Pheromone traps
It may take some time to completely eliminate a large meal moth infestation. Stay with it. As long as you are trapping adult moths keep searching for the infestation. It is possible that there is more than one infestation.
Moths lay eggs in grains, cereals, dry fruit, nuts, bird seed and dry pet food. Moth larvae feed on the surface of these materials and often cover it with a fine webbing. Infested foodstuffs quickly spoil. Moths can chew through thin plastic bags to get at, or escape from, contents.
