Biology
Pantry moths are notorious for their diverse diet, from grains to cereals, and nuts to seeds, Indian meal moths aren’t picky eaters. Their life begins when they lay their eggs in or near these food products, the very same ones you might find in your pantry. As the Indian meal moth life cycle progresses, these larvae hatch and begin to feed on the food around them. And boy, do they eat (for now at least)! They tunnel through food products, causing damage and leaving behind frass (insect droppings) and layers upon layers of silicon thread. This thread eventually becomes sheets which act as a protective layer of insulation from predators. Adult meal moths actually do not eat, it is only during the larval stages that the moths consume any sort of food. Once fully grown, females can lay as many as 200 – 400 eggs in roughly 2 weeks time.
Habitat
Indian meal moths are found all over the world, but they’re particularly fond of warm, humid climates, which are perfect for their development. But don’t think that they only stick to your pantry; these moths can comfortably set up shop in businesses, homes, and even outdoors.
