Pest diagnosis

What is a pest diagnosis?

Parasitic diagnosis
Despite their small size, wood-destroying fungi and insects are a real threat to buildings. By attacking wood, they are able to damage even the most modern buildings.

The easiest way to prevent such a disaster is still to use a diagnosis of pests. In wetlands, notaries strongly recommend that it be carried out before selling a building. Indeed, although not compulsory, a pest control allows the seller to avoid accusations of a hidden defect.

What is a pest diagnosis?

Without you even knowing it, your home may be under attack. As you go about your daily business, behind your baseboards, under your floors and in damp areas, a infestation is hard at work. Without making a sound, fungi and insects devour your wood from the inside.

A Pest diagnosis (DEP) is an examination that can identify not only wood-destroying fungi, but also insects that can damage wood. It is non-invasive, but requires professional equipment to give conclusive results.

What species are searched for during a PED?

Two types of living organisms usually attack wood: insects and fungi. In each case pest controlThe agent must look for the presence of these organisms.

Which fungi are searched for during a PED?

Beware... Even if fungi have a particular liking for wood, not all species are necessarily harmful. In fact, depending on the extent of the damage, mycotic agents are divided into two categories:

  • Lignicoles ;
  • lignivores.

In the first case, the damage caused by the parasites is only aesthetic. In contrast, wood-destroying fungi damage the structure of the wood itself.

Of all the fungi species implicated in the infestationsOne that gives nightmares to even the most experienced operators. It is the weeping merula, a fungus that can grow at relatively normal humidity levels.

Which insects are actively sought during a PED?

Unfortunately, there are many categories of insects that can degrade wood. In fact, there are currently four main groups, namely

  • Wood-eating insects with a preference for dry (or indoor) wood;
  • Wood-boring insects prefer fresh (or outdoor) wood;
  • nesting insects ;
  • termites.

The most damaging insects in the households are the wood-eating larvae. In order to change from larvae to pupae, these organisms feed extensively on wood. In doing so, they cause irreparable damage to the frame and other woodwork.

It should be noted that although the pest control is in no way equivalent to a termite diagnosis. If you think that your home has become a haven for these dreaded insects, you should opt for a specific examination.

When should a PED be carried out?

At present, there is no law governing the use of a DEP. However, it is customary for a notary to require one when selling a property in a wetland area. In this case, the infestation must be attached to the Technical Diagnostic File (DDT).

Another point that needs to be considered is the period of validity of the EPD. As it only attests to the state of the premises at a given moment, it does not provide any additional guarantees. Nevertheless, it allows the seller to protect himself against a potential accusation of a hidden defect.
