Pantry Moths in the Kitchen: Identification, Trapping, and Elimination

Identify the Moth

Small gray moths (3/8 in.) near food storage in Sacramento area are likely:

• Indian meal moth (Plodia interpunctella): Two-toned wings (gray base, copper tips); larvae in grains, nuts, dried fruit.
• Mediterranean flour moth (Ephestia kuehniella): Gray with dark zigzag lines; larvae in flour, meal.
• Clothes moths: Unlikely in kitchen unless natural fibers present.

Pheromone Traps: Targeted Monitoring

• Species-specific traps attract males (e.g., Indian meal moth trap).
• Place near suspected sources; replace every 8 weeks.
• Brands: Insects Limited, J.F. Oakes (high quality).

Source Elimination: The Critical Step

1. Inspect all dry goods: flour, rice, pasta, cereal, pet food, birdseed, spices, nuts.
2. Discard infested items in sealed bags outdoors.
3. Freeze suspect items 4 days at 0°F to kill eggs/larvae.
4. Vacuum shelves, cracks; wipe with vinegar water.
5. Store kept goods in airtight containers (glass, heavy plastic).

When to Call a Pro

If infestation persists after thorough cleanup, hire a local (not national) pest control company. They can treat wall voids, apply insect growth regulators, and locate hidden sources.
