Woodlice breathe through gills—yes, gills, like a fish. They need humidity to survive. If your home is dry, they will desiccate (crisp up) and die within hours. So go on a moisture hunt. Check under sinks, behind the washing machine, around leaky pipes, and in that corner of the basement that always smells like damp towels.
Fix the leaks. Wipe up standing water. Use a dehumidifier if you have to. And no, leaving a bowl of salt on the floor won’t help—please don’t ask why I know that. The goal is to turn your home from a tropical spa into a desert. Woodlice hate deserts.
