TL;DR: Pantry moth larvae eat dry stored foods, especially grains, flour, cereal, rice, pasta, nuts, seeds, dried fruit, birdseed and dry pet food. They are less likely to feed on plain sugar and do not eat salt.
If you open your pantry one morning to a flutter of wings—or notice webbing, larvae or clumps inside dry goods—the source is often closer than it seems.
Adult pantry moths are usually the ones you see flying. The larvae are the ones feeding inside stored food. This guide will help you inspect the right pantry items first, separate high-risk foods from lower-risk ones and avoid wasting time on unlikely sources.
What do pantry moths eat?
Pantry moths eat dry, shelf-stable foods during the larval stage. When people ask what pantry moths eat, they are usually trying to find where the infestation is hiding. The better clue is not the adult moth flying nearby, but the condition of the food itself.
Look for webbing, clumps, shed skins, fine debris or small worm-like larvae inside packages. These signs often point to the source, especially in opened, loosely sealed or long-stored dry goods.
A simple rule: if the food is dry, shelf-stable and made from grain, seed, nut or fruit ingredients, inspect it before moving on to lower-risk items.
Pantry foods to inspect first
Start with the foods pantry moths are most likely to infest. High-risk foods contain the starches, proteins or oils pantry moth larvae need to grow. Medium-risk foods can be affected, especially when stored near an active source. Lower-risk foods should be checked after the high-risk foods.
High-risk foods | Check these first:
- Flour and baking mixes
- Cereal, rice, oats and pasta
- Nuts and seeds
- Birdseed
- Dry pet food
- Dried fruit
Medium-risk foods | Check these next:
- Dried beans and legumes
- Spices and dried herbs
- Chocolate and cocoa
Lower-risk foods | Check these last:
- Tea and coffee
- Sugar
- Salt

Overlooked pantry moth food sources
Once you’ve checked the obvious staples, look for dry goods that tend to sit forgotten in cabinets, garages or storage bins.
Check:
- Wheat-based or grain-based foods, including cornmeal, barley, couscous, crackers, biscuits, cake mixes and grits
- Powdered milk
- Baking chocolate
- Candy or sweets that contain nuts, grains or chocolate
- Soup mixes
- Older drink mixes, coffee alternatives or tea blends stored in paper packaging
- Potpourri mixes
- Decorative wreaths that include nuts, fruit, seeds or seedheads
Do pantry moths eat sugar?
Plain sugar is unlikely to be the source of a pantry moth problem. If moths appear near sugar, check the container lid, rim and nearby shelf area before discarding it.
Do pantry moths eat salt?
No. Salt is not a pantry moth food source.
If you notice moth activity around salt, treat the container as a location clue, not the likely source. If it is sealed and clean, move on.
Do pantry moths eat spices?
Sometimes. Spices and dried herbs are not usually the first source to inspect, but they can be affected, especially when they are stored near an active pantry moth source.
Focus on the container rather than the spice itself. Check lids, rims, labels, bag folds and the shelf around older jars or packets. If everything looks clean, continue down your inspection list.
Do pantry moths like coffee or tea?
Coffee and tea can be checked for pantry moth activity, but they are lower-priority items.
Loose tea, coffee alternatives and paper packaging deserve closer inspection because they are more exposed than airtight tins or newer, well-closed containers.
Where to inspect for pantry moth larvae
Pantry moth larvae usually begin inside or near the food source, but they may move away as they mature. That is why larvae can sometimes appear beyond the original package or pantry shelf.
After checking the foods above, inspect:
- Shelf corners, shelf liners and small pantry crevices
- Cabinet corners and nearby wall or ceiling edges
- Garage storage areas, if pantry foods, birdseed or pet food are kept there
- Nearby rooms or closets where larvae may have settled
What to do if you find pantry moths in food
If a food item is clearly affected, discard it. Then clean the shelf, check the items stored closest to it and move unaffected pantry staples into sealed containers.
After cleaning, use Six Feet Under® as directed on affected shelf areas or crevices to help eliminate any remaining pantry moth eggs and larvae. Let the area dry fully before returning food items.
Dr. Killigan's Pantry Moth Traps help monitor adult moth activity and capture adult males, but they are not a substitute for removing the food source. For the full cleanup process, read our guide to getting rid of pantry moths.
