Booklice (Psocids): Tiny Pale Insects in Books and Cupboards

Booklice are tiny, pale insects that appear in damp cupboards, books and stored food.

The short answer

Booklice feed on mould and starchy residues, and thrive in humid conditions. They are harmless to people but signal damp. Reduce humidity, clean mouldy surfaces, air books and cupboards, discard infested food and use dehumidifiers. Persistent cases need moisture investigation.

Signs

• Tiny, pale, soft-bodied insects.
• Found near books, paper, cupboards and food.
