Anthrene is a small insect of 3 to 4 mm that resembles a bit of a coccinel (same family). In the spring, it kills flowers on the outside and also benefits from entering our homes by the open windows. Once installed inside the females can lay. As often, these larvae create damage. They attack textiles by nibbling them as the mite knows how to do it. You will know that anthrenes cohabit with you as soon as you see empty mues (small balls full of hair resembling plush) or you will find your clothes with large irregular holes. They exist natural solutions to fight anthrene. We offer Penn\'Ty Bio a range of preventive and curative products against this insect.


Why natural insecticides?

Ending the anthrene 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 anthrene but also, by the composition of our products and their low remanence, to continue living in a healthy environment.

What you need to know about carpet beetle

L'anthrèneA beautiful season, this insect lives on the outside, damaging flowers (especially ombellifers and spirées). it lays in the bird's nest, its larva eating various dried organic waste.
There are several possible sources of infestation: a bird's nest, an organic isolation (wheat, felt, hemp). Attention also to cut flowers that can help carry these adult insects in homes.

Do not confuse the adult carpet beetle with a small cocial, even if both are part of the order of the beetles !

The larva lives in the dark (below of carpets, cupboards, cupboards, drawers, etc.) and its diet is very varied from the moment it is organic. It is mainly found: starch, vegetable spices, chitine, collagen, keratin.

With this type of feed, this insect is particularly daunting. It is capable of attacking all organic materials such as wool, leather, silks, dust, cotton, hair, hair, animal hair and feathers, film, insects and dead animals, carpets, furs, horn, insect collections, naturalized animals, etc., and of course, textiles in which it makes large irregular holes.

Oeufs d’anthrèneAttention only one female of carpet beetle can cause enormous damage.
In the case of insect collections, it is mainly the smell of stored insects that attract it. she will lay her eggs at the closest to the food, in the window if she can or in front of where the smell comes from. Once hatched, the larvae, extremely small, will be able to penetrate the place. if this window is waterproof, it is likely that they reproduce inside until exhaustion. food.

Whether it is museums, furniture or carpets, it is the olfactory receptors of the carpet beetle that guide it to where the food will be abundant for the larvae it will lay. like the mite, only the larva is responsible for the damage caused in your home. in order to disrupt the olfactory receptors of the adult carpet beetle, the best prevention is to mask odors. It is for this reason that our grandmothers deposited in the cabinets of the naphtaline balls (polycyclic aromatic hydrocarbon) now banned for several years.

The carpet beetle, unlike the mites, leave no canvas. On the other hand, excrements (size of a grain of salt) or exuvies (old mues of larvae) may not be confused with living larvae.

The larva is about 4.5 mm and resembles a small white worm whose entire body is inherited with dark hair touffs, slightly longer on the sides. these hairs can cause allergic skin reactions. It is therefore best not to manipulate them.

Jeune anthrèneFor several years, more and more people have been telling us the presence of antirene in their home. If it is very easy to treat a closet, it is more difficult to treat a whole house. But, reassure yourself, it's possible. It just requires a little more time, courage and method.

Life cycle of the rug carpet beetle

Mating takes place immediately after adult life begins. Carpet beetle females can lay between 20 and 200 cream-colored eggs, 0.5 mm long and have projections similar to spines at one end. over a period of 2 weeks, these eggs are deposited in suitable cracks or cemented with sticky secretions on a potential larvae feeding site. After 2 to 4 weeks, eggs hatch, giving birth to characteristic larvae, velues and trapes. Once mature, carpet beetle larvae measure between 4 to 5 mm, are brown and have 3 tufts of golden hair arranged in pairs on the posterior segments of the abdomen. their short legs with 5 articles are well developed, with a unique claw on the terminal article. carpet beetle larvae avoid light and roll into ball when disturbed. the duration of larval life depends on the temperature, humidity and quality of the food. Defiled foods are most of the time their favorites. During this period, larvae go through at least 6 mues, but the more larval they remain, the more mues the number increases. Nympha transformation takes place in the last larval envelope. the nymphase stage ranges from 10 to 30 days. adults live between 2 and 6 weeks and are able to fly to the flowers on which they feed and seek weighting sites.

How do you protect yourself from an carpet beetle invasion ?

l'anthrèneYou can prevent infestations by regularly inspecting the places sought by the carpet beetle and by adopting good cleaning habits, including by regularly venting the places closed (plates, drawers, etc.). The sealing of cracks and cracks can also be a good way of prevention.

It is also recommended to remove from buildings the nests of bird and abandoned insects.

It is also necessary to examine the presence of these adult insects on the cut flowers reported at home. Do not hesitate to shake and move the inside of your closets during the summer to disturb the squatters, because this is the time they lay.

They are olfactory receptors that guide the insect and can drive it where it is not desired. The best prevention therefore consists in masking emanations likely to attract it. what the naphthaline balls used by our grandparents, or the lavender bouquet still used today against the mites.  anti-mite bags will work perfectly well to push back the carpet beetle and prevent them from installing in the drawers or cabinets. Just like the diffusers, hooks and neem oil spray to apply directly to the clothing to be protected (see below). in general, all our products against the mite of clothing will also work against the antirene.

And the essential oils in all this? THE essential oil cedar atlas organic has really interesting insect repellent properties and will therefore be an excellent repellent against carpet beetle. In addition, it will leave a pleasant woody smell in your closets. just drop a few drops of this essential oil on a porous stone (or on our clay stone diffuser), and place it in your drawers, dressers, wardrobes and wardrobes. It is also possible to make small cushions that will remove the carpet beetle by imbibating them with some essential cedar oil. Consider renewing the oil regularly and especially in September, when the eggs hatch! but be careful, essential oils will only have a repulsive power against carpet beetle. Keep in mind that they should be used in prevention and not for curative purposes.

How to eliminate carpet beetle ?

The first thing to do is to stay calm and proceed in order. the following information is to be modulated according to the gravity of the attack. Below we offer a method when you are in the scenario of a proven invasion.

1. empty your closet completely

2. perform disinfection of clothes: 48 hours to the freezer for all objects supporting the cold or at a temperature of 70°C. we can also deal with the spray mites textiles Aries all the clothing you need or those you don't need right now (winter/summer tumble, etc.). this spray composed of neem oil, although it is targeted above all against the mites of clothing will also act against carpet beetle.

Once the clothes are processed and to be really quiet, you can lock them in plastic bags or a totally hermetic cover.

3. for clothes, you also have the solution to put them in a trash bag and fill the volume of air with insecticide. for this, it is best to use insecticide Ecodoo Based on alcohol and essential oils. close the bag and let the insecticide act all night.

4. pass the vacuum cleaner in all the kidneys and mainly the dusty ones and this in order to remove, eggs, larvae, insect corpses and organic debris that can feed the carpet beetle.

5. treat all surfaces, corners, slots, cracks, etc. with insecticide 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 it concentrated form and you'll make a 5% dilution in a sprayer.

6. Put the clothes back.

7. to finish and to disrupt their receptors, we have to install products that smell good but that will mask the odors. for this, we offer 2 references. don't surprise you that they are to the mites of clothing. It works perfectly also for carpet beetle :
a- Lot of 10 packs of antimites clothing (contains essential cedar wood oil, excellent repulsive) packed in a welded aluminium bag, to be placed on shelves.

b- Protection Anti-mites textiles aries contains 2 diffusers that can be hung to a closet.

8. do not forget to pass the vacuum cleaner at least once/week and eventually take advantage of it to give a little aerosol shot insecticide Ecodoo Or flying insecticide Aries before closing the closet.

9. to be sure to put all chances on its side, you can use once the treatment of the 4J insecticide performed, the fogger habitat Biovétol, an automatic diffuser composed only of plant-based assets (exist in 3 different formats).

Do you have a big surface to treat ?

For the treatment of a complete dwelling or large surfaces like carpet, carpet,. we recommend that you equip a sprayer type garden and d'insecticide 4j concentrate. make your own preparation by diluting insecticide at 5% with water. for information, a 4j bottle concentrated 250 ml in 5 liters of water allows you to treat 50 m2.

To be really effective, it will be necessary to treat in addition to surfaces, all dark places like behind folds, slots, grooves. for this type of treatment, we can use the bomb insecticide all pests which is particularly effective on larvae and eggs.

Here's what an carpet beetle looks like in motion

Frequently asked questions about carpet beetle

Q: I have some questions about the use of your products on the antirene.
a- for the aerosol Ecodoo All insects, how much should I put for a trash bag of 30 litres (3 sprays?)
b- Does the smell kill – does it kill the carpet beetle or simply make them flee ?
how long does the eggs develop ?
d- what is their time of resistance and also that of carpet beetle, time of life locked in a plastic box, I now lodge my clothes there. I then spray two or three jets:

R: The answers in the order:

a- everything depends on the time spent pressing the button. based on manufacturer information: 30 seconds in a piece of 12 m3. So, if you spray for 3s or for 1 volume of 1.2 m3 you are for a bag of 30l to 40 times the manufacturer's dose, I think it is largely enough.

b- it's not a repulsive but an insecticide. saturating the air of a bag requires insects to breathe insecticide and die very quickly.

c- about the rug carpet beetle (the verbasci): 40 eggs that hatch after 10 to 20 days.

d- a larva locked in a hermetic box in which insecticide is sprayed Ecodoo dies very quickly. No insecticide, no idea. If the box is completely waterproof, the insect will die by asphyxia but not hunger. they can also die of thirst if the air is dry. When with the eggs, they will resist to the outbreak and do as the larva.

Q: I would like to treat my parquet (rains) against carpet beetle. 1/ it is an old and beautiful (!) parquet in vitrified oak. Can I apply your products without deteriorating my parquet? 2/ What is the protocol for carpet beetle ?

R: If your parquet is vitrified and not waxed, there is no problem, but treat preferably with a jet sprayer in the groove (well wet the bottom of the groove) since it is not worth treating the parquet by itself, insects will not be in. If you have insects, larvae or eggs in the grooves, they will be destroyed by insecticide.

Q: I'm apparently confronted in my apartment with a small family of anti-Christmas. You indicate that you can get rid of it with insecticide. but, among all your range, which one is most recommended for this kind ?

R: You have the choice it depends on where they are located, you have several insecticides on our site and that you will find in various packaging, the 4j and pstal are effective on eggs and adults but only if they are affected by the product. the aerosol Ecodoo is a pyrethre-based neurotoxic that does not kill eggs but can kill adults who breathe the product.

Q: I have my clothes that are full of small holes but not wool clothes that are cotton. What insects can it come from? with which solution can I treat my clothes. Can I have a cat from my animal ?

R: Holes in the clothes, you probably have mite or carpet beetle. If it's big holes, it's certainly about the carpet beetle.

Q: do you have a product that can replace naphtaline for insect boxes? it's not about mites of clothes but boxes of collectible insects, before i put a piece of naphtaline in a corner, but since it's not for sale, insects are rode by the bugs.

R: it is probably the carpet beetle of museums that are frantically found in in insect collections. These insects are attracted to the smell of corpses. naphtaline is only there to mask the smell, which usually works well. we can replace this product with our anti-mittee packages based on essential cedar oil that smells strong but lasts less long (about 1 month). Before removing insects, you have to destroy larvae that are probably installed in your collection. our ecodoo insecticide bomb based on pyrethre and alcohol (don't wet and dry very quickly) should arrive without any problem.

Q: For 1 week I have beasts resembling coccinels that climb on the side of the windows. they have on each side at the level of their mouth 1 white croc (I don’t know the name please excuse me) I also hung clothes out and found 1 cotton sweater with holes. I found one in the dining room that I have to do. Thanks for helping me get sick, I’m afraid I’m in the house. I don’t even dare to aerate the house. I put a lot of insecticide around the windows and in the house. Every day I find it I don’t know if there’s a report but I have small holes in the garden. Is that their nest? I don’t know if I have to put crawling or flying insecticide.

R: I think your beasts are carpet beetle.

Q: I would like your advice for a product that would eliminate the carpet beetle and the mites of clothing; because I don't know which one of them makes holes in my clothes and especially for some time those I wear to sleep. It's been going on for years, I've seen the butterflies before, I've called on an exterminator. It stopped to start again months later. For more than two years, I don't see any more butterflies but the holes in my clothes, up to the belly. I continually savor from the neem oil diluted with water, in my drawers, on the mattress and wardrobe. We're a family of four and only my clothes are attacked and it's the night I sleep! Would you have one or more products to advise me and make your delivery to the quebec, canada. ?

R: If you see flying butterflies, they're mites. If you don't see anything flying, it's probably carpet beetle, the adults resembling brown cocials. Besides, the hole description matches. You say vaporize neem oil with water, but, is this oil cosmetic or insecticide? If it's cosmetic, I'm not sure it's very effective and in any case, the neem is not an insecticide but rather a repulsive. As for the mite, the larva makes holes and hides the day. According to our customers, it's very difficult to get rid of the antirene. 5% insecticide is very good to treat surfaces, aerosol Ecodoo to treat closed volumes, pistol to treat slits, cracks and other recoins, anti-mite Aries to treat clothes. all these products are effective on mites and carpet beetle. We deliver to the canada without problems.

Q: Hello, carpet beetle infested our house. larvae seem to be lodged under our floor between the lambourdes and malgre 2 fumigenes at 4 weeks interval, there are still adults in the living room near the folds. we would like to find 1 product that could kill these larvae and adults when they come out of the floor at the folding level because we cannot have access under the floor. Do your products such as 4j or pistal exercise their contact action over several days or only for a few minutes after application? We have 1 infant of 2 months and 2 children, are these products harmful to them? must leave the premises after application of the product(s) indicated and if so, how long? Thank you for your opinion. cordially

R: Hello, the difficulty of treatment under the floor is actually being able to reach the larvae. our insecticides are many contact insecticides. On the other hand, they will not have remanence for several days. We wish to stay on products whose composition is as natural as possible. Therefore, you will not find synergizers or additives to enhance the power of the asset or increase the remanence of the product. the 4j, as the pestal act immediately (or almost immediately) by contact with the larvae, eggs or adult insects but degrade from them even in a few hours (depending mainly on room temperature).

Compared to the product's nocivity, there is no concern. nothing to do with the smokes sold in the trade. the pyrethra degrades alone and disappears in a few hours. it can stay according to the product used some traces of potassium soap or paraffine (which gives the asphyxiating effect vis to larvae and eggs), but they clean without any problems with a sponge or a humidified sponge. Moreover, the advantage of these contact insecticides (unlike a smoker) is that one can aerate during treatment (and after) without worry. the smell of pyrethra and the complex of essential oils that can give a slightly strong smell.
However, by caution, because the pyre may be natural, it does not have any harm (especially when it is handled in its concentrated form) it will be preferable to leave infants, children and cats in another room than the one treated. The advantage is that 4 to 6 hours after the treatment, everyone can reinvest the treated part.

Q: Hello, I would like to treat my apartment (26m2) against the carpet beetle. I already bought some product Ecodoo to treat all my clothes, bought anti-mites to stick in my wardrobe, but I would like to treat my apartment fully to be sure to get rid of it. I have two cats this weekend they go to my sister's house so I can do all this quietly. To treat the whole apartment I need to buy the 4j insecticide concentrated in 125ml vegetable pyrethra ?

I intend to spray everything on Saturday morning, let it work and come back on Sunday afternoon to wash everything and aspire. Do I have to take a bleach after? Or should I just aspire? Is that dangerous for my cats ?

R: Insecticide 4j concentrated: yes. against carpet beetle, we predict a dilution of this product to 5.% a bottle of insecticide concentrated 125ml, once diluted in water to 5% will allow you to cover about 25m2. the bottle of 250ml concentrated, the double, or 50m2, etc. your apartment making 26m2, a bottle of 125ml concentrated should therefore be able to cover the apartment for treatment. Attention, however, to also calculate the inner surfaces of cabinets/placards. these surfaces will increase the treatment area to be expected.

Once the treatment is done, the pyre will act quickly on all insects in contact with the product, including on eggs and larvae. Insecticide 4j is a contact insecticide. That is to say that it will only take place if you can contact the product with the insects. This data is important. The more you treat surface, the more you increase your chances of destroying them. favor the treatment on the inside surfaces of cabinets, convenient, drawers, having taken care to empty the spaces. also target surfaces or you have observed, soils and carpets, etc.

It's not necessary to pass the bleach after. a clear water surface leaching can be done to remove the small potassium soap film that the product could have deposited. in order:
- a big vacuum before treatment
- treatment with insecticide 4j
- a new one, a big vacuum blow
- then soil leaching.

4j treatment should be done in the absence of animals. the product containing pyrethra, it would risk getting on their feet and then ingesting it by making their toilet. However, if the treatment is done on Saturday morning in the absence of cats. you can come back with them on Sunday without problems and reintegrate them into the apartment. The pyrethra will have dryed and deteriorated. There will be no more risk to animals.

Q: I recently ordered to fight an carpet beetle infestation in my apartment. I alternated this weekend with the 3 products, namely 4j, Ecodoo and pistal. I wanted to know if there was a counter indication to use these products frequently and in our presence. Last weekend, I sprinkled the folds with and we were absent from the apartment.

Is there any risk to a 3-year-old?

I ask you these questions because although reassured by the explanations that your site contains, I start on the other hand to be worried about what I read on many forums about the fact that insecticides must be avoided at all costs. and to finish, I observe a very slight decrease in the number of observed antirehenes but nothing blatant. Do you have any testimonies from customers who have come to the end of these bugs? And if so, at the end of time? Thank you very much for your help. I'm a little desperate.

R: Most insecticides in trade are composed of synthetic insecticides (organo-chlorines, carbamate, organos-phosphores or pyrethrinoids). There are indeed many studies that have demonstrated the adverse effects of using this type of insecticide on our health and the environment. the insecticides we sell are exclusively composed of vegetable pyrethre (which is therefore not a synthesis). we have recently excluded from our catalogue a reference from our home Kapo Green because they started to add the pbo formula, a synergizer that increases remanence and strengthens the action of the product, highly controversial.

We are therefore very vigilant to use only natural substances in insecticides. However, although we are talking about natural active ingredients, we must be careful about their use. It's not because it's natural, it's safe. Therefore, the use precautions of this type of product must be respected. It is a contact product and has no remanence. after their application, they will only take a few hours. therefore there is no interest in leaving the products in place. think of aerating well during and after treatment. soil and treated parts may also be leached.
The only risk (even if it is a minor) for a child at a low age would be that he remains in the same room at the time the product is applied. it could inhale the product or move to "four legs" on treated surfaces. it is therefore recommended to deviate it a few hours.

We often have people who encounter carpet beetle invasions (especially in the spring). Most people get out of it. but each case of figure is different. This depends on the degree of invasion, the configuration of your accommodation, and especially how you apply the products. This is why we are trying to describe in our file on the carpet beetle the method of action. it is adapted according to each case. But, by experience, better than less. that you didn't all have them in one treatment, that's no wonder. This is why we recommend to renew treatment about 1 week after the first. This allows to destroy the carpet beetle that evolved from an egg stage to an adult stage in 7 days and that you had not touched the first treatment. have every treatment, you weaken them and decrease them.
It is important to carry out each treatment in one time, in order to be sure to touch a maximum of antirene and to avoid it moving.
