Non-toxic glue trap for detecting and locating the presence of giant silver fish and catching them indoors. It is recommended to place several traps in different places at the same time. So use all the traps in the package at the same time. If you need more traps, you can buy a refill pack containing only glue traps. The dispenser contains enough bait for about 100 glue traps. The bait attracts the giant silver fish to the trap and they get stuck on the non-toxic glue surface of the trap. After detecting and locating the giant silver fish, biocide treatment is started if necessary.
