Pheromone traps for the adult moths and residual insecticidal sprays are the two most common recommendations. Our top recommendation is the Propest Pheronet Trap
The Propest Pheronet Trap is a distinctive trap in that it not only is designed to capture the pantry moths, like the Indian Meal Moth, but also Cigarette Beetles. Simply peel the paper off to expose the glue. The pheromone is impregnated in the glue, it has no external pheromone.
