Infested Pantry Items: What to Throw Away and What to Save

When bugs appear, deciding what to keep is the hard part.

The short answer

Throw away open or paper packs with live insects, webbing or clumping. Sealed, unaffected items may be saved after checking and cleaning. Freeze mildly affected small quantities. When unsure, discard. Clean the pantry before restocking.

Discard

• Items with webbing or live larvae.
• Open packs near the source.
• Clumped, musty flour.

May keep

• Sealed cans and jars.
• Sealed packs after inspection.
• Mildly affected small items after freezing.

Then

1. Empty the pantry.
2. Vacuum and wipe.
3. Let it dry.
4. Restock into airtight containers.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
