General Facts

Why do I have pseudoscorpions?

Pseudoscorpions, also called false scorpions or book scorpions, live in damp debris, soil, and trees, and are commonly seen under tree bark, in leaf and pine litter, in tree hollows, under stones and in caves. They prey on insects such as carpet beetle larvae, booklice, ants, mites, and small flies, using venom to capture and paralyze their prey. They then pour a mildly corrosive fluid over their prey and ingest the liquefied remains. Depending on the size and species of the pseudoscorpion, they sometimes hitch a ride on insects, where they feast on the parasites present on the host. When they do end up in homes, they're usually found among dusty books full of mites, or in damp areas like basements, bathrooms, laundry rooms, or around drains. During cold weather or while mating or molting, pseudoscorpions also make disk-shaped cocoons by spinning silk from a gland in their jaws.
