The slug bait that says may harm daylilies has NEVER bothered any here. I believe I use the same product as Fred and he doesn't have any problems with it bothering the daylilies either.
I was thinking of using the sluggo, but I've read it can kill the earthworms; don't know if that has been proven or not or how much it takes to kill the earthworms.
You can spray ammonium or coffee and I've heard it's effective. Some on here have tried it so maybe they will chime in.
