Finding small, fluttering moths in your kitchen can feel alarming. You might imagine them spreading everywhere, ruining your food, and taking over your home. But take a breath—pantry moths are a common nuisance, and with a little patience and a few practical steps, they’re very manageable.
Here’s what you need to know, and how to handle it with calm, practical care.
How Do Pantry Moths Get In?
Pantry moths are clever little hitchhikers. They often find their way into your home by:
Coming in with groceries – They can hitch a
Flying in from outside – Open windows and doors can let them in.
Spreading from neighboring homes – In shared buildings, they can travel through vents and cracks.
Hiding in open containers – Any unsealed dry food is at risk.

Sign What to Look For
Sightings Flying moths near your pantry or kitchen cabinets

How to Handle a Pantry Moth Infestation
Step 1: Identify the Source
Go through your pantry and inspect everything. Check for webbing, larvae, or any signs of contamination.
Common sources include: Flour, cereal, grains, pasta, spices, dried fruit, nuts, pet food, birdseed, and any unsealed food.
Step 2: Discard Infected Items
If you find contaminated food, seal it in a plastic bag and throw it away. It’s best not to try to salvage it.
Step 3: Clean Thoroughly
Empty your pantry
completely.
Vacuum all shelves, corners, and cracks.
Wash surfaces with soapy water.
Wipe down shelves with vinegar.
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 helpful way to monitor the infestation and reduce the population.
Step 5: Prevent Future Infestations
Store food in airtight containers (glass jars or 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 as natural repellents.
Can You Save Contaminated Food?
In most cases, it’s best to throw away contaminated food. The larvae and webbing make it unappetizing and potentially unsafe.
However, for severe infestations, freezing food for at least 4 days can kill eggs and larvae. If the contamination is minor (just a few moths), you can remove them and use the food—but if there’s webbing or larvae, it’s best to toss it.
When to Call a Professional
If the infestation is extensive
or keeps coming back despite your efforts, consider calling a pest control professional. They can identify the source and treat hidden areas.
