TERMITES: Protection & Control
Regulations
In the new
Since November 2007, the law imposes by the decree of May 23, 2006, followed by decree no. construction to prevent termite infestations at these future constructions.
This decree and order are applicable to all areas covered by a prefectural order; depending on the department, this can range from the infested municipality to the entire department.
The planned measures are defi ned at the level of the Construction and Housing Code by articles R 112-2 and R112-3; they concern the installation of protective devices between the ground and the building against the action of termites, i.e.:
• by implementing a device
of the physical or physico-chemical barrier type,
• by the implementation of a construction device
controllable (except for overseas departments).
In the old
The termite law by decree n°2000-613 of July 3, 2000 provides:
• for the owner or occupant of a building, the obligation to declare to the town hall the presence of termites at the level of his property,
• for the prefect, the possibility of issuing an order delimiting the infested areas,
• for the mayor, the possibility of injunction of diagnosis and/or treatment at the level of the citizens,
• for the owner, the obligation to carry out a parasitic state within the framework of a sale.
Biology
Subterranean termites
Subterranean termites are social insects that live in colonies (termite mounds) and are organized around different castes:
breeders, food workers and soldiers.
Their mode of development is either by swarming (the winged insects founding a new colony), or by cuttings (a hundred individuals from the colony can give birth to a new colony). Their natural habitat is the forest, where they actively participate in the recycling of dead plant matter.
Termite colonies are settled in the ground; it is the workers (several thousand individuals) who prospect in a
permanent foraging based on cellulose; it can be wood, but also paper, cardboard… In their quest
food, they are also capable of degrading many materials (polystyrene, insulation, sheaths of all kinds, etc.) and
pass through gaps of the order of 1 mm to continue their journey inside the buildings.
Main signs of presence
Termites attack all species of wood except the heartwood of some particularly dense tropical species.
• Presence of gaps always empty of
vermoulage lined with concretions.
• Galleries, tunnels or cords
built on hard materials,
• Small holes of approximately 2 mm visible
on ceiling plaster or walls.
treatments
Two control techniques at the level of an infested building:
CHEMICAL BARRIER
Technique of more than 50 years of existence which consists in putting inartwork biocidal product injection barriers at the level of the exterior floors, at the level of the cellars, sols exteriors, masonry, structural wood and other woods.
This is an immediate treatment approach that only a professional holding the Certibiocide aptitude is authorized to carry out.
BAIT TRAPS
Technique of more than 20 years of existence which consists in setting up stations (trap) on the whole of the perimetry of the building to
protect, as well as on the traces of passage of termites. The principle is to be able to connect with the colony present via the workers and to gradually intoxicate the whole colony. This is an approach requiring monitoring of the site over several months by the company in order to assess the state of intoxication of the colony and the evolution of the infestation.
This last technique can also be used in the case of field treatment, in a preventive and curative way.
