Bait for Earwigs.
Equal parts of soy sauce, cooking oil and (molasses or corn syrup). The molasses or syrup is bait to attract them--the oil doesn't allow them to crawl back out and the salt in the soy sauce finishes them off and makes the mixture dark so they think it is just a hole. Put it in a small container�I use those scoops from laundry soap and place a stone on top but you can use any small container even the bottom of a soda or water bottle and anything for a lid. Cover � inch of the bottom of your container with the mixture and bury it up to the brim in the soil where you have a problem with them. Prop a lid over it so it doesn't get diluted by rain and so it is a nice dark place for them to hide for the night--ha. When you prop the lid, leave a small space for them to crawl into the container. You might have to wait a couple of days for it to work, but I used a baby food bottle and it was full to the brim with them the next day. I was surprised by just how many I did get. Try it, it works
