Many food co-ops across the country use our trichogramma wasps indoors to control Indian meal moths with great success. These small, parasitic wasps do not bother humans and have a wingspan of 1/50th of an inch. In most cases, you will not notice them as they search out and destroy moth eggs. For what it’s worth, Indian meal moth has become a big problem now that many grocery stores are open 24 hours per day. It used to be that these stores sprayed for meal moth when they were closed — liability issue now prevent this.
Trichogramma wasps are an effective, natural control that can be used to control Indian meal moths without toxic sprays. Here’s a link that should help:
