spelling is overrated
I find it makes my slugs and snails a bit twitchy, so I just chuck 'em in the compost bin now.I used to put them under bushes in front garden as there used to be loads of slugs and snails there. It may have deterred them as there are less now, but that might be because I clear the leaf litter too.
Now I put them in the garden waste bin, or food compost caddy.
