Silverfish spray against silverfish
I have tried many things, but only with moderate success. Then I read about a spray that should help. So I went to the hardware store / Department of pests and bought a spray. It is called "silverfish spray", costs around 10 euros and is micro-encapsulated. The spray is odorless and colorless, can be easily sprayed into all cracks and works in contrast to the conventional tips and tricks.
You have to be patient and repeat the procedure a lot, depending on the infestation, but in the end I finally have the beasts off.
