Now if it will keep all critters...

Terracycle's Deer Repellent seems to work based on "Dr. Joe's" demo. Best thing about the product (besides being all natural) - it comes in a reused 1 liter bottle. Looks like a nice little spray nozzle as well.

Have to try this to keep out Bambi. A plus if it keeps out Chuckie and Chippy too.
