If you are having a problem with moths, The Revenge Pantry Pest Traps will help you get the infestation under control. The pest traps help to control moths by using a special moth sex lure or pheromone that attracts male moths. These moths are found in flour, rice, crackers, dog food, bird seed and cereal. The Revenge Pantry Moth Trap works by luring male moths into the trap with a pheromone lure that female moths use to attract males for mating. Reducing the number of male moths is key to stopping the reproductive cycle. Traps will last for up to 3 months after they have been opened. Each box contains 2 traps.
