- Webbing: silk-like webbing in food packaging, containers, or on pantry shelves.
- Larvae: small, cream-colored larvae with brown heads visible in or around infested food.
- Damaged packaging: tiny holes or chew marks are larvae entry points.
- Odor: infested food may emit a musty or unpleasant smell.

Once an infestation is detected, quick action matters:
- Discard infested items: throw away all contaminated food and inspect nearby items carefully.
- Deep clean: empty the pantry, vacuum shelves, and clean with warm, soapy water or a vinegar solution.
- Seal food properly: store remaining food in airtight containers to prevent re-infestation.
- Use pheromone traps: place moth traps in the pantry to capture adults and monitor the infestation.
- Seek professional help: for severe infestations, consider contacting pest control specialists to ensure all stages are eliminated.
- Inspect groceries: check food packaging for signs of infestation before purchasing, especially bulk items.
- Use airtight containers: transfer pantry items into glass, metal, or plastic containers with tight-fitting lids.
- Practice FIFO: use older food items before newer ones.
- Keep pantries clean: regularly wipe down shelves, vacuum cracks and crevices, and discard expired items.
- Seal entry points: fix cracks and gaps in walls, shelves, or around windows.
