Locate the source of the infestation. This is typically found in your pantry. Cereals, grains or dry dog foods are the best places to start looking.
Purchase a pheromone based trap. Pheromones are natural compounds that the insects use to communicate. These pheromones will lure the moths to the traps.
Lay your traps near the infested areas. Approximately one of every eight moths that approaches the trap will enter it, according to Ohio State University
