a private house?
If double tails appear in an apartment or country house, first of all you need to examine all pipes and valves for leaks, check the ventilation and humidity level in the room. These creatures do not live in dry and well-ventilated rooms. Therefore, the very fact of the appearance of double tails is a sign that the house is too damp.
By the way, high air humidity is also harmful for the residents themselves. And in addition to small arthropods, a fungus may appear. Taking it out is much more difficult. Therefore, establishing a normal indoor microclimate is the main way to combat pests, which will also help get rid of related problems.
To reduce air humidity, do not dry clothes in the bathroom or kitchen. If condensation accumulates on the pipes, it must be removed regularly with a dry cloth. In addition, it is important to remove all places where two-tailed insects can hide and reproduce: seal cracks with sealant, look through hard-to-reach places under furniture and household appliances. Two-tailed ducks that live in houses and apartments feed on food waste, so the trash needs to be taken out every evening and food must be carefully covered.
In order to get rid of all arthropods in the house, you can use insecticides. But you need to use chemicals carefully if a person prone to allergies lives in the room.
To destroy arthropods without putting your health at risk, you can use special glue. It is applied to cardboard or paper around the delicacy for two-easts. These could be slightly rotten or simply overripe berries, pieces of banana or apple, as well as bread crumbs. The glue is placed overnight in the places where the double-east was found. In the morning they will already stick to the paper, and all that remains is to throw it away. Naturally, before putting out the bait, you need to clean up and remove garbage, all food and crumbs from the table.
But it’s important not to forget about sticky traps. If a child or pet steps on such a surface, it will not be easy to wash off the glue. Therefore, animals should not be allowed into the room, and children should be kept under supervision.
Insect control
You need to get rid of a specific “neighbor”. First of all, insect habitats are sanitized. You can resort to the services of sanitation workers. Chemical and folk remedies are used.
Chemistry against pest
A number of drugs containing chemical elements that are aggressive towards insects help to effectively combat double-tailed insects in a residential building. For example, insecticides are used:
- Solution "Anti-bug". Treat wooden surfaces. Apply with a brush or spray. It also destroys shashel and wood-boring beetles.
- "Raptor" (aerosol). The insects themselves, as well as their favorite habitats, are treated directly.
- “Mashenka” is a piece of chalk. It is harmless to humans and domestic animals, has no pungent odor, but has a fatal effect on almost all insects, including two-easted insects. Apply to floors and furniture.
Ordinary “Dichlorvos” also copes well with two-tailed water, after using which the room should be left for at least 5 hours and then thoroughly ventilated.
