How to destroy bark beetle in wooden structures. How to get rid of the bark beetle in a wooden house

Are you familiar with such an attack? Well, we are sure that you are far from the only person who has encountered her. Therefore, we will learn to exterminate the problem at the very root (otherwise it will be too late later).

A little about the bark beetle: know the enemy in person

So, the bark beetle is a rather small bug, the body length of which almost never exceeds 1 cm. The color is usually inconspicuous brown or black, but in some species it is also brighter. By the way, bark beetles are very close relatives of another group of beetles - weevils.

Any kind of bark beetle is dangerous for living wood: those that feed on the stem mass, and those who devour exclusively roots, and those who prefer needles. But for the house, only the first option is terrible. Moreover, not only adult beetles, but also their larvae will live in the walls. And since almost the entire life of these insects takes place in the thickness of the wood, where they both feed and build extensive passages, very soon the house will simply be worn out from the inside.

First Signs: Recognize Enemy Infiltration

1. The very first thing that should alert you is the appearance on the floor, especially near the baseboards, of the so-called “drill meal”. This is a dry powdery mass that remains as a result of the vital activity of both adult insects and their larvae. It is a small pile at the entrance holes through which bark beetles penetrate into the wood, as well as plaque on the floor and walls. If you see such an alarming symptom, carefully inspect the building. It is quite possible that the moves themselves will be revealed.
2. Pay attention to living trees growing near the house. If a bark beetle lives in them, then it can be easily detected by picking off a piece of bark. Under it you will see wide voids - nesting places for the pest, as well as long narrow passages that it makes while feeding. And by the way, the same characteristic yellow dust can also cover the ground on which the affected trees grow. Look around your yard, do you have one?
3. Listen to the rustles in the house. Beetles lead a secretive lifestyle, and during the day they are almost inaudible. Another thing is the night. Bark beetles make moves in the wood and sharpen it, so you can always hear the characteristic noise.

Prevention is better than cure

If you are buying finished house, be careful in your choice and do not purchase a building that is already affected by a pest. Examine the walls, pay attention to the surface of the wood. Yellow dust deposits, small, sometimes barely noticeable holes, passages under the bark - all these are very bad signs.

Choosing material for construction own house from scratch, also approach the task with particular care. Here's what's important to know:

1. The wetter the wood, the more likely it is to harbor bark beetles. The fact is that the beetle eats practically only juices, and solid he just spits it out (it then becomes that very drilling dust). So the drier the raw material, the less likely it is to be damaged.
2. If you take wood with bark, the risk increases: it is very difficult to see traces of adversity on its surface. Therefore, look at the ends: there should be nothing at all that looks like rottenness! And even more so, no furrows and grooves.

Moreover, even new house must be treated to minimize the possibility of bark beetle. For this, special solutions are usually used.

Processing your home: fighting trouble

And yet, even prevention is not able to 100% destroy the infection. Beetles can come, and then you need to start a real war with them. Otherwise, the house will be completely exhausted. What should be the measures:

1. The most radical method is to completely chop off or even cut down the affected areas. Use only mechanical tools, because electrical (such as grinder) a strong vibration rises, spreading beetle eggs throughout the room. All rubbish, dust, sawdust must be burned.
2. Thoroughly clean all wall surfaces. Caulker - pull out and destroy. With the task of cleaning the walls, a regular vacuum cleaner will do an excellent job.

1. The simplest is boiling water. But it should only be used if the appearance of the wall does not matter. Brew steep boiling water and scald it on the entire affected surface, trying to get into the passages. You can use drying oil, also hot, but again, if the interior is not important.
2. On sale there are many special solutions designed specifically for the eradication of bark beetle in the house. Use them. But here, too, there is a nuance: usually 2 products are needed for such treatment, one of which is an antiseptic, and the other is a fire retardant (fire retardant). They are applied necessarily in separate layers, leaving each to dry during the day.
3. A mixture of turpentine and kerosene is an excellent exterminator of both adult insects and larvae and eggs. It was used by our ancestors. We mix in a ratio of 3: 1 (turpentine and kerosene, respectively) and inject the “treat” with a syringe directly into the beetle passages.

After sanitization, it is necessary to solve another problem - to clog all the passages and exits to the pest. For this, sealants are used. For external lesions, those that are made on the basis of silicone are suitable, and for internal lesions, acrylic ones.

Remember that when purchasing or building a wooden house yourself, you must be prepared to carefully monitor and care for it throughout the entire time of your stay. Nothing will be solved with a one-time measure. The bark beetle may return. Therefore, do not be irresponsible about prevention, inspect the walls and respond in a timely manner to any alarming symptom. We wish you to enjoy a healthy and safe life in wooden house as long as possible!

Video: how to destroy the bark beetle

Bark beetles (lat. Scolytinae)- a subfamily of beetles of the Weevil family, consisting of 750 species, 140 of which belong to the European fauna. The largest of the bark beetles reach a length of 1.5 cm, and the smallest - no more than 8 mm. For country garden bark beetle - very dangerous insect, capable of destroying both young and mature trees, as well as wooden buildings. Recently, climate change has led to the mass reproduction of these pests.

Bark beetle - description

The bark beetle got its name due to the fact that it spends most of its life under the bark. The head of the female bark beetle is sharply convex, while that of the males is concave; on the pronotum, the beetles have teeth and tubercles. The shape of the back is quadrangular, elongated, almost spherical. The elytra are densely covered with stripes or scales. The body of adults is brown, the head is almost black. Bark beetle larva is whitish, legless, worm-like.

Some species of the pest develop only on living plants, others prefer logs, and still others live in both live and cut trees. Labyrinths each type of bark beetle lays in its own way, and by the type of these passages it is possible to determine which bark beetle the tree is infected with. The female bark beetle gnaws through the bark, penetrates into the tissue of the tree, makes moves in it and lays eggs. The larvae that emerged from them feed on the juices and tissues of the tree, continuing to destroy it from the inside. Having pupated, they remain to winter in a tree, and in the spring, an adult insect flies out and looks for a mate.

First of all, the bark beetle inhabits weak and diseased trees, and in this it has an excellent sense of smell, which can distinguish the smell of a healthy plant from the smell of a weakened one. Fruit trees with a damaged root system, cracks in the bark, wounds on the trunk or branches, as well as seedlings and trees that have just been transplanted to a new place can become prey for bark beetles. The fact that a bark beetle has wound up in a tree can be guessed from small holes in the bark, drips of gum on fruit trees and resinous traces on conifers. Pay attention to trees that attract woodpeckers: they are most likely infested with bark beetles. Evidence of the occupation of the tree by beetles is also the presence of small sawdust (drilling flour) on the trunk and at its foot: brown flour indicates that the bark beetles have gnawed only the bark of the tree, and white flour indicates that they have already made their way into the wood. A sign of the last stage of infection is the fall of needles or foliage, the drying of the crown. If pieces of bark fall from a tree, it means that it has already died.

How to get rid of bark beetle

Fight against bark beetle

If you notice signs of bark beetle occupation of a tree, you should immediately take action. How to remove bark beetle? The fight against the beetle should be comprehensive: agrotechnical conditions for garden and ornamental trees, carry out conscientious care of them and carry out regular preventive measures aimed at strengthening the health and immunity of plants.

Make it a rule to inspect the garden regularly so as not to miss the beginning of the occupation. If you find beetle penetrations on a tree, scrape off the bark on them with a scraper, cut off part of the bark so that you can see how deep the pest has penetrated and get to its moves and larvae. After that, treat the affected tree with protective preparations that penetrate deep into the wood and etch the bark beetle. For this, an injection method is used: using a syringe, Confidor, Antisheshelin, Calypso or Empire-20 preparations are injected into the passages made by bark beetles, after which the entrances are sealed with garden pitch. With this method of administration of the drug, the period of its effectiveness is prolonged up to a year.

As for spraying the tree with insecticides (preferably Bifentrin), they should be regular, because after a while the preparations applied to the bark of the tree lose their strength. The meaning of the treatments is that the pupa, which emerged from its cocoon in the spring and climbed onto the surface of the tree, would die from the insecticide. In order for the insecticidal solution to remain on the bark, and not drain into the soil, grated potash or laundry soap must be added to it.

However, you should not abuse chemicals, especially if there are few beetles in the tree. You can try to destroy the bark beetle metal wire, letting her go along the move made by the beetle. But if there are too many holes on the trunk, the foot is strewn with drill flour, like coffee grounds, and the bark falls off in pieces, it is better to cut down and burn such a tree as soon as possible so that bark beetles do not spread over neighboring plants.

Remedies for bark beetle (drugs)

Bark beetle preparations are divided into chemical and biological. Effective biological agents include:

• Bifentrin is a pesticide, acaricide and insecticide of enteric-contact action, a pyrethroid that has repellent properties and is effective against pests at any stage of development;
• Krona-Antip is a biologically active drug based on nematodes, designed to combat bark beetles, woodworms and sapwood;
• Clipper is a unique insectoacaricide of contact-intestinal action, developed for the destruction of tree trunk pests;
• Bi-58 is a reliable and highly effective broad-spectrum insecticide for pest control.

Productive insecticidal preparations against bark beetle include:

• Calypso is a systemic insecticide of contact-intestinal action that allows you to control a wide range of pests in the garden and vegetable garden;
• Antishashelin - effective drug for the destruction of woodworms and their larvae, which is introduced directly into the holes made by beetles;
• Empire-20 is a powerful insecticide against non-flying insects that does not harm humans;
• Confidor is an insecticide of low toxicity to humans with prolonged systemic and contact action against a wide range of pests.

The fight against bark beetle folk remedies

It is very difficult to get rid of bark beetle with folk remedies. They are used mainly for prevention purposes, to scare away beetles. The main task folk remedies- protection and treatment of cuts, incisions, cracks, frost holes and other mechanical damage through which beetles can get inside the tree. As soon as you find a wound, you need to clean it, disinfect it and close it with a garden pitch prepared according to one of these recipes:

• melt 6 parts of paraffin, add 3 parts of crushed rosin to it, bring the mixture to a boil, then add two parts of mineral or vegetable oil to it and boil the composition for 10 minutes;
• melt 1 kg of crushed rosin, add 230 g of drying oil to it, pour this mass into 5 kg of melted paraffin and mix. Keep the var in a warm place;
• 200 g sunflower oil or fat, 50 g of wax and 50 g of rosin melt over a fire, mix thoroughly until a homogeneous mass is obtained, pour into jars and store under a lid.

In order to protect trees from the attack of bark beetles, it is possible to coat the trunks and bases of skeletal branches with a mixture of clay and humus.

There is one more folk way fight against woodworms - the creation of log traps. Throughout the site, at the beginning of the growing season, parts of the trunk sawn into chocks are laid out, which bark beetles willingly populate during the summer, and in the fall these pieces and logs are burned along with all the beetles, eggs, cocoons and larvae.

How to get rid of the bark beetle in the house

The bark beetle is a small insect that in a short period of time can cause great damage to buildings made of wood, as well as finishing materials, such as drywall.

How dangerous is the bark beetle?

The bark beetle destroys the solid structure of the tree, so if no action is taken, then the wooden building may become unusable.

If a puncture appears, then this area should be cut out and burned, if not, it will be possible to get by with just processing.

Before processing, it is required to clean the surface of contamination and prepare yourself (put on gloves, a respirator).

Pest control products

Time does not stand still, and thanks to modern development all kinds of technologies a large number of different means against such insects have appeared. These are various aqueous solutions and impregnations.

You can buy protective equipment in a specialized store. Treat the previously cleaned damaged area with a solution or impregnation of a wooden structure, as well as finishing material. Follow instructions. These funds will not only protect you from bark beetle, but also serve as a preventive measure.

If it is not possible to purchase special products in the store, you can use improvised ones by preparing the solution yourself. Make a mixture of kerosene and turpentine, combine them in a ratio of 1: 3. After cooking, pour the liquid into the holes that the bark beetles have made. Treat nearby areas with drying oil.

You can also contact a special company dealing with such problems. After inspecting the problem area, the arriving team will choose the right way to deal with the bark beetle.

In order to prevent the occurrence of pests in wood, wood should be treated with protective agents even at the construction stage.

A bark beetle can make a house unusable within five years, so if there is a problem, then you can’t hesitate. This is especially true for private country houses and give.

How to get rid of bark beetle

Fight against bark beetle in garden plots

bark beetle larvae

Destruction of the bark beetle - not an easy task, since at the initial stage of infection it is difficult to detect beetles. The effectiveness of their destruction is achieved by certain actions and preparations that do not harm the tree.

Signs of the presence of a bark beetle are:

• gum disease (appearance of dried juice)
• the presence of small particles resembling cereals
• the appearance of characteristic oval holes.

You can also make holes with a small drill. Finally, all holes must be covered with garden mortar. Remember that an easier way to deal with bark beetle is timely prevention.

Pesticide . There are a number of special substances that protect plants from pests. Trunks, branches and even leaves are completely covered with this solution. Seedlings are processed in early spring.

Biological insecticidal preparations can also be used to protect plants. Mature trees are covered with a protective barrier immediately after flowering. During this period, female bark beetles are most active. Processing is repeated after two weeks. When working with drugs, it is necessary to pay attention Special attention its safety. It is necessary to carefully study the instructions and carry out the processing in compliance with personal protective measures.

Antipheromones - special substances that repel beetles. They are quite effective, do not harm a person and are not toxic. This is one of best options for beetle protection.

Timely cleaning . First of all, the bark beetle attacks weak trees, dry branches, broken pieces of bark. If it did not harm living plants, it could be considered an excellent dead wood cleaner.

Traps . The only drawback of this method is that the traps are only effective in large areas, from 10 hectares. For this, it is used old wood, treated with special pheromones that attract insects. Then the bark beetles are destroyed along with the trap.

Details about the dangers of bark beetles on garden plot and how to deal with them can be found in the following video:

Fight against bark beetle in the house and wooden furniture

A pest can enter a house in two ways: along with poor-quality, infected and untreated material, or from nearby affected plants. To prevent infection through building materials, purchase them from reliable companies with quality certificates.

To prevent infection from nearby trees, it is enough to regularly paint the surface of the wooden structure of the house. Having found small holes with small grains, urgent measures must be taken to eliminate pests. After all, in just a few years, a bark beetle can destroy a wooden building.

Wood damaged by bark beetle

How to get rid of bark beetle in infected wooden structures? First of all, you need to determine the area of ​​\u200b\u200bdamage. For this, any thin sharp tool is used, for example, an awl. Pierce the damaged area - if the awl has entered to a great depth, there is no point in saving the element. It must be cut out, and then burned with the larvae.

If the affected area is not pierced, perform the following procedure:

A low-toxic drug is injected into the discovered hole with a syringe. It is necessary to pump the solution several times, after absorbing the previous portion. Finally, after drying, the hole is covered with putty or garden mortar.

If there are many passages on the surface, while the element has good strength, the pest should be destroyed by impregnating the entire surface. For this, it is recommended to use used engine oil. Also, for injections into wood, the surface of which is undesirable to be treated with chemically active preparations, a mixture of turpentine and kerosene (in a ratio of 1: 3) can be used. It fills all the moves. After that, they need to be sealed with paraffin. When using various chemicals, the house will have to be left for several days.

How to get rid of bark beetle? Bark beetle treatment: reviews, tips, photos

More than seven hundred and fifty species include such a subfamily of beetles as bark beetles. Favorite places of their settlement are wood, roots, undercore space. How to get rid of the bark beetle, if the beetles spend almost their entire lives inside the tree, cutting entrance channels in the wood? In the tissues of wood, bark beetles lay their eggs, as a result of which the trees quickly die, and the pests calmly move to new plantings.

The bark beetle, the photo of which can be seen in this article, is an individual from one to nine millimeters in length with an oblong body and short legs. There may be a depression at the end of the body. Differs from other insects in the structure of nests. The passages laid by beetles under the bark with very complex patterns lead to the death of trees.

Danger of bark beetle

How to get rid of bark beetle? To answer this question, let's first find out what its danger is. The fact is that the mass distribution of the bark beetle leads to the destruction of forest plantations over vast areas.

Just one weakened or rotten tree can cause the death of all forest plantations, as bark beetles reproduce very quickly: they bring offspring twice a season.

If you find signs of the presence of insects on the trees, immediately sound the alarm, proceed to the processing of green spaces.

Signs of the presence of bark beetles in the forest

• The appearance of a large number of woodpeckers, constantly chiseling wood.
• The presence of drilling flour on the bark, which appears when the beetles make moves.
• Resin flows from the holes on the trunk, which means that the bark beetles have already managed to lay their larvae, and a new numerous offspring will soon appear.

• If the bark fell off, then the tree is practically destroyed, which indicates in large numbers pests in the forest.
• If the needles of fir and spruce redden, then they are damaged by bark beetles.

Protection of wooden surfaces from bark beetles

To protect against pests, apply evenly ready solution on the surface, without moisturizing it, but only well impregnating it. Carefully handle all the cracks and holes, this is where the beetles lay their eggs. After drying, level the holes made by the pests with putty. It will be correct if when buying building material you will ask the seller about treating trees from bark beetles, impregnating trunks sawn into boards with a special solution. If all this has already been done, you yourself do not need to start prevention. It is enough to carefully and constantly monitor the condition of the wooden surfaces of your house, do everything necessary in time, and then you can be calm: there will be no place for dangerous pests in your house.

Fight against bark beetles

The destruction of the bark beetle is a whole range of measures for the processing, destruction of pests, reducing the risk of their reappearance. Bark beetles are considered the most common and dangerous pests: they feed on the wood of living and dead plants, living tissues are deprived nutrients and the trees are dying. Thanks to their sensitive sense of smell, bark beetles easily distinguish a weak tree from a strong, healthy one. How to get rid of bark beetle? This question worries many people. Given the degree of infection, the removal of the bark beetle is possible.

The most effective methods of dealing with bark beetle

• Clear forest or country cottage area from stumps, fallen branches, diseased, damaged or rotten trees.
• Sand the trees, i.e. remove the bark from infected plantations, wait until the pests appear on the surface of the trunk, and destroy them.

• Constantly carry out proper planting care, this will strengthen the immunity of the forest or your garden.

The destruction of the bark beetle will be problematic if you do not constantly take care of the trees: water them, feed them, cut dry branches. A neglected garden or forest is a favorable environment for bark beetles.

Most Effective protective agent- This is the treatment of green spaces with special solutions in the period from April to August. If the condition of the forest or your garden is very poor, the treatment can be repeated up to four times, with breaks of sixteen to eighteen days between sprayings.

It must be remembered that the destruction of the bark beetle by one method will not positive results. Only the use of all these methods in combination will help you get rid of dangerous pests.

Bark beetle started up in the house

Many owners country houses, dachas, apartments, decorated wooden elements, suffer from an invasion of bark beetles, which for many years can bore into your wooden dwelling, then turning it into dust.

You can detect their presence in the house. When moving, larval worms make a rustling sound that you can hear. Get rid of the insects as soon as they have eaten the whole house.

Treatment for bark beetle will help in this. The fact is that the larvae live in wood for three to four years, destroying up to fifty millimeters of tasty material per year. Then the larvae become beetles and mate again. Bark beetles can reproduce much faster in a fungus-damaged tree.

Many owners of private wooden houses, dachas had to observe holes in the tree and wood dust around them. This left their traces of bark beetles. To check how deep these marks are, take a knife or other sharp object and poke holes in them. Depending on the depth of the damage, cut out a piece of wood, taking the healthy part just in case.

Bark beetle in the country and means of fighting it

Many summer residents know what a bark beetle is. Repeatedly seen small holes on the tree trunk and wood flour around them are all traces of the pest. The holes are small, but the problems are huge. To see if the core is damaged or not, you need to pierce the tree in the places where the beetle moves and check if there is a void there. In the presence of emptiness to the very middle, the tree can no longer be saved. But if the void is shallow, you can try. To do this, cut out the damaged area, capturing the healthy wood around it. All this must be burned at the stake.

If some tree is on your personal plot badly affected by hordes of bark beetles, it is better to get rid of it so that the infection does not spread to other plantings and buildings. As they say, prevention is better than cure. So, preventive measures for country pets are their correct processing. It is as follows. It is necessary to spray the entire tree trunk with the Wood Healer, Antizhuk or other impregnations, they are sold in a large assortment in stores. The spray you prepared will be no less effective. To do this, mix half a bucket of water with green soap and two glasses of crude carbolic acid. Dilute the prepared composition with water in a ratio of one to twenty-five and process your trees.

How to get rid of bark beetle in your home: instructions

As they say, better problem to prevent than to solve it later. Bark beetle in the house is disaster.

• To prevent the appearance of pest colonies, you first need to dry everything in the house, as bark beetles love moisture.
• Look around everything wooden surfaces. If there are a lot of holes, it makes no sense to treat, it is better to cut out the infected areas and burn them. And if there are few holes, then the areas of the tree affected by the bark beetle need to be processed.
• Before processing, you need to clean the surface of dirt and debris, prepare clothes for yourself, a respirator so that the toxic substances with which you will destroy bark beetles do not get on your skin and eyes.
• Get rid of rotten pieces of wood in or around your home to avoid attracting bark beetles.
• If your home is heated with wood, make sure it is always dry.
• Repair any leaks in pipes. The fact is that the bark beetle cannot exist without water.

pest control agent

To find out which remedy will be more effective, refer to the story. Even fathers and grandfathers protected their wooden buildings using linseed oil. If you don't have it, try drying oil. She, quickly drying, creates on the surface protective layer prevents wood decay.

When there were no chemicals, each owner had his own remedy for bark beetle. Many used cold or hot smoke. The only disadvantage of this method is that it does not give a 100% guarantee. Many beetles do not die, but hide and, after waiting for time, again continue to destroy the plantings.

Bark beetle treatment by special means- most effective method pest control. It is better to entrust this work to professionals. Now there are many organizations involved in the destruction of pests.

You can disinfect your home from bark beetle on your own using chemicals, which are sold in a large assortment in stores.

A house made of wood seduces people with its grandeur, practicality and environmental friendliness, pleasant memories of childhood. Therefore, today many owners are building such houses in the country, outside the city. The building made of wooden structures pleases the owners with everything: summer coolness and winter endurance, pleasant atmosphere, comfort, special aroma. However, the joy of being can overshadow the appearance of wood pests.

The bark beetle is a small insect that is harmful to the tree.

One of the ardent representatives of wood pests is the bark beetle, (an insect from the Coleoptera family). An adult is a small bug of black or Brown, reaching sizes from 0.1 to 0.9 cm (f.1). He and his larvae harm living wood, buildings made of it, and even furniture. A bark beetle that has fallen into a tree quickly multiplies and breeds. Its development cycle consists of:

• laying eggs that are "aged" for about 2 weeks;
• the appearance of a voracious larva that lives up to 20 days;
• sleep in the cocoon stage, lasting up to 2 weeks;
• appearance of an adult insect.

The beetle itself is terrible for the house, as well as its larvae. All together they do complex system labyrinths with passages and compartments for queens, larvae, mating chambers, egg deposits, cradles for pupae (photo 2-4). To get rid of the bark beetle in the house completely, you should defeat the adults and their larvae, prevent the birth of adults from cocoons. You can not drag out the process of struggle, the sooner you start the extermination of the bark beetle, the more effective the result will be.

How can I get rid of the bark beetle in the house?

Specialists and ordinary residents of wooden houses who had to deal with the bark beetle offer different ways extermination of the pest population.

1. In the past, parts of the structure damaged by the bark beetle were cut out and burned. Clean, dry wood, treated with a special solution, was put in their place. Therefore, if the affected area is significant, and with wooden walls dust is literally pouring in, then the best solution would be to completely replace the damaged wood in damaged areas.

2. Many owners claim that they saved the house from beetles with a mixture of turpentine and kerosene. With this composition, at a concentration of 3 parts of turpentine per 1 part of kerosene, insects can be etched. To do this, "a potion from a harmful beetle" is drawn into a syringe and launched into places where the bark beetle and its population accumulate.

3. Simple but in an efficient way getting rid of the bark beetle in the house is considered hot water. If the lining allows, then the entire affected area is treated with boiling water, falling into the labyrinths of pests.

4. Instead of water, you can use hot drying oil, vegetable oil, machine mining, trying to get into the places of accumulation of the entire population of the bark beetle.

5. In trading network there are various means from this harmful insect (f.5). Wood processing is carried out according to the instructions. The best are aerosol sprays that allow you to get into the wood in various places.

Attention!
After processing, you need to close the entrances and exits of the beetles with sealant. For internal blockage, an acrylic-based sealant will be required, and for places with external lesions, silicone fillers will be effective.

6. In addition to the above methods, pheromone repellent traps are commercially available. Pheromone traps attract insects to a specific place, a dispenser. Disadvantage: you often have to change the bait, clean the dispenser.

7. Antipheromone traps repel insects: the place is busy, you can’t come here! The disadvantage is that it affects only adult beetles, leaving eggs, larvae, pupae, from which adult adults will subsequently emerge.

8. Application electromagnetic radiation special equipment kills beetles, larvae, eggs.

9. The most effective way to get rid of the bark beetle in the house is to treat the walls health services(f.6). Professionals have specialized equipment and effective drugs. Most effective option control: fumigation with highly toxic phosphine gas. From such a blow, adults die, as well as their eggs, larvae and pupae.

Among the insects living in the garden, the bark beetle rightfully occupies one of the leading positions in terms of the scale of the inconvenience caused. Individuals belonging to this subfamily are quite widespread on the European continent - more than 140 species are known, and there are more than seven hundred varieties in the world. Not differing in significant size - on average, the body length of an adult male or female is from 1 to 9 mm, they can cause harm not only individual trees, but also provoke the death of huge coniferous and deciduous forests.

the only effective method control in this situation is the treatment of bark beetles, performed using modern chemicals that do not harm the ecosystem.

Features of the bark beetle

Thus, just one family per season can increase the size of the population to an impressive size. And the scale of the destruction of forests can be compared with the spread of fire - it will be as swift and merciless as the fire element.

How to recognize the appearance of bark beetle?

Treatment of trees from bark beetle - the only the right way guaranteed disposal of these wood destroyers. But first you need to make sure that the source of the trouble is identified correctly.

Where do bark beetles come from?

Danger of bark beetle

In special bags on their bodies, females carry fungal spores, which also serve as food for them. And on the surface of their bodies there can be bacteria - the causative agents of diseases that are dangerous not only for plants, but also for humans.

In addition, the lack of response to the appearance of larvae and adults in the garden or in the house can lead to such unpleasant consequences as damage and destruction of furniture structures, stairs, truss systems. The subspecies known as the “typographer” is especially dangerous, the invasion of which is noted on the territory of the Moscow region and in northwestern regions Russia (Vologda, Yaroslavl, Novgorod regions). Its larvae are voracious, show incredible activity and feed mainly on conifers tree.

The main methods of destruction of the bark beetle

Among existing methods fight, there are several that are considered the most effective:

• injection therapy - a special solution is fed into the moves made in the wood using a syringe;
• pesticides for preventive action;
• facilities biological protection;
• pheromones and antipheromones;
• mechanical destruction;
• the use of traps;
• professional pest control with special devices and technical means.

Choosing the method that is most suitable for you is not an easy task.

Mechanical methods of destruction

If an insect is found on fruit or forest trees, they can be processed mechanically. In this case, the trunks are carefully examined to detect the moves made by the pest. And, when they are found, a mechanical pressure is applied to the inside of the passage with the help of a curved metal probe, which helps to destroy the larvae and eggs laid by the females.

Upon completion of the procedure, the outer parts of the trunk are treated from the bark beetle special composition. garden var self cooking they are also introduced into the identified passages along which they move under the surface of the cortex. The composition of the tool is quite simple:

• copper-based fungicide (in a small amount);
• paraffin (300 g);
• rosin (150 g);
• vegetable oil (100 ml).

To prepare the mixture, paraffin must be placed in a clean bowl and melted in a water bath, then add crushed rosin to the resulting liquid and bring the mixture to a boil. Next, oil is poured into the composition, after which it is left to boil for 10 minutes. After this period, the mixture is removed from the heat and left to cool. Fumgicide is added to the cooled composition. Apply the agent to the places of detection of moves, as if sealing them from the outside. The same var can be used for the disinfestation of furniture and wooden structures of buildings, corroded by traces of the life of the colony.

Traps with pheromones

For the disinfection of seedlings, they usually use a remedy and preparations for bark beetle, of biological origin - Lepidocid, Boverin. Mature plants are treated at the end of the flowering period. Preparations must be applied carefully, not missing a single centimeter of the area of ​​the trunk, branches and leaves. Among the most popular are Aktara, BI 58, Decis.

At home, highly toxic substances should not be used. The use of the drug here will be more local. In particular, when passages are found, insecticides of the Antizhuk or Confidor series can be injected into them, covering the treated areas with paraffin. The surfaces of walls and other structural elements of a wooden building should be treated with antiseptic impregnations.

If the lesion occupies a large area, the funds should be applied in a heated form. Furniture affected by the passages that the larvae have made must be covered with a mixture of turpentine and kerosene in a ratio of three to one. The composition is injected into the moves made by the pest, and then the surface is covered with paraffin.
