Small reddish-brown beetles about 3-4mm long that feed on flour and cereal debris in warm buildings. May be accidentally introduced into the larder in packaging or in the ingredients themselves.
Commonest species are the Rust Red Flour Beetle and the Confused Flour Beetle (which in turn is often confused with the Rust Red Flour Beetle).
May produce five generations in a year and adults can live for over a year. The eggs stick to flour particles and the yellow-brown larvae, about 6mm long, crawl about very actively.
A minute, slow-moving, white or pale-brown creature only a barely visible 0.5mm long, with eight legs. A pest of cereals and cereal products especially if they are damp.
Moths whose grubs feed on stored food – especially cereals, chocolate, cocoa,dried fruit, nuts and any sort of flour product.
Adults are mottled grey and brown. 10-15mm long. Larvae are dirty white with brown heads and grow up to 12-15mm long, spinning a light, matted webbing as they feed.
Both grubs and adults, therefore, can be pests in the kitchen, to which they may be introduced from shop or mill.
A family of very small (about 3mm) flies, some with prominent red eyes, characterised by a slow hovering flight in which the abdomen hangs down. All are associated with rotting fruit and vegetables or fermenting liquids. One species breeds in sour milk, for example, in the residue of forgotten milk bottles.
A general term for various very small (3mm) beetles that feed on moulds in ill-ventilated, damp buildings.
