Product information "Asselfrei - Woodlouse trap"
Biological wooden trap for controlling woodlice in the house, cellar and on the balcony.

Effect of Asselfrei

Asselfrei contains nematodes of the species Steinernema carpocapsae embedded in a bait. The woodlice are attracted by the bait and crawl into the trap openings. During their stay at the bait, they ingest the nematodes. The woodlice die after about 7 days. After 14 days, usually 80-100 % of the woodlice have died. The trap is effective for a period of 3 weeks.

Application of Asselfrei

Simply place the trap where the problem with the woodlice exists. Asselfrei can be used all year round.
One trap covers an area of 5m2.

Control woodlice

Nematodes are natural enemies of woodlice. The nematode species Steinernema carpocapsae specialises in woodlice, among other things, and can use them for its own feeding and reproduction. The nematodes are contained in a bait that is placed in a trap. The woodlice are lured into the trap by the bait, where they become infected with the nematodes and die after a few days. The trap can be used indoors all year round.

How do nematodes work?

Nematodes are approx. 0.5 mm long threadworms, of which there are over 20,000 different species worldwide. The species Steinernema carpocapsae is specialised in controlling woodlice and is particularly effective. The nematodes penetrate the woodlouse and secrete a bacterium with which they live in symbiosis. The bacterium kills the pest and the nematodes multiply in it until it is consumed. The nematodes then move on to infest the next pest. This process repeats itself until all the pests have been controlled.
