crusty...dealing with deer from hell

The deer in my yard eat everything, planted 50 evergreens, consumed in 3 days. my recipe seems to be working well. 1 egg...2 tbs roasted garlic hot sauce, 1/2 cup milk, 5 drops dish soap, water. makes 2 qts. use the hottest hot sauce you can find. i have blooming flowers for the first time in 30 years that haven't been fenced in or caged.
