4J Insecticide - Tested by an independent laboratory

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.

To obtain a 1.5% concentration, you will need to dilute 15 ml of insecticide concentrate with 985 ml of tap water.

Au sujet du Pyrèthre

Produit qui m'a tout l'air d'être efficace contre les acariens, certes, mais à voir sur les psoques (?)...

Francis O


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.
