I have lot of slugs in my backyard. I have tried Copper wire, beer, and picking them up with my hands. But not sure from where they get back. I don't want to use any harsh chemicals to kill them, but I don't like them either. I want them gone. Please help.
You can make a normal table salt circle around your garden or put salt where they commonly. Salt kills them, even though it is cruel it is the only solution I know of. Hope this helps.
