Finally, a dream came true: they built a wooden house or a bathhouse, put a log house or bought wooden furniture. Time passes, and ticks, clicks, rustling are heard in the house. What is it, you think? The answer is simple: there are bugs feeding on a tree in the house. There are a lot of species, but the main pests of wooden structures are bark beetles, barbel, grinders, woodworms. Fumigation with phosphine of a wooden house from beetles is one of the most dangerous methods in the pest control market.
Signs of bugs in the house:
Drilling flour (shavings, wood dust). It can be seen on the walls or on the floor.
Strokes and openings (inlet and outlet openings).
Extraneous sounds such as ticking, rustling, chirping.
The worst thing in this situation is that getting rid of bugs on your own is almost impossible. All methods aimed at the destruction of the beetle in the thickness of the tree are superficial. They do not harm the larva, which is located in the thickness of the wood and eats the tree from the inside.
There are quite a lot of proposals and ways to destroy beetles in a wooden house on the market, but having studied some of them, we strongly doubted their effectiveness.
Ineffective methods of controlling bugs include
Processing by generators of hot and cold fog and insecticides inside the house. The larva clogs its course with drill flour and feces, and no, even the smallest aerosol spraying through such a “plug” will not pass into the course.
Extrusion of wood with insecticides. It is also a very dubious method, because the tree is dead and cannot carry the product by itself with a current of resin and juice. Accordingly, it is necessary to drill and pour the agent in increments of a couple of centimeters. And why then a house made of wood, if it is saturated with chemistry?
Impregnation from beetles. At the stage of infection, they are already ineffective, since they are superficial in nature and are not able to penetrate the thickness of the wood to the larva of the bark beetle or barbel beetle. Various means for protecting the tree from beetles should be used at the stage of construction or wood processing as a preventive measure.
It often happens that for the construction of a wooden house, material infected by beetles is already used. Timber, boards, logs due to improper storage were damaged by a beetle. It is not uncommon that unscrupulous developers used the material of sanitary deforestation damaged by a bark beetle, which must be burned. Such a tree is cheaper and quickly finds its customers.
So what to do if the house is built and there are beetles in it? In recent years, the service “Phosphine fumigation of a wooden house” has appeared on the disinfection market. Let's see what it is.
Phosphine fumigation of a wooden house from beetles
Phosphine fumigation is the use of PH3 gas (hydrogen phosphorus), which belongs to the 1st hazard class of drugs (extremely dangerous). The method was originally developed for the destruction of pests of grain and crops. It is used in warehouses, elevators and in storage barns. The method proved to be excellent, and they began to use it for fumigation of wooden houses.
What means are used for fumigation?
The main tool for phosphine fumigation of wooden houses and structures from bark beetles, grinders, wood borers and other wood pests is magnesium or aluminum phosphide. Responsible fumigation companies use magnesium phosphide, since it decomposes completely and the residual dust does not contain metallic phosphide, which is dangerous. In simple words, after fumigation, your home is completely safe, and there will be no trace of the used funds in the room.
What you need to know before fumigation with phosphine of a wooden house from beetles?
Phosphine is a preparative gas (tablets, tapes, plates). It is mortally dangerous and belongs to the 1st hazard class, therefore only persons with professional training can use it. It is unacceptable to use funds for fumigation on your own or to persons who do not have a certificate of special training. The company must also be a member of the National Organization of Disinfectants (NP "NOD") and have a certificate confirming this.
Fumigation lasts several days (from 5 to 7) and is carried out exclusively at a positive ambient temperature. Thus, the service is strictly seasonal and cannot be carried out in the winter. Gas from beetles is released only at a positive temperature.
At the time of fumigation should leave the room, and you can not go into it during the entire exposure. Only after the fumigation specialist arrives a second time and carries out degassing (removal of spent metal phosphine residues from the room), you can use the house.
Why is phosphine fumigation the most effective method?
Phosphine or phosphorous hydrogen released during home treatment (fumigation) is an extremely dangerous compound and toxic to all living things. The slightest concentration of gas is enough to kill all living things in the zone of its action. Since gas is 1.5 times heavier than air, it, squeezing out air, penetrates all the moves and gets to all the larvae and beetles in the room, leaving them no chance. They die from acute toxic poisoning, which cannot be achieved using other methods or insecticides.
How to choose a company for fumigation
- Certificate of professional training of personnel (including fumigation).
- Certificate of membership in the National Organization of Disinfectants (NP "NOD").
