The Indian meal moth damages:

The Indian meal moth, scientifically known as Plodia interpunctella, primarily causes damage during the larval stage of its life cycle. The larvae are the ones that feed on various stored food products, particularly grains, nuts, dried fruits, and other pantry items. They create webbing and can contaminate food with their frass (feces) and silk webbing, making the food unsalable and unsafe to consume.

While adult Indian meal moths are often seen flying around kitchens and pantries, they do not feed on food; instead, their role is primarily to reproduce and ensure the continuation of their life cycle. Therefore, even though they are a nuisance, the actual damage to food products occurs when the larvae are active. Options that suggest damage in the adult stage, in all stages, or that the moth only damages wool fabrics are not representative of the Indian meal moth's behavior and feeding habits.
