I have been surfing the web on this subject, and have found these methods...if anyone has experience with them, please let me know if they work or are a waste of time:
Baking soda mixed with corn meal, flour or cocoa powder
Plaster of Paris mixed with same things as above
Juicy Fruit gum
Bucket of water with a plank up to the top, so they try to get a drink, fall in and drown (problematic in Minn. as the water will freeze)
