How do i get rid of earwigs without making a mess?

they're a damp problem more than a bug problem. Pull mulch and leaf litter back from the walls, fix anything dripping, and run a dehumidifier if they're turning up in a basement. A rolled up damp newspaper left out overnight catches loads - shake it into soapy water in the morning. Indoors they don't breed or do any harm, so vacuum them up and sort the damp.
