How to get rid of poplar moths in an apartment? Does it bite and how to fight it?

Poplar moth (Lithocolletis populifoliella) is one of the varieties of nocturnal winged pests. Thanks to the bright pattern on its gray velvety wings, it is called the Pied. The period of distribution of the small insect occurs during the flowering of the poplar. Moths breed in the fluff and along with it end up on balconies, houses and apartments.

Moths do not damage clothes like other representatives of the species. It selects household appliances indoors, penetrates them and lays eggs, causing the devices to malfunction. Since there are few effective means to eliminate parasites, preventive methods are used.

Where does the poplar moth live?

There are many nocturnal inhabitants found in nature. This variety is most common in the Caucasus, in Central Asian countries (Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, Tajikistan) and in European Russia.

The parasite prefers regions where balsam, pyramidal, sweet-scented and laurel-leaved poplar grow, and avoids areas with black and Canadian poplars. Leaves wild forests unattended.

On the South American continent there is a large subspecies with a wingspan of 7 cm and above.

Habitat of the poplar moth.

Thanks to their coloring, insects are invisible during the daytime. In the evening, they gather in the light of lanterns, cover the ceiling, fly into open windows, into entrances, and land on people.

Unwanted guests do not allow the home to be ventilated. Colonies of the moth quickly fill electrical appliances, chandeliers and lampshades.

White fluff is a favorable environment for the parasite to reproduce. The summer heat protects against the growth of pest numbers. Cool summers and warm winters, on the contrary, contribute to an increase in the population and lead to sharp surges in numbers and invasions.

Habitat, lifestyle and nutrition

In nature, the moth lives in those areas where balsam, fragrant, pyramidal poplars grow:

• in the European part of Russia;
• on the territory of the Caucasus;
• in the Central Asian region.

Adults do not feed. They live off what they have stored while in the caterpillar stage. But the larvae are distinguished by their extraordinary gluttony. They eat young leaves:

• drain;
• pears;
• apple trees;
• poplars and other trees.

Just one larva can gnaw a hole with a diameter of about 2 cm in a leaf. If there are many pests, the trees may be left without foliage as early as July-August.

Pest

Penetrating into a person’s home, butterflies settle in chandeliers, lampshades, electrical appliances, containers with bulk products, and dried fruits. They also love various secluded places - behind furniture, radiators, etc.

What does it look like

The name “poplar moth” is considered conditional. Entomologists classify the insect as a subspecies of the Butterfly family. Because of the characteristic marks that the small pest leaves on the foliage, it is called a leaf miner.

Moths are distinguished by narrow, blade-shaped wings edged with fringe. The front pair is brown with small white and brown contrasting inclusions, the back pair is shorter, steel color. The wingspan of an adult insect (imago) is 6-10 mm, the average length is 5-8 mm. Such colors and sizes make the moth invisible against the background of trees.

Cocoons hide in cracks and crevices of houses, bark, hollows, fall into the ground with fallen leaves and continue to live after wintering. At the end of spring, harmful insects fly out and actively mate.

How to recognize an insect

The greatest damage from the pest occurs in urban green spaces. The main food is poplar, but the parasite does not ignore other plants.

You can recognize an insect by its characteristic features, including:

1. Leaf fall. Moth colonies eat the foliage, causing it to fall prematurely and the branches to freeze. In such cases, many trees die.
2. Moves of different configurations. Depending on the type of tree or plant variety, the pestle makes pinpoint punctures, bizarre passages of white and yellowish colors, and grinds off the entire surface.
3. Through holes in young leaves (mines). The caterpillars choose a place for pupation in fresh greenery, eating large holes with a diameter of 1.5-2 cm.
4. Spots on the crown. Damaged plates quickly turn yellow, fade and fall off.

Old trees are more difficult to tolerate pest invasions.

Destruction of butterflies on the street

The following are considered environmentally friendly methods of controlling poplar moths used outdoors:

• autumn destruction of old fallen leaves;
• attracting entomophages (riding beetles) to the site, used as food for adult moths, larvae and egg-laying moths;
• inspection and manual removal of infected leaves; Poplar moth larva.
• the use of special sticky traps;
• flush;
• using spring plant oil to repel insects;
• the use of non-woven material to cover low-growing crops (cucumbers and flowers) in order to prevent reproduction;
• sanitary pruning of tree crowns;
• replacing poplars with trees that are unattractive to this pest.

In some cases, the use of chemicals cannot be avoided:

1. Spraying the trunk, crown, and tree trunk area with pesticides (karbofos). It is aimed at destroying larvae; this toxic substance has no effect on adults and pupae. Compliance with safety precautions is considered a prerequisite for the use of toxic substances.
2. The use of paraffin-based products that have a negative effect not only on moth larvae, but also on moth eggs.
3. The use of ecological preparations made from plant raw materials - pyrethrum (from Dalmatian chamomile). Affected trees require weekly treatment.

When poplars are massively infected with variegated grass, they are completely cut down.

Stages of reproduction

One complete phase of the poplar moth life cycle is 2-3 months:

1. Mating occurs in mid-spring.
2. In May, the female lays alternately up to 32 eggs on the underside of last year's leaf. The eggs are oval in shape, flattened at the edges, covered with the secretion of the gonads. They have a rough texture, matte, with a diameter of 0.2-0.3 mm.
3. In 1-1.5 weeks, larvae form, which climb into the leaf plate and are covered with a thin film. At this stage of development, they vigorously eat greens, accumulating the necessary nutrients.
4. After 2-3 days, young caterpillars 3-5 mm long hatch. The shape of their body is transformed 5 times - from legless and pale, the caterpillar turns first into white, then into lemon with 2 pairs of legs. Eats only fiber.
5. A loose cocoon of cobwebs forms in the through hole. The development stage lasts from a week to 10 days. The sharp cocoon of a light brown hue reaches 4-5 mm in length.
6. From late July to early autumn, the pupae turn into butterflies and live for 3 days.

Stages of moth reproduction.
Each adult strives to lay as many eggs as possible. Suitable places for breeding are bags of flour, cereals and dried fruits.

What does it eat?

The main source of food for the insect is poplar. Caterpillars eat green foliage, and adults find food in the tree trunk. In the cold season, they make do with fallen poplar leaves and linden bark.

In addition, the moth also likes to profit from other plants, these are:

• fruit bushes and trees (pears, apple trees);
• hardwoods (aspen, maple and linden);
• flowers (rhododendron, roses, violets and chrysanthemums);
• greens (lettuce);
• vegetables (cucumbers, etc.).

The moth eats each green space in different ways:

• intersecting paths remain on the crown of apple trees;
• brown burrows appear on pear trees;
• rhododendron foliage is completely eaten;
• through dots and curly patterns are visible on the rose bush;
• cucumber and violet plates are distinguished by narrow paths with whitish dots.

Signs of plant damage

The fact that poplar moths have appeared on the trees can be understood by the fact that traces of the vital activity of caterpillars appear on their leaves. Their shape depends on the type of wood:

1. On the leaves of apple trees, the passages can be round or serpentine.
2. Brown or beige marks appear on pear leaves.
3. Small holes appear on rose leaves.
4. Light passages and dots are visible on damaged lettuce and violet leaves.
5. White dots can be seen on cucumber leaves.
6. Light-colored zigzag marks will appear on chrysanthemum leaves when infected.

Do poplar moths bite?

The moth cannot bite a person; it can only cause psychological inconvenience and disrupt the cozy and comfortable atmosphere of a house or apartment.

Is it dangerous for humans?

The parasite is not dangerous to human life or pets.

Poplar moth is absolutely safe for humans.

Poplar moth, unlike rodents (rats, mice) and some insects (lice, mosquitoes, flies, bedbugs), is not a carrier of severe infectious diseases, and therefore does not harm health.

Having flown into a room, moths do not spoil clothes and food, but leave marks that are difficult to remove on furniture and home textiles.

Electrical installations, equipment and lighting fixtures suffer from moth infestations. Insects flock to the light, get into chandeliers and lampshades, and lay eggs in equipment, damaging and dirtying it.

The presence of uninvited guests in the house irritates the owners, so all available methods of control are used.

Ways to fight in an apartment

The main rule for effective control of harmful insects is that all steps are taken before the poplar begins to bloom.

In the event of pest penetration into a home, before choosing a method of destruction, it is necessary to determine the stage of its development.

To combat this species, there is no drug that can simultaneously cope with both larvae and adults.

You can fight moths or prevent their appearance in your apartment in the following ways:

1. Installing a mosquito net with small mesh on the windows (if not available, use gauze). Such a barrier protects the room if there is a danger of an adult insect entering it.
2. Use of fumigators. Small and economical electrical appliances operate from the mains, electricity consumption is only 3-5 W/day. The device is refilled with modern insecticides that are harmless to people and animals in liquid form or in the form of plates.
3. Clutches of eggs have to be destroyed in cracks and holes using a vacuum cleaner.
4. The use of insecticidal preparations in the form of sprays and aerosols against adult moths. Such means kill both flying and crawling individuals. After spraying, wet cleaning and airing of the room are indicated.
5. An effective method of control is to install glue traps, which the insect is afraid of.

With the first frost, the pests die. Next season, it is recommended to use preventive measures to prevent mass invasions. Since mid-spring, municipal institutions have been carrying out special treatment of plantings.

Types of funds

It is impossible to achieve complete disappearance of the pest in one go. Many areas are addressing the problem ahead of time. In the fall, fallen leaves are destroyed, and in the spring, the crowns, trunks and tree trunk areas are sprayed with chemical compounds.

It is recommended to choose poisons with caution.

Urban landscaping uses plants that attract natural moth regulators. Entomophages eat up to 60% of moths.

In addition to preventive measures, the following chemicals and poisons are effective in combating the poplar moth population in urban environments and garden plots:

1. Numerous clutches of eggs and caterpillars are destroyed by compounds that contain paraffin or karbofos. The drugs are ineffective in removing adult moths. Toxic substances can damage other crops; the proportions specified in the instructions must be strictly observed.
2. Safe insecticidal mixtures of pyrethrum (Caucasian chamomile) in liquid or powder form are used against caterpillars and butterflies. A fast-acting composition without a strong odor has a paralyzing effect. Diluted and applied in the morning or evening up to 7 times per season, with breaks of 4-6 days. To destroy the pupae, the solution is poured into the ground.

Tree processing.
Since insects quickly adapt, are highly resistant to many poisons and are not afraid of pesticides, it is recommended to alternate drugs or combine them.

With numerous outbreaks, the number of miners is reduced in a radical way - poplars are cut down and other tree species are planted.

Traditional methods

Experienced gardeners and summer residents use the following methods to kill moths:

• cleaning infected trees with strong water pressure - acts as a deterrent, helps get rid of a large number of individuals, and interferes with reproduction;
• boards with glue or special baits from a specialty store;
• settlement of ichneumon beetles on the site, in the greenhouse, eating imagoes and oviposition;
• inspection of plants and mechanical removal of damaged leaves;
• to prevent reproduction, low-growing crops (flowers and cucumbers) are covered with non-woven fabric;
• oil of spring crops applied to the foliage can repel the pest.

The insect will not disappear completely. The methods are effective for reducing the number in the current period.

Chemicals

Anti-flying insecticides will help against pestra. They must be used carefully, remembering that insecticidal aerosols are harmful to health, especially for people with allergies.

In addition, they spread an unpleasant odor. Aerosols are used as follows:

1. All surfaces are treated with the product, including cabinets, cabinets, and household appliances.
2. After waiting a couple of hours, the furniture is wiped with detergent.
3. The room is well ventilated.

Among the sprays, the following are highly effective:

• Extramit. By spraying the product, you can forget about moths for six months.
• Clean house. Used in small houses, it helps to quickly get rid of adults and kill larvae.
• Armol. Does not harm furniture and destroys butterflies at all stages of development.
• Raptor. Has a pleasant lemon scent. Safe for people.

Fumigators are widely used against moths. They do not affect people or pets, but they do kill insects. The most popular products are Reid, DiK-3, Mosquitoll. They show results over large areas and are effective against most types of moths. Before using the fumigator, you should assess the degree of infection of the apartment. If it is high, it is better to resort to more effective methods.

When you turn on the electrical device, the plate with a specific anti-moth composition begins to heat up. Aromatic fumes affect the respiratory tract of insects and the chitinous coating, provoking the death of not only adults, but also larvae. They act more slowly than sprays. The plates help get rid of insects in a few days or weeks, depending on the severity of the problem.

In the store you can purchase chemical repellents for harmful insects in various forms, including aerosols.

Sections are another popular remedy that will help drive away moths in an apartment. They are hung on walls or in closets. The substance contained in the drug kills butterflies, but does not harm the eggs. Sections based on essential oils diffuse a pleasant aroma of herbs or fruits into the room.

After using them, it is advisable to ventilate the room, but you must first install mosquito nets to prevent the entry of new insects.

It is recommended to spray chemicals in May, when the moth is active and ready to reproduce. Insecticidal coils that repel pests have a good effect. They are installed in loggias and on balconies. Instead, you can use scented candles that contain poison.

Various tablets and briquettes are produced against moths, which are placed in places where insects accumulate. The vapors they emit prevent insects from laying eggs. Although the products are effective, in high concentrations they are dangerous to human health.

Tablets can be attached to the top of the wall. They will repel insects, preventing them from laying offspring. It is better not to be in the room while the tablets are in effect, and after using them you need to thoroughly ventilate the room.

Important! When using chemicals, it is important to read the instructions - each drug has its own algorithm of actions.

Where to go for help

Spotted grass is a dangerous pest along with ticks and bark beetles. Parasitizing urban green spaces and garden crops, it causes premature leaf fall and impairs the viability of trees.

Citizens complain to various authorities. To clear a large number of plants on which the pest lives, it is recommended to draw up collective letters of complaints to the territorial prefectures from residents of the block or entrance.

Based on the application, the city authorities assign special groups that assess the condition of the trees. Based on the results of the inspection, utility services treat plants with insecticides, cut off affected branches, or cut down poplar groves and plant new varieties.
