For slugs I use sluggo, it is iron something. Works great.

There are various brands of slugs/snails bait on the shelves of HD , Lowes and elsewhere. They all work KILLING s&s. "Bait" is a wrong terminology. b/c s&s are neither attracted to it nor eat it. It just destroys s&s, as they crawl over the stuff.

Another EFFECTIVE method to combat s&s, is to hunts them after dark, w/flash light. Combo of the above can keep them checked.

I live in PNW, and summers are pretty much the only time of year it doesn't rain. I don't mess around with beer bait or going after them at night. They are major here and will take out your whole garden. I use sluggo and as long as I stay on top of it, it is the only thing that works for me.

I love Sluggo. Easy to sprinkle around, made of organic stuff (iron phosphate in a starch base). Don't get the Sluggo Plus because it has spinosad, an insecticide, which kills things you don't need to kill.
