Mmmmmm…
I’ve tried those blue pellets (scary), the wildlife friendly version (ineffective), cocoa shells (ditto) and crushed egg shells (utterly useless), but only now have hit on the surefire way to rid my garden of snails: namely cheap red wine and a bowl. Finding snails on my broad beans, apples, alliums and butternut squash used to be horrible; now it’s all I can do to stop whooping in celebration as I pluck them off and casually toss them to an alcoholic demise. I like to think they die happy in their little cocktail party of doom.
You’ve marinated them, now you must cook them. Mine know this and that is why they climb so high ( see May 7th).
