What is the housefly ?

The housefly, scientifically known as "Musca domestica", is a small insect common in homes throughout the world. Small in size (generally between 6 and 9 millimetres long), its body is covered in short hairs and its colour varies between grey and black. It has large translucent wings, enabling it to move quickly through the air.i worth exploring.

The life cycle of the housefly consists of four stages : egg, larva, pupa and adult. The eggs are laid in decomposing organic matter, such as food waste and excrement. The larvae, commonly known as maggots, emerge from the eggs and actively feed on the surrounding organic matter. Once fully developed, the larvae transform into pupae, where they undergo a transformation to become adult flies. This cycle can vary in length depending on environmental conditions, but can take place in just a few days.

Houseflies are mainly attracted to decomposing food, human and animal waste and organic matter. It also feeds on liquids, using its proboscis to suck up liquid substances, enabling it to absorb sweet liquids such as leftover fruit juice or soda.


How to control houseflies ?

The presence of houseflies in an environment can pose a risk to human health. They can carry bacteria, viruses and other pathogens on their legs and bodies after coming into contact with faecal matter or decomposing waste. By landing on food surfaces, they can contaminate food and cause food-borne illnesses such as diarrhoea, salmonellosis and enteritis.

As well as posing a health risk, they can also cause major disruption to your day-to-day comfort. In the summer months and if you're in the countryside, it can quickly become unbearable. There are several ways of controlling and preventing housefly infestations. These include keeping food preparation areas clean, disposing of waste quickly and using mosquito nets or fine mesh windows to prevent them from entering buildings. At Penn'Ty Bio, you'll find fly traps, repellent diffusers, fly swatters, insecticide-impregnated granules, natural aerosols and more. A whole range of products for natural, toxic chemical-free pest control in your home.


Why use natural insecticides ?

Getting rid of flies is one thing, but wouldn't it be even better if you could also protect your health and the environment? Did you know that some particles of conventional insecticides remain in your treated rooms for several months? Fumigants are the worst because the particles fall back onto all the objects, textiles and surfaces in the room. Unless you wash each item thoroughly, you'll inevitably end up with chemical substances. Opting for natural insecticides will not only get rid of the flies, but also, thanks to the composition of our products and their low persistence, enable you to continue living in a healthy environment.

Trap flies without insecticide

Les avantages du piège à moustiques et mouches

When the sun is shining again, the days are getting longer and you want to air out your home as much as possible, that's when flies invade our homes. They land on you all the time, tickling your arms and legs, inviting themselves onto your plates and feasting on the crumbs you leave behind. As well as being difficult to live with, flies carry bacteria and can contaminate your food. It is therefore essential to limit the invasion and proliferation of these flying pests. 

The Ecofly window fly trap is a real innovation in natural fly control. A product without insecticide, odourless and without any danger for you, your children and your pets. 

The principle

The principle is based on the attraction that this insect has with shiny and reflective surfaces. The reflection of the sun on the shiny silver surface of the trap will strongly attract them. As soon as they want to land on it, they will be trapped by the adhesive part. A simple idea but one that works extremely well. As soon as the weather turns stormy, the temperature rises and the sun shines through your windows, it's time to set a trap.

Trap with 0% biocide

Piège Ecofly - Efficacité prouvée en laboratoire

This trap is a real innovation in the fight against flies in everyday life. Totally odourless and insecticide-free, this product can be handled without danger. The bait is natural, consisting only of a shiny reflective surface. The yellow colour of the trap was also not chosen at random. This colour attracts flies. The neutral glue applied to all surfaces sticks to the insect before it even notices! The attraction and trapping of flies has been proven in the laboratory to be 90% within 5 hours (and 100% within 6 hours). And the big advantage compared to a classic fly trap is that there is no view of the glued flies since the sticky part is located on the outside of your room (unlike a fly tape for example :)).

anti mouches

Bon produit. Action piège infaillible. Livré très vite. Merci


Pas mal mais...

Les mouches mettent des semaines à mourir ; c'est assez glauque.
C'est plutôt efficace, mais je n'en rachèterai pas tant qu'il n'existera pas de recharges. C'est quand même naze de devoir acheter tout l'ensemble. Et pas écolo.


Pas à la campagne

Hélas pas efficace du tout dans notre campagne entourés de vaches ! Peut-être en ville...


marche plutôt bien

il faut vraiment que la fenêtre reçoive le soleil, dommage qu'il n'y ait que 2 recharges, il devrait exister des lots de recharges collantes plutôt que de tout changer



Très bon produit !
