How do you prevent mealy worms in cornmeal?

To prevent mealy worms in cornmeal, store the cornmeal in airtight containers to prevent pests from accessing it. Keep it in a cool, dry place, as moisture can attract insects. Additionally, you can freeze the cornmeal for a few days before storage to kill any potential eggs or larvae. Regularly inspect the contents for signs of infestation and discard any affected products promptly.
