Garden slugs make their presence known by chewing holes in leaves and creating slimy trails over plants and pavers. They’re the bane of hosta lovers, with their non-stop chewing turning pretty hosta leaves into lace. Control slugs by placing boards or burlap bags throughout the garden overnight. Slugs will crawl beneath before daybreak—and you can scrape them into a bucket of soapy water. Slug baits, a resident toad and a healthy population of ground beetles also help control slugs.
