Next time I’ll look for Sluggo, generally we’ve been choosing between “Cory’s Slug & Snail Killer” and “Cory’s Slug & Snail Death”. FWIW, ‘Death’ leaves dead slug bodies littered around the place while ‘Killer’ lets them live long enough to crawl off and expire elsewhere. At least, one hopes they expired, there’s no dead slugs laying about to prove it worked but there’s less slugs afterwards. I’m sure “CS&S Death” is totally toxic to just about everything. I’ll look for Sluggo next time.
Hmm, ‘bait’, yeah, one would expect it to draw in more slugs. Kinda like planting something tasty around what you want to keep so they will eat the sacrificial plants instead of the protected one. Still, that seems to be feeding them and not getting rid of them. Does the bait also kill them or just draw them off elsewhere?
I’ve noticed slugs seem to like marigolds but they don’t seem to eat them. I’ve had raised bed gardens with a row of small marigolds planted around the edges and in the mornings I’d see loads of slug and snail trails all over the marigolds but not in the rest of the garden. The marigolds didn’t seem eaten, either.
Another option is either copper tape or diatomaceous earth sprinkled in a line around the garden. They can’t cross either one.
