Larvae feed on grains, cereals, dried fruit, nuts, pet food, bird seed, and many other stored products. They spin silken webbing in food, often creating clumps. Adults don't eat.

Pantry Moths (Indian Meal Moths) in Boise & the Treasure Valley

Pantry moths show up year-round in Boise homes, but we get the most calls in late summer and fall when bulk grocery hauls and stocked-up bird seed sit in warm Treasure Valley garages. Foothill neighborhoods with backyard bird feeders, plus families who buy grains in bulk, are the most common starting points. Almost every infestation we treat traces back to a single bag of grain, flour, or seed brought in from somewhere else.

FAQ

Pantry Moths (Indian Meal Moths) Questions Answered

Common questions about identification, prevention, and treatment

Where do pantry moths come from?

Most infestations start with moths already present in purchased products. Eggs or larvae hitch a ride in grains, flour, cereals, dried fruit, pet food, or bird seed. They rarely enter homes from outside.

How do I get rid of pantry moths completely?

Complete elimination requires: 1) Remove and inspect ALL dry goods, 2) Discard anything infested or questionable, 3) Thoroughly clean pantry, 4) Store remaining food in airtight containers, 5) Use pheromone traps to catch remaining adults.

Are the moths I see flying the problem?

Flying moths are adult males, which is why pheromone traps catch them. They signal an active infestation, but they aren't the source. The larvae in your food are. You have to find and toss the infested package to actually fix it.
