Jim...I've tried the egg mixture before...but not with baking powder. Will try that next IF my latest concoction doesn't work.
I put about a dozen hot D'arbol chili peppers in a blender along with ground black pepper, 'bout half a cup of Tabasco sauce and water. We're fixing to spray my plants and flower bed in a few minutes.
We also extended the existing electric wire a few feet to protect the part of the patio where the doe has entered....leaving muddy hoof prints behind!
great recipe jim, sent it to my sister. she has 30 deer a night on her front lawn and eating all her summer plants and bushes. she buys some concoction from the store, but says it is very expensive for the amount you get. will be trying your recipe. thanks for posting that tidbit
