Insecticidal remedy for sheshelya. Methods for processing wood from insects - the fight against wood-boring beetles (shashels). Insecticide and antiseptic preparations

Question: Can you tell us more about the methods of treating wood from insects, such as carpenter beetles (shashels). How to deal with them, what means are used for this?

Building your own house or cottage is unthinkable without the use of building materials from wood. Made from wood wooden houses, floors, windows, window sills, doors, rafters, floor beams, etc.

But sometimes, even when choosing very good quality wood, ignoring the additional protective treatment from harmful insects leads to premature destruction of wood. If a characteristic sharpening sound appears in the house and small chips (wood flour) pour from wooden products and structures, this means that they have settled in the wood carpenter beetles and its larvae. The people call these insects - shashel(black brownie with a mustache).

Carpenter beetle (shashel) - how to get rid of?

This beetle is an insect 8-20 mm in size, brown or black, photo 1. Lifespan adult is 3…7 years. The wood borer mostly loves pine wood, in a dry state, although they do not refuse other types of wood. The main part of the tree they infect is the sapwood.

The wood borer is not as dangerous as its larvae, which hatch from eggs that it lays in pores, blockages and cracks in wood. One carpenter beetle is able to lay up to 200…300 eggs at a time, and after 2…3 weeks, larvae hatch from them, immediately starting to grind wood.

The life span of the larva is 5–17 years, and during their lifetime they are able to make “tunnels” in wood with a total length of up to 40 km. The larva is capable of laying a mini-tunnel 15–30 mm long in wood in a day, and at the same time it can grow intensively - its weight can double in a day.

The danger of the larvae lies in the fact that from the moment they begin their lives, they long time are inside the wood, not showing out, and only when the larvae turn into beetles, they tend to go out, as evidenced by small round holes, photo 2. Therefore, as a rule, when the presence of this beetle is detected, its larvae have already done a large amount of work to destroy the wood.

Examples of the destruction of wood by a wood borer (shashel)

There are many methods to combat woodworm. Conventionally, they can be divided into:

• preventive ways to protect "healthy" wood from possible pest penetration;
• ways to deal with insects that have already hit the wood.

Preventive protection consists in processing beams, bars, boards and other wood elements with the help of special solutions and antiseptics, even before the start of construction, photo 3.

On modern construction market very big choice preventive protective equipment various manufacturers. Here are some of them:

Belinka - organic solvent. If it is necessary to process for the purpose of prevention and additional protection, apply Belinka Belocid, and if the wood is already affected - then you should apply Belinka Fentin, photo 4;

Antishashelin - the drug is intended for the destruction of wood-boring beetles, shashels and their larvae. Effective when injected directly into holes made by insects with a syringe;

antiseptic Lignofix absolutely safe for humans, does not emit toxic substances. The drug is only dangerous for chitin-containing insects, disrupting the physiological processes in their body that are responsible for the development and reproduction of insects. This drug does not decompose over time, and retains its properties for 10 years.

Also popular antiseptics from manufacturers such as Pinotex, Olimp, BioColor, Aquatex and etc., photo 4.

Advice: Attention should be paid to the purpose of the selected antiseptic, because not all antiseptics are able to destroy or prevent the penetration of woodworms. To obtain a high effect from the treatment of wood with antiseptics, it should be covered in 2 ... 3 layers with an interval of 2 ... 3 days. With full observance of the antiseptic application technology, the wood will be impregnated by 2 ... 3 mm. In practice, antiseptics are effective as a prophylactic, i. when new, uninfected wood is processed.

Antiseptic treatment of wood affected by beetles can only help for small wood products, provided that the beetles have recently started.

Methods for treating wood to protect against insects

Ways to protect wood from woodworms that already live in the breed include the following:

• dry steam method;
• insecticides: substances of residual and instant action;
• fumigation method;
• fogation (fumigation) of wood;
• douching method;
• method of processing by microwave beams;
• folk remedies.

Dry steam method

The essence of the dry steam method is to gradually heat the wood to 80 ... 90 ° C with the help of dry steam and thereby dry the material. At such a temperature and lack of sufficient humidity, insects and its larvae die.

Advantages of the method

• does not damage the wood structure;
• does not spoil the appearance;
• in addition to the woodworm, it can destroy the fungus;
• does not leave an unpleasant odor;
• can be used for an already assembled or built structure;
• steam penetrates into hard-to-reach places;
• steam treatment lasts approximately 6 ... 8 hours;
• relatively inexpensive way (compared to other methods)

The disadvantages of the method

• limited use (mainly used for wood products in attics and attics);
• fire hazardous method - it is necessary to take out fusible and easily flammable materials and products.

Insecticides

Insecticides are the same antiseptics, only they can still be sold in the form of aerosols and emulsions.

Subdivided into:

1. residual substances applied to the affected and (or) healthy wood surface. The substance also penetrates to a shallow depth of wood, its smell attracts the beetle to itself, and they crawl out to the surface, where they die. The preparations are low-toxic, which allows entering the room within a few minutes after treatment. Has no smell.
2. instant action substances lead to the rapid death of insects. You can return to the treated premises after 3-4 hours of treatment.

Fumigation

The fumigation method is a treatment with hydrogen phosphorous PH 3 (phosphine) in the form of a gas interior spaces. A feature of phosphine is its high permeability to wood. The second feature of phosphine is that it is a chemically unstable gas; over time, it completely decomposes, which means that you do not have to breathe this gas after processing.

Advantages of fumigation

• penetrates into all cracks and hard-to-reach places;
• no smell.

After gas treatment of the premises, a long and high-quality ventilation of the premises (1 ... 2 days) should be carried out. For fumigation, special equipment is used - a hot or cold fog generator, photo 5.

Fogation (fumigation) of wood

Produced using special equipment- aerosol mist generator. Chemicals with the help of equipment turns into steam, which treats the surface of the wood. The disadvantage of this method is the surface effect, ie. Chemical substance does not penetrate deep into the wood.

Douching method

The method of protection against woodworms is based on the direct injection of antiseptic agents into the insect passages made with a syringe. The method is effective only at the initial stage of wood damage, when there are relatively few insects.

In wooden products and structures that need to be “cured”, holes are drilled in inconspicuous places with a diameter of 7 ... 9 mm in increments of 50 ... 100 mm. Then, an insecticide is injected into the holes made with a syringe, after which the holes are closed or smeared. This procedure must be repeated 2 ... 3 more times, as the substance is impregnated from the hole into the wood.

If the dwelling is being processed at the time of processing, you should leave for 2 ... 3 days. Douching is a very laborious method, but with careful work it is crowned with success.

The method of destroying insects using microwaves is that when exposed to such waves, the wood is heated to a temperature at which the larvae and beetles die. The advantage of this method is that it can be used in hard-to-reach places, does not affect a person and does not change the structure of the material.

How to kill insects with microwaves

The disadvantages of this method are high labor intensity for large volumes, as well as the need for special (not cheap) equipment.

Folk ways to deal with woodworms

There is also a lot folk ways woodworm control. Here are a few homemade compositions for wood processing.

Blend #1:

It is necessary to prepare by thoroughly mixing a mixture of the following components:

• sodium fluoride solution 250 g;
• water (warm or hot) - 10 liters.

Composition No. 2:

• paraffin - 5 parts;
• wax - 5 parts;
• creolin 3 parts;
• lime turpentine - 100 parts;

Stir thoroughly until a homogeneous mixture is obtained and then should be applied to the surface of the wood.

Blend #3:

• kerosene - 1 part;
• turpentine - 3 parts.

Untested method:

• There is also an opinion that woodworms and their larvae do not like vibration. In practice, the authors of the article did not check this, but we will cite the experience of others. With the help of a small bar and a hammer, tap on the affected wood. From vibration, the larvae die (as the people say).

A few tips for the proper operation of structures and elements made of wood

1. At least once every one or two years, it is necessary to carefully inspect the surface of the wood for damage, including from insects.
2. At the slightest damage, it is necessary to immediately treat with protective coatings.
3. Increased humidity of the room and wood - good conditions for insect development. Therefore, it is necessary to strive to keep the premises dry.
4. Usually the fight against woodworm is very difficult, time-consuming and requires patience. Since these beetles reproduce very quickly, wood processing should be carried out at least 2 ... 3 times with an interval of approximately 2 ... 3 weeks. It is recommended to carry out processing in the spring - summer, since eggs are laid and hatched during this period.
5. During construction, new, uncharged wood should be used. It is not recommended to save on wood processing products, since when a wood borer appears, you will have to spend ten times more money.
6. In new construction, it is imperative to use bark-free wood. Not bad if wooden structures are built from planed lumber.
7. During the reconstruction of buildings, the contaminated wood of the structures should be replaced. Dismantled structures should be disposed of (burned or removed from the site).
8. You should carefully follow the instructions for the use of a particular method and means.
9. Most effective way woodworm control is fumigation, but this method should be performed by a professional specialist.

We hope that our advice will help you prevent the appearance of harmful insects, and if they appear, effectively get rid (remove) them from the wood.

The arrangement of floors in houses allows infection with shashel, which often happens. Logs, subfloor - boards or parquet can be infected. It should be noted that Italian parquet is eaten in the same way. Again, woodworm colonization could occur both at the stage of board production and during operation. Poor-quality or old (after all, it is required every 3-5 years) treatment of wood with insect repellents. Again, dampness from the underground space, so a mistake during construction will attract both mold and woodworm. Which will make life in the house simply impossible.

But you should not be immediately afraid, having Shashel microwave equipment. No, this problem is solved quickly and reliably. No need to disassemble the floor, change the logs,

rough boards and parquet, especially since this is an extremely expensive pleasure, which entails no small repair. In cases where the top layer of the floor device is not infected and it is required to process logs or draft boards, the exterminator can easily cope with this problem. After all, the peculiarity of the microwave field lies precisely in its high penetrating power and selectivity in the process. Directing the screen to the infected area, simply placing the equipment on the floor, woodworm larvae will be destroyed throughout the entire depth of the floor device. Again, the wood will be dried, removing a favorable environment for mold or the Mustache beetle, if it was the place to be.

In cases where the base is a concrete monolith through a heater and only on top we have wood in the form of parquet, the problem is solved in exactly the same way, because polystyrene foam is radio-transparent materials and will not interfere with us.

And the same process happens for floors where possible wooden beams. Shashel is destroyed quickly and without disassembly and costly repairs.

Most of the furniture is made from wood. Which also makes it susceptible to woodworm infestation. Here they encounter a furniture grinder or a watchmaker beetle. English title Deathwatch beetle is given to him for the characteristic sound made by a gnawing larva, the tick of a clock that measures the time to death. The furniture grinder loves dry wood, leaves very small holes, and its larva has a very long development period, up to 15 years. If signs of a furniture grinder are found, it is not worth pulling with destruction, because. infection is easily spread to others wooden items in your house. It can be, like other furniture and door, window frames and parquet. The furniture grinder eats thoroughly from the wood, only dust remains.

Infection with a grinder beetle can be both natural and acquired immediately with furniture. Often furniture from the Middle Kingdom sins with this, so wood pests come to us that are not at all characteristic of our latitudes, but in warm room they don't care anymore. So with exotic and beautiful wood, more are purchased, which can pretty much ruin and even simply destroy furniture. There have been cases of existing infection in furniture facades for kitchen. Italian chipboard, for all its seemingly unattractiveness for furniture grinders, was infected with woodworm.

For such cases, Shashel.net has equipment for restorers. Lightweight and reduced emitter allows disinfestation even in the most difficult cases. With such equipment it is possible to process antiques, icons and so on. A careful and accurately dosed microwave field will act exactly on the woodworm larvae, without disturbing the structure of the wood and without destroying antiques. Nails or any other metal furniture fittings do not affect the processing process and the equipment itself. In this way, the furniture will be saved and the grinder beetle will be destroyed quickly.

Shashel in the rafters. Treetop on the roof.

Low-rise private construction has been gaining popularity since the collapse of the USSR and the advent of private property. Every person wants to have own house and be the master of it. And the roof device in houses is often made of a wooden truss system, which is very tasty for shishel. Warm attic space with an abundance of wood make almost ideal conditions for woodworm all year round. And a new negligent owner of the attic may appear - Shashel. It ends sadly: the roof, rafter system over time, they lose strength, bend under their own weight, the tightness is broken, and if this process is not detected and stopped in time, the roof will collapse.

During construction, it is necessary to monitor the quality of the wood used, the treatment with preventive fire-bio-protection, which, by the way, must be repeated every few years, otherwise trouble will not be avoided. Replacing rafters, as well as the entire roof, is an expensive process. Which is better to be warned. If the infection is still detected. Action is required immediately. For such situations, there is microwave equipment that allows you to quickly. A specially designed system allows processing even in the most difficult conditions.

So it offers complete solution to fight woodworms. Equipment designed for self use. Ease and simplicity of management allows you to make the process fast, and most importantly, deadly for the woodworm. Microwave equipment is guaranteed to destroy wood pests even in the most difficult cases. And for wooden houses be always at hand.

Man in modern world it is hard to live in harmony with insects, especially, it is difficult to exist in the same house with a shashel. quickly destroy the log house, because for him it's just food.

The use of pesticides will most likely lead to:

• addiction and resistance to insecticide, it should be noted - any chemical preparation is effective only in the uppermost layers- on the surface of a tree (only a few millimeters).
• Modern GOST, SNiP states that infected areas in a wooden structure must be replaced with a metal "prosthesis".
• There are folk methods, but the most effective was to burn the house until it infected the neighboring ones.

Gassing with checkers, "fogs"- fumigation is an extremely difficult method of disinfestation. Careful preparation of a wooden building is required, qualified specialists who have completed special courses and have supporting documents. This is not a one day process. It is permissible to carry out work only in summer when certain temperatures are reached. There may not be a result, because often the passage behind the larva is littered with wood dust, excrement - the poison cannot penetrate. In addition there is deadly danger for people.

German DIN standard.

Thermal methods have their own difficulties, if disinfection of the whole structure is required, then it is technically almost impossible to create the required temperature, namely 56 ° C.

In the early 90s, microwave technology was developed in the West, which guaranteed complete, safe destruction.

Microwaves can be used to control pests at any time of the year. Radiation exterminates all insects in the thickness of the wood, dries mold, fungus. Wherein no detrimental effect on timber.

An electromagnetic field of ultrahigh frequency is created, in which water instantly raises its temperature, up to turning into steam. Any beetles, larvae, egg laying are simply boiled alive. At a temperature of 55-60 degrees, animal protein coagulates! The death of xylophages is inevitable.

Most temperature changes occur where there are more H2O molecules. Insects contain up to 95% of moisture; under the influence of EM fields, they are guaranteed to die.

Advantages of the equipment:

1. Radiation evenly distributed over the area, deep into the wood.

2. Independent operation with simple, clear control.

3. Non-invasive - no damage.

4. No poisonous residue.

5. Environmental friendly

absolute and proven efficiency under all conditions.

6. Without exception, a controlled process.

7. Metal nails, staples, electrical wiring and so on is not a hindrance.

8. Works are carried out at any temperature.

9. Reliability of equipment, protected emitter from moisture, dust and dirt.

10. The radio transparency of dielectric materials ensures the processing of hidden wood. For example, sewn with plastic, ceramic tiles, drywall or paint, wallpaper. Various heaters are also not a hindrance to equipment.

11. Possibility of disinfestation of books, furniture, icons, antiques.

12. Mobility, convenience of various modifications for any situations.

13. Does not require the relocation of residents or the removal of home appliances.

14. Unconditional Guarantee on emitters and getting rid of shashel.

Silence, comfort, integrity of your wooden house

Shashel is the enemy of wood. Bug small size starts in the beams, wood flooring, window sills, window openings. Prefers wood with a moisture content of at least 14%. The wood borer lays eggs in the conquered territory, after some time larvae are born, which are the main pests.

Appearance description

In our area there are several types of shashel - furniture, brownie. Each of these pests causes significant damage to wooden structures, furniture, even books and leather goods. What a shashel looks like, many people know, but do not realize that this is it:

• elongated body with a strong shell;
• color brown or black;
• the size of the pests is several millimeters;
• on the head are long twisted striped mustaches;
• three pairs of long, fairly powerful limbs.

By itself, the woodworm is harmless, does not pose a danger to life, human well-being. But living with him under the same roof threatens with serious damage to property.

The larva of the shashel is a thick dirty-yellow caterpillar with a well-developed mouth apparatus. It does not leave holes, so it is problematic to see it. But give out the presence of characteristic sounds.

The photo of the shashel is presented below, you can clearly see all the features of the structure of the body, the color scheme.

Features of life

The presence of a shashel in a tree is indicated by a specific sound, similar to the ticking of a clock, chirping. It reproduces during the mating period of beetles. You should look for them on the surface of the wood. Because at the time of mating, woodworms leave their holes.

The sound determines the location of the nest, as well as the degree of infection. The more intense and louder the ticking, the more pests in the house. Another characteristic sound is created by larvae, which, with a special appetite, gnaw wood for days and nights. Minks are filled with excrement, which crumble over time, resembling sawdust, wood dust.

Adult beetles spend most of their lives in the nest, making more and more new moves in different directions. But the main pests are larvae that do not leave their holes at all.

On a note!

Infection of the house occurs during construction, when using material with larvae, shear eggs, in old wooden houses with cracks in the wall, window sills, doorways. And also in new design if attention was not paid to the careful processing of the wooden components.

Larval development

In the egg, the shashel develops from 1 to 4 weeks. The larva of the first stage is a caterpillar. Starts wrecking immediately after birth. It gnaws through numerous moves. Periodically passes molting, gradually increases in size. The larva of the last stage reaches 4 mm.

It is difficult to say how long the shashel beetle lives in the larval phase. According to different information. develops in the conquered territory from 3 to 15 years. At the last stage, it goes deep into the tree, pupates. It comes to the surface already formed by a wood-boring beetle. But after mating, it returns to the tree again to build a nest, lay eggs.

Fighting methods

There are several ways to get rid of shashel. The choice depends on the degree of infection, financial capabilities, personal preferences.

• Insecticide treatment. Antiseptics are used a wide range actions.
• Application folk remedies. Cooking special blend, which blocks the access of oxygen to larvae, adults, causes death.
• exposure to microwaves. Carried out by experts modern equipment. The generator generates microwaves that are directed to the infected wood. It warms up, kills the larvae of the shashel, beetle. The disadvantage of the method is laboriousness and high cost.
• Dry steam treatment. The action is similar to the previous method. Dry steam heats the wood, reduces humidity. Under such conditions, the larvae of the shashel perish, the beetles themselves.
• Fumigation - fogation, fumigation. Hydrogen phosphorous is used, which is able to penetrate into the deep layers of wood, destroy the larvae of the shashel, adult beetles.

Used at home chemical method using insecticidal preparations, folk remedies.

Proven Recipes

If the shashel wound up in wooden board, getting it out of there is problematic. But you can make sure that he either gets out himself, or ends his life in a hole. Initially, you can use folk remedies.

• Boil 10 liters of water, mix hot with 250 g of potassium fluoride. Stir for 5 minutes, pour into a spray bottle. Treat the tree from the shashel. Work should be carried out with rubber gloves.
• In 10 liters of lime turpentine, add 500 g of wax, paraffin, 300 g of creolin. Stir until a homogeneous consistency, process the wood.
• 3 liters of turpentine are mixed with 1 liter of gasoline. With the help of a brush, a tree is processed from a shashel.

A significant disadvantage for all folk methods is an unpleasant pungent odor. It is better to fight the shashel in this way in a non-residential building or from the outside. Wood impregnated with kerosene, gasoline becomes a fire hazard. Therefore, before using the remedy, it is necessary to weigh the pros and cons.

Professional preparations

Wood processing from shashel is made with antiseptics, insecticidal agents.

• Antizhuk. Universal remedy for all wood pests. Destroys adult shashels, larvae at different stages of development. Process carefully once. But to consolidate the effect, it is recommended to re-treat after 14 days. Used for prevention. The remedy for shashel in the house does not have high toxicity, but it is necessary to work with rubber gloves.
• Antishashelin. Destroys all types of woodworms. The composition contains silicones that can penetrate into the deeper layers of the tree, destroy the shashel and its larvae. Used for processing old wood, fresh, furniture, antiques, floors, any wooden structures. Preserves the integrity of the tree, does not spoil the appearance.
• Drevotex. According to customer reviews, one of the most effective drugs. Helps to destroy the shashel, protects against re-infection for six months. It is recommended to process several times during the year, every 3 months. The agent is poured into the passages of the shashel with a syringe. From above close up holes with vaseline, paraffin. For prevention, the procedure should be carried out in the middle of summer and winter. In case of severe damage to the tree, treat the surface with a brush, apply a thick layer of the drug.
• Lignofix. Antiseptic does not contain toxins. After application, it does not lose its properties for 10 years. Destroys chitinous insects. Enters the body, disrupts biological processes, leads to death.

In order not to think about how to quickly and effectively get rid of the shashel, it is necessary to inspect wooden structures twice a year and carry out preventive treatment.

Shashel in the kitchen

Often, housewives are found in flour, croup of small dark-colored bugs, similar to shishel. In the kitchen, the woodworm lives only in wooden structures, not interested in food stocks. This is another type of pest that looks like a shashel.

The fighting methods are extremely simple. Throw away the contents, thoroughly wash the container in which the supplies were stored, carry out general cleaning in lockers. Wash furniture with vinegar solution.

Shashel does not live in cereals. This is a completely different kind of pest. Therefore, it makes no sense to use antiseptics, insecticides in this case.

Among wood pest beetles well known Shashel. Adults communicate with each other with a very loud sound. They can be detected by touching the head of a tree, usually at night, and hearing a sound like someone is sawing something. Adults are reddish to dark brown and lay their eggs in crevices or small holes or pores in untreated (unprotected) wood. Two years may be required for a full cycle of each generation. That's why get rid of from them and completely destroy by conventional means difficult.

Shashel - beetles are mainly in soft wood, including in beams, walls, foundation timber, and some types of furniture. They can even attack books. This wood pest usually found in old wood and partially decaying. Shashel prefer wood that has more than 14% moisture content. Larvae Zhukov fill their holes gnawed in the depths of the tree with excrement, which spills out onto the floor and resembles fine gray-brown wood dust.

Ways to deal with shashel difficult once infection has begun. Prevention is the best way management. Protective measures must be taken at all stages of processing wood, including sawmills, mills and factories for the production of lumber and furniture, and construction firms. Sanitation is the most important aspect prevention. Destroy dead parts of trees (before they become infested) near buildings or near any area where timber is stored. Drying lumber helps get rid of from Zhukov pests, although this does not prevent re-infection. Materials used for the construction of buildings and wooden furniture, must be carefully checked before use to ensure they do not contain wood pest. protection wood from infection - painting or varnishing to seal the pores, cracks and holes where eggs can be laid.

so as not to accidentally bring shashel, inspect furniture and other wooden objects before they enter your home. As fight against shashel you can fumigate objects that show signs of infection beetle. small wooden articles (but not those containing fabrics, skins, or dyes) may be heated in an oven at 50-60°C for 6 hours or placed in a freezer at -17°C for 72 hours. Longer treatment may be required if the tree is thicker than 2 inches.

Ways to deal with shashel:

Remove and replace infected wood structural parts. Destroy infected wood. Where removal is not possible, use liquid insecticides that are labeled for these pests, such as NEOMID 100 Anti-Beetle Biocide. It should only be applied to infested areas. But be sure that you thoroughly impregnated all surfaces, applying 3-4 layers of the composition. And also, using a construction syringe, introduce the Antizhuk composition into all holes bored shashel in wood, to and get rid of from the larvae inside. The penetration depth is enhanced in wet wood, if the moisture is less than 15%, the penetration can only be 1 cm.
Be sure to follow the instructions on the label. Wear appropriate protective clothing and respiratory protection.

For the treatment of extensive wood damage and invasions shashel inside the building, or where treatment of the structural parts of the building is not available, order the fumigation of the entire building. It is offered by many professional operators fight With pest beetles.
