What you need to know about the silver fish

Silver fish (or lepers) are very agile insects. they owe their name to the small silver scales that cover all their bodies. polyphages, they can eat starch, crumbs, sugar, paper. but they can also stay up to 1 year without eating! They can only live in humid and warm environments, which is why they are found mainly in bathrooms, kitchens, toilets or laundry facilities. with low fertility, longevity (up to 5 years) and a preference for night activity, silver fish usually go unnoticed in the houses. Pay attention to books, especially if they are wet.

1 - Treat surfaces with our insecticide 4j diluted to 5% (see 500ml / 5 m2). Depending on your figure and the surface of the parts to be processed, you can opt for the same insecticide, but underIts concentrated form. You will then need to dilute it with water in a 5% sprayer (or 50ml pure insecticide for 950 ml of water).

3 - You can also treat infested areas to the anti-ant oil, also usable on the silver fish.
