When you'll see Indian meal moths

Indian Meal Moths are most active in spring, summer, fall and winter. In spring, overwintering adults become active and many species lay their first eggs. Summer heat speeds up development, so populations can grow quickly. In fall, many bugs look for shelter, and some move toward or into buildings. In winter, activity continues mainly indoors in heated spaces.

Typical places to check: pantry or stored food and kitchen.

About moths & butterflies

The Indian meal moth is one of the moths & butterflies. Moths and butterflies have wings covered in tiny scales and go through complete metamorphosis. The caterpillar stage does all the feeding and damage, while adults sip nectar or, in some species, don't eat at all.

In pantries and closets, the moths you see flying are a signal. The real problem is the larvae feeding in food or fabric nearby.

What to do about it

  1. Throw out every infested package and check nearby sealed items
  2. Vacuum shelves and cracks, then wipe with soapy water
  3. Use pheromone traps to catch males and monitor progress
