Few things derail your cooking plans faster than opening a box of pasta or flour and discovering insects inside. Homeowners throughout St. Louis deal with pantry pests more often than they’d like, and once these insects find a reliable food source, they’re quick to settle in.
Pantry pests—including pantry moths, weevils, pantry beetles, and several other food-loving insects—are notorious for sneaking into dry goods and multiplying quietly. They can enter your home through groceries, damaged packaging, or tiny cracks, and by the time you notice them, they’ve usually spread to other items.
That’s why knowing how to prevent pantry pests is essential. The professionals at Bug Out help homeowners across St. Louis practice effective pantry pest prevention, and we’re sharing the strategies that make the biggest impact.

Tips for Preventing Pantry Pests
Keeping pantry pests away is much easier—and far less stressful—than removing them after they’ve spread. A few consistent habits can significantly reduce your chances of bringing an infestation home. For stronger pantry pest prevention, follow these recommendations:
- Inspect food packages carefully; avoid anything with punctures, broken seals, or visible damage.
- Don’t leave open food out where pests can access it.
- Use airtight containers for flours, cereals, grains, snacks, and pet food.
- Close pantry doors when not in use.
- Check window and door screens for holes or gaps.
- Seal cracks or openings around your home that may serve as entry points.
- Label containers with the date they were sealed to help track what needs to be used first.
- Throw away expired, stale, or unused dry goods.
- Buy smaller amounts of foods you don’t use often so they don’t sit long enough for pests to find them.
- Keep compost containers sealed tightly indoors.
- After any pantry pest issue, inspect all remaining food items thoroughly.
Removing Pantry Moths and Larvae
While adult pantry moths are the most noticeable, it’s their larvae that cause the contamination. Larvae feed on a variety of dry goods—including grains, baking mixes, nuts, dried fruit, and pet food—making them especially destructive once they’re established.
To remove pantry moths and larvae effectively:
- Take everything out of your pantry and check each item carefully. Bag and discard any infested products and take the trash outside right away.
- Clean all shelving, corners, cracks, and trim pieces—larvae often hide in small, overlooked spaces.
- Once surfaces are completely dry, set pheromone traps to catch adult moths still lingering.
- Store replacement food in strong airtight containers to prevent new infestations.
If moths or larvae keep returning after these steps, a more extensive treatment is likely needed.
