ANGOUMOIS GRAIN MOTH INFORMATION & FACTS

The Angoumois grain moth (Sitrotroga cerealella) is 1/2 inch long and pale yellowish-brown in colour. These moths may be seen fluttering in the house, often around dusk. As with weevils, the larval stage develops in whole kernels or caked grain. Interestingly, popcorn and decorative ear corn are common sources these moth's commonly infest. Barley, rye, corn, oats, rice and various other seeds can be infested.

The life cycle (egg to adult) of the Angoumois grain moth takes about 6 weeks. The adult resembles a clothes moth but can be recognized by the finger-like projection of the hind wing tip.

The Angoumois grain moth is most active during winter months, when temperatures are lower.  Any stored products that have been infested should be thrown out.
