Biology:
Eggs are laid over or near the products. Larvae are mobile over products or bags, where they feed and produced silk which may form large webs. When completely grown, they leave the products and move towards the structures or package openings.

Pupae may be immediately formed, becoming adult moths. However, most of them only become adults within a year, keeping the infestation. Adults are short lived and do not feed. They are active at night and usually fly towards the structure’s roofing. They live for 13 to 14 days and a female may lay 279 eggs.

Life cycle takes 50 - 90 days under optimum temperature conditions. The picture below shows the moth again and the larvae.
