Flour Moths whose grubs feed on stored food – especially cereals, chocolate, cocoa, dried fruit, nuts and any flour product. Adults are mottled grey and brown and measure 10-15mm long. Larvae are a dirty white colour with brown heads and grow up to 12-15mm long, spinning light, matted webbing as they feed.
Both grubs and adults can be pests in the kitchen, to which they may be introduced from shop or mill.
