Finally, a dream came true: they built a wooden house or a bathhouse, put up a log house or purchased wooden furniture. Time passes, and ticking, clicking, rustling are heard in the house. What is it, you think? The answer is simple: beetles feeding on wood have started up in the house. There are a lot of species, but the main pests of wooden structures are bark beetles, barbels, grinders, and wood borers. Phosphine fumigation of a wooden house against bugs is one of the most dangerous methods on the pest control market.
Signs that the house has bugs:
- Drilling flour (shavings, wood dust). It can be seen on the walls or on the floor.
- Moves and holes (inlets and outlets).
- Extraneous sounds such as ticking, rustling, chirping.
The worst thing about this situation is that getting rid of the bugs on your own is almost impossible. All methods aimed at destroying the beetle in the thickness of the tree are superficial. They do not harm the larva, which is in the thickness of the wood and eats the tree from the inside.
There are quite a few on the marketsuggestions and ways to kill bugs in a wooden house, but after studying some of them, we strongly doubted their effectiveness.
Ineffective methods of dealing with beetles include
-
Treatment with hot and cold fog generators and insecticides inside the house. The larva clogs its passage with drill flour and feces, and no, even the smallest aerosol spray through such a “cork”, will pass into the passage.
- Syringing a tree with insecticides. It is also a very dubious method, because the tree is dead and will not be able to spread the product on its own with a current of resin and juice. Accordingly, it is necessary to drill and pour the product in increments of a couple of centimeters. And why then a house made of wood, if it will be impregnated with chemistry?
- Beetle impregnation. At the stage of infection, they are already ineffective, since they are superficial and are not able to penetrate into the thickness of the wood to the larva of the bark beetle or barbel. Various kinds of means to protect wood from beetles should be used at the stage of construction or wood processing as a preventive measure.
It often happens that beetle-infested material is already used to build a wooden house. Timber, boards, logs were damaged by a beetle due to improper storage. It is not uncommon that unscrupulous developers used material from sanitary felling of forests damaged by bark beetles, which must be burned. Such a tree is cheaper and quickly finds its buyers.
So what to do if the house is built and there are bugs in it? In recent years, the disinfection marketthe service "Fumigation with phosphine of a wooden house" appeared. Let's find out what it is.
Phosphine fumigation of a wooden house from beetles
Phosphine fumigation is the use of PH3 gas (hydrogen phosphorous), which belongs to the 1st hazard class of means (extremely dangerous). The method was originally developed for the destruction of pests of grain and crops. It is used in warehouses, elevators and stock barns. The method proved to be excellent, and it began to be used for the fumigation of wooden houses.
What products are used for fumigation?
The main agent for fumigation of wooden houses and structures with phosphine from bark beetles, grinders, wood borers and other wood pests is magnesium or aluminum phosphide. Responsible fumigation companies use magnesium phosphide as it decomposes completely and the residual dust does not contain metal phosphide which is dangerous. In simple words, after fumigation, your home is completely safe, and there will be no traces of the products used in the room.
What you need to know before fumigating a wooden house with phosphine from bugs?
Phosphine is a gas in a preparative form (tablets, tapes, plates). It is deadly and belongs to the 1st hazard class, so only persons with professional training can use it. Use fumigation products by yourself or by persons who do not have a certificate of special training,unacceptable. Also, the company must be a member of the National Organization of Disinfectionists (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 winter. Gas from beetles is released only at a positive temperature.
For the duration of the fumigation, you should leave the room, and you can not enter it during the entire exposure period. 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 hydrogen phosphide released during home processing (fumigation) is an extremely dangerous compound and is toxic to all living things. The slightest concentration of gas is enough to kill all living things in the zone of its action. Since the gas is 1.5 times heavier than air, it, squeezing out the air, penetrates all the passages 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 fumigation company
- Certificate of staff training (including fumigation).
- Certificate of membership in the National Organization of Disinfectionists (NP "NOD").
