They come in with groceries. Pantry moths can hitchhike on food products from grocery stores.
They fly in from outside. Open windows and doors can let them inside.
They spread from neighboring homes. If you’re in a shared building, they can travel through vents and cracks.
They hide in open containers. Any unsealed dry food is at risk.
Signs You Have a Pantry Moth Infestation
- Sightings: Flying moths near your pantry or kitchen cabinets.
- Webbing: Silky, web-like material in food containers, corners, or cracks.
- Larvae: Small white caterpillars in food or crawling on surfaces.
- Pupae cases: Small, brown cocoons in cupboards.
- Food contamination: Clumpy, webbed, or strange-smelling food.
How to Handle a Pantry Moth Infestation
Step 1: Identify the Source
Start by going through your pantry and inspecting everything. Check for webbing, larvae, or any signs of contamination.
Common sources: Flour, cereal, grains, pasta, spices, dried fruit, nuts, pet food, birdseed, and any unsealed food.
Step 2: Discard Infected Items
If you find any contaminated food, seal it in a plastic bag and throw it away. Don’t try to salvage it.
Step 3: Clean Thoroughly
- Empty your pantry completely.
- Vacuum all shelves, corners, and cracks.
- Wash surfaces with soapy water.
- Use vinegar to wipe down shelves.
- Pay attention to cracks and crevices where larvae might hide.
Step 4: Use Traps
Pheromone traps attract and catch adult male moths. They’re a good way to monitor the infestation and reduce the population.
Step 5: Prevent Future Infestations
- Store food in airtight containers (glass jars, plastic containers with tight seals).
- Freeze grains and flours for a few days after purchase.
- Keep your pantry clean and clutter-free.
- Inspect new groceries before storing them.
- Use bay leaves or cedar in your pantry (natural repellents).
