Beetles bark beetles are the main enemies of wooden houses and structures. It is they who become the cause of the violation of the integrity of the structures of the house, which gives people many difficulties. In the fight against their invasion, the main thing is not to waste time, but to take immediate measures. In the article we will talk about how to get rid of bark beetles in a wooden house using folk remedies. And also consider the methods of chemical and technical exposure to insects.
Let's get started!
Residents of apartment buildings have most likely never encountered such a problem as a beetle bark beetle (shashel). Unless those who have wooden country houses. On various forums and Internet resources, you can see photos of bark beetles and the results of their work. In another way, the bark beetle is called a woodworm or grinder. The owners of houses from a bar know very well how much damage this insect can cause to their possessions.
In this article, you will find out who this bark beetle is, how dangerous it is, what prevention methods exist, and how to get rid of it.
Bark beetles do not pose any danger to people, as mosquitoes, flies, bugs or lice. The living environment of these insects is trees and all materials from them. Grinders hide in the bark of a tree, and gnawing through all its layers get to the center. There, the females lay eggs, which become larvae in a week and cause irreparable damage to the wood.
In 24 hours of the bottom, the larva is able to absorb about 10 g of wood.
In winter, the larvae fall asleep, they can withstand air temperatures up to -30 o C. It is interesting that they can stay in this mode for three years. Then they develop into pupae and adult beetles. And, the breeding process goes on as usual.
Adult bark beetles are able to move to neighboring trees, expanding the boundaries of their existence. Wooden structures become victims of woodworms: houses, barns, baths. Wooden houses damaged by bark beetles are destroyed over time, the wood turns into dust. It is unsafe to damage the supporting structures, because in this case, the house may collapse. Woodworms have another negative property, they are carriers of fungal spores, which accompany the formation of mold, and in fact it is very harmful to humans.
Very often, bark beetles are found in the wood stored in warehouses. Therefore, the cases when contaminated material is used in the construction of houses are not alone. To avoid this, it is necessary to adhere to the standards of wood storage.
Before purchasing wooden building materials, conduct a thorough inspection. Small holes and winding paths in the material should alert you.
This is the result of the work of bark beetles.Unfortunately, untreated logs are difficult to inspect as defects are not visible on the bark.
Therefore, experts recommend examining the cuts of logs for damage.
The wood must be dry, since bark beetles feed on tree sap, the more of it in the material, the higher the chance of infection by insects.
When purchasing a house made of wood, first of all inspect it for traces of bark beetles.
It is very likely that the owners are selling their homes precisely because of this.
To protect housing from this plague, be sure to treat wooden houses from bark beetles with antiseptic substances 2-3 times , with a frequency of 7 - 10 days. For this purpose, they use: Antizhuk, Wood Doctor, Ekolan-41, etc. Premises not intended for human habitation are most often treated with recycled machine oil.
These insects are nocturnal, hiding inside solid wood.
In this regard, it is difficult to notice it, but it is possible if you pay attention to such nuances: carefully inspect wooden floors, walls, furniture, etc. Small holes of 1 - 2 mm indicate that there is an infection. Gnawing through the passages, bark beetles leave white or yellow dust. It can be found near baseboards and on the floor.
Night is exactly the time of day when you can hear how the bark beetle "crunches" wood.
These sounds are reminiscent of a clock.
In ancient times, the sound of bark beetles grinding wood was taken for a bad omen. It was believed that some of the inhabitants of the house would die. Nowadays, no one believes in superstition anymore, but there is a rational grain in this sign. After all, damaged wooden structures can collapse at any time, which is fraught with death.
In certain countries, the sound that bark beetles make is still called the "clock of death".
Getting rid of a bark beetle is very difficult, but there are no hopeless situations. Let's consider the most effective ways.
Insecticidal agents, it is quite possible to prepare yourself.
They show great efficiency at the beginning of wood contamination. In order to understand how deeply the tree is struck, you need to take a screwdriver or awl and pierce the wood. When a large number of voids, places of damage by a bark beetle are found, the tool will enter the material like a knife into butter. With minor damage, only a little will enter the tree.
With a slight damage to the material, you can use the procedure to combat the bark beetle in a wooden house in the complex.
To do this, you need to take the wire, push it into the hole to the end and twist it. This will damage the stroke and kill insects. and rotate.Then the surface of the wood and the moves made by the beetles must be filled with a special substance. Treat the top with a sponge or spray bottle.
Pour the composition into the strokes with a syringe. You need to inject the liquid until it completely enters them.
For treatment use the following substances:
Boil the mixture. Add 1 vegetable oil and cook for 1 - 2 minutes. Refrigerate the mixture. Then apply in one of the ways described above.
The holes made by bark beetles are poured with the mixture.
They are also good, but progress, as they say, does not stand still. A syringe cannot be used with this technique, because the liquid must be very hot.
entrance holes with silicone or acrylic sealant. This will help kill those beetles that survived the first stages of the attack.
After a week, the treatment of a wooden house from the bark beetle must be repeated with the substance that was previously used. Then, again after 14 days. Remember, prevention is great.
In case of extensive damage to wood by bark beetles, you need to act in a radical way. Areas with the largest focus of damage must be cut off and destroyed with fire. The surface must be covered with a polyethylene film, so that all sawdust, shavings and chips are collected. This will keep entire areas from getting infected. Since power tools carry sawdust around the area, thereby facilitating the passage of beetles and larvae to new untouched areas, it is best to use mechanical equipment.
It's longer, but safer.
In order to restore the damaged area, it is necessary to cut a piece of the required size from clean wood, and then glue it in place of the cut. The surface must also be treated with any of the above agents.
Industrial insecticides are used to kill bark beetle in a wooden house when the area of beetle infestation is very large , and home methods cannot cope.
It is very important to study the instructions before use, and follow all the recommendations specified in it. Strict adherence to proportions is the key to success. Do not forget about safety precautions, because you are working with chemicals. Protect eyes, skin, respiratory organs with special protection. After finishing work on processing, be sure to take a shower.
B lately this method has become more and more popular. Let's figure out why he is so attractive. The trap is a plastic construction with a plate with pheromones inside. This is a substance that beetles secrete to attract their own kind.
Beetles, sensing the smell, fly at him, while stumbling upon the partition and falling to the bottom.
There is no way to get out of there. They hit the plastic partition of the structure and roll to the bottom of the glass, from where they cannot get out on their own.
It is very encouraging that pheromone traps for insects are absolutely safe and environmentally friendly. But, nevertheless, the effectiveness of this method raises a lot of controversy and doubt.
With the help of this device, only adult bark beetles are caught, pheromones have no effect on eggs and larvae.
The greatest damage to wood is caused by the larvae of beetles. Also, it was noticed that beetles do not always fall into a trap, but immediately begin to master a fresh tree nearby. In this situation, the larvae that eat the tree, eventually turn into adult beetles, which in turn continue to actively reproduce, and so on in a circle.
But, despite this, traps with pheromones can attract bark beetles, which are born at kilometers distances. Thus, this device can play a cruel joke.
Instead of getting rid of bark beetles, you can only achieve an increase in their number.
Hypothetically, pheromone traps are best used in large areas, such as in a forest. For wooden houses, this method does not seem to be suitable.
In case of large-scale damage to houses by bark beetles, it is more rational to use phosphine fumigation.
The strength of this method is that gas is capable of penetrating all the moves made by bark beetles, and completely destroys it at all stages of development. It is advisable to entrust such a procedure to professionals, therefore, a gas mask, protective suit and special equipment are required for work. Also, phosphine is poisonous, and after processing the premises, all rooms must be left to ventilate for several days, as well as determine the concentration of gas, and process the residues.
Such method of fighting bark beetles as electromagnetic radiation of high frequency - microwave is gaining more and more popularity.
Affected wood is heated to 60 o C using a special microwave radiator. This method showed itself from a very good side, because the destruction of insects occurs at any stage of their development. Electromagnetic radiation does not affect the condition of the material, so the appearance is preserved.
Remember that, regardless of which method of killing bark beetles you choose, what you start must always be brought to 100% of the result. The complete destruction of insects, down to the laid eggs, can guarantee getting rid of the scourge.
It is necessary to start the fight against grinders even from personal plots. Engage in bird attraction by hanging out feeders. After all, they are the orderlies of the forest. This method is quite effective and will help reduce the population of pest beetles.
Get rid of old trees, stumps, dead branches in order to take away their habitat from beetles.
All this must be taken out and burned. In the fall, clear the area of fallen leaves.
With the onset of spring, treat the bark of trees with slaked lime in the proportions: 1 part of lime and 1.5 - 3 parts of water. This will prevent tree infestation.
Mix the ingredients together to prepare the solution in a large container. In the first hour, there will be a violent reaction - seething, hissing, temperature rise. After an hour, stir the mixture with a stick. This must be done with caution so as not to burn yourself. It is best to use protective goggles and gloves when working with lime.
You can start whitewashing the trees after 2 hours, or later. The lime should be well extinguished.
After the trees bloom, prevent the bark beetle by spraying. Because it is at this time that a massive invasion of insects occurs. For processing, substances such as Lepidocide, Bitoxibacillin, Boverin are suitable.
These drugs are highly effective and environmentally friendly. The procedure must be repeated after 14 days.
Check the tree bark frequently for holes. If affected, treat immediately with insecticides that have a high level of environmental safety.
If the area of tree infestation is large, it is necessary to apply chemicals.
Confidor Extra sneaks into the tree and paralyzes the beetles. Clipper lingers on the bark and destroys beetles on the surface In case the situation is out of control and the tree cannot be saved, it is better to cut it down and dispose of it.
In order to avoid damage to the house by bark beetles, it is necessary to maintain optimal humidity in the room. These beetles prefer moist material. Ventilate rooms and dry the house.
A hygrometer will help determine the level of humidity in the house.
Strongly damp wooden walls are dried using an electric heater and a heat gun. Provide air circulation by opening doors and windows, or use a fan for this purpose.
Open the wood with paint or varnish to protect it from bark beetles. Or use a ready-made, purchased bark beetle remedy.
You can take care of such surfaces with the help of Polish or Gloss. They contain components that repel insects.
Uncoated surfaces are protected with sodium silicofluoride. Make a solution of 200-250 g of the substance and 10 liters of hot water, cool to room temperature. Wipe the wood with a soft cloth.
Please note that the moves that bark beetles gnaw are divided into types.
Perhaps knowing these nuances will help you see the problem in time and start fighting it.
Bark beetles are able to gnaw their moves deep enough. Therefore, not all tools work equally well.
Liquids working on the surface of the wood - oils, sprays, etc., will not be able to penetrate. Coating with varnish will block the access of air, bark beetles will not be able to exist in such conditions for long, some will die, others will not be able to get inside.
Such methods of fighting bark beetles as injection, heat treatment and exposure to fog are performed by specialists. There are services that do preliminary diagnostics and treatment of wood from beetles.
