Hi, I was wondering if someone can tell me how to get rid of thousands of snails in our yard? They are eating and disfiguring every plant I have, trees, shrubs and of course flowers (sometimes they even feast on each other). I have used bates (poisonous and expensive for my half an acre yard), beer (not very effective and expensive) I have even squished them to no avail. If you know of any other solution please let me know.
