Native58, yes they do work.
I watered them onto my whole garden on Sunday and now no sign of any slugs. Once infected the slugs go underground to die so you will never see them unlike when using pellets or beer traps!
To be certain the nematodes work, I always catch a few and put them in a container then water on some nematodes. Sure enough those are all now ex-slugs.
