Indian Meal Moth (Pantry Moth)
Scientific Name: Plodia interpunctella
Order & Family: Lepidoptera (moths and butterflies), Pyralidae (snout moths)
Size: Adults have a wingspan of 1/2 to 3/4 inch (12-20 mm). Larvae can grow up to 1/2 inch (12 mm) in length.
Natural Habitat
Commonly found in kitchens, pantries, and food storage areas in homes, grocery stores, food processing plants, and warehouses.
Diet & Feeding
Larvae feed on a wide range of dry food products including grains, cereals, flour, pasta, rice, dried fruits, nuts, birdseed, pet food, spices, and chocolate. Adults do not feed.
Behavior Patterns
Pantry moths are typically nocturnal and are attracted to lights. Adult moths are often seen flying near food sources. Larvae are responsible for the damage, spinning silken tunnels and feeding within food products. The entire life cycle from egg to adult can take from one to two months depending on conditions.
Risks & Benefits
Potential risks include contamination and spoilage of stored food products, leading to financial loss and potential health concerns if infested food is consumed (though generally not harmful beyond indigestion). They do not bite or transmit diseases. There are no significant benefits associated with their presence in human environments.
