Damned little buggers are eating everything but my onions, tomatoes and corn. I have pulled the mulch and large pieces of organic material away from my plants, set out traps (yogurt in containers), sprinkled sage brush leaves around the plants and sprayed w/ a cayenne pepper & chewing tobacco tea. They just keep chomping. :x Any ideas how to control these things without chemicals or the use of animals (chickens, ducks & geese not allowed where I live). Thanks.
