It takes some time to work effectively, but all crawling insects are susceptible to Diatomaceous Earth when spread around the home and yard. They sell it at most garden and hardware stores (especially the neighborhood stores instead of big box) it comes in different brands. It is completely safe, completely chemical free, and fine for family and pets, and it will also take great care of slugs if you have any issues with them as well in your garden. Basically it looks like a dust, but it is the fossilized skeletons of diatoms (single celled organisms) and it is basically microscopic glass. It won't cut us or our pets but it will cut into the exoskeleton of crawling insects and dehydrate them. The only problem I've had with it is that it does wash away in the rain, so only use it outside if you're expecting a few clear days, just sprinkle it down wherever you're having troubles, they crawl through it, and your problem should soon be solved! (to use indoors just leave it around the house for a little while and then just vaccuum it away) Hope this helps! I know how much I HATE seeing earwigs around my home and yard (I know they're harmless but they're still one of the creepier of the creepy crawlies! ick) and this has worked for me!
