What insects are the most dangerous for wood and what do you need to know about the larvae of wood pests? Is it possible to detect the presence of insects in lumber or structure? You will find answers to these questions in our article. RMNT will also talk about methods of combating insects that have infested the house or furniture.
Tree pests
The most terrible scourge of wood is termite, bark beetle and shashel (woodworm). Wood beetles act quickly and render wood unusable in 2-3 seasons. Termite colony destroys rafter system for 1-2 seasons. It is precisely because of the speed of movement and omnivorousness tree beetles can be “infectious,” that is, they can move to clean, uninfected forest and lay larvae.
Shashel or woodworm
This pest is also called the “grinder beetle.” However, it is not the beetle itself that is dangerous (adults do not live long and do not feed on anything), but its larva. Shashel larvae have a loose structure and developed jaws, with which they grind wood fibers, using nutrients from them.
Bark beetle
This beetle also feeds on oxidized wood - the most “delicious” areas for it are where the bark adjoins the clean fibers.
Termite or white ant
Insects live in large colonies with excellent organization. Species diversity These insects are affected - about 3000 species. Distinctive feature termites are that they move hidden, making passages underground or in the body of wood. Therefore, the termite mound, built in wooden structure, seemingly invisible.
How to identify tree infestation
Lumber affected by insects has characteristic differences:
- visible remains of tunnels under the bark of the wane - bark beetle;
- abnormal lightness of the board, holes Ø 2-5 mm on the surface, while the board appears intact, there are no moves - termite or shashel;
- wood flour (dust), sometimes black-brown in color - all insects.
Wood affected by pests is “not treated”, because insects always strive to capture the largest space and are distributed throughout the entire element or structure, as long as their number is sufficient. If signs of a beetle are detected, you should refuse to purchase the material. If the beetle is found in existing stocks, the material should be rejected and the infested products should be burned.
Presence of larvae in current design can be determined by ear - they make a characteristic grinding or tapping sound as they bite into the wood. In the old days, this sound was called the “death clock”, because practically nothing was known about the possibility of fighting.
Pest control methods
All methods of countering wood insects can be divided into preventive and operational.
Preventive action
This category includes actions for pre-processing lumber, i.e. before it enters the composition building structure. These methods prevent the formation of fungus and make the wood unsuitable for insects.
On-site antiseptic treatment. The simplest, cheapest and at the same time the weakest method of protection. Usually the composition is simply applied to the surface of the wood at the place of storage or immediately before use. For ease of use you have to “pay” with a shallow penetration depth - up to 1 mm. Moreover, any antiseptic has a validity period, usually from 1 to 5 years. After 5 years, any antiseptic is guaranteed to be neutralized and the structure requires re-treatment.
Heat treatment. This method involves heating in sealed heat chambers. In this case, the products are heated to 140 °C, but the lack of oxygen prevents the wood from igniting. The body of the tree is disinfected and the nutrients for insects (sugar, starch) disintegrate; they are no longer “interested” in such a tree. Calcination gives a series interesting benefits- evaporation excess moisture compacts the material and it becomes harder, and the surface is slightly charred - up to 1 micron (0.1 mm). Firing costs 40 to 50% of the price of wood.
Autoclave. Most effective method disinfection and antiseptic treatment of wood - autoclave impregnation. It is used when processing the most valuable products - laminated veneer lumber and laminated laminated beams. The product is placed in a sealed container filled with an antiseptic, into which pressure is then applied to 100 atm. Under pressure, the substance penetrates into the structure of the fibers, and they become completely “inedible” (unsuitable) for insects and fungi. Autoclave impregnation will increase the cost of the product by 50-80% (depending on the substance).
Operational measures
These methods are used in emergency cases - when the beetle has already infested an existing structure. These measures do not give a 100% effect; rather, we are talking about 50% of cases when the development (reproduction) of insects can be stopped. If it is not possible to replace an element, then both old “old-fashioned” and modern technological methods will come to the rescue.
Injection
The most labor-intensive, but quite effective way to combat larvae. To implement it, you will need a basic chemical - a solution of sodium fluoride or sodium fluoride, which can be purchased at a fertilizer store. The method is applicable if inlets are available.
Operating procedure:
- Prepare a solution of sodium fluoride - 250 ml of concentrate per 3 liters of water.
- Clean and blow out the inlet openings with a syringe.
- Prepare a paste of bread and concentrate.
- Using a syringe, inject the solution into the larvae's passage.
- Seal the hole with “putty” made from poisoned bread, if possible, so that the solution remains inside.
Injection will remove wood flour from the passage. The vapors of the solution and the soaked walls of the passage will force the larva to look for an urgent (during the day) exit and it will try to crawl back along the familiar passage. To get out, she will need to chew through the cork of the poisoned bread. All. It looks like a fairy tale or a comic book, but the method was invented and made public by a summer resident biologist.
Tapping
If the shawl or bark beetle is infested in the floor or wooden wall, a simple method such as tapping will help. It is quite effective, especially if visible surface no entry holes. It is better to tap a plane or structure through a block so as not to leave marks from a mallet or hammer. The harder and more often you work on the block, the better the effect will be.
The larvae of shashel, bark beetle and termite consist of 85% moisture, have a loose structure and are not adapted to vibration. The water, vibrating from the impact in their soft shell, simply tears them apart, leaving only mucus. Practice has shown that where the larvae die, new insects do not appear.
Microwave processing
The moisture that makes up the larvae contains processed nutrients, in particular protein, which coagulates when heated to 56 °C. In other words, if you heat the structure to just 58-60 °C, any larvae will die, because the protein in them will simply coagulate. Heat the structure traditional methods is not possible, but modern technology makes it possible to do this using microwaves, which are used in the familiar household microwave oven.
To implement the method, you will need a working microwave oven, which will be irrevocably converted into a unit for combating shashel. Considering the method is 100% effective and harmless, this is a small price to pay.
Operating procedure:
- Trim side wall Microwave oven, opposite the magnetron (usually it is located on the wall with the control panel).
- Determine by ear and mark with a marker the location of the larvae.
- Install the device, pointing the open part (socket) to the site of the larva lesion. The gap between the socket and the surface of the wood is 20-30 mm. The device must be connected in an adjacent room.
Attention! Invisible microwaves cause any protein to coagulate, including the eye protein. Being in the same room as a working device is extremely dangerous. Staying in the next room is absolutely safe.
- Set the timer for 20 minutes and go into the next room to connect the device.
- Plug in the device and wait 20 minutes.
- After the shutdown timer has triggered, move the device to the next prevention point.
The most effective method of continuous prevention will be wave treatment of the entire structure.
Fungus and rot are also dangerous, but their action requires a lot of time and appropriate conditions (heat, dampness, stagnant air). Therefore, natural defects develop much more slowly and it is possible to stop them in time.

Wooden log houses made of rounded logs or timber are at the peak of popularity today. And, building a dacha or Vacation home, more and more people prefer wooden buildings. These houses are warm, eco-friendly and practical. In addition, every home has wooden furniture, which makes the interior cozy and has a long service life.
But not everyone is a fan wooden houses and beautiful wooden furniture are aware of the danger that may await them. We will talk about the shashel - a beetle that can not only lead to damage to furniture, but also to significant damage to the house, even destruction.
Shashel: general description of the pest, damage caused
Shashel (wood borer, grinder) settles in wood and makes through passages in it. As a result, over time the tree simply turns into dust. Moreover, it is not the adult individuals that pose the danger, but the shashel larvae. The larva first gnaws through the wood, penetrating inside. In this field, holes are clearly visible on the surface. Having had enough, the larva begins its journey back to the surface, gnawing through the passage. At the same time, it leaves a protective upper layer approximately 1 mm. Now the larva returns deep again and prepares for pupation and degeneration into a beetle.
The question arises, how is this small insect may eat such an inappropriate product. Digestive system shashel is designed in such a way that cellulose is broken down into smaller particles that are easily digestible. And the enzymes of the digestive tract make it possible to digest such coarse fibers that even more highly organized animals cannot cope with.
Life cycle shashel from several months to several years, it depends on the species characteristics. Damage to wood by shashel occurs very quickly; within a year, the results of its vigorous activity will not be hidden. One larva per day builds a tunnel with a length of 15-30 mm, and given that some species can remain in the larval state for several years, this figure will fit into kilometers. At the same time, the larva grows intensively and the holes it gnaws become larger.
Another sign that a shashel has started will be wood dust under wooden products. Woodworms prefer pine, but they will not neglect other types of wood.
There are 2 types of shashel: furniture and house. Both species pose dangers to wood products. Adults can continue to live in the passages they have gnawed, but they do not feed on wood. You can tell that there is a shashel in the house by its characteristic sounds. During mating, they hit their heads on the surface of the wood, resulting in a sound reminiscent of a ticking clock. Although the location of the grinder is easy to find, getting rid of it is a real problem. Moreover, when you find adult beetles in the house, this means that the grinder has settled in your home a long time ago and has already managed to do a fair amount of mischief. Adult beetles are brown or black in color. Length from 2 to 9 mm.
Grinders are very loving. The pheromones released by the male can attract many females located at a considerable distance. One clutch of a female can reach 200-300 eggs at a time. She lays eggs in the pores, cracks and blockages of wood. After 2-3 weeks, the larvae hatch from the eggs and immediately begin to wear away the wood. The adult shawl beetle does not feed at all; its vital activity is ensured thanks to the nutritional reserves accumulated during the larval period. The main goal of an adult beetle is active reproduction, which is what it actually does.
Shashel can also chew through anything that contains cellulose: cardboard, plywood, books, etc. There are cases where shashel damaged even dry plaster.
Shashel is widespread; it can penetrate into absolutely any home from the outside. The sanitary condition of the home and other provoking factors for other insects do not play any role. It is important for these pests that there is food in the house, and the only food for them is wood.
Purchasing timber for construction work, carefully inspect the material. If at least one hole is found, it is better to refuse the purchase and place an order elsewhere.
Additional precautions.
- At least once a year, conduct a thorough inspection of all wood surfaces.
- If a shashel is detected, action must be taken immediately.
- Favorable conditions for propagation of shashel - high humidity, so make sure there is no dampness in the room.
- During construction, only new wood that is not affected by pests and cleared of bark should be used. There is no need to skimp on boards, since the appearance of the shashel will cost much more.
- If wooden elements affected by shashel are replaced with new ones, then old wood must be burned, excluding the relocation of larvae.
Ways to get rid of shashel, independent methods.
The fight against shawl that has taken a fancy to your home begins with searching for places where the larvae are located. Carefully check everything wooden in the house: floors, furniture, walls. Do not ignore upholstered furniture; the parts inside are made of solid timber and may well become a haven for these pests. It happens that you have to disassemble furniture to determine where the pest is based. If a beam is damaged by a grinder, then after a few years it will remain in dust.
If shashel is found on furniture or on trees in the garden, it is necessary to treat it with fluoride and sodium fluoride. These preparations are sold in specialized stores for gardeners. The drug is diluted at the rate of 250 grams per bucket. The drug is being poured hot water. Affected trees are treated with a spray bottle, and to treat furniture, soak a rag in the solution and wipe everything well. All furniture needs to be treated, even those that have not been damaged.
In the fight against the grinder, a mixture of turpentine (1 l), wax (50 g), creolin (30 g) and paraffin (50 g) can be useful. Furniture and trees are treated with this solution. The solution must be applied to trees while heated using a brush. It is worth noting that using this method can be hazardous to health.
You can also prepare a solution based on gasoline and Vaseline. You need to mix Vaseline oil (liter), melted laundry soap(2 pieces), gasoline (liter), kerosene (liter), naphthalene (100 grams). Furniture is treated with a sponge soaked in a solution, and trees with a brush. After this, cover all the passages with melted paraffin. After a week, the procedure will need to be repeated. Keep in mind that a certain number of larvae are retained when using this method. Therefore, the procedure will have to be repeated periodically every six months to a year.
There are many industrial insecticides that are designed to combat shawl. Both young wood and already damaged old wood are impregnated with these preparations. The most popular drugs in this area are: “Anti-bug”, “Drevotox”, “Antishashelin”, “Empire 20”. But these methods have not proven their effectiveness.
It is no secret that it is better to predict and prevent a problem than to struggle with the consequences of a disaster for a long time and often unsuccessfully. Therefore, preventive protection of wood from damage by shashel is something that should not be neglected. Preventive protection consists of treating timber, beams, boards and other wooden elements special compounds, which are insecticides and antiseptics. Most often, these are organic solvents that are used for preventive purposes and for additional protection.
Professional methods of fighting cabbage: fumigation with phosphine and microwave disinsection
Considering the scale of damage that shashel can cause, it is better not to indulge in experiments, but to entrust the solution to the problem to specialists. Moreover, this problem can arise not only in the home, but also in production, damaging products. Only professional treatment can get rid of shashel with a 100% guarantee.
Treatment of shashel using the fumigation method is an unsafe procedure in the hands of non-professionals, but very effective. Phosphine is a dangerous gas and should only be handled by specialists. All manipulations are carried out in special protective suits. Belongs to the first hazard class. It must be said that the procedure is not cheap, and if you are offered fumigation for little money, then you should not believe it. Most likely, the room will simply be treated with dry fog, and the problem will soon reappear.
The main advantages of phosphine fumigation:
- A high degree of permeability makes it possible to infect insects located even in deep layers of wood.
- Phosphine has a high degree of toxicity, so it can be used not only against insects, but also for rodent control.
- The gas, penetrating the body of an animal or insect, affects all systems and organs, leaving no chance of survival.
In the fight against shawl by fumigation, the following drugs are used: magtoxin and phostoxin.
Magtoxin is a preparation based on magnesium phosphide, ammonium carbamate and paraffins. When exposed to air, magtoxin releases hydrogen phosphide, which has high insecticidal activity. Magtoxin decomposes quickly almost completely, and the residual dust does not contain metal phosphide. This cannot be said about other drugs of the phosphide group.
Fumigation with magtoxin is intended for warehouses and storage facilities that occupy large areas. The fumigation time depends on the area of the room and its gas permeability. No traces remain on the treated surface. Through ventilation after such treatment should last 3-6 hours. If safety precautions are followed, Magtoxin is completely safe for specialists working with it.
Phostoxin is a fumigant with a high content of aluminum phosphide. Gas can penetrate under sealed packages. Since the gas interacts with copper, silver and gold, they must be protected during processing. Used for processing warehouses and storage facilities.
Microwave method (MW)- This is a way to get rid of shashel in residential premises. The microwave emitter is offline installation carrying out disinfestation of premises. Ideal for fighting insects, including shawl, in everyday life. Of course, you can purchase such a device and carry out pest control of premises on your own, but there are a number of nuances that can be missed without special knowledge.
- There are many types of shashel, each with its own characteristics. For example, each type has its own depth of penetration into wood. The heating temperature of the room depends on this, which the specialist will select optimally.
- Heating the entire room is impractical and costly. Professionals know exactly where and with what power to warm up.
- Additionally, equipment will be required to identify foci of the spread of shashel.
- You need to work taking into account the heat transfer coefficient of the material, so you will need a laser pyrometer.
- It is necessary to strictly follow safety precautions when working with equipment.
- To prevent the wiring from catching fire and communications from being damaged, heating should be carried out at a certain angle.
- The equipment is expensive and its purchase will be impractical. It will be cheaper to invite specialists and solve the problem once.
Microwave rays, affecting insects, completely destroy them. At the same time, there is no negative influence They do not affect wood. The main difference between microwave and chemical treatment is the local effect on the specific area being treated. The room temperature does not increase during microwave operation. By affecting a specific area, microwave rays provoke vibration of water molecules, which leads to heating of the wood to the required 56 C°. This temperature is sufficient to completely destroy the eggs, larvae and adults of the shawl. The equipment is completely safe for others during the treatment of household evacuation and household appliances not required. Today microwave is the most effective method getting rid of shashel in residential premises.
Chashel is a beetle that attacks wood. Having appeared in the house, he most often settles in wooden walls, foundations, beams, and can sometimes be found in furniture and books. The most preferable wood for it is wood whose moisture content is at least 14%. But the real pests are not the adults, but the larvae. They gnaw holes in trees and fill them with their excrement. After some time, they spill out onto the floor and look like wood dust.
Chashel is a well-known enemy of wood, which is very difficult to get rid of.
Characteristic
In Russia, two types of shashel are most often found: house and furniture. And yet each of them poses a serious danger to home furniture and wooden house structures. The appearance of this pest will be indicated by a special sound, similar to the ticking of a clock. Insects reproduce it during the mating period by hitting their heads on wood.
On a note! It is easy to identify the nest of pests by this sound, but at the same time, the appearance of adult beetles indicates that their colony is quite numerous and the voracious larvae have already ruined many wooden elements.
But in order to fully gain confidence that it is the shashel in your house, it is advisable to know what it looks like. The body of an adult insect is brown, cylindrical, convex, and elongated.
Development
Development in the egg takes from one to four weeks, after which the larva emerges from it. She molts periodically and at the end of the last phase of development, her body length is about 4 mm, width - 2-2.3 mm.
The shawl larva begins to spoil wood from the moment it emerges from the egg. The starting point is the place where the egg was attached to the wooden surface. Gradually the larva moves deeper, leaving behind narrow passages.
Having satiated, the young shashel goes to the surface and at the same time leaves behind a protective layer, the thickness of which is about 1 mm. Depending on the species, the lifespan of the larvae of these beetles can vary from two to three months to several years.
After some time, the larva goes deep into the wood, where it pupates, and then an adult appears. In an adult shashel, dotted grooves are clearly visible on the elytra.
Methods of disposal
Before getting rid of shashel, you should identify its habitat. To do this you need to inspect:
- all wooden furniture;
- floor coverings;
- wood parts of the foundation;
- beams and partitions.
Upholstered furniture in in this case is no exception. Shashel may fall in love wooden frames and other parts made from solid timber. For this reason, the inspection should be carried out carefully; in some cases, it would be useful to disassemble all the chairs and sofas.
Folk remedies
First, we suggest you find out how to deal with shashel folk remedies.
- The first mixture is prepared as follows. 10 liters hot or good warm water add 250 g of sodium fluoride solution. Mix everything thoroughly, pour it into a household spray bottle and process everything wooden surfaces and objects in the house.
- The second composition is based on lime turpentine. For 10 liters of turpentine add 300 g of creolin, 500 g of wax and 500 g of paraffin. The composition must be mixed until a homogeneous mass is obtained and the wood must be lubricated with it.
- The third mixture consists of 3 liters of turpentine and 1 liter of kerosene. Mix the ingredients and use them to process wooden objects.
Important! Turpentine and kerosene can ignite quickly, so when working with them, you should follow safety rules. And to prevent their vapors from leading to poisoning, use individual means protection!
Insecticidal and antiseptic preparations
The destruction of shashel can be carried out using industrial means described below.
"Anti-bug" is an antiseptic that works well against all pests that attack wooden surfaces. Moreover, this remedy acts on both adult individuals and their larvae. "Antizhuk" can be used in the future for prevention. It is not highly toxic, and when used, maintains the integrity of decorative coatings.
"Antishashelin"— this product is intended for the destruction of all types of woodworms, including shashel. This drug is an organic solvent containing a solution of silicones. “Antishashelin” is characterized by high penetrating ability, and therefore it can be used to impregnate both young and old wood. It is used for processing furniture, floor coverings, including parquet, as well as antiques and various wooden building elements.
On a note! Antishashelin is most effective when it is injected into holes made by insects using a syringe!
"Empire 20"- one more thing is enough effective remedy from shashel. It is easy to use and at the same time is considered a reliable ally in the fight against domestic insects, even with a significant number of their colonies. This insecticide is characterized by low toxicity to humans.
Advice! Whatever product you choose, remember that to get a positive result, you must carefully process it. In order for the product to be absorbed into the wood deeply enough, it must be applied 2-3 times with an interval of 2-3 days!
And in order not to rack your brains over the question of how to deal with shashel in a wooden house, it is enough to remember the rules for using elements and structures made of wood. First of all, at least once a year, inspect all wooden parts of the structure and, if found, the slightest damage process them immediately protective coatings. Do not allow humidity to increase, as this is often the cause of the appearance of shashel. When building a house, pay attention to the quality of the material: the wood must be new and cleared of bark.
It's small black insect most often starts in wooden houses, in wooden beams, floors and even wooden furniture. A characteristic indicator of damage to wood by this insect are small holes that the shawl gnaws.
Several types of beetles live in Russia: wood beetles and furniture beetles; they can be found not only in wood, but also in books, leather goods. Chashel often appears in cereals. It has an elongated black or dark brown body with a dense shell, which is clearly divided into the head and abdomen.
On the head there are long, slightly curled, indirect antennae. The size of the bug does not exceed 5 mm, which allows it to remain unnoticed for many months, or even years.
Important: the beetle does not pose a danger to human life and health. The only thing it affects is property.
Reasons for the appearance of shashel in cereals
Important: If you do not notice the appearance of beetles in time, they can move to other rooms where there is food.
- importation from outside: purchase of affected cereals (especially if the sale is carried out by weight);
- unsuitable bags and containers for storage: they need to be washed regularly and doused with boiling water; the most suitable for storing bulk products are glass jars with tight-fitting lids and plastic containers;
- too much high humidity in room;
- high or low temperature in the apartment, temperature changes;
- purchasing large quantities of cereals at once. Housewives are advised to buy no more than two packs of cereals, pasta, cookies and other flour products.
Advice: buy cereals in transparent bags or with transparent “windows” so that you can see the pest. Pay attention to the folds in the packages, carefully review each package purchased in the store. If you once noticed packaged beetles in a store, exclude the products of this company from your purchases and inform the store administrator.
Methods for removing beetles
Insects even get into food products that they do not eat, so even they are then not ready for consumption. How to raise shashel in cereals in the kitchen?
Fighting kitchen pests sometimes takes weeks and months for many housewives. There is no need to be lazy about washing all the furniture and processing it.
In rare cases, you can save yourself from beetles using folk remedies: garlic, bay leaf and vinegar. If the shashel has spread throughout the kitchen, it is necessary to resort to more serious measures.
Expert answer:
Hello Polina! Shashel (wood borer) is a small bug that in itself is not dangerous. The real pests are larvae that eat holes in trees, as a result of which the tree soon turns into dust.
How to deal with shashel?
In our latitudes, two varieties of shashel are common: the house grinder and the furniture grinder. Both bugs pose a danger to all wooden products. Adults often live in gnawed tunnels, but they do not feed on wood. The main purpose of the borer beetle is to reproduce.
It is quite easy to identify the grinder, because during the mating season they hit their head against the wall of the wood, which creates a sound similar to the ticking of a clock. It is much more difficult to get rid of shashel. The discovery of adult individuals indicates that the shashel has been living in your home for quite some time.
Where to begin?
So, as mentioned above, it is not easy to remove this pest. The fight against it should begin by searching for the habitat of the pest larvae. Inspect everything carefully wooden crafts: walls, furniture, floors.
Is no exception cushioned furniture, since its internal parts are made of solid beams, and therefore suitable to become a home for shashel. Therefore, sometimes you have to disassemble chairs, a bed, a sofa in order to find the beetle’s home.
If you are undergoing construction and you purchase timber for construction, inspect it carefully. If there are holes, refuse such a purchase, since most likely all the bars are contaminated. Just a few years and all that will be left of such timber is dust.
Recipes for poisons against shashel wood borer
If shashel is found in furniture or on fruit trees, it is imperative to treat the wood with sodium fluoride or fluoride. Such chemicals can be purchased at any gardening store.
Dilute 250 g of product in 12 liters hot water, stir and cool the water. Pour the solution into a spray bottle and process garden trees. If the shashel lives in furniture, you need to moisten a rag in this solution and wipe all the furniture, even those that are not infected.
A mixture of paraffin, creolin, turpentine and wax will help kill the shashel. To prepare the product, use 30 g of creolin, 50 g of paraffin, 1 liter of turpentine and 50 g of wax. After mixing all the components, treat the furniture with the resulting mixture. For fruit and berry trees You should use a heated solution and apply it with a brush.
A solution of turpentine also helps remove shashel. To prepare it, you should dilute a liter of vaseline oil, two pieces of melted soap, a liter of gasoline, one hundred grams of naphthalene and a liter of kerosene in 3 liters of turpentine. Mix the product well and wipe the furniture with it using a sponge or brush. Now melt the paraffin and seal all the passages with it. Repeat the treatment after a week and lubricate the passages again. If the holes in the wood are small, cover them with regular Vaseline and, if possible, fill the passages with it.
If all your efforts are in vain
Sometimes you can't cope on your own. If the damage to the wood is too extensive, entrust the destruction of the pest to professionals. There are companies that offer to rid you of shashel using microwave irradiation. This method especially effective if affected wooden houses or wood trim indoors.
Microwave equipment performs well. The irradiator is easy to use and reliable. With its help, you can process structures up to 25 cm thick. As a result, the shashel will die even in the deepest layers of the tree.
The advantage of this method is that with the help of microwave equipment it becomes possible to destroy wood shashel under layers of paint, clay and varnish. This method of processing a wooden structure does not pose any danger, since the irradiation is carried out using remote control. Irradiation does not leave any toxic traces, and disinfestation can be carried out at any time of the year.
Reliable means to combat shashel
You can treat wood against pest beetles using industrial insecticides. Below is a list of the most effective ones.
- Antibug. This antiseptic is created to destroy pests that disfigure wooden surfaces. The advantage is that the insecticide destroys not only adults, but also larvae. This product is also used to prevent wood borers from infecting it. You can use Antizhuk for both external and interior works. The chemical won't hurt decorative coating material and it is non-toxic.
- Antishashelin. The product is intended for the destruction of woodworms. Used to impregnate old or young wood. Antishashelin is a solution of silicones in an organic solvent with high penetrating ability.
- Woodtox. One of the most effective insecticides. Items soaked in this chemical will be toxic to shashel for six months. Applicable all year round, but from June to January the effectiveness of the product is higher. Wood tox is injected into the cracks and passages made by the shashel using a syringe.
Using one of the above-mentioned remedies, you will get rid of the pest bug forever.
