Indian Meal Moth

General Description
The Indian meal moth (also spelled “Indianmeal” moth) is a slender moth that folds its wings over its abdomen when at rest. It is approximately five-eighths of an inch long with the outer half to one-third of the front wing covered with reddish-copper scales, though they are often rubbed away. The moth typically feeds on grain products, dried fruits, seeds, nuts, powdered milk, chocolate, candies, dog food, and bird seed. The larvae are caterpillars about one-half of an inch long, ranging from a dirty white color to brown, sometimes with a pinkish or greenish tinge. They produce silken threads that are visible on the food source.

General Control
Indian meal moth caterpillars feed on various food items, and the sources of infestations can be difficult to detect. Sanitation and proper storage of food products are important parts of prevention and control. Foods should be inspected for infestation before being stored in the facility. Temperatures below 0 F for six days will kill Indian meal moths.
