This deer repellent works well.
2-3 Tbls. Cooking Oil 1 Eggs
1 cup Milk or Buttermilk
1 Tbls. liquid soap
1 Teaspoon hot chili oil (optional)
1 Qt. Water
Combine in a blender; egg, milk, cooking oil and liquid soap with one quart of water. Add one teaspoon of hot chili oil if you have it available. Then blend. Pout in a small spray bottle or let sit a day or two, then spray on sucseptible plants every week.
The bad thing is that you have to reapply every week. I am going to try one of the recipes above that have soap or somthing that makes it stay on plants longer.
