Treatment of structural timber against xylophagous insects

The wooden frame requires regular maintenance. Unlike metal or concrete, wood can be prone to attack by wood-boring insects that can weaken the strength of the construction. This is why an in-depth treatment against harmful insects is essential to avoid confronting you with this major problem. 

What insects attack the frame?

Like all wooden parts, the frame is likely to be attacked by xylophagous insects after 10 years. Capricorns, lyctus, termites and woodworms are the main insect pests that devour timber. Each of its parasites has its preferences. Termites, for example, prey on softwood first, while capricorns are fond of softwoods, hardwoods and tropical woods.

Their larvae dig galleries there and feed on the cellulose. Some line the galleries, which is why they are difficult to detect. Once adults, the larvae of xylophagous insects reproduce. Treatment of structural timber is then recommended. If the wood is not treated in time, the damage it causes will be significant. The larvae of the capricorn, sirex and woodworm are, on the other hand, easy to spot. Traces of blister, sawdust, worm and small exit holes reveal their existence. The termite, meanwhile, attacks all species of Scots pine as well as Douglas fir, spruce or elm. It is difficult to detect because it drills few holes and does not produce sawdust. Its presence is only detected when the invasion is significant.

How much does the treatment of lumber cost?

The price of the treatment varies depending on the technique used. The structural treatment by injection is also suitable for curative treatment as preventive. Indeed, it is effective in protecting wood and preventing infestation, but also in exterminating larvae and insects that attack structural timber and even wood sell-off. This treatment is particularly recommended for the so-called traditional frame. He is thorough and need the know-how of an expert. On the other hand, the spray treatment is less complex. However, you must get rid of the infested and damaged parts before proceeding with the treatment. Logging is also recommended in order to find healthy wood.

In all cases, the insecticide or fungicide product used for the preventive treatment and the curative treatment must be FCBA certified. It is therefore best to contact a certified company who will be better able to find suitable treatment products against fungi, termites or others. The area to be treated can also influence the price of a structural treatment, as can the type of insects to be eliminated and the accessibility of the framework.

Depending on the specifics of the timber frame, it may be useful to call in a specialist in the treatment of structural timber. He will establish a personalized estimate depending on the nature of the insect present in the structural timber and will be able to determine the appropriate treatment: curative or preventive.
