The Indian meal moth is a very common household pest. The distinctive 1/2-inch long adult is easily recognized by the pale gray and coppery brown front wings. The dirty white to pink larval stage is a caterpillar that crawls away from the infested products to find a place in which to transform to the adult. The caterpillars feed on the surface and produce silk webbing throughout the food source. The life cycle can be as short as 25 days. They can feed in dried fruits, powdered milk, chocolate, flour, meal, dried dog food, bird seed and a variety of food stuffs. They prefer coarse flours and corn meal.
