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.
Destroy infested food, or return it to the shop with a complaint. Clean out the store cupboard and spray or dust surfaces with a product labelled for stored product moth control.
