Corporals in your house?

The cloak of the houses is a flat-shaped beetle insect, of brown colour and can be measured between 1 and 2 cm. You often talk about termite, a pest of your woods, but the capricorne is just as problematic when it comes to your woods of charpente and carpentry. Indeed, this xylophageal insect will come to lay between 20 and 80 eggs. These are larvae that will then come to feed themselves by devouring the wood and digging galleries. The capricorne mainly attacks resinous woods such as fir, spruce, melèze or pine and digs galleries in the carpenters, parquet, burglary and all carpentry at 6 to 8 millimetres a day. It is therefore a real danger to your homes. You will see their presence by the holes on the surface of the oval shaped wood and 8 to 10 millimetres wide. You will also see dejections from a light beige and you will hear rumours of snacks. Not at ease in the air, the adult capricorne is innofensive and flies only on a small distance. If you see all these signs, then it\'s time to think about treatment to make them disappear.

 

Why natural insecticides?

Finishing with the capricornes is one thing, but if you could also preserve your health and your environment, wouldn\'t it be better? Did you know that some conventional insecticide particles remained for several months in your processed parts? Fumigen is the worst because the particles fall on all objects, textiles, parts of the room. Unless you carefully wash each item, you will find yourself inevitably with chemical substances. Opting for natural insecticides will allow both to get rid of capricornes but also, by the composition of our products and their low remanence, to continue living in a healthy environment.

Who's the capricorn houses ?

HYLOTRUPES BAJULUS - capricorne des maisonsLatin name: Hylotrupes bajulus
Order: Beetles
Family: Cérambycidés
Adult size: 10-20 mm
Size of the larva: 20 to 25 mm
Location: in wood
Period: all year

It is an insect that is found very often in nature. it feeds exclusively wood, and more precisely resinous wood. among its predilection essences are the marine pine, the laricio pine, the autriche black pine, the sylvestre pine, but also the melze, the epicea, the fir. and the list is not exhaustive!

It is very well suited to the woods, and as much of the so-called woods, hence its taste for the carpenters, and occasionally for elements of less importance, such as the oilseries of your home.

The adult insect having a very short life (about 1 month) and not feeding during this period (reproduction) is the larva, which, through its development and years will do the most damage. it looks like a large white worm measuring 20 to 25 mm long, the aforesaid part of which is enlarged and flattened.

  

What you need to know about the capricorn houses

HYLOTRUPES BAJULUS - capricorne des maisons The cloak of the houses mainly attacks the well-dried, dead or construction resinous woods such as the larch or the spruce, but also the oak tree.
The larva perceives a network of galleries whose walls are finely carved by its mandibles.

As long as larvae can feed, the capricorn will remain in the woods.

Apart from the characteristic noise of larvae gnawing wood, it is difficult to detect its presence. The identified holes may also be of excellent presence index, but they are never numerous, and not always visible (behind your insulation for example). the discovery of the insect, dead or alive, is also possible, but not less random, especially as the insect is small. Finally, if you find sawdust, look closely as it is not uncommon that its compaction in the very superficial galleries splits the residual wood film, hence a revealing flow. Note also that any wood stock, even very localized, is at least suspect, and a survey is required ( knife point, or small screwdriver blade for example).

Not loving the cold and humidity, it is easier to find in the heated premises.
The capricorn does not attack the heart of the wood, it is only content with the (more tender).

  

 Hylotrupes bajulus - capricorn housesHYLOTRUPES BAJULUS - capricorne des maisons

Development cycle:Adults come out of mid-June wood at the end of August. They live from 15 to 30 days and do not feed. They will devote this time only to reproduction. after mating, the female deposits between 40 and 100 eggs in the wood slits. The larval cycle lasts from 3 to 5 years on average. but the duration of larval development depends on the nutrient qualities of wood, ambient humidity, and of course temperature. the galleries dug by the larvae are oval and striated by their mandible shots. the adult outlet holes on the surface of the wood are oval shaped (elliptical) about 6 to 10 mm long.

Generations often follow on the same woods, especially since occasionally the capricorn can reproduce without leaving its galleries, which obviously adds to its discretion, and especially to its nuisibility.

 

Some differences with the oak capricorn

 Hesperophanes cinereus - oak capricornHesperophanes cinereus - capricorne du chêne

There are more than 25,000 species in the family of cerambycidae called vulgarly capricorn. only a representative can actually be considered harmful to our homes: the capricorn houses. However, it is often confused with other species of this family, especially with the oak capricorn (cerambyx cerdo or Hesperophanes cinereus). Also known as a great capricorn, the oak capricorn is an insect protected by a ministerial decree dated 22 July 1993 and, also at the European level, via annex ii of the berne convention and iv of the habitat directive. Therefore, it is forbidden to fight chemically or even ecologically against the oak capricorn. it is much larger than the capricorn houses.

As its name suggests, this capricorn is found mainly within the old oak trees and sometimes in the old chestnut trees. it is not present in the houses, except if it has gone astray. The oak capricorn only rarely leaves the tree from which it was born. In any case, this insect is no danger to your home.

Development cycle:Adults come out of wood from May to late August. They live from 15 to 30 days and do not feed. The larval cycle is usually shorter than for the capricorn houses (2 years or older). the degraded woods have the same aspect as for the latter, but the galleries are larger and the more numerous exit holes.

  

How can we fight the capricorn houses ?

HYLOTRUPES BAJULUS - capricorne des maisons

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 wood processing products, cypermethrin is found with a solvent (white spirit, citrus, water, ...). whether with or without odor, these treatment products containing components of oil origin are not very healthy in a place where you live !
But a corporal is an insect. and to kill an insect, an insecticide is used to belong to TP18.
So you can use to kill the capricorn a natural insecticide. This insecticide will not have any wood protection function, unlike products for wood processing. But he'll get you out of the cloaks.
Although it may seem obvious, do not try to treat a waxed, 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 capricorn, is to penetrate the insecticide into the holes made by these insects (seringue, spray, sponge, serpillère).

 

3 products may be suitable for this purpose :

- Our insecticide 4j all insects (4j to 5%). This 500ml vaporizer will allow you to process about 5 m2. for larger surfaces, use this same product but under its concentrated form And 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 quick curative action but not in long-term curative action. from the time 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.

 

- 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.

-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 diatomy 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:

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

2 - 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.: Capricorn is part of xylophageal insects. for all diagnostics and treatment method for this insect family, you can read our file specific to xylophages.

Frequently asked questions about the capricorn

Q: We have a section beam 200*200mm of 7ml fir that is apparent in our living room. (in 2007). it turns out that it is infested with capricorn on the abier in part horizontal. (not every day). Do you have in your product range a curative insecticide that I could apply on the surface? I can hardly reach the top of the beam (10cm from the ceiling), but I can nevertheless make holes to promote the penetration of the product. Will a surface product be sufficient ?
R: You can use our 4j insecticide diluted to 5% but to be effective, the product must come into contact with the insect either by saturation of the wood or by injecting the product into the wood. In the first place, it will be necessary to bring down all the garbage that is damaged or that is no longer holding.

Q: I have to deal with 145 m2 of new burglars in my house. They're infested with capricorn. How should I take it ?
R: Besides the new biocide regulation, our products can no longer be used on xylophages but whatever insecticide you will use, we need to treat raw wood (non-painted or varnish) to the wood saturation brush with 2 treatments at 24 hours interval. Considering the low thickness of the wood (1cm) this should be sufficient.

Q: Which product may be used to destroy the cloaks? and has what dosage is available and preferred?
R: Our products are not approved for wood processing.

Q: I own old buildings in the alps of high provence. 3 days ago and for the first time I saw insects attacking poplar beams, large piles of small shavings on the ground, noise of flying insects and we hear the wood snoring. Three weeks before nothing, I'm very worried, this roof is 500 m2 and I wasn't seen the uncommon carpentes.
R: It could be capricorn, it's the time they reproduce .

Q: Against xylophageal insects, can we treat just some of the woods of the house (one piece only) or should we absolutely treat all the woods present ?
R: Generally speaking, we only treat wood to reach. it is not necessary to treat healthy woods.

Q: The cart of my house lets appear sawdusts, termites, vrillettes or capricorn? I don't know how to differentiate them, what product to use, if need of injection in the heart of the wood which tool to use, I am very allergic to xylene
R: Probably capricorn houses, may be vrillettes, but in general they are found in furniture termites do not leave sciur. Injection treatment requires equipment that you can rent (compressor, nozzle, ..). our 4j insecticide is a priori efficient on this type of insect although it is not registered for wood processing.

Q: A tree in the garden with inside the capricorn larvae. I cut it, but in the strain, there's more. which product you buy ?
R: Our diluted or pure 4j insecticide will be perfect, but this product does not support the rain. Simply fill each hole in the strain to kill them and protect the whole by a tarpaulin the time the product acts. Moreover, our 4j insecticide is not registered for wood processing.

Q: She's a friend who told me your site because I live in an old house or the capricorn make damage that starts to be important. it seems that there are other insects that they make holes in the exposed but smaller beams. which products can I buy from you to end this problem? how the application is done. I brought in a company that made me a quote of...1500 euros! I find it prohibitive !
R: Before you answer, I advise you, if you have not already done so, to visit our special xylophages folder on our site. You should find some of your answers. for treatment, prefer the margosa extract (excellent repellent) that you will dilut with water and a disinfectant. 1500 euros? or they are unintentional people or there is a lot of work. This represents about 3 working days + the products.

Q: I'm interested in the treatment of the cloak for buildings, the best solution is the pure can ?
R: Pure insecticide is more economical than ready to use and mainly on shipping costs (especially when you need several litres). as it is a product that keeps and can be used on all insects, I think it is more interesting in pure than diluted. However, our 4j insecticide is not registered for wood processing.

Q: I bought a shepherdac house 24; the cart (50m2 of roof) has been reworked recently, but on some old preserved rafters I suspect the presence of capricorn. would your insecticide be effective and how should it be applied? How much? at what price? What's the matter with these precautions ?
R: Since the new insecticide regulations, hormised boron, no natural product is approved for wood processing.
To fully understand, capricorn, (such as vrillette, termite, brown lyct) is an insect that can be eliminated with a natural insecticide (classified TP18 in biocides) when treating the insect in question in a room of the house or when it is visible and placed on wood. However, when it comes to wanting to eliminate the insect in question in wood, and that's your case, we're talking about xylophageal insect treatment (classified TP8 in biocides). we currently do not have a natural product classified TP8.
Regarding the use of insecticide 4j, we know that it is effective on capricorn. except that this product, based on natural pyrethra with very short remanence. it is therefore effective in quick curative action yes but not long-term curative action.
However, in your case, we can refer you to margosa extract (classified tp19 (repulsive) in biocides.
The main property of margosa or neem is to make unfit for insect consumption all treated surfaces, insects must then either leave the area treated in search of food or die of hunger.
Thanks to its wide spectrum and long-lasting action, margosa is effective in most infested locations. spray or injection application. bio insecticide blocks larvae development, disrupts food research and sterilizes adult insects. "
Treatment to be performed vaporization on wood with a concentration of 2% in preventive use, at 4% in curative.

Q: What is the product that treats the capricorn installed in the charpente wood ?
R: Following the new regulations, except boron, you no longer have any natural product allowed. You have to see the side of the permithrine! or with our margosa extract that has very strong repulsive properties.

Q: i can contact you because I discovered my wooden staircase with lots of small holes and yellowish sawdusts on the stairs..I don't see any insects! my house is old and when you descend into the cellar the stairs of the floor is apparent but the holes are on the steps seen from the house and seen from the cellar so on both sides; They are small sizes but very scattered and we see each day yellow sawdusts...I don't know what to do I'm afraid it's spreading everywhere! I have the house since 2006 and this is the first time that this happens but I think it can come from an old firewood that I brought back to my cellar because when I put this firewood under my fireplace, there were similar sawdusts! I would like to have information on the problem and if you can bring me a solution to make the problem go away! Thank you in advance.
R: Small holes in wood with sawdust, it is likely that it is from the vrillette, it corresponds since they reproduce in July-out when it is hot. If your wood is waxed, you'll have to process holes with a syringe !

Q: I want to kill capricorn larvae in the pine boards that are used as dressing on the walls and ceilings of my home. is this possible with your products? with what implementation ?
R: Except boron, no natural product is approved for wood processing. You must see on the side of the canhrins or with our margosa extract, excellent natural repulsive.

Q: Thank you for your quick answer. well by pushing my exploration further, there is a big hole, but several little ones and there on the parquet and the folds. I had not seen them before and yet I am very observatory, so I think they are quite recent, but it is true that we have changed the layout of the furniture, and thus these parts have become less visible. I read your article on the vrillette on your site, you recommend drilling holes and injecting an insecticide? in your range, which would be the most suitable? organic terebenthine gasoline could not be enough, would it?
R: You shouldn't read well. We drill holes when we inject into beams but not in parquet. For furniture, insecticide is injected into existing holes with a syringe. For parquet flooring, we can treat syringe, brush, roller or serpiller. I think the vrillettes should not like the essence of turpentine but I'm not sure it kills them !

Q: i just discovered capricorn in the beams that you advise me to get rid of them?
R: For 1 year apart, boron plus no natural product is allowed for the treatment of wood against xylophages insects. On the other hand, margosa extract is an excellent repellent. the active principle of this treatment is based on margosa oil (indeed oil). thanks to its wide spectrum and long-lasting action, margosa is effective in most infested locations. spray or injection application. bio insecticide blocks larvae development, disrupts food research and sterilizes adult insects. You will find margosa extract on our site, to use diluted with water at 90.%.

Q: Hello, I found the presence of capricorn in my firewood reserve ( oak logs). Is there a risk for the carpenters in the house because sometimes I leave the basket of the bushes next to the chimney between two flares? How and with what?
R: I don't think there's any concern about your house cart. We observe the oak capricorn between May and August because they come out of the wood to go reproduce. It is therefore quite normal to observe them at this time. the risk of contamination of your mouths near the chimney to the tank of your home is very low. Whatever it is, you must remain vigilant and control the presence of xylophages under the roof from time to time. As long as they settle there, larvae begin to nibble the woods. concerning methods of control and prevention, I invite you to read our dossier on this insect. There you will find a lot of answers.

Q: Can you tell me how to eliminate the insect the capricorn in my outdoor stored firewood?
R: The difficulty of insecticide treatment in a pile of outdoor firewood is to be able to apply the product. Since the bushes are piled on each other, it is not obvious to apply the products (whatever they are). The insecticide we sell is a contact insecticide. That is to say that it will only take place if you can contact the insect, its larva or its egg. the other difficulty lies in the fact that it is a xylophageal insect. It is therefore mainly located inside the wood parts, since it feeds, and therefore hardly accessible. the 4j insecticide we sell will have no wood protection function, unlike the targeted wood treatment products (e.g. xylene). On the other hand, it will rid you of capricorn, from the moment your treatment is well done and methodical.
To be effective treatment must be done on raw wood. The solution, a little long and tedious but effective to kill the capricorn, is to penetrate the insecticide into the holes made by these insects (syringe, spray, sponge, mop). regarding the use of our 4j insecticide, we know it is effective on the capricorn. However, this product based on natural pyrethra with short remanence. therefore, it remains effective in early curative action, but not in preventive action. a second product will also yield good results, and there, on the contrary, with a much longer remanence. This is the margosa extract. the main property of margosa is to make unfit for insect consumption all treated surfaces. Insects must then either leave the area treated 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 to be carried out in vaporization on wood and by injection in holes with a concentration of 2% in preventive use, at 4% in curative. a use diluted with water according to recommendations.
