Why do moths appear in food storage rooms and how to get rid of them?

Food moths are one of the most inconspicuous but harmful pests in food storage facilities. They are most often found in areas where grains, flour, cereals, dry feed or long-life products are stored.

Where do food moths come from?

1. Arrives with products from the store or suppliers

The most common source is packages of cereals, flour, rice, or feed that already contain eggs.

2. Improperly sealed packages

A plastic bag or open container is a great place for moths to lay eggs.

3. Damp or warm rooms

Moth larvae multiply rapidly in places where there is warmth and a food source.

4. Old food stocks left in the gaps between warehouses

Small crumbs or uncleaned shelves become an ideal environment for larvae.
