Natural insecticides : a respectful solution to insect control

Unwanted insects in our homes can quickly become a nuisance. But there's no need to use harsh chemicals to get rid of them. Penn'Ty Bio offers a range of natural insecticides, providing environmentally-friendly solutions for controlling flying and crawling insects, without compromising the health of your family or the planet.


Effective, nature-friendly alternatives against unwanted insects

Diatomaceous earth : Diatomaceous earth is a versatile, non-toxic solution for controlling crawling insects. Made from the microscopic shells of fossilised diatoms, this powder acts mechanically by perforating the insects' protective layer, causing them to dehydrate. With no harmful chemicals, diatomaceous earth is ideal for sensitive areas such as the kitchen and garden.

Insecticides based on plant pyrethrum or margosa : Products based on pyrethrum and margosa are plant extracts known for their repellent and insecticidal properties. They work effectively against a wide range of insects, from mosquitoes to ants and flies. These plant extracts offer a natural option for controlling pests without compromising human health or the ecological balance.

Miscellaneous traps : Insect traps are an environmentally-friendly alternative for attracting and capturing unwanted insects without the use of chemicals. Whether it's a trap for flies, wasps or mosquitoes, these solutions make it possible to reduce the insect population without resorting to aggressive methods.


Personalised advice and specialised dossiers

We have a number of dossiers dedicated to the main insects in our homes. In these dossiers, you can find out how insects live and the solutions we offer to combat them.

As well as offering a range of natural insecticides, Penn'Ty Bio provides advice on use and maintenance to optimise the effectiveness of these products. Information on how to target problem areas, precautions to take when applying and methods to maximise results are available to help consumers get the most out of their purchases.

4J Insecticide - Tested by an independent laboratory

Ideal for combating small insects

This ready-to-use 100% plant-based insecticide can be used to treat house dust mites but also all small flying insects (gnats, mosquitoes, etc.)

But be careful, just because an insect is small does not mean it is not resistant. For example, for bedbugs, this 1.5% insecticide is not sufficiently concentrated. A concentration of at least 5% should be used, the 10% concentration being the one we recommend against resistant insects (hornet, bedbug, wood bug). 

Advantages of this insecticide with vegetable pyrethrum

+ Ready to use. No mixing required. Just use it as is!

+ Easily biodegradable

Ready-to-use product

+ Safe under normal conditions of use, for individuals and warm-blooded animals. (Be careful with cats and fish when treating)

+ Composed of potassium, essential oils and vegetable pyrethrum, this insecticide is authorised for use in organic farming for the treatment of buildings.

+ Its smell is pleasant

+ Leaves no trace, after evaporation of the water, it can be used on all surfaces (carry out a test beforehand)

+ In accordance with EEC regulation N°2092/91 annex II paragraph B (pesticide), this insecticide can be used in organic farming against harmful organisms in livestock buildings and installations.

How should it be done ?

To be effective, it is first necessary to find out where the insects are coming from and then to treat them. (There is no point in killing isolated flies if you have a place where they proliferate and reproduce).

Destroying the eggs, larvae, nymphs, etc. will eradicate the colony fairly quickly.

To destroy insects effectively, you need to know a minimum of information about them. Our different thematic files can help you. 

Tips for use / Treatment ideas

- Shake well before use

- Spray on the insects and on all surfaces and nooks where they can settle and reproduce.

- Don't forget the cracks in floors, the gaps in skirting boards, beams, etc.,...

- Treat fabrics or cupboards against moths.

- Treat carpets, bedding against dust mites.

- Treat kitchen cupboards and floors against cockroaches or ants.

- Treat your indoor plants against aphids, red spiders, white flies, Thrips,... (use at 1%)<

- Treat floors against floor fleas.

- Protect or remove food and dishes during treatment.

- Leave to act for at least 30 minutes and air the treated area well.

- A soap residue may remain on the surface after the treatment, a simple wash with clear water using a sponge or a damp mop will remove it.

- To maintain its effectiveness, this product must be stored in a cool, dark place.

Note : This is a contact insecticide, so you must treat the insects or infested areas and not the air with this product. If the insects are not affected by the product, this insecticide will have a repellent and not a destructive action. 

Fabriquez vous même votre insecticide 4JMake your own 4J 1.5% insecticide

For the treatment of large surfaces, it will be more economical to use our 4J insecticide 4J which is the same product but to be diluted with water (15 ml / litre). Mix the insecticide concentrate with water in a sprayer, shake well and apply the solution to the surfaces. To obtain a 1.5% concentration, you will need to dilute 15 ml of insecticide concentrate with 985 ml of tap water.


Active ingredient : Chrysanthemum cinerariaefolium produced from open and mature Tanacetum cinerariifolium flowers with supercritical carbon dioxide - CAS: 89997-63-7 = 0.01875 % (m/m), essential oil complex, vegetable dispersant, QSP water. Allergens naturally contained in essential oils: citral, geraniol, limonene, linalool. 

We answer your questions

▼ How long does it remain active, and does it lose its effectiveness after a while ?
In its ready-to-use form, the delay will be around 6 months. The product will remain usable, but the action of the plant pyrethrum it contains will begin to diminish.
▼ What essential oils are contained in the insecticides and repellent in this range ? Are they highly concentrated (to find out what they smell like) ?
Litsea cubeba, lavandin grosso, lemongrass, geranium etc. This essential oil complex acts as a synergizer in the formula (reinforcing the product's action). The contents of the complex are indicated in each product sheet composition.
▼ It says that Insecticide 4J is "free of Pyrethroids", but you also state that it "contains pyrethrum (neurotoxic to insects)". Isn't pyrethrum a member of the pyrethroid family ?
Pyrethrins should not be confused with PYRETHRINOIDS, which are synthetic products (permethrin, phenothrin, depallethrin, esdepallethrin). To find out more, see our dossier on the subject.
▼ Can 4J nsecticide also be sprayed on the skin (so as not to be bitten by bedbugs). Or is pyrethrum a problem in contact with human skin ?
No, 4J is not designed to be sprayed on the skin, but only on surfaces. There is a risk of allergic reaction. Although pyrethrum is of natural origin, it is not harmless. To protect you from the bites of biting and sucking insects like bedbugs, we recommend our eucalyptus citriodora-based product. This product is specifically formulated for cutaneous application.
▼ Is it a problem if Insecticide 4J is sprayed in a kitchen (presence of food) ? Is pyrethrum toxic ingested by humans ?
Before spraying surfaces with Insecticide 4J, be sure to remove all unprotected foodstuffs (open bag, fruit basket, etc), and this is to avoid ingestion of pyrethrum. Our product has the advantage of containing no additives. Its remanence is therefore fairly short. In just a few hours, the pyrethrum will break down and disappear. On the other hand, if you touch food during treatment, the molecule is bound to penetrate it, and you'll end up ingesting it at some point.
▼ Is it a problem if 4J Insecticide is sprayed on clothing ? Or will it damage them ?
In theory, no. But it all depends on the textile material. Insecticide 4J contains potassium soap, which has an asphyxiating effect on insect larvae and eggs. This soap may leave a small greasy film, but it's still easy to wash off. On valuable or delicate textiles, there are 2 other methods: either use a washing machine at 60°C (for textiles that accept this), or use Ecodoo Tous Insectes aerosol. Place garments to be treated in a garbage bag. Spray inside with Ecodoo insecticide. Close the bag tightly to make it as airtight as possible. Wait at least 24 hours before reopening.
▼ Is plant pyrethrum effective against textile moths ?
Yes, of course. 4J insecticide is a universal insecticide. In other words, it can be used against all insects. The difference then lies in the dilution used. Here are the dilutions we recommend according to target: - 1.5%/2% = Small insects and mites (midges, mosquitoes etc...) - 5% = Most insects, including floor fleas and moths (food and textile) - 10% = Resistant insects ( hornets, wood bugs, horse flies etc..., bed bugs) All the info on textile moth treatment on our folder.
▼ I'm pregnant and have an asthmatic child at home. Is 4J insecticide contraindicated ?
Our 4J insecticide contains plant pyrethrum, potassium soap and a synergy of essential oils. As you are pregnant, it is recommended that the treatment be carried out by someone other than yourself, to avoid exposing yourself to the odors of essential oils contained in the products. The same applies to your asthmatic child. Even if they remain in small proportions, it's still preferable that you don't expose yourself to them. The advantage of our products is that they contain no additives or synergizers in the formulas to increase product persistence. If the treatment is carried out in the morning, you can return to the treated rooms in the afternoon without any worries.
▼ Concerning the conservation of the 4j, will it be sufficient to store it in the s.d.b. without window, illuminated by a lamp only when we pass, or is there a risk that the product will deteriorate ? Is room temperature sufficient, or is it imperative to put the product in the fridge ?
Concerning the storage of 4J, this product is resistant between 10 and 30°C.Above that, the pyrethrum it contains will degrade. Below that, it will crystallize. This will not affect the active ingredient. However, you'll need to leave it at room temperature for several hours (or even a day or two) before the crystals disappear. In absolute terms, this product needs to be protected from UV rays and heat for optimum shelf life.

Anti acarien

J'en applique 3 à 4 fois dans l'année (changement de saison) sur mon matelas pour éliminer les acariens. Très efficace. Bonne odeur. Prix accessible. Livraison rapide et soignée.


Top !

Utilisé contre les pucerons sur un hibiscus d'intérieur qui souffrait... Pas emballé par les produits vendus en jardinerie, et les recettes douces n'ayant pas fonctionné: savon noir... jet d'eau a l'exterieur sur chaque zone touchée pour une action mécanique... les pucerons sont revenus... et il fait maintenant trop froid pour recommencer ! Cela doit faire 3 semaines que j'ai traité la plante et les pucerons ont abandonné on dirait :) et cela n'a pas abimé la plante donc c'est parfait. Methode: j'ai pulverisé dehors, laissé agir 1h a l'air, et rentré la plante.



Très satisfait, on avait un début d'infestation d'acariens de stockage. On a éliminé tout ça en 2j.



excellent produit j'ai sauvé mes plantes



Penty Bio et ses produits , tout super. Pas de reclamation.

Cette dilution à 1,5% m'a permis de venir à bout des acariens dans ma chambre à coucher. En plus du gros coup de ménage, j'en ai vaporiser partout (aussi sur matelas, sommier)

Réponse de Penn'Ty Bio

merci de nous faire partager votre expérience. L'insecticide 4J spécial petits insectes contient du savon de potassium, afin de le rendre plus efficace sur les oeufs et larves. Le traitement peut donc laisser une fine pellicule de savon. Un simple lavage de votre sac, ou seulement des poches latérales, résoudra le problème. Continuez à laisser vos avis car ils serviront certainement à d'autres personnes.
A bientôt.
Penn'Ty Bio


ça colle !!!

De retour de voyage, je spraye toujours l'extérieur de mon sac à dos. Est-ce normal que l'intérieur des poches latérales "collent" maintenant. Avez-vous un produit anti-acariens qui ne colle pas ? Car celui-ci aurait un bon rapport qualité/prix.
