How often should I change the Roach Pheromone Traps (M330) that I have put in one of my accounts?
After you place a trap out the pheromone will attract roaches for up to one month, but the glue in the trap will stay sticky for months until it becomes too full of roaches or until it becomes too dusty or dirty to catch roaches anymore.
