Fight against fly

(action method, natural insecticides, ...)


Who's the fly ?

la mouche domestique - Musca domesticaOrder: Diptères
Family: Muscled, fannied, calliphoridae
Size: 4 to 10 mm
Location: all habitats
Period: all year


Among all flies that can enter houses, 4 species are found mainly:
- the domestic fly (musca domestica,),
- the fly of stables (stomoxys calcitrans,),
- the small domestic fly (fannia canicularis,),
- the greniers fly (pollenia rudis).

The adult fly feeds on plant debris and animals, sweats, excrements, blood (street of stables). The larva feeds on manure, detritus and garbage.


The fly is very invasive

la mouche des étables - Stomoxys calcitrans The fly colonized all the regions of the world where man lives.
Present from March to mid-November in our dwellings in different forms (larves, nymphs) it does not stay locked all day: in the evening, it will go to the garden, compost, manure, to the duck pond.
She squatters the life pieces she appreciates the freshness and the swelling in the summer, and the attic to winter.
Although not pleasant, most species of flies are useful in our ecosystem (food for birds and fish, compost processing in humus).


How does the fly to walk to the ceiling without falling ?

Vue en microscope de l’extrémité d'une patte de moucheYou noticed it, the fly is an out-of-pocket acrobat! She's the most gifted insect to circulate in every plane, head down. But... it's not magical! Sorry to disappoint you! It actually possesses what can be assimilated to suction cups at the level of its legs.

In fact, it is equipped at the end of each paw of 2 curved claws, 2 adhesive lateral strips and a 3rd pelot called empodium. This is the whole system that allows flies to stick literally to the ceiling or on smooth vertical surfaces. of course,

other insects know how to do it (boths, beetles, bees, ants...), but flies remain the best equipped to achieve this kind of prowess !

On the other hand, flies have a high surface/volume ratio. In other words, they occupy a small volume for a large body surface. due to their low mass, they are more subject to surface forces - such as adhering to the support on which they are located - than to the force of gravity.


What attracts fly ?

1 - the smells: In the house or apartment, flies are attracted to odors. that it smells good: perfume, fresh foods (crues or cooks,) sugar, fruits, vegetables, vinegars... or bad: organic decomposition material, excrements, sewer odors, waste, etc.

And the warmer ... the more the odors are amplified. You better understand why summer there is an abundance of flies in houses and other places. Some flies are baited by us, humans, because we are made up of sodium and other minerals ( tears, sweat) that are salted.

2 - decomposition foods: vinegar flies are most attracted to fruit and vegetables too wall or rotten. put it is not earlier (unfortunately,) especially during the heat days. They are particularly fond of the tea or coffee capsules used, the bouquets of fanned or decomposition flowers, the organic materials found in the trash, the beverage funds (bottle or glass of beer, wine, vinegar, cider). they are totally seduced by all these acid and/or sweet foods.

3 - the farm and the stables: These spaces are composed of odors that flies particularly affectionately (especially autumn flies). cattle, horses, ponies, donkeys ... are very appreciated by these little beasts. They feed on the liquids they secrete around the eyes, the mouth and the museau. Even more, manure, fertilizers, fresh excrements, organic or vegetable materials capture flies that feel a potential for reproduction in these places, especially if heat is present.


The fly is carrying germs

la petite mouche domestique - Fannia canicularis This insect is one of the main bearers of germs. her body frogs millions of bacteria and she often deposits it on food.
Accumulated reserves during the larval stage are sufficient to maintain the adult alive. It still needs a sugar intake, represented in various forms: nectar, pollen, honeylate, milk, sweet liquid, meat, fruit, ... without being a great traveler, the fly can travel several kilometers in order to feed itself.
Liquid substances partially digested, are then sucked. As she feeds, she reges part of her previous meal (the famous flies bites!) and it is above all in this way that she transmits pathogenic microbes to our foods.

So be careful not to use ultraviolet traps or electric grid. as soon as the fly comes into contact with these devices, it explodes and debris full of pathogenic microorganisms spread within a 3 metre radius contaminating everything.


The fly reproduces very quickly !

La mouche des greniers - Pollenia amentariaReproduction takes place in the summer, where the conditions are most favourable. a beautiful summer suits him, but too much heat is fatal: beyond 30°C, it becomes sterile.

Its favorite breeding areas are hot and humid places such as immondices, human excrements left undiscovered, cracks, rubbish, manure, crottin, muds, meats, cheeses, trash.

Depending on heat and humidity, the eggs hatch at the end of 8 to 24 hours and then become larvae (also known as tickets) and then nymphs for a short period of time, before turning into flies.

The adult lives 10 to 12 days. There are 10 to 30 generations a year.

A single female can lay up to 1000 eggs, in several decks of 150 eggs each. in the best conditions, it can mate 2 weeks after hatching and lay 4 days after mating.


Attention to the choice of insecticides !

Special fly aerosols based on pyrethrinoid reinforced with ddvp are to be banned because flies, due to the rapidity of their breeding cycle, will easily develop resistance to aerosols.
Attention also to bio-based insecticides that contain permethrine (organochlorinated pesticide of the pyrethrinoid family). This product is certainly biodegradable, but it has nothing natural (synthesis) and even less organic. the toxicity of permethrin in man is not yet classified, but it is very toxic to all cold-blooded animals and is not tolerated in the cat (it can cause symptoms of convulsions type).

Attention also to insecticides where it is written in bold, "natural active ingredient. manufacturers know how to draw your attention and sell products that are not as natural as they claim. Most contain other components such as pbo (pyperonyl butoxide) or permethrin ! 

At penn'ty bio, we offer natural insecticides without additives or petrochemicals.


Our tips to reduce the amount of fly

1 - Keep the detritus remotely and maintain an irreproachable level of cleanliness

Before any curative action, a number of preventive action may be applied to limit the presence of flies. In your house :
- deep cleaning behind your furniture or appliances.
- clean the bottom of your bottles of sodas, vinegars, alcohols... before storing them.
- keep the doors and windows closed at night, otherwise installa mosquito net.
- protect your fruits and vegetables with bulk bags or protective covers.
- have a trash with a hermetically sealed lid and wash it twice a month with vinegar water.
- clean behind your animals (clean the bird feeders, you can even remove the food for the night).

And in farm-type buildings, stables or chicken, if not already done, a minimum of elementary rules will have to be applied which will limit their reproductions and their diets:
- Get away from the building all piles of manure, piles of garbage, sewer water, garbage bag. all decomposition organic matter.
- breaking down ventilation systems to dry buildings.
- the water and the auges must always be clean.
- do not leave milk deposits near the milking room or breastfeeding place
- the litter must be as dry as possible (e.g. washers at the right height, renewal, ventilation).
- lisier pit: stir regularly to destroy developing larvae.

2 - Touching reproductive areas

You must try to stop their development by dealing with our insecticide 4J diluted to 5% all areas where they can reproduce (see 500ml / 5m2 treated surface) .

3 - EliminationBy mass

You have to try to destroy a maximum of flies. The more flies, the more they will lay and the more you will have. the means at your disposal are numerous but not always effective! the fly remains a difficult insect to eliminate at 100. %.

3a. . Mechanical means
They remain the simplest of use and have no harmful character for us and our environment: the indemodible flies tape. its long sleeve and flexibility make it a formidable weapon! ♪ ribbons catch flies of course catch-small for window edgeOr the vacuum cleaner.

Concerning the vacuum cleaner, avoid leaving flies in the bag, otherwise you may find yourself with a larvae colony! You can spray through the suction tube an insecticide, but be careful not to use a flammable insecticide, otherwise you may risk your aspirator getting on fire.

3b. . Chemicals
Most products purchased in trades are not always effective and not always very healthy for health. carefully read the label of your product and especially the precautions of use. Don't forget to take a look at the mandatory pictograms !
To treat ambient air, use theaerosol EcodooOr flying insecticide Aries, 2 products consisting of'plant alcohol, essential oils and vegetable pyrethra, specifically developed to fight flying insects. This type of product will be very effective but on time as the flies will return from the opening of a window or door! plant pyrethra without additive to benefits but its lifespan is limited in time (may be remanent), so it will have to be put on a regular basis. insecticides freezing effect or All pests will also be dreadable in direct jet. immediate effect!

Finally, always in the field of fumigationfogger habitat BiovétolWill give excellent results on this type of insect. insecticide based on plant-based assets (pyrethre + géraniol) for the background treatment of habitat. very volatile, the solution is deposited in the smallest corners where pests and insects are located. immediate action. 3 different formats exist: 75ml for treatment less than 15m2, 150ml, for treatment less than 30 m2. Finally, 250ml, for treatment greater than 30m2.


4 - to keep them remotely

When the amount of flies in the room is reduced enough, you can protect your space from intrusion of new flies. all places by which they may enter (ridals, sailings, door frames, etc.). but also all surfaces you want to protect. the goal is to create a repulsion volume.

But, sorry to tell you, there is no miracle repulsiveness! a repulsive protects at best a few dozen centimetres around the surface treated. the more treated surfaces you will have, the better you will be protected but you will not disappear all flies.

4a. our repulsive insects Pyrethre/Géraniol showed a highly significant intrinsic repulsive effect (94)% vis-à-vis flies (and 98% on mosquitoes) in direct application on the inert surface as well as a repulsive effect remanent two weeks. for 500 ml to treat 5m2.
4b.our second repulsive insect habitat containing eucalyptus citriodora will also yield very good results and will offer an ideal barrier against fly.
4c. THEanti-mouches Aries offers another solution to protect surfaces over a short period of time. there is, either in spray, or concentrated solution (for example, it can be used pure or diluted to protect soil or garden furniture).
4d. in the field of repulsion, our anti-moustic spirals and flying insects will allow you to keep the flies away. The smoke that consumes these spirals is composed of pyrethre. the flies will be immediately disturbed and will pass their way, see will die for those who insist. up to 5h30 per spiral.


And if you have a horse, a pony, a donkey or even a cow, our insect repellent ALT'O ZINSECT (spray or gel)Will be perfectly suited to protect it from flies that grow during the summer period. a 100% vegetable formulation combining 3 recognized and very effective active ingredients to keep these ugly flies away that spoil their daily lives.

- the traditional house trap: glass trap or plastic bottle to hang or to lay, add water and honey or a little sweet syrup, flies will be drawn to sugar and drown. If you use a plastic bottle, remember to recover the top of the bottle, return it to create a funnel on the bottom of the bottle.

Showing questions about fly

Q: I am interested in your products and especially insect repellent, however to help me in my choice, can you answer the following questions: - I live in the countryside in the middle of fields, livestock and next to a pond: so flies + mosquitoes + spiders + cousins.: Is it better to use the "ready-to-use" repulsive or make a more concentrated dilution? - my house has 10 windows + 1 bay + 3 exterior doors + 1 terrace : what volume do I need to spray ?

R: Do not hope to remove all insects from the house and especially spiders with a repulsive product. the more a product is concentrated the greater its radius of action. It depends on what you want to treat to limit the penetration of flying insects. life depends mainly on its exposure to the sun (degradation) and heat (evaporation). Let's say every week to start, increase or decrease the frequency according to the result. a 0.5l vaporizer allows to treat 5 m2 of surface, but only treat non-absorbent surfaces otherwise the product enters the support and loses its efficiency; preferably treat sails rather than amounts especially for openings to 80 cm.

Q: We've been in flies. We have cows not far from our home (see black flies ceiling in September mainly) but throughout the year, do you think that with these 3 products the vapo all insects + repulsive spray + anti flies we would get to the end ?

R: It is very difficult to completely eliminate flies unless the origin of proliferation is removed. However, well employed repellants can help you to have much less. Insecticide is only useful to kill them by spraying them. You also have granules and ribbons against flies.

Q : My dog doesn’t risk poisoning if it swallows insects (mainly flies) that would be dead with your product.

R: No danger, the product for itself is not dangerous in normal use and even less the consumption of treated insects.

Q: We have a septic pit and as soon as the beautiful weather appears we have flies that come out of it and we have indeed in the house; Do you have a solution ?

R: I also have a pit but I have no fly, the pit being perfectly waterproof I think the solution is there but if it is not possible it is always possible to use anti-Mouche repellants, granulated or ribbons to fight them.

Q : Hello can tell me if I have to use the more repulsive insect flies concentrate for more effective action against flies of the stables. we are in the countryside next to a farm with cows and sheep. Thank you

R: The anti-Mouches aries (concentrated or spray) is a good repulsive. I also know our repellents Penntybio are effective on flies (e.g., pyrethre and eucalyptus citriodora). a you use them according to the surfaces to be treated. You also have granules and ribbons against flies.

Q : I own a pavilion in the country. My attic is built, my problem has been that for several years in the unappointed part, I find hundreds of flies on the ground. My blanket is in flat tiles and I don't have under roof, flies can pass. I don't have a dead bird either. You can tell me why I have so many flies in this place and tell me what solution I could adopt to remove them. a treatment would he try despite my attic being of course aerated ?

R: That you find dead flies in an attic, that's normal. Many times, they come in but not out. On the other hand, there's a lot of them, it's not normal. I have no explanation, it happens frequently in unmanned holiday homes. our insect repellents are effective on flies. they allow a protection of 2 to 3 weeks. Besides treating your tiles on the inside, I don't see too many other solutions. We never tried this technique !

Q: My attic is invaded by the flies and it even makes noise at night so many. Can you tell me what the right product is? Thanks in advance and bravo for your site and your products.

R: It is not easy to treat in an attic, given that space is often very ventilated. we can try to treat the inner roof with our insect repellent, it should limit the entry of new flies. you can also destroy the flies already present with our 4j insecticide.

Q : For 3 years my dog has been assaulted by flies since April and this for 7 months. They suck his ears especially so well that he bleeds them and that every day. I've already tried a variety of products, notably emoline for horses, I'd like to find a much more effective product and I don't need to apply every day.

R: We only have one product that could be suitable: the insect repellent alt'o zinsect spray or gel. you will find on our site.

Q : in summer I have many flies and mosquitoes flying in my apartment, could you advise me on essential oils or a repulsive. On the other hand I have a cat and I heard that essential oils were toxic to them. What about it? Thank you

R: You have a mixture ready on our site in the synergies of essential oils: peaceful nights. for the cat, essential oils can be dangerous but only in application on the skin (see our thematic folder on this topic).

Q: We live in a house with a large glass bay (2.40) and many openings (windows) and since the beginning of summer, we have been invaded by flies. that we must do to try to reduce this nuisance, knowing that we have 3 children 8 years, 6 years and 2 years. Therefore, we do not want to use toxic and dangerous products. give us the approach to follow and the products to buy. please

R: You don't have much solution, whether in natural or chemical. The only solution I see would be to put sailing in front of the glass bay. you can deal with repellent; for small openings, treat only the frame. To kill them, you also have granules and ribbons against flies.

Q: We have flies in the patio when we have lunch or dinner. Do you have a repulsive to broadcast in order to move them effectively ?

R: Unfortunately there are not many solutions against the fly. I personally kill them by spraying on the 4j insecticide diluted to 5.% if you have a lot of it, I advise you a garden sprayer and you water them all. After a few days, they should disappear. You can also, in a corner, place our anti-mouche granules.

Q: 10 days ago, a smell of decomposition flesh was felt in my cellar. Of course I immediately tried to find the decaying animal in my garden. Unfortunately it seems to me that this one went to die under my stone staircase, place inaccessible. Currently, asticots (flies) have invaded the land bordering this staircase. What can I do to eliminate them? I know the best way to do it is to find the body; But in my case it's almost impossible !

R: In this case, it is actually quite complicated. remains the solution of fumigation treatment using our fogger habitat Biovétol. trying to place it as close as possible so that the smokes penetrate under your stairs. As for the corpse, if you don't have access to it, you'll have to wait until it breaks down on your own.

Q : My mother lives in an old house and the toilets are of origin, septic tank. It is invaded by flies and we can't destroy them. Your product can be put in the pit, safe for my mother and will be quiet then, more invasion. Please let me know your answer because I don't know what to do.

R: I don't see how to use our products that are biodegradable in a pit filled with bacteria! you can treat the flies present but you cannot prevent them from coming back. I also have a septic tank but I have no fly. My pit is perfectly waterproof and no fly can enter or exit. See what you can do on the side of your pit.

Q : I'm looking for a flies repulsive that we're regularly infested in the summer by leaving open windows and doors, something non-toxic to man, we have children in the early age.

R: We have various repulsives on our site, based exclusively on natural products that give good results in repulsive. Another solution, to kill them, you have our 4j insecticide or granules and ribbons against flies.

Q: I am a farmer and I have lodges on the farm and I am invaded with flies in my buildings I would like documentation about it. more if you have a stand at the agricultural fair in libramont (belgium) let me know thank you for your answer.

R: We have various repulsives on our site based exclusively on natural products that give good results in repulsive. Another solution, to kill them, you have our 4j insecticide or granules and ribbons against flies. due to lack of time, we do not participate in any demonstration.

Q : We have a small rabbit farm and are this year invaded by flies. can we use your insecticide in the building where the slaps are located: is this safe for rabbits? Which concentration to choose knowing that the building is equipped with openings (which do not ferment and on which we have laid mosquito nets) ?

R: You can use our safe insecticide in your livestock. it is allowed in organic farming. for flies, they must not descend below 5% (standard concentration all insects). you can treat with insecticide all surfaces where flies are in order to eliminate a maximum.

Q: I'm an avitor. I've got problems with flies that reproduce in the cracks. How can I get rid of it? the surface has treated is 2000 m/2 and this 2x per year. what product? What success? What quantity per treatment? What price? delivery in belgium possible ?merci

R: The three strengths of our insecticide are: non-toxic, insect destruction and egg destruction. As the flies are small insects, I think a 2% concentration has to be enough to try. to be effective, 1l of insecticide/ 10m2 is recommended. you can first take a small bottle of insecticide to do a few tests and if the result suits you. Then you can consider treating all of your surfaces. we deliver in belgium without worry (see shipping costs grid).

Q: I don't know what product to choose. We are going to live in the countryside near the stables and we have flies in profusion, more of all small wasps stinging. The main part is 70m2, and is duplex. We have a parrot, 2 cats and dog. what can you advise us in this context, which is more than efficient and especially non-toxic to us and our animals? There's too much choice, and I'm a little lost. Do you have anything so effective that is not sprayed ?

R: To protect yourself from flies and safe to use and not in spray you have: sticky ribbon and anti-mouche granules.

Q: I own a mountain chalet (1600 m,) and am invaded by flies and stains especially on the facades in meleze and then inside. What do you have as an effective and sustainable treatment to offer me ?

R: For outdoor treatment, we can offer you our repellent to spray on the facades but we must know that no natural product (or non-natural) is very long resistant to the sun. It is usable inside. otherwise, it is possible to use the traditional flies catch ribbon, not very aesthetic but effective, and the granules, well placed it is effective.

Q: We have thousands of flies on our facade walls (we are close to a cow field) that you recommend? Do you have sales points in Department 69?

R: You have the solution to kill them, at least those on the facade, with our insecticide 4j diluted to 5.% equip you with a sprayer type garden and water the flies. those affected by the product will die. It will not prevent other flies from coming. You can start over until flies or product are exhausted! we can also treat the wall with our insect repellent but if it lasts 3 weeks in the sun, it will last much less.

Q: I want to spread essential oils in my home, in addition to the insecticide and the repulsive you propose, to hunt many flies. Indeed I have a large glass bay and I think the repulsive will not suffice, and moreover I am a little afraid to dry my tissue so I will complete by diffusing. What mix do you recommend? I thought I'd take geranium, lemon, thyme, lavender, clove. Knowing that I have a 1 year old girl, is what it can be dangerous, what are the essential oils to avoid? I think I also take your "child night" mix for her since it is done on purpose; however, you specify on your page not to use essential oils before 3 years is why I wonder for my "anti flies" diffusion!

R: If for mosquitoes we know the effective essential oils to remove them (since the aim is to mask the body smell of humans) for flies, it is a little more complicated. I have no idea of the essential oils to use, but I advise you to spread thyme thymol or even clover in the presence of young children. On our website you will find information on the diffusion of essential oils.

Q: I have received your email, about the insecticides, but I would like you to tell me what effective product against flies, which have invested my attic for at least 4, 5 years, despite a roof reshuffle where they found nothing, as well as having put several years in a row the product "Kapo crawling flies" we couldn't manage to stop this invasion. Thank you for giving us the miracle solution.

R: We regularly have requests like yours: an attic invaded by flies. If there are flies, it is that they find what to reproduce (e.g. animals, corpses, manure). the question is, do they reproduce outside or in? Is your attic closed and isolated, do you have velvets ?

Q: We have a closed and isolated attic, all black. When we look at a lamp, we don't see flies flying or dead. on the other hand they manage to descend into the rooms below, certainly attracted by the light, but impossible to see them coming out of a precise place, except to see them dead in front of the windows, that is, clarity. Is kapo crawling fumigene flying crawling, is quite powerful, because it's already been at least 3 years since we put it twice a year. Do you have another product to offer or experiment. The rooms are not occupied.

R: In general, flies are attracted to heated and bright places. We rarely find flies in a dark place. Why do you think the flies go through the attic since you can't find them (not alive or dead) and that this place is dark? it is possible that they arrive directly in the rooms without passing through the attic. the Kapo is effective, it will kill insects present in the room but that's all; he's not gonna kill the insects that are behind a partition or the ones that will come after. unfortunately there is no miracle product to fight the fly except to attack the source of proliferation but when it is behind a partition, it is impossible or then to mouth all access with silicone. We got home Kapo very effective special flies granules.

Q: My combles are invaded by frogs of the granaries (pollenia rudis). What product in your range would you advise me to get them away? I do not necessarily seek to kill them, but to dislodge them because they come out at the first ray of sun and decorate by thousands the white facades of our house. Is the smoke pyramid effective for these flies? What is its duration of action in repulsive mode? When do you need to use it ?

R: Attic flies take the habit of haraaming by sheltering in all the corners and cracks of the house. on the other hand, their small sizes, the combles and barns of the houses are easy to access for them. They can be grouped by hundreds of clusters waiting for temperatures to rise. When spring arrives, they then seek to go out. They don't always find the way out. This is also why we can find them around the doors and windows of our houses. the attic flies do not do any damage but can be particularly awkward from their large number.

The fly of adult granaries feeding on the nectar of flowers, so it is brought out of your home to feed.

You can choose not to eliminate them but know that this insect can reproduce extremely quickly, up to 4 generations per year if the temperatures are high. I advise you to proceed as follows.

It is important to identify the nest and access points. you can proceed in 2 times:

First of all, treatment using our 4j insecticide. it exists in its already diluted form and ready to use at 5% (recommended concentration against the fly) either in its concentrated form, which will allow you to make larger treatment surfaces (up to 200 m2). for the concentrated product, you make the dilution 5% with water in a garden sprayer. application directly by spraying on visible flies and in accessible interstices. This insecticide is a contact insecticide. so that it works properly, it is necessary to get in touch with insects (eggs, larvae or adults).

In a second time, you can set up a repulsive to prevent flies that they reinstall in the place. for this we have 2 products that will work, with 2 different assets. one is the repulsive to the pyrethre and géraniol. it exists as for the 4j, either ready to use, or in concentrated form. or our repulsive insect habitat composed of eucalyptus citriodora. like 4j, to be sprayed on surfaces.

Finally, you can if you want to use the smoke pyramid or our fogger habitat. It should eliminate much of it. its duration of action remains limited (a few hours) since it is an insecticide. It can be used at any time of the year. the number of flies is the most effective. do not forget to condemn the points of access identified (as far as possible obviously). This will limit their resettlement.
