Where They Come From

• Existing home pests (moths, silverfish) chewing into packages.

Prevention

• Transfer flour, grains, pasta, cereal to airtight glass or plastic containers immediately after purchase.
• Paper bags are easily penetrated.
• If pests persist, you have a broader infestation—call a pest control company.
