I used a nasty mixture of cayenne pepper powder, hot sauce, garlic powder and onion powder�heavy amounts of all of it, and then used about 1/2 gal of water heated everything together on the stove�not boiling though. After letting it cool and sit for a few days to ferment, put it in a spray bottle and mist the plants. You can save the reserves for later usage. You will have to repeat after a heavy rain though. I only had to spray 3 times early this year and since then they go out of their way to walk around the garden. After that overly sensitive nose gets a whiff of that stuff and their tongue feels that burn they have a tendency to not repeating the same behavior.
