Haven't tried it, but a local nursery here in Texas is passing these out.
4 tablespoons ground cayene pepper 1 cup white vinegar 1/2 cup peeled garlic 1 cup clear ammonia 1 cup Murphy's oil soap 1 bar Ivory hand soap (optional)Boil cayenne pepper in vinegar for a minute or two, then strain through a coffee filter. In a blender, puree the garlic in 2 cups water, then strain the mixture through another filter.
Combine the two filtered liquids with the ammonia and oil soap in a 3 gallon garden sprayer. Fill the sprayer to the maximum level with water, and spray mixture around all areas you want to protect. For extra stickiness, float the bar of Ivory soap in the sprayer.
For maximum effectiveness, reapply weekly as well as after rains. If deer browsing is intense, spray more frequently.
