Booklice

Natural Habitat

Damp, warm environments with high humidity; often found in books, pantries, under wallpaper, or near leaky pipes.

Diet & Feeding

They feed on microscopic mold, fungi, algae, and starchy materials like book binding glue and grain-based boxed foods.

Behavior Patterns

They are wingless, soft-bodied insects that prefer dark, undisturbed areas. They do not bite humans or pets but can multiply rapidly if high humidity persists.

Risks & Benefits

They do not transmit disease or bite, but they are a nuisance and can contaminate dry food products. Their presence is often a biological indicator of moisture or mold issues in a building.
