The small and big wood beetle
There are 2 types of wood beetle : small and large. both can do considerable damage in a house. Wood beetle are xylophageal insects, i.e. their larvae circulate through the wood by digesting cellulose and digging small round holes from 2 to 5 mm. You will find traces of his passage on sculptures, paintings, old furniture ... works often made in the abyss of wood. it can also be found in ancient books and archives. Find in this folder a set of natural responses and products that will allow you to fight this insect at best.
Latin name : anobium punctatum, xestobium rufovillosum
Order : beetles
Family : anobiid
Small size =2.5 to 5 mm
Small beetle larva = 5 to 7 mm
Size bbw = 5 to 7 mm
Big cock = 6 to 11 mm
Location : in wood
Period : all year round
Its larva is a small white, soft and hairy worm that gives rise to a red, hard and trape insect whose antennas end with a small massue.
What you need to know about the wood beetle
Two species are mainly found in the dwellings: the small wood beetle and the big wood beetle. We can find them in furniture, timber and floor. Unlike the capricornes, the calf doesn't live permanently in the wood. to enter and exit the wood, it drills circular holes of a few millimetres (small wood beetle = 1 to 3 mm, large wood beetle = 2 to 4 mm). These holes are very characteristic of old furniture.
Anobium punctatum - small wood beetle
Development cycle : Adults come out of mid-May wood at the end of August. They live from 15 to 30 days and do not feed. after mating, the female deposits 20 to 40 eggs in the wood slits. The larval cycle lasts from 3 to 5 years on average. the adult exit holes are round, from 1 to 3 mm in diameter.
Xestobium rufovillosum - large wood beetle
Development cycle: Adults come out of wood from April to May and live 9 weeks. after mating, the female deposits a hundred eggs in the slits and roughness of the wood. the larval cycle lasts from 1 to 10 years, in a wood already infested by rotten mushrooms. galleries dug by larvae are round. The exit holes are round, from 2 to 4 mm in diameter. Vermoulure has a lenticular shape.
The adult wood beetle penetrate the houses while flying. the female lays on the wood in the summer. the young larva enters the wood she will dig to feed herself. Arriving at the adult age, she'll come out of the woods.
Its larval cycle is very variable, depending on the humidity, temperature and nutrient quality of the wood. it can last between 1 year and several years.
The adult life of the wood beetle is only dedicated to reproduction. She doesn't feed and lives a few weeks, just the time to reproduce.
The wood beetle can attack many woods such as cherry, charm, alder, poplar. It particularly tackles old woods or woods previously altered by mushrooms but rarely in the heart of oak or pine.
The wood beetle cannot live in a constantly dry atmosphere (at certain times of the year, these insects are called every day at the same time by striking from their head scrambled blows on the wood. These noises, audible from the outside, went to the wood beetle, the nickname of death clock.
Even if the calf will not destroy a piece of furniture or a floor quickly, it must be known that if you let it proliferate, its number may be multiplied by 10 years ! !
For all diagnostics and treatment method, you can read our file on this subject.
Small pieces of wood (of course not your cart)!can be put to the freezer.
If possible, try to reduce the moisture in the wood (drying, ventilation, heating).
Depending on the regulation, 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 the 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 a wood beetle is an insect. and to kill an insect, an insecticide is used to belong to TP18.
So you can use a natural insecticide to kill the wood beetle. This insecticide will not have any wood protection function, unlike products for wood processing. But he'll get rid of the wood beetle.
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 the calfskin, is to penetrate the insecticide into the holes made by these insects (seringue, spray, sponge, serpillère).
For this, 3 products may be suitable
1 - Our insecticide 4j All insects(4j to 5%). This 500 ml spray will allow you to process about 5 m2. for larger surfaces, use this same product but under itsconcentrated form. then you will make a 5% dilution with water. It is important to know that this product, based on vegetal pyrethra with a rather short remanence. It will therefore be effective in early curative action but not long-term curative action. from the moment the insect will becontact with the product 4j, it will die instantly (the neurotoxic effect of the pyrethre). the difficulty remains to touch these insects often refugees in the heart of wood parts. 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.
N.B.: It is obvious that if the wood beetle 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.
Frequently asked questions about the wood beetle
R: It depends on the surfaces to be treated. if it is a small closet you can use for example our aerosol all insects Ecodoo or our 4j spray diluted to 5% for large surfaces. otherwise, you can use our pure 4j that you will dilute with water. If it is for a parquet, the most effective it is to wash on the ground with our 4j if it is a piece of furniture, 4j spray on the internal walls + possibly treatment of the holes to the syringe on the external face.
R: You can use our 4j insecticide ready for use or pure to dilute, for use it depends what you want to treat if it is a piece of furniture (if waxed furniture: treatment inside with spray + if necessary inject with a syringe in the holes on the outside side) or other ...
R: It has been tested on many insects but not yet on the wood beetle.
R: You must treat the inside of your wood to the brush or sprayer with insecticide (2 layers to 24 hours interval) if you have the courage you can also inject insecticide into the outer holes (seringue).
R: All liquid insecticides will close the case, the furniture must be processed inside the brush or spray; provide 2xcouches at 24h interval. on the outside if you have the courage and if it is strongly reached you can inject insecticide with a syringe in the holes.
R: Wood beetle or capricornes? in both cases you can use our 4j insecticide, but if the galleries are deep you may be required to process your beams by injection.
R: You can use our insecticide 4j to 3% but to be effective it will have to bring the product into the holes made by the wood beetle.
R: I don't know any essential oil that could kill or even get away from the calfs, but why not, if you know about it I'm interested.
R: We have an insecticide that can be used to treat furniture but it is totally different from natural xylene and not water solvent synthesis and non-contact oil distillate and non-neurogenic. 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.
R: The same reaction as if you wash your parquet with water !
R: If it's a water paint you can dilute to 5% of 4j with 95% paint but we never tried this process. Personally I would treat the wood to the insecticide I would let dry and paint on it after.
R: For example, you can use our insecticide "Insecticide All Insects" (4d to 5)%, but it is necessary to treat inside otherwise the wax will prevent the product from entering the wood.
R: We usually treat only the wood reached it is not necessary to treat healthy woods.
R: We have good results with our insecticide "all insects" compared to the wood beetle in general eat only wood or some of the paper but not wool carpets. You must probably have holes in your parquet if it's calf, if that's the case you have to start by treating your parquet by getting the insecticide into the holes of the parquet.
R: In wet wood we find mainly calfskin especially if it is small holes with a slight sawdust.
R: Your problem is complex since the shinings are already in the wicker, so the treatment product should come in contact with the insect, in this case the most effective would be to soak all your baskets in an insecticide bath but I don't know so technically it's feasible. l
R: Insecticide all insects Ecodoo is based on vegetable pyrethra and essential oils. This product is only dangerous for cold blood animals (fish, snakes,). but not for mammals.
R: Small holes in wood with sawdust it is likely that it is from the wood beetle, it corresponds since they reproduce in July-out when it is hot if your wood is waxed it will have to process holes with a syringe !
R: Small hole round in a parquet it is likely that this is from the wood beetle, are you sure that this hole is recent? summer is the time when the wood beetle reproduce, so it was all possible.
R: You don't have to read well: you drill holes when you inject into beams but not in parquet, for the furniture you inject insecticide into the existing holes with a syringe, for the parquet you can treat with syringe, brush, roller or serpiller. I think the wood beetle should not like the essence of turpentine but I'm not sure it kills them !
R: Wood processing products belong to the TP8 class and since the new regulations, natural insecticides are no longer allowed to treat wood. wood bliss is not an insecticide, it mineralizes wood theory.
R: To be effective, the product must be able to penetrate the wood, the pistol, which is very effective, contains paraffine which is rather a heavy product and I am not sure that it will well penetrate the wood. we begin to find on the net wood processing products based on margosa. I'm not sure it's very legal since margosa's extract is tp19 but not Tp8! margosa is interesting in the treatment of plants and it is likely that it also works in wood. We market margosa extract on our site that will have this repulsive action
