A beetle grinder in a house is a real disaster. It is popularly called a "pretense" and not by chance. Feeling the danger, he shows his acting abilities and falls dead. Small insects cause irreparable harm to wood. How to get rid of the grinder bug, read the article.
How do insects appear in a house?
With the onset of the warm period, the female begins to lay eggs in large numbers in the holes, gnawed in advance. A week later, larvae emerge from them, which feed immediately. They begin to gnaw moves in the wood. It is the larvae that are most dangerous to humans, since they cause great damage to property. Their life activity lasts one to three years.
In the summer, development becomes active. In winter, it stops. In a room where temperature differences are insignificant, the development of larvae occurs year round. After that, pupae are obtained from them, and then adult beetles, the main purpose of which is reproduction.
Before their transformation, the larvae gnaw through the tree almost to its entire thickness, the bugs have to gnaw on the remains and go outside. The holes in diameter are very small, reaching several millimeters. But since there are a lot of beetles, the entire surface of objects or structures made of wood is covered with holes, as for the inside, it remains hollow.
Signs by which you can detect insects
On the surface of a tree affected by beetles, and inside it there are many winding passages. In addition, the process of vital activity of insects is accompanied by the release of powder, which has a yellow or brown color. If an unknown insect is found during the inspection of buildings and objects made of wood, this is an occasion to suspect the appearance of grinder beetles that have settled on the windowsill or under the threshold.
If signs of the presence of parasites are detected, you must act immediately until they have eaten everything in the house. If a wooden building, which has no value on the farm, is damaged, it must be burned. If this is not possible, using special means of controlling bugs will help get rid of insects.
Kinds
To get rid of the grinder beetle in the apartment, you need to know what type it belongs to in order to choose an effective tool to deal with it. These insects are:
- Bread grinders do a lot of harm to a person; it is not without reason that they are called omnivores among the people. Beetle larvae are a real disaster for warehouses with food products. They eat pasta, sugar, cereals, medicines, they can even eat deadly poison and stay alive.
- Woody - these grinders often live in the forest. Reproduction of larvae occurs in the wood of plants, moreover, dry and old. Houses are rare, but even if wound up, walls and furniture remain unspoiled. This type of grinder is called "forest orderlies" and is not considered a pest.
- Furniture - they are considered the most dangerous. Beetles lays its larvae, the development of which occurs in a dead tree, on any surface. The disastrous actions of grinders turn any item into dust.
- Brownies - they prefer to settle outside the house. Hibernate in the cold season.
How to get rid of the grinder bug in the house?
The fight against insects is carried out in various ways. Most often, it begins to lead when the beetles managed to breed and settle on large areas in the house. People think that chemicals can do it better. But do not rush. It is necessary to try to apply folk remedies for grinder beetles, which also turn out to be harmful to insects. If all else fails, then use chemicals. But you should always remember that for no reason, insects will not get into furniture. They can be attracted by dampness. Therefore, in order to preserve furniture made of wood and other objects made of it, the room should always be dry and ventilated. Examples of some folk remedies:
- Sodium fluoride or silicofluoride, the concentration of which does not exceed 2.5%, is dissolved in water. The resulting solution is used to treat damaged surfaces by bugs with a spray gun, roller or brush.
- Using hot linseed oil gives a good result in the fight against bugs. But since the surface can change its appearance, this method is used when it does not matter, more important is the durability of objects and their integrity.
- A mixture is being prepared, which includes resin, naphthalene, black carbolic. All components are taken in the same proportion, mixed, wooden surfaces are treated with a brush.
- Another insect control product: kerosene, motor or linseed oil. This solution lubricates wooden surfaces.
Petroleum jelly
The use of this substance is the easiest way, but long-lasting. To do this, petroleum jelly is collected in a pipette and injected into each hole made by beetles. Then all the holes are filled with molten wax, if not, with paraffin. The procedure is repeated twice a month for such a time until the beetle grinder and traces of its vital activity disappear completely. This method is more appropriate to use in a residential building, since it is safe for human health.
Turpentine with kerosene
The procedure is carried out using a brush, with which the composition is applied to damaged surfaces. But first you need to cook it. For this, three parts of turpentine and one of kerosene are taken, everything is thoroughly mixed. You can add a little naphthalene to the composition, but it must be dissolved in advance with gasoline.
The temperature in the fight against the grinder
If a beetle grinder is wound up in the house, you can get rid of it with the help of high temperature. For this, any equipment is suitable, for example, a hairdryer, with which you can warm the air to 60 ° C. But such a temperature is detrimental to adults. Larvae die at low temperatures, two degrees or more below zero. If you create such conditions in the house, you can get rid of the larvae.
Salt
The beetle grinder can be completely destroyed with the help of a safe component - ordinary salt, which is always available in the house. The method is very effective, despite the simplicity, especially if the beetles wound up and managed to breed in the walls and furniture. This environment for insects is beneficial, since neither rainfall falls on either. It is necessary to prepare a saline solution, but thick as a dough on pancakes, and apply it with a brush, brush, rag to all surfaces that have damaged beetles.
How to get rid of a bread grinder?
If this type of beetles appeared in the house, all cereals available on the farm should be sieved immediately through a sieve, and then heated in an oven at a temperature of 110 ° C. Flour cannot be processed in this way. Peas are poured with salt water, all the bugs from this will float up, after which the product should be dried. An easier way to get rid of this type of insect is to place food in the freezer for a day. During this time, all beetles and their larvae will die.
Grinder insecticides
If the bugs have been “hunting” in the house for a long time, it will be difficult and long to get rid of them with folk remedies. People resort to the help of proven insecticides. Liquid preparations are more effective, it is more convenient to apply them to the surface with a spray. So they will penetrate the most inaccessible places, hitting beetles, some of which die immediately, the rest will urgently leave their shelter and crawl out. But this procedure must be done when all the residents of the house leave it, since insecticides are harmful to human health and pets.
Drug treatment will be successful if done carefully. It happens that it’s difficult to get into a place to do the processing there, which means that you need to drill a hole there. When the beetles are destroyed, seal it with wax or glue with shavings designed specifically for wood. When grinder beetles appear in a wooden house, the most effective and well-known remedies against them are:
- "Wood Bug."
- "Antizhuk".
- "Belinka Belocide."
- Empire-20.
The action of these drugs is long in time. They are absorbed into the tree, destroying insects that will no longer appear. But before using them, you should read the instructions. It is important to know: the benefit will be the drug, marked on its packaging on the permissibility of use to combat flying insects.
You can use antiseptics, such as "Mark-4." The effect is not bad if you use the product as soon as the beetles wound up in the house and did not have time to severely damage the wooden surfaces. All holes are processed with liquid, if it does not help, then completely the surface.
Fumigation - what is it, when and why is it carried out?
This is a fight against bugs, but with the use of special aerosols or smoke emitting fumigants, which are most often used aluminum, as well as magnesium phosphide. Before the procedure, people and pets must leave the room. Everything in the house, starting with food, is carefully hidden. Windows in all rooms and doors are closed. If there are ventilation hatches, they should also be clogged. Smoking insects continues for several weeks. After that, a wet cleaning is done throughout the house, soda ash is added to the water.
It is interesting
The beetle received the name "grinder" because of a peculiar sound, similar to the ticking of a clock. The fact is that he has a special shield on his chest. When an insect moves along a passage gnawed in the wood, it strikes with its device on its walls, making a sound. This occurs during breeding. So the male attracts the female for further mating.
Long ago, when the insect was not sufficiently studied, people considered the appearance of such sounds in the house a harbinger of the death of its inhabitants. This, in fact, was true, because then there were no funds that could be used in the fight against the grinder. When the beetles breed, they will undermine all the wooden structures and the structure will collapse, and people will remain under the ruins. In some states, the sound made by bugs is called the “hours of death,” and when hostilities are taking place, soldiers think that an explosive mechanism is working somewhere and quickly leave their place of deployment.
Unusually, but a fact: the beetle grinder (photo is presented for review), it turns out, eats not only wood. He is very indiscriminate in food. Its larvae exterminate bread, tobacco products, cereals, dry plaster, wallpaper glue, medicines, but they feel good at the same time, they grow and develop perfectly.
