It is essential to identify the problem immediately. Otherwise, lumber or wood furniture can become a real biological weapon. Lets take a look at signs of wood infection from pests.
- The visible remnants of passages on the wane indicate a “surprise” in the wood in the form of a bark beetle.
- If the board has no visible signs of damage, but at the same time is surprisingly light, termites can live in it.
- Wood flour can indicate the presence of any insect from the above trinity.
- It will not be possible to eliminate defects in damaged wood. Insects live “in grand style,” equipping many passages. Therefore, if you see that the purchased lumber has a “bonus” in the form of a pest, it is better not to buy it at all, even at a low price. If you have already purchased boards, beams, lining, and there is no way to return the lumber, you better burn it. This will prevent the spread of pests throughout the site.
- You can even hear the larvae: during the destruction of wood, they emit a grinding sound.
Wood Pest Control
As in medicine, methods are divided into prevention and treatment.
- Antiseptic treatment. The most affordable, but not the most unreliable method of processing lumber. The composition is applied to the surface of wood products before their storage or before their intended use. It is characterized by shallow penetration of the solution deep into the wood species, only about one millimetre. Temporary protection, on average, from one to five years. After the expiration date, it requires a new treatment.
- Thermal method – special ovens are needed for it, in which the wood is heated to 140 degrees Celsius. As a result of heating, the nutrients of interest to insects break down. As a result of heating, moisture also evaporates as a result of which the density of the wood increases. The downside to this process is the price. Thermally treated wood is much more expensive.
- Autoclavingis one of the best ways to protect the wood. They are used to protect the most expensive wood species. An autoclave is a sealed container into which a product is placed. The antiseptic, supplied under pressure, penetrates deep into the wood’s structure, which protects it from pests. But the method is not cheap either. The cost of autoclaved lumber rises by at least half.
