this what i did . 1st smash all the snail eggs they look like goo on glass plants and decorations. 2nd take as many as you see and kill them or what ever you want to do with them. Also what ryanoh said do the lettuce , cucumber, zucchini or what ever you have trick , you put a piece of vegggi under a small plate leave it over night and com back the next day and most of the snails are on the plate and take them out.
