They can not fly and are not dangerous to humans. The parasitic wasp Trichogramma evanescens is one of the legwheps. This genus specializes in the eradication of parasites. They eat eggs or lavas and make them harmless. Wasps destroy the eggs of clothing moths and food moths.

In about two weeks, the first wasps hatch, which in turn start laying eggs. Depending on the provider, there will be a new delivery of wasp wasp six times every two weeks.
