Regulations
In the new
Articles L 112-17 and R 112-2 to 4 of the Construction and Housing Code and their implementing decree of June 27, 2006 provide in particular for the protection of wood and wood-based materials contributing to the solidity of the work against insects with xylophagous larvae and this throughout the national territory. These provisions concern constructions for which the permit has been filed
after November 1, 2006, as well as development work undertaken as of that same date.
In the old
There are no specific regulations regarding
preventive or curative treatments in the old against
insects with xylophagous larvae in the existing building.

Capricorn of the Houses
Attacks resinous essences
- Egg laying: 20 to 100eggs.
- Larva: larval development
from 3 to 5 years old.
- The adult insect: 10 to 20 mm long,
black color, release from june to august, ne
lives only 3 to 4 weeks, flies on
short distances.
Presence indices:
• Exit holes:
oval, 6 to 10 mm
• Galleries that
extend up to
the outskirts of
the book
• Worms:
sawdust cylinder
compressed by 1 mm
DRY WOOD INSECTS
Insects whose larvae develop and feed on the wood creating
galleries.
The best known: capricorn, hesperophanes, lyctus, small and
large beetles.
Their presence is mainly detected by the exit holes of the
larvae when they reach the adult stage.
The big watch beetle
Particularly attacks wood
(hardwoods and softwoods) that have already undergone
degradation by a fungus
cubic or fibrous rot, therefore at a
higher than normal humidity.
- The adult insect: 5 to 7 mm long
dark brown color, appears between April
and May, lives 1 to 10 years.
• Exit holes:
flyers
from 2 to 4 mm
• The galleries :
flyers
• Worms:
grainy shaped
of 1mm lens
diameter
other insects
wood-boring less
widespread or
nest builders, can
do damage in
lumber :
- THE BOSTRYCHE CAPUCHIN
- THE XYLOPHAGOUS WEEVIL
- THE ANT
- THE CARPENTER BEE
treatments
Each situation requires a precise diagnosis allowing then to make the choice of the most adapted treatment.
It should be noted that the preparation and treatment operations are inseparable from each other in order to guarantee a result.
Effective control requires:
Precise preparatory operations such as:
- mechanical sounding of all timber,
- the logging of the worm-eaten parts, an essential step in
the effectiveness of the treatment,
- brushing and dusting of exposed galleries and
the entire wood surface.
Treatment methods:
BY INJECTION
Technique of more than 20 years of existence which consists ininject biocidal products inside the pieces of wood through specially designed injectors and pumps.
This is an immediate and curative treatment approach that only a professional holding the Certibiocide aptitude is authorized to carry out.
BY SPRAY
Technique of more than 20 years of existence which consists in spraying biocidal products on the exterior of the wooden parts using specially designed pumps. This is a preventive treatment approach that only a professional holding the Certibiocide aptitude is authorized to carry out.
