Xylophagous in the house

Xylophagous insects, and termites in particular can cause significant damage in buildings, degrading wood and its derivatives used in construction. their activity can affect the quality of use of buildings but also cause significant disorders in their very structure. in the most extreme cases, it can lead to their collapse.
The risk of degradation of construction by termites and other Xylophagous insects should nevertheless not be considered a scourge. Simple measures are enough (such as the establishment of preventive devices during construction, regular monitoring and maintenance of construction and its surroundings, etc.). for this risk to be mastered and that any infestations of a building do not extend and do not spread to the rest of the building.

By setting out the methods of prevention and control of termites and other xylophagous insects, the existing legislative and regulatory framework aims to control the risk of degradation of constructions by these insects (by the protection of wood and wood-based materials but also the protection of the Sol/Bâtiment interface)

Assess the state of the premises

xylophages dans la maison First, consider the situation.
A good cleaning will allow you to see more clearly. consider protecting yourself from dust with an adequate mask.
1 - Try to recognize the essence of the woods, which can be very diverse (fish, chestnut, poplar, resinous)
2 - Sound the pieces of wood that appear to be attacked by using a large screwdriver, especially the recesses in the walls and where there are traces of moisture. of sawdust on the floors indicates a recent activity.
3 - Don't trust appearances. an oak beam can have the alber completely swept by the calfs, but try to plant a nail and you will be reassured about its solidity. However, a bunny chevron where only a few capricorne holes may have to be doubled or changed.
4 - Do not forget the floors, the stairs, the oilseries (entrance door of the termites), it is sometimes the painting that holds the whole.
5 - If your inspection takes place at the beginning of the summer you may see adult insects. Indeed, capricornes and vrillettes, after 4 to 5 years (or more) spent to nibble, will turn into an adult insect and think to go out to mate and reproduce if you are in a term area and if you have any doubts, bring someone competent.


Insects with larvae

le termite - reticulitermes-lucifugusXylophagous insects are very often responsible for significant damage to various pieces of wood. females lay eggs in wood interstices. of these eggs are born larvae that develop inside the wood and dig galleries there.

Wood in our habitats is a poorly welcoming environment for insects: it is a hard and dry environment, the source of food is not rich in nutrients and often difficult to access. For this reason, few species have chosen this medium to lay their bridges there, which will give birth to larvae with powerful mandibles and able to degrade wood. These larvae have very slow growth and will feed on wood that often shelters them for long years. the most frequently encountered Xylophagous larvae insects in the woods used are the following.

How to treat xylophagous insects ?

1 - when to treat ?
One can treat all year except during extreme periods, very cold or very hot. With our insecticide, we don't need to get exiled. simply provide a good ventilation during the duration of the treatment, which you can perform yourself.

2 - Burning
It is useless to put product in vermoulu and spongy wood, product loss and especially low efficiency. It is therefore imperative to remove all damaged parts, until reaching a healthy and hard wood. This operation will also allow you to control the condition of the beams.

3 - proceed with treatment
In any case, after a good stripping, for woods of weak sections (

For section parts ≥80 cm 2 and depending on the essence of wood, injections will be required to insulate the product in depth. In general, to perform this work, drill holes around 25 cm and up to 3/4 of the thickness of the wood, then inject approximately 0.3 dl to 0.5 dl / insecticide hole.

In the case of parquet "a washing" to the insecticide gives an excellent result.

N.B.: It is obvious that if the insect invasion is strong and your woods have been clearly attacked for years, it will be necessary to use specialized and aggregate companies that will establish a complete diagnosis and appropriate response solutions.

Some simple rules to limit the installation of xylophagous

The obligation to protection of wood and floor/building interface does not provide regular monitoring and maintenance of construction and its surroundings. a number of so-called “at-risk” behaviours can in fact promote the installation and development of underground termite colonies in the vicinity
or inside a building itself. The prevention of termite risk is therefore also the responsibility of the occupants, whether they are owners, tenants or technical personnel.
The following recommendations are intended to inform and sensitize everyone on the preservation of their housing or property. In addition to the prevention and control of termite infestations, the following measures are used to contribute to the maintenance of adequate sanitation and hygiene conditions in buildings.


Delete them water infiltration: water infiltration in the seating can affect all types of buildings. they come from failures or absences of peripheral drainages ( pluvial water, sources, etc.);

Delete them ascended capillaries: this phenomenon appears mainly on the old building, which usually does not have sealing barriers and is often made up of full and porous materials (including natural stone type);

Monitor them condensation phenomena : linked to excessive moisture presence in the walls, they can lead to the development of fungal attacks and the installation of underground termite colonies;

Not cumbersome cellars, basements and sanitary vacuums of cellulosic elements ;

Good ventilator cellars, basements, sanitary vacuums, etc.


Delete them stagnant water points near buildings (lost properties, etc.). ;

Eliminate all dead wood at the building’s premises and systematically avoid storing firewood, pallets, and in a more general way any cellulosic element to the floor and in contact with the walls (papers, cartons, wood debris, etc.). ;

Avoid plantings near immediate walls : the presence of too dense vegetation near the building can be a source of repeated or permanent humidification of the exterior walls. it can also be at the origin of a deterioration of foundations following an uncontrolled development of root systems.
