Who's the termite ?

Termite - Reticulitermes lucifugusOrder : isopteres
Family: rhinotermitide, kalotermitide
Size: 2 to 8 mm
Location: all woods
Period: all year

Termites are xylophageal insects. they degrade the wood and any other material containing cellulose, which forms the basis of their diet (paper, cardboard, certain tissues, etc.)

There are 3 species that can be found in our climates:

the termite lucirous (reticulitermes lucifugus,) le termite of saintonge (r. santonensis) and the termite with yellow neck (kalotermes flavicollis).


What you need to know about termite

Termite - Reticulitermes lucifugusNative to tropical countries, termite can only live in a natural state in warm regions. living in colonies of several thousand individuals, the first two species have their nests on earth. the termite with yellow neck, however, settles in the dead and dry wood. their natural habitat is the forest, where they actively participate in the recycling of dead plant matter. As a result, the status of “vagant” that is frequently attributed to them only applies in the case of infestations of works born from the hand of man (buildings, exterior fittings, etc.).

Preferably feeding on slightly wet wood, termite can also feed on paper, cardboard and, in the event of a shortage, on a living tree. Its color is not well defined. Indeed, its hues being transparent, it can take the color of the wood that it ate.
Ouvrier de Reticulitermes
Termite - Reticulitermes lucifugusThis insect attacks all resinous and leafy wood species. it practices galleries always respecting the outer surface of the wood, which can be reduced to the thickness of a sheet of paper.
This insect leaks light. it does not circulate in the open air, but in galleries dug in the ground or in the wood, or in galleries it makes itself with a mixture of earth, saliva and excrements.
These galleries are always lacking of vermoulure to allow intense circulation. their walls are covered with earthy coating.
The colony does not settle directly into the woods, but in the ground, and arrives to the woods of the buildings by galleries.

Termites are social insects, forming colonies organized in castes. workers, soldiers, nymphs, breeders and larvae coexist and interact perpetually with complex and elaborate modes of communication (vibrations, chemical signals, food exchanges, etc.).

The working caste represents the vast majority of the colony (on average 90 to 95 per cent of the individuals in the case of underground termites encountered in metropolis). It is the workers who cause damage to the woods, whether they are stored wet on the ground or dry and implemented.

Signs of presence or activity of termites

- earthen cords and earthy concretions : the aerial galleries built by the termites on the surface of the elements unfit for their consumption ( running along the facades or trunks of living trees) are the most obvious external signs of an infestation by the underground termites;

- scattered wings on the ground (test marks);

- damage : wood of leafy appearance, with earthy galleries, “masons” ;

- live termites : winged individuals emerging from strains, workers seen after removing a piece of wood stored on the ground, etc.

Each person is in a position to ensure minimal monitoring of the building he occupies (or to carry it out), through regular inspection, both outside and inside, of the elements and places conducive to the installation and development of a termite colony.



- plants, strains, shrubs, dead or deperating trees;

- any wood in contact with the ground: tomato pickets, benches, fences, garden shelters;

- enclosure walls, mainly in part low and at the level of cracks;

- eyes, air vents, sheaths and pipes.


(mainly lower levels)

-Floors and walls of cellars, basement, sanitary vacuums;

- ventilation devices, electric sheaths, etc.;

- wetlands: under sink, bathtub, etc.;

- dark places not visited: below the stairs, etc.;

- parquets covered with waterproof coating.


Damage to termites

Live trees are not always immune to attacks, termites that can sometimes defeat the diminished natural defenses of certain trees weakened by pollution or other pests (a mites, caterpillars, defoliators, etc.). metropolitan essences are almost all sensitive to termite attacks, which degrade all parts of the wood (wood and wood of heart). The activity of the termites is the cause of many claims in the infested areas. the loss of material resulting from the colonization of a wood by termites can, in extreme cases, make it quickly unfit to ensure its role and cause ruptures of parts of works.

How to fight termites ?

1 - preventive measures
  • Check all the woods and furniture you bring back (working insects can reform a colony).
  • Do not leave nearby houses any wood, paper or cardboard that can feed them.
  • Use in construction only processed woods.
  • According to your department and your obligations: the obligation toprotection of wood and floor/building interface 

For all diagnostics and treatment method, you can read our file on this subject.

2 - curative

Based on current regulations, wood products for xylophageal insects, whether preventive or curative, must contain at least one active substance belonging to the TP8 biocide class.

The problem is that currently in this class, there is no natural active ingredient allowed.
Most often, in wood-processing products, cypermethrin is found with a solvent (white spirit, citrus, water, ...). whether with or without odor, these treatment products containing components of petroleum origin are not very healthy in a place where you live !
But termite is an insect. and to kill an insect, an insecticide is used to belong to TP18.
So you can use to kill the termite a natural insecticide. This insecticide will not have any wood protection function, unlike products for wood processing. But he'll get you out of termites.
Although it may seem obvious, do not try to treat a target, painted or varnish wood. This will not serve anything, to be effective treatment must be done on raw wood.
The solution, a little long but effective to kill termites, is to penetrate the insecticide into the holes made by these insects (seringue, spray, sponge, serpillère).

3 products may be suitable for this purpose:

1 - Our insecticide 4j all insects (4j to 5%). This 500ml vaporizer will allow you to process about 5 m2. for larger surface use this same product but under its concentrated formAnd you'll make a 5% dilution. It must be known that this product, based on plant pyrethra with short remanence. It will therefore be effective in early curative action but not long-term curative action. from the moment the insect will becontactWith the product 4j, it will die instantly (the neurotoxic effect of the pyrethre). the difficulty remains to touch these refugee insects in the heart of wood parts or even at times in inaccessible places (under a floor for example). the best result will be to apply it by injection (with a small syringe) in the larger holes left by the insect.

2 - THE extract of margosa. the main property of margosa is to make unfit for insect consumption all treated surfaces, insects must then either leave the treated area in search of food or starve. thanks to its wide spectrum and long-lasting action, margosa is effective in most infested locations. spray or injection application. margosa blocks larvae development, disrupts food research and sterilizes adult insects. treatment will be to be carried out in vaporization on the wood or by injection directly into the holes with a concentration of 2% in preventive use, to 4% in curative.

3 - The diatomaceous earth to spray. if the holes (galerie) left by the insect in the wood parts are large enough (+ 2 mm), the diatome to spray as aerosol can be used. Thanks to its application tube, you can apply the diatom in each hole and inject it into the deepest. diatomed soil, thanks to the specific surface of its grains and its silica skeleton is dreadful to fight against creeping insects:

a -Ingestion of silica particles (very sharp) by insects causes lesions of their digestive tube.

b -The finesse and hardness of the silica particles amassed by the insect's silks cause lesions on its members or on its shell. This results in the insect a loss of body fluids that leads to its death by dehydration after a few days. the absorbent properties of the diatomy earth (up to 150% of its weight) favor this process.

Frequently asked questions about termite

Q: Hello I would like to use an organic anti-termite product to eliminate termites of a wooden pilon. The concern is that I intend to use it to stack food. If I use a organic product to eliminate these termites, could I always use my pilon to prepare dishes ?
R: It seems difficult for you to have termites in a wooden pedestal. In fact, these insects make their nests in the ground, but it can very well be vrillettes, capricornes,. Put your pilon for a few days at the freezer, the insects will die.

Q: How to process an old platanum, still very beautiful, but with kalotermes
R: The most effective and simple is to find the termitière and destroy it. it is possible that it is at the foot of the tree in the ground.

Q: I wish to treat old furniture by capillarity (feet that dip in a product). Do you have a product similar to xylene ?
R: Our 4j insecticide can be used to treat furniture but it is totally different from natural xylene and not water solvent synthesis and not contact oil distillate and non neurotoxic. treat by capillarity is a solution but I'm not sure that the product can treat the entire piece of furniture or then it will take a lot of time.

Q: You have a product against external termites, not for houses. Thank you for answering me quickly.
R: Insecticide 4j, on the other hand its formulation based on pyrethre will be effective but in direct curative treatment on insects. the product will degrade rather quickly due to the action of the uv and the heat. the margosa has a slower but much longer action in time. It will therefore be the best of 2 products for external use.

Q: You recommend 150ml/m2 but diluted to how much? I have an attic of 60m2 and apparently it's not termites because sawdust and nonspecies of piles like mud.
R: When spraying on the wood, a concentration of 3.% can be used in injection, it is best to use a concentration of 5.%.

Q: We live in a mansarded apartment with many apparent old beams. Can we treat this cartridge against the capricornes and possibly against the termites while living in this apartment ?
R: It is always better to treat as a preventive treatment than in curative. in preventive, you treat by spraying or badigeon but in curative the treatment is done by injection. but be careful not to treat that exposed beams, insects can also settle in those that are not visible. if you live in use preferably organic products to avoid poisoning.
