Vebi place the adhesive traps where cockroach activity is observed — in dark, humid and warm places such as under furniture, sinks, appliances, shelves, or affixed to walls. To use: assemble the trap, remove the protective film, and set it in the desired location. The first captured insects increase the trap's effectiveness; activity is maintained for approximately one month. When a trap is full of captured insects, dispose of it. Supermarket
