I use the slug pellets for some years very regularly in my fairly large garden and can only confirm the excellent efficacy. Above all else, has convinced me that this unpleasant critters retreat to their burrows, so no ausgeschleimten carcasses are visible, which also then must be disposed of. The long effectiveness despite heavy rainfall stands out effortlessly from other, similar products. I can only recommend Ferramol! For me, the best remedy "Glitschis" as I always call :-)
