Why do woodlice's go under pot's?

Woodlice, or pillbugs, seek shelter under pots and other objects to escape harsh environmental conditions, such as heat and dryness. These creatures are sensitive to desiccation and prefer damp, humid environments to survive. The underside of pots provides a dark, moist refuge where they can hide from predators and maintain their moisture levels. Additionally, this behavior helps them find food sources, as decaying organic matter is often found in such locations.
