Bark beetles are a group of beetles with a specific feature - they feed on wood, grow offspring and winter in it. In the European fauna, there are about 140 species, the smallest of them can barely reach a size of 1 mm, and the length of the largest does not exceed 9 mm. In total, science knows about 750 species of bark beetle. And only among tropical species there are insects 1.5 cm in size.
Large forest fires, hurricanes, droughts and other adverse weather conditions of the last few years have led to the fact that the population of bark beetles has grown rapidly, which caused the death of the forest in large areas of the central region of Russia. The Bryansk, Yaroslavl, Tver, and Kirov regions suffered especially severely. According to statistics, in the forests of Moscow Region alone, over the past three years, the beetle bark beetle has destroyed more than 32 thousand hectares of forest.
What you need to know about the pest in order to choose the right control methods with which you can fight the bark beetle if it has populated trees in your summer cottage, we will consider in this article.
How to protect a wooden house from bark beetle, how to get rid?
Bark beetles are insects living in wood. In Europe, they are inhabited by 140 species, science reports about 750 species. Territories that have suffered hurricanes, fires, droughts, floods are a good place for bark beetles to breed. To determine the presence of an individual, it is necessary to know what the bark beetle looks like, its habitat, the process of reproduction, and what it feeds on.
Complete information will help you choose the necessary remedy against the bark beetle, who settled on the garden plot. Individuals often mutate, it is important to determine the method of dealing with them, which has a positive result.
The appearance of the pest is a brown beetle with a small head covered with hairs. The eyes are oval (they are round), set deep, 3 pairs of thin legs, brown wings, antennae, legs with claws, covered with hairs, the abdomen is concave, flat, convex.
Bark beetle in the house
- Description of the pest beetle What harm do bark beetles do? How to detect a bark beetle? Ways and methods of struggle. Home methods to combat bark beetle. Conclusion
Bark beetles are classified as stem pests that feed on the bark and surface tissues of trees. They cause irreparable harm to green spaces and wooden buildings. How to get rid of bark beetle in the house? How to process wood? Pest control methods are available. Let's find out more about them.
Pest Beetle Description
Beetles wood-sawers are common in central Russia. Small insects 0.8–8 mm in size are dark brown or black in color. The body of the beetle is crowned with a head resembling a mace. Elytra covered with thin grooves end with a deep notch. This body shape allows insects to push the wood dust outward, freeing the passage. Inside the tree, the beetle woodworm gnaws through numerous corridors with pockets for future egg laying. Two weeks are enough for larvae to mature. The bark beetle in the house is a serious danger. To get rid of the bark beetle or grinder beetle, it is necessary to take emergency measures.
What harm do bark beetles do?
The bark beetles of the weevil family feed on wood. Under favorable conditions, several generations of small pests appear during the summer period. Larvae are especially dangerous. For a day, one larva eats up to 10 gr. wood. In a short period of time, they are able to disrupt hectares of forest land. In addition to green spaces, parasites destroy wooden buildings, turn floors and furniture into dust walls.
How to detect a bark beetle?
The bugs living inside the tree are mainly nocturnal. They cannot be detected during the day. There are signs that directly indicate the presence of insects in the house. These include:
- The presence of round holes 1-2 mm on the surface of the tree,
- The presence of wood dust near the holes,
- Extraneous sounds at night, rustling and crackling.
Bark beetles in a wooden house do not tolerate mold and moisture. They are settled in healthy, dry wood. For laying eggs, they choose cracks, or gnaw through special holes. With the timely detection of parasites, infected wooden structures can be saved.
Ways and methods of struggle
The bark beetle often populates abandoned buildings. If a wooden house has been desolate for a long time, without the necessary supervision, it is likely that its walls have long been corroded by larvae. To save such wood is almost impossible. The chances of a favorable outcome increase if the pest has been detected quickly. There are the following ways to deal with the beetle woodcutter:
Owners of country houses can try to save the house from insects on their own. If the attempt is unsuccessful, you should seek the help of specialists. High-quality disinfection from bark beetles in a wooden house will help to seriously and permanently fix the problem.
Radical methods will help seriously and permanently rid the house of pests. Furniture eaten by insects is carried out and burned. If any part of the wooden beam is infected, it is replaced with a new one. It is important to make sure that adjacent areas of the tree are not infected. The mechanical method helps in the initial stage of infection. In a running situation, other measures must be applied.
Insects can be destroyed by highly toxic gases. This technique is simple to implement. The infected tree is fumigated with toxic gas. Poison gas penetrates through the pores in the tree and kills insects. The work is carried out by specialists in residential buildings and warehouses.
Biological control methods help to significantly reduce the population of harmful insects in the house. To do this, use special traps - fumigators. A highly effective bark beetle remedy in a wooden house acts on the principle of a pheromone attack. The tool is completely safe for humans. Barrier 500 pheromone traps are sold freely. The dispenser contains a bait impregnated with pheromones attracting woodworm beetles. The tool helps to quickly get rid of the bark beetle bug in a wooden house.
This method has disadvantages. Pheromones attract only adult insects in the summer. They do not act on larvae and pupae. There is a risk of excessive summer of insects attracted by pheromones.
The fight against bark beetles can be carried out using chemical agents. More often they resort to them when other methods do not bring the desired result. The question of how to remove the bark beetle from a tree in the house becomes relevant when there are a lot of beetles. The range of insect control chemicals is quite extensive. The following drugs are considered the most effective:
The above drugs effectively destroy adult insects, their larvae and pupae. After treatment, the effect of the drug persists for several days, after which repeated treatment should be carried out.
Home ways to deal with bark beetle
Effective folk remedies for insect control will help get rid of bark beetle in a wooden house. They can be used in addition to chemicals. Affected areas of wood are poured with a mixture of turpentine and kerosene, covered with hot linseed oil. In some cases, an elementary treatment of wood with boiling water helps.
Before processing walls and wooden structures from the bark beetle in the house, preliminary preparation is necessary. It is necessary to remove insulation material from the cracks, to clean the ceiling and walls of dirt. This is necessary so that the composition penetrates deep into the wood.
After processing, the holes must be coated with silicone or sealant. At the end of the work, the tree is varnished or painted.
Natural wood residential buildings are gaining popularity recently. Environmentally friendly wood perfectly retains heat, while it looks aesthetically pleasing. It is necessary to make sure that the tree lasts a long time. The wood that has undergone appropriate processing in the factory is reliably protected from insects and mold. Building materials should be bought from trusted suppliers. If, despite the precautionary measures, signs of the appearance of insects in the house were found, do not despair. Using the above methods of combating bark beetle, it is possible to relieve the home of pests.
What does a bark beetle look like?
In order to understand in the early stages that the bark beetle has settled on your site, you first need to know what this pest looks like. Of course, different types of insects may look different, but common external features can be distinguished.
Bark beetles are close relatives of weevils, a number of features will help distinguish them from the latter. Unlike weevils, bark beetles do not have an elongated rostrum. On the contrary, their head is tightly connected to the body, resembles a mace in shape. Thin legs lack a pronounced spongy or hairy sole.
Elytra have punctate grooves. Another important feature of the elytra is the presence of a sufficiently deep notch on their rear, called the “wheelbarrow”. A convenient fixture helps beetles to free wood moves from wood. "Wheelbarrow" is surrounded by cloves, which help to keep unsteady luggage. The color of the shell is dark brown, the head is slightly darker than the body, sometimes it seems almost black.
The subfamily of bark beetles has more than 3 thousand species, over 200 of them live in Russia. Most parasites spend their entire lives under the bark of trees. Bark beetles are small black or dark brown beetles, at the end of the body have a characteristic bevel, which serves to remove wood waste. The bevel, bordered by teeth, is clearly visible in the photo of the beetle. This description of bark beetles is easy to recognize.
Females gnaw a passage under the bark and lay eggs. Larvae hatch and begin to make moves on all sides of the uterine. Each larval passage ends with an expanded chamber in which the larva pupates. Young beetles emerging from the pupae gnaw out and fly out. For a year they give 1 - 2 generations.
What harm do bark beetles do?
Both adult and immature individuals are dangerous for trees and wooden buildings. It is the larvae that cause the most damage, since they feed on wood all the time until they pupate. Only a few larvae per year can bring an adult tree to death.
Bark beetles in the house are capable of damaging the supporting structures in such a way that a building, even a solid one, can collapse.
In addition to the numerous moves in the wood, the larvae carry the spores of the fungus, which further accelerates the destruction of the structure or tree.
How to determine if a tree is infected by a bark beetle
It is quite difficult for a non-specialist to do this. Usually, the activity of bark beetles is noticed by drilling flour around a tree lump. Unfortunately, it is washed off after the first rain.
It is necessary to periodically inspect the trees in the garden, noting the first grains of drill flour on the leaves or protrusions of the trunk, slow development, small leaves, drying out individual branches. With a careful examination, you can find smudges of fresh resin, flying holes in the crust. All these signs should indicate infection of the tree with a bark beetle.
Inside the wooden structure, it’s easier to detect the first signs of the beetle populating a bark beetle, since drilling flour is not washed off. In the photo below, individual pest moves are visible, but the wood is already seriously damaged:
If the log walls in the house are sheathed from the inside, regularly inspect the logs in the attic and underground. At the first suspicion, remove all finishing materials and carefully inspect the ceiling, walls and floors.
The presence of even individual moves on the surface of the logs suggests that they can be hopelessly damaged from the inside. In such cases, urgent measures must be taken to save the home.
We destroy the bark beetle in the house
There are several ways to save a house from destruction and destroy a pest:
- treat all wood with special protective agents,
- use folk methods - diesel fuel, kerosene, solid oil,
- freeze the house, as bark beetles die at -30 °, or warm individual boards or furniture at + 65 °.
If it is highly likely that it was not possible to completely destroy the pest, call specialists. They use potent agents, guaranteed to destroy the entire population.
How to deal with bark beetles in the garden
To destroy the pest in the garden, a mechanical method is quite effective - an iron wire. A long section of it inspect all the holes in the tree. After that, treat the trees with an insecticide. This control measure is most effective during the summer period of the beetle. It coincides with the time of flowering of trees and lasts until the end of summer.
You can also prepare and use a special solution:
- melt 6 parts of paraffin,
- add 3 parts of rosin and heat until boiling,
- add 10 parts of any vegetable oil to the solution and boil for several minutes.
For greater effectiveness, a little antifungal can be added to the mixture.
The resulting product must be coated with all the trees, and all the discovered bugs should be burned.
Pheromone traps are an effective tool in the fight against bark beetle. They lure pests into one place where they are easier to destroy. With the help of such traps, you can get rid of beetles not only in the garden, but also in the house.
At the same time, traps have several disadvantages:
- only sexually mature individuals flock to pheromone traps, the larvae cannot be destroyed in this way,
- with the help of traps you can lure pests from all surrounding areas and worsen the situation.
In general, pheromone traps do a good job of attracting bark beetles and are a reliable means of combating them.
Wood infection prevention
The appearance of bark beetles in the house and in the garden is easier to prevent than to deal with them. For prevention, regularly inspect all the trees in the garden and wooden buildings and carefully choose building materials. After the purchase, the wood should be treated with special tools. Choose them based on its purpose. So, logs and boards for a bath need to be processed only specially with preparations. For ordinary buildings, the following tools are used:
- Clipper - contains the active substance bifetrin. The drug is designed for gnawing and sucking insects.
- SENEG INSA - the drug is non-toxic to humans and destroys bugs at all stages of development.
- A similar effect is possessed by the Antizhuk tool.
The last two agents also have antiseptic properties, protecting wood from fungus.
Bark beetle eggs
The beetle lays eggs, from which larvae of the bark beetle appear without legs, yellow-white in color, having an incredible appetite. The larvae are covered with hairs, spikes, and then are transformed into a dense, compressed pupa. The lower and upper wings cover most of the body. The larva lives under the bark of a tree, in wood. Some species live in herbaceous plants, fruits, seeds. A bug emerges from the pupa. The size of the beetle reaches 9 mm. The bark beetle settles in the most succulent tissues of the tree, feeds on plants and mushrooms that develop in the laid passages. Plant-eating individuals. Some representatives pave passages in wood, others breed on herbaceous plants.
How to determine that a bark beetle has appeared on a site
If a small bug (we recall, the length of the insect in rare cases reaches 1 cm) on the bark, you may not even notice at all, the state of the trees is a talking factor that will indicate that a pest has appeared on the site. By what signs can you find out that the trees are infected with a bark beetle and they need your urgent help:
- The needles of fir and fir acquired a reddish hue or began to fall,
- The bark on the trees falls, and under it branched passages are visible, forming special patterns,
- Woodpeckers frequented the site, birds are trying to get beetle larvae from the bark,
- You have found on the surface of the bark or on the ground under a tree drilling flour - a product of the activity of the bark beetle, processed wood residues,
- Small oval-shaped holes appeared on the bark - these can be both the “mating flats” of the pest and traces from the new generation of beetles that have left the tree.
The listed symptoms indicate different stages of infection of the trees, respectively, the earlier you pay attention to them, the higher the chances of saving the plantings.
What is the danger of the bark beetle
As mentioned above, the vigorous activity of beetles leads to the extermination of forests. Let us consider in more detail what exactly these insects are dangerous.
A tree is an object that interests a bark beetle for various reasons. Firstly, this is nutrition for adults, but this is not the main threat.
In the mating season (usually early June), adult insects begin to form families. Bark beetles are characterized by a polygamous family model - one male and 2-3 females. The male himself gnaws in a tree and prepares a move for the future family, after which he begins to exude special pheromones that attract females. После оплодотворения первой самки он оставляет ее продолжать начатую им работу – строить ходы для личинок, а сам готов образовать новую семью.
The biggest damage to trees is brought not by adult insects, but by their larvae, which are distinguished by great voracity, and it is they who make winding labyrinths under the bark. And this is not surprising, because future bark beetles emerging from eggs need to grow and gain strength.
Bark beetle life cycle
The bark beetle goes through four stages of development: an egg, a larva, a pupa, and an adult insect. Almost the entire life cycle of the beetle is closely connected with the tree. An insect egg begins to develop in the subcortical zone of the wood. The female insect lays eggs with one or several heaps in the most juicy layers of the tree - bast and sapwood. In one clutch there can be more than 80 eggs.
The egg phase ends in about two weeks, after which a yellowish-white larva with a pronounced dark brown head appears, at this stage it does not at all look like an adult insect.
Immediately after the birth of each larva begins to build its own move, located perpendicular to the uterine.
Eating wood, it gradually grows, respectively, and the course becomes wider. As a result, the nutrient layer of wood located under the bark suffers greatly. In the most difficult cases, the appearance of the bark beetle can lead to the gradual death of the tree.
Duration of bark beetle development stages:
- Stage eggs - 10-14 days,
- Stage of the larva - 15-20 days,
- Pupa stage - 10-14 days.
Under favorable conditions, one or two generations of young pests may be born that same summer. If the chrysalis does not have time to become an adult by the end of summer, it remains to winter in the tree. And already next summer, if winter is not too harsh, insects will be able to form their own pairs and give offspring. Thus, in one summer season, the bark beetle can increase its population by several hundred times.
Why bark beetle appears in buildings
It is believed that the bark beetle cannot lay eggs in wooden buildings, and this is indeed so. However, wooden buildings still suffer from this pest. The reason for this, as a rule, is the same: when the house was built, its owner did not control the condition of the materials, that is, the house or cottage was built from wood infected by the pest.
Not all elements of wooden houses can be removed and replaced, it is especially dangerous when the supporting structures of a building suffer from the activity of a beetle. The work of the larvae can significantly affect their strength and stability, accelerate destruction. The threat is not only the moves made inside the wood, but also the fact that insects are carriers of fungal spores. Mold completes the work begun by the bug.
Get rid of the pest in the house
How to deal with the bark beetle if you find that the house is infected by a pest? First, do not delay taking action. About the same signs as in the case of a tree can indicate infection of the building. With one small difference - the inlets are located on the structure. One of the symptoms of infection is sounds resembling a creak heard from wood. Usually, the lower sections of the building suffer from the pest, they need to be examined carefully.
If you are a supporter of independent methods of struggle, we can advise you on several folk methods that were used in antiquity.
Folk remedies for bark beetle in the house:
- Even at the construction stage, the log cabin was treated with warm linseed or hemp oil.
- If infected areas could be removed without harm to the building, they were cut down and burned.
- Near the house during the summer, the beetles created a trap in the form of a log; in winter, a log infected with beetles was safely burned.
- A more modern way is the treatment of infected surfaces with used engine oil.
The pest is hidden deeply, so fighting it is quite difficult. What can be done if the insect larvae cannot be reached? If you want to extend your life at home, it is better to seek help from specialists and perform professional processing from a bark beetle.
Prevention of the appearance of bark beetle
Since it is very difficult to fight the bark beetle without professional help, the prevention of this pest is widespread. However, ancient preventive measures relate mainly to the processing of trees, and not buildings made of wood.
One of the options for prevention is the treatment of bark with garden var. Variety carefully cracked small cracks, cracks in the cortex, through which the beetle can penetrate. This measure helped to effectively protect trees from the bark beetle.
Carefully monitoring and caring for the trees is another preventive advice that you will not be in danger of contacting.
A healthy tree that regularly receives fertilizer and care is unlikely to interest the pest. The bark beetle prefers weakened, exhausted trees.
To prevent the appearance of a beetle in a building, it is necessary to properly prepare building materials: dry, ventilate, and processing with special compounds that protect against beetles and mold will not be superfluous.
Professional home and tree processing
For a long time it was believed that the only way to combat the bark beetle is to destroy the centers of its habitat. Infected forest plantations were cut down and burned to prevent the bark beetle from infecting even more trees. To protect the house, only pre-processing of timber was used.
Today, to combat dangerous wood pests, there are more humane methods of control that are actively used to efficiently and quickly destroy bark beetles on trees and in houses.
We are talking about the professional treatment of infected areas with special insecticides that exterminate the bark beetle.
Modern professional processing from the bark beetle is a set of events developed by specialists.
Three areas of impact:
- Surface treatment of the cortex with contact insecticides,
- Deep processing of the forehead and subcortical layer,
- Injection into the trunk, which includes not only an insecticide, but also minerals that enhance the immunity of the tree.
In the case of processing the building, specialists also use three types of exposure, however, the injections contain only insecticides and substances that protect against mold and bacteria.
Deep insecticidal treatment is performed using special equipment - a hot fog generator or a fumigator. The hot mist generator converts the insecticidal composition to a vapor state, hot steam easily penetrates into the deeper layers, where larvae or adults are usually found during egg laying. During fumigation, insecticides are converted to smoke, which also carefully processes the layers of wood.
As a rule, during the first treatment, the bulk of the pests die, the larvae and bugs remain inside the tree, but they cease to destroy it.
The procedure is relevant for both old buildings - allows you to stop the destructive activity of pests, and for new buildings - reliably protects from bark beetles. Processing methods are recommended for the processing of any wooden buildings (cottages, sheds, barns, etc.), including for residential buildings.
Advantages of professional processing from the bark beetle
Today, the professional processing service from the bark beetle is especially relevant for Moscow and the Moscow region. The proximity of gardening houses and cottage villages to infected forests creates a dangerous situation.
Unscrupulous developers can use the infected forest for construction, with such a proximity of the source of infection in the summer cottage, the bark beetle can easily settle.
Professional processing from the bark beetle has the following advantages:
- It creates a preventive barrier that prevents the appearance of a bug on the trees of your site,
- Quickly and reliably destroys the pest inside buildings,
- It does not negatively affect people's health and the ecology of the site as a whole.
The only condition on which the processing efficiency depends, the invasion of the bark beetle must be noticed in time so that the service specialists can help you.
Types of bark beetles in our country
We have 4 species of individuals, one of which is the most dangerous bark beetle typographer.
Beetle bark beetle typograph
He prefers to settle on firs, pines, cedars and is a serious pest of the forest. The beetle has a dark brown body in the form of a cylinder up to 5.5 mm long, pubescent by hairs, feeds on the bark of coniferous trees. The main food of the pest is spruce, cedar, larch. The beetle especially likes to settle in wet spruce forests, breeds in fresh windbreak, windfalls, logs in timber warehouses, logging residues, in the wood of sick, weakened trees.
The bark beetle typographer is well known to foresters. This is one of the most dangerous forest species. Inhabits the territory of Europe, Siberia, the Far East. It is found on Sakhalin, Kamchatka. It was discovered in Kazakhstan, Tajikistan, Georgia, Turkey, Korea. Externally, this parasite differs from other individuals in its body shape: its back, which has a wide recess with sharp edges. Using this feature, the pest removes sawdust from the inside of the wood to the outside.
A characteristic feature of the typographer is he does not live on dry trees.
How to determine that a wooden house is in danger?
Characteristic marks from bark beetle on a board
If a bark beetle appeared in the house, then traces of its vital activity can be recognized:
- according to external signs - small holes and sawdust similar to dust appeared on the wood,
- by sound - you can hear a crackle.
In the first case, the house can still be saved, in the second, the fight with the bark beetle can be lost.
Can a woodbug live in a stone house?
Beetle damage to wooden floors
Yes. Furniture, other interior items, fully or partially made of wood, can become a pest settlement site. This can happen if insect-infected trees grow near the apartment building. The beetle typograph and other species of individuals pose a danger to living trees, mainly conifers.
They live in the bark and bast, in parts of the tree where the bulk of the juice passes, carrying a fungal infection, destroying seedlings, mature trees and shrubs. Once on a tree, the pest with the help of pheromones spreads information for its relatives about the availability of food.
The whole family falls on a tree, lays eggs, from which larvae appear, which are especially dangerous for wood. Separate elements of the house, interior and exterior items made of such material will gradually be destroyed.
When using wood in construction, it is necessary to carefully consider the material from which the construction is planned and the manufacture of wooden products. Otherwise, you will subsequently have to deal with the bark beetle in the finished house.
In which types of wood bark beetles do not live, and which ones do they like the most?
Bark beetle life
Previously, bark beetles were found only in diseased plants. They were called the orderlies of the forest. Now they can be found in healthy plantations, weakened trees, shrubs, young plants. There are omnivorous pests and narrowly specializing in certain types of plants.
Bark beetles can be found in coniferous, deciduous, and more often even in mixed forests. The conifer responds to the presence of a beetle by pouring it with a strong release of resin. After a while, the tree ceases to fight, yielding to a large number of insects, dies. Beetles do not really like bitter tree species, for example, aspen, teak.
To protect trees from bark beetles, you must:
- to clear the area of trees, stumps and dead wood previously affected by the pest,
- carry out protective treatment of trees from bark beetles and other pests every year.
Protecting trees from bark beetle
Healthy, weakened, and diseased trees need protection. Treatment for protection against bark beetles must be carried out from late April to late August. The number of treatments is from 1 to 4, the most important of them is the first. It is necessary to carry out the whole complex of protective measures aimed at general improvement and raising immunity of the stands.
How to save a frame, wooden house?
What harm can beetles cause to a wooden house?
Beetles have the ability to fly, populating new places with larvae. It becomes clear that protection from the bark beetle is required, which destroys the beetle larva. If the material is not treated with special impregnations, the beetle can lay eggs, subsequently a larva will appear, causing the main harm to the wood.
When building a wooden house, use wood peeled from the bark, without external signs of the presence of a bark beetle. When constructing a frame house, use lumber according to our recommendations, carefully remove all the obzol on the boards.
The main enemies of wood can be considered grinder beetles living in forests and in houses. As food, they choose living trees, a wooden house, furniture.
Preventing the settlement of beetles, it is necessary to treat the wood with a special bioprotective substance, a solution.
For effective processing, it is important to know the characteristics of the wood species. Unstable types of wood (pine, spruce and other soft species) must be handled more carefully.
Bioprocessing products can be divided into several groups:
- antiseptics in aqueous solution,
- oily solutions
- substances based on organic solvents,
- combined formulations.
Means against beetles antijuzh from the Neomid company
Organic substances must be used carefully, as they are toxic. In addition to the treatment itself, it is necessary to adhere to preventive standards. The condition that impedes the settlement of individuals is good ventilation of both the building material and the places of its storage.
Effective remedy for bark beetles
Building logs must be cleaned of bark, subjected to special treatment. Protection against bark beetle can be PROSEPT 42 or Prosept Ultra.
Timely processing of wood will prevent the appearance and development of beetles.
When erecting a structure, it is necessary to ensure the further safety of all wooden structural elements. Traditionally, the process of building a wooden house looks like this: the first layer is stretched vapor barrier, then the insulation and wind protection, completes the design of the ventilation gap and finishing material (siding). Moisture, tending from the inside of the house to the outside, encounters a vapor barrier, a dew point occurs, and condensation forms. Thus, good conditions have been created for the propagation of bark beetles in a wooden house, the germination of fungal spores, although the destruction of wood that has begun will not be visible for a long time.
The point of view of specialists in construction physics, technologists working in wooden housing construction - vapor barrier is not needed for insulation of a wooden house. For a permanently operated house, vapor barrier is harmful. Internal sources of moisture: people's breathing, steam from cooking, moisture from watering domestic plants, a bathroom increases humidity.
Beetles may settle after construction
With open ventilation shafts, door and window openings, the structure becomes accessible to beetles. In case of detection of insects, it is urgent to take all measures to destroy them. And the most important condition for success is timeliness.
An adult woodbug lives for several weeks. His goal is to find a pair for breeding, lay eggs. The bugs' years last from April to July. At this time, they are most vulnerable. To lay eggs, they make holes in the wood or use ready-made cracks. Some pests live in symbiosis with mold. They use wet wood for breeding fungus. The best place for parasites are old boards, so you need to use a special tool to process all the boards from the bark beetle, which will not allow the beetle to lay eggs.
Bark beetle eggs
The bark beetle larva eats 50 mm of a wooden beam 150x150 mm annually. A small bug breeds rapidly. From a hatched bug, tens of thousands are born. The bark beetle typographer lives in wood at a depth of 1 millimeter, where the beetle females lay larvae. Two months later, new bugs emerge from the larvae, and the life cycle of the parasites continues.
What tool will help get rid of unwanted guests?
Beetles that damage wood are different in size and appearance. Unites pests food - wood. Therefore, they like to settle in houses, baths, in different wooden rooms. Specialists offer different methods of protection against bark beetle, inventing methods of control: protective coatings and impregnation. You can also use the old-fashioned methods of removing bark beetles. Among them:
- diesel fuel, acid, kerosene,
- extrusion of holes
- drilling holes.
- the use of Raptor, Fumitox,
- wood heating
- the use of electromagnetic waves and microwave,
- traps with odors attracting individuals.
The most effective is the professional way to combat the parasite. There are organizations using special preparations of wet aerosol treatment, generators of hot, cold fog. Существует также способ избавления от короеда, разработанный и проверенный специалистами, который имеет прекрасный результат. Это проведение фумигации дома (древесины) с использованием газа ФОСФИН, который признан лучшим средством как против взрослых жуков, так и против личинок, которые наносят самый большой вред древесине.
Regardless of which method of bark beetle control is chosen, after treatment, already damaged areas of wood should be disposed of, if possible, replace all elements damaged by parasites
