I went out and dumped a container of coffee grounds I was saving for compost on the bed with the slugs the other night. I saw about 8 of the slimy things and bagged them for the trash. I can't stand to squash them so I tie them in a plastic bag and put them in the trash. I sprayed too but then, of course, it rained. I'm going to keep putting the coffee grounds in there and hope that helps as well. I put the dregs from the coffee pot in a sprayer and have been using that undiluted, after sitting around all day it seems pretty strong.
