I had this friend . . . Collect slugs. Smoosh up in a blender. Thin the sludge with water and a little unscented ammonia. Sprinkle around. Her claim was that the remaining slugs are repelled by the shredded remains. She also swore she bought the extra blender at a yard sale. For that matter, I've heard that if you eat a nice venison dinner, wait a few hours and then go urinate around the garden the rest of the deer think a deer-eating predator is in the neighborhood. Do Not confuse these two techniques! Judy in New Jersey
