The Maxforce FC Roach Stations can last up to 1 year if there is still bait left inside. The stations have a translucent plastic top so you can see the bait tray inside. In a bad roach infestation, roaches can eat the bait in as little time as 1 or 2 weeks. You should replace the station once the bait is gone, or if you feel the station has become contaminated. Otherwise, as long as there is still bait inside, it will be good for one year.
