Beds mites - House dust mite
The mites settle in your beds, in your armchairs? difficulty: you don't see them! Find in this file a set of answers and products that will allow you to fight this insect, which is omnipresent in our homes.
Acarien des beds (dermatophagoides pteronyssinus)
Acarien des maisons (glycyphagus domesticus)

Period : all year round
What you need to know about the mite
The beds mite is the most common in the houses. The beds mite rather feeds tiny skin waste and mold filaments. the mite of the houses, on the other hand, feeds mainly on sweet organic matter. It can therefore be found in the dust of houses but also in all sweet foods or dried fruit.
They are omnipresent in our environment, but the smallness of it makes it most often unnoticed: 1 g of dust can contain up to 1,500 mites! These are tiny animals (0.3 mm) of the family of arachnides such as spiders and not insects.
To live, mites need a wet environment ✱(50)% and hot (about19°). They can live on both natural and synthetic fibres such as mattresses, animal skins, sofas or carpets.
With a temperature of 25° c and a hygrometry owed to 75% the mites proliferate very quickly, hence the interest of regularly aerating the living parts.
Attention to mites: risk of allergies
Mites do not transmit contagious diseases but may cause allergic reactions such as chronic cold, bronchial asthma and atopic eczema. the main allergen is found in their suspended dejections into the ambient air and it is in contact with the skin and respiratory mucous membrane that the allergy declares itself.
- The allergy threshold is about 100 mites/g dust
- 20% people are sensitized.
- 60% asthmatics are sensitized.
- 25% asthmatics have symptoms caused by these arachnides.
Our trials with insecticide 4j to 1.5%
Given the small size of the houses mites (less than 0.5 mm) we were unable to verify the effectiveness of our insecticide 4j to 1.5%, but we tested it on another type of mite: the red spider that is frequently found on plants in warm and dry weather. after a little blow of spray, "red agarian" passed from the living state to the dead state (see photo).
We also tested our insecticide 4j on de real spiders much larger but with a concentration of 5.% each time the mortality rate is 100. %.
1 - Eliminate house dust by regularly passing the vacuum cleaner (preferable to broom) .
2 - Wash radiators, windows and cabinets regularly.
3 - Wash every week at 60°C covers and sheets and monthly covers.
4 - Aerate the rooms day to reduce the relative humidity of the air and the temperature. It is necessary to avoid having a temperature at 20° c and a hygrometry at 50,% which is more healthy for health.
5 - If you can, prefer:
- smooth leather sofas,
- parquet floors, cork plates, novilon or pvc,
- carpets made of shaved-haired synthetic fibres,
- synthetic or cotton blankets,
- the mattresses wrapped in a waterproof cover to the mites.
6 - Pay attention to anything that can generate molds such as pot plants or humidifiers.
7 - Regularly deal with our insecticide anti-mite.
Anti-mite cover. Is that really helpful ?
This is what Dr. Masson thinks, "field allergologist" (source of the article).
"It is much more effective to hunt mites also in the pillow, the sommier, the duvet.
Even if a mattress cover reduces the amount of allergen, it remains sufficient in the rest of the bedding to maintain allergy and asthma.
Then I will continue to advise my patients to put covers on the mattress, pillow, summer and duvet, because the decrease in the amount of mites in the bedding will help improve them.
In fact, only specific desensitization, by increasing the resistance of the body to allergy, will actually solve their problem."
Attention : when you buy an acaricide, check its composition (see our file) Pyrethrinoid family)
Can essential oils be used against mites ?
Some essential oils can be very effective in fighting mites. more accurately, a mixture of essential oils will need to be used to increase the power of their effects (called synergy). these essential oils have excellent insect repellent properties.
One can cite theessential oil tea tree. the monoterpenic alcohols it contains (alpha terpineol and terpinèn-4-ol) will act by penetrating in cells, altering cell membranes and intracellular constituents of insects. They will thus prevent development and cause the death of insects.
THEessential oil clove contains eugenol (action close to monoterpenic alcohols), a substance known for anti-insect action.
Finallyessential oil lavender will complete the formula thanks to the linalol it contains.
Mix in a small spray 100 ml of modified alcohol and 15 ml of each essential oil cited above. Then spray the surfaces where mites are present: mattresses, pillows, cushions, carpets. Make sure there is no one in the room and wait for at least 1 hour. Finally, once we get back, don't forget to take a vacuum to eliminate dead mites that are still allergic. This will probably be repeated regularly depending on the results achieved. If it does not work sufficiently, it will be necessary to move to more powerful natural insecticides (see below).
How to eliminate mites in a sustainable way ?
A - use of our insecticide 4j to 1.5% because :
- It is a natural pyrethra based product that will eliminate adults.
- Depositing a film (potassium soap) on the waste produced by them (e.g. excrements, dust, etc.). prevents them from spreading in the air. predict 500ml / 5 m2 of treated surface.
- Remove the sheets to put the mattresses naked.
- Apply the product to eliminate live mites.
- Air the room and let the product dry.
- Make a good cleaning to the vacuum cleaner preferably equipped with an anti-mite filter (the vacuum cleaner is important, you should not leave the excrements or dead mites on the mattress).
- The pyrethra with low remanence (maximum 2 weeks) treat regularly and at least for each drap change.
- Also treat cupboards and wardrobes and possibly carpets.
Do you have a big surface to treat ?
For the treatment of a complete house or large surfaces such as carpets, carpets, beds ... we recommend that you equip yourself with a sprayer type garden and insecticide 4j in its concentrated form. 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.
B - 2 products, in the form of aerosol, will also be effective for the treatment of mites:
- the anti-mite spray Ecodoo, formulated, inter alia, based on pyrethre
- The anti-mite spray Aries, formulated it based on neem oil, with a less rapid action (as compared to the pyrethre), but a hold in longer time.
C - for assured tranquility, after treatment and passage of the vacuum cleaner, we advise you to use them deodorizing granules anti-acariens. it will allow you to reject a delicately scented air (menthe - eucalyptus) and sanitized, but also to destroy the mites and other parasites present in the bag of your aspirator, thus reducing the risk of allergy in man and animal.
D - to radically eliminate surviving mites, use thefogger habitat Biovétol, automatic diffuser composed only of plant-based assets (exist in 3 formats).
E - to finish it bicarbonate soda is an ideal ally against the mites for the following reasons:
- Laboratory studies have shown that bicarbonate, whether powdered or sprayed with water, has a dreadful effectiveness against mites. For example, 20 g of bicarbonate powder (the more fine the bicarbonate and the more effective it is) per square meter of surface to destroy all mites in less than 2 hours.
- It is not toxic to us! a grain of bicarbonate that comes into contact with one of our mucous membranes (eye, mouth, lungs...) that are wet immediately dissolves without irritation. On the other hand, the chitine which constitutes the shell of the mite does not allow the bicarbonate to dissolve, and it will be damaged as soon as the contact is established. and as the mite is a stroller, it will not be able to avoid widespread bicarbonate long !
- Bicarbonate is fungalist, it blocks the development of molds. as molds are favourable to the development of mites, and in addition they produce allergens themselves by the production of spores, bicarbonate will be double-effective. it acts both on the mite and on its biotope.
How to use soda bicarbonate against mites ?
Carpets, carpets and mattresses: distribute the powder bicarbonate as evenly as possible (about 20g per square metre or 4 teaspoons). For a single bed of a person, it will take about 35 g and for a bed of 2 people approximately 55 g. brush slightly to distribute and penetrate into the fibres. After about 2 hours (the best being 4 to 8 hours), aspirate and put the sheets and the alley on the mattress.
By spraying or washing: Bicarbonate is also very effective against mites when diluted in water. add bicarbonate in warm water until the grains no longer dissolve, then spray on the support to treat mites. white traces can appear after drying. They will easily disappear when washed. spraying allows a well homogeneous distribution. if the surface is completely humected, there will be very fine bicarbonate crystals everywhere after drying. In the case of machine wash, adding bicarbonate to rinsing water will delay the reappearance of mites.
In the vacuum cleaner: Aspiring bicarbonate (on carpet, mat or mattress) will neutralize the mite activity in the vacuum cleaner. Unfortunately, allergens already present in the bag will not be removed, and it is better to have a vacuum cleaner equipped with a hepa filter to avoid dispersing them in the room. But at least, with bicarbonate, the mites will no longer produce new allergens in the bag! do not hesitate to use in addition our deodorizing granules anti-acariens for aspirator.

Frequently asked questions about mites, august and red spiders
Q: Would it be nice to know if an anti-atile product exists for mattresses if yes you advise me ?
R: We have a small insecticide with mites (the 4j diluted to 1.5%) that you can use to treat your mattresses, but this product with little remanence will need to be passed regularly. we also have other products, in aerosol this time, to treat mites: the bomb Ecodoo Mites or the bomb Aries Acarien.
Q: Is it possible to treat a specific area with your product. What concentration do you recommend me to do it? Will it be done by watering or spraying the supposed area ?
R: Yes, but to be really effective, it would be better for this area to be perfectly twisted before (at least for grass)? I think 2 to 3 per cent will be enough. watering would be more efficient, but a garden sprayer should do the job.
Q: So I would like to know if your "anti-mite" can be used without any danger inside the house, in the beds and all objects in direct contact with my children? What product do you recommend ?
R: On our site you will find several safe products, to be used in the treatment of mites.
Q: I'm looking for a trap for small red spiders, also called Augustas, based on pheromones. Does that exist ?
R: Although the red spider and the Augustat are part of the mites and live both in the grass, there is no connection between the two. the red spider (family tretranychidae) is a parasite of plants, while the larva of the Augustat (drumidion mites) is a blood sugar. apart from that, I don't know a trap, either for one or the other !
Q: I just bought a mattress for my future baby. This mattress has undergone anti-mite treatment based on a permithrine. your page about this molecule includes possible neurological impairments.
R: Like all pyrethrinoids, it is active in the nervous system by disrupting the conduction of the nervous influx along axones. Normally, permethrin is not toxic to man, but very toxic to all cold-blooded animals and is not tolerated in the cat where it causes convulsions type symptoms. the adverse effects they would present may lead to the death of the animal. (the Cnitv-Lyon has recorded 345 cases of poisoning - some dogs and cats by pyrethroids over a three-year period).
Q: I've got parasites in my little kitchen like a bunch of pelicles, but it's squeezing, it's moving, and even after I washed it in bleach it comes back in the hour. Tell me what to do thank you.
R: A priori, given your description, it looks like mites, but to be certain it would take a little more information: what do they look like, steal, are they worms ?
Q: Which organic insecticide use to treat mites (red spiders) on a lemon tree? (ex: insecticide 4j to 1)%
R: Our products, for regulatory reasons, can only be used on apartment plants but in this case you can use 4j to 1% or insecticide ready to use at 1.5%
Q: I just discovered tiny white beasts, we'd believe in dust, but looking carefully at it moves. Could you tell me what I have to do, please ?
R: Small whites that look like dust, a priori, it looks like mites but to be certain, it would take a little more information: what do they look like, steal, is that what are worms ?
Q: Would you have something efficacious to fight against the Augustas or at least avoid getting stinged.
R: Products based on pmd (anti-moustic) would be effective on sugar insects. our bodily lotion Penntybio contains this substance.
Q: Hello, my daughter is allergic to mites. a part of careful cleaning, do you think essential oils could help it, in what form: swallowing, diffusion or others? her symptoms: sneezing especially in the morning, full nose, fly a lot throughout the year.
R: Apart from using essential oils in diffusion to disinfect ambient air (lemon, lavender,). they will not be able to improve or prevent allergy.
Q: Do they also work on large spiders? I tried a natural pyrethra based product on a big spider, she just turned around and when I offered her the broom, she climbed on it and ran all around. She didn't look sounded.
R: Natural pyrethra is a very light insecticide, all depends on its concentration. So it's not surprising that it's not done. our anti-mite will not be effective on large spiders, it is not intended for this.
Q: I'd like to know if there are "anti-mite" rugs?
R: I know mattresses with anti mites but not carpets.
Q: I have a problem in my kitchen. These are animals of about 1 mm white/beige with legs and they move very quickly. I threw it away, all bleached and everything re-cleaned to alcohol to burn. Nothing to do, I didn't find what could be the nest or so I didn't see it when I threw it away. I feel like they like water, they come back all the time. the formica of the kitchen work plan is de-laminated by making the wood appear and every time the kitchen is cleaned there is the water that stagnates on this wood half moulded (I am rented). Could it be there, the nest of these beasts? Before buying an insecticide I would like to know what these beasts are to better fight them with the right product. Thank you for your help
R: I think I told you on the phone, they're probably mites. the products presented in our file on this insect can help you in their lute. Do not hesitate to get closer to us if you have any questions.
Q: We do a tpe on the mites and would like to know what are the effective essential oils against mites ?
R: On mites, I don't know but you have essential oils like lavender, lemongrass, geranium, which have an action but mainly repulsive.
Q: What are you advising to combat the proliferation of Augusta? for the garden of course, but eventually to protect pets, here dogs? Could the earth of diatomy be effective ?
R: Every year, the heat is the same. the Augustats are out and it is very difficult to escape. for outdoors, you can treat with our insecticide 4j "small insects" concentrated at 1.5%. They are mainly found in shaded and humid areas, near water but you will only kill larvae that are not buried in the soil. at the protection level, I am not sure that the products intended for chips and ticks are effective, the soil of diatomy is effective on all insects but its use in a garden is complicated. As soon as she humidifies her properties are no longer active.
Q: Which product advises me to treat an indoor plant infected by red spiders. Knowing that the ideal being to spray on the plant, isn't that harmful to it?
R: Insecticide 4 to 1.5% (small insects and mites) is not harmful. However, the product contains soap, so if you can, a few days after treatment, shower your plant.
Q: i have an invasion of red spiders, or at least tiny (less than 1 mm) small beasts that look like red spiders. They seem to me black with red antennas and leave a dark green train when they are crushed. the walls of my house are invaded (under the windows' edges, in the window frames, in the windows' foliage, and on the whole wall height in the crepi interstices. I would like to know if the earth of diatomy would be effective to end it??? I spent my day spraying a white vinegar mixture + black soap + bicarbonate that seemed to radiate them at once. in vain: new invasion after 10 minutes. You write that the earth of diatoma is inefficient on the mites, and if it is red spiders, then they are mites. Do you think your product can end this invasion? if yes how can I do it to put it on all my crepi??? by where do I start? there are from everywhere!!! I can't even open my windows because I find them in the house! What frequency is it? Thank you in advance for your answer that I look forward to.
R: Red spiders, Augustats. given the size and period, they are probably small insects of the mites' family. our insecticide 4j diluted to 1.5% is enough to end it. It's a contact insecticide. That is, it will only be effective from the moment you touch them with. This product exists either in its diluted form, ready for use, or in its concentrated form, and it is you that mix with water up to 1.5%. Like all insects, the ideal is to identify and treat households. But in practice, it remains complicated. In your case, I advise you to spray the product on the facade of your wall, insisting on the interstices of the crepi. You can also apply it on the edges and frames of your windows. The more you touch surfaces, the more you will increase your chances of destroying a maximum. make the treatment at the least hot hours of the day (matin or evening) because the pyrethra contained in the formula remains sensitive to the action of the uv and heat. When in the diatomy land, if it is only not effective in external use (due to the fact that it becomes inactive as soon as it is humidified), it can be a good way to fight this type of insect in the indoor environment. diatoma can also be projected on vertical walls. so that it is properly fixed, you will need to mix it with water in a sprayer (between 300 and 500g per litre of warm water). Once projected on the walls, the water will evaporate and the diatomy particles will remain fixed. but once again, be careful, a big averse may lose all the work!!
