Have many tried. Especially the sprays, which are located around 5 EUR usually not very effective. The vermin torments partly minutes until it finally kicked the bucket. Bought at that time because of the silver fish my Vormieterin. All (traps, inexpensive spray, home remedies) has brought nothing. Once the corners sprayed with this stuff, complete rest, nothing but me lives more in my apartment !!! After two weeks, repeated again and final not seen a silver fish. When times a spider is sprayed is after half a minute in Nirvana. Only the big bugs that need ever come out of the forest over a minute there that are very large. Can you recommend !!!
