Though it may be enjoyable to live in an area where deer and other wildlife roam freely, there's an unfortunate downside: deer can destroy both landscapes and gardens. To create a deer-proof area, you must find a deer repellant that works. Instead of purchasing a repellant, consider making one yourself from a recipe.
To make a homemade deer repellant, place 3 eggs, 3 tbsp. garlic juice, 3 tbsp. hot pepper sauce and 1/2-cup water in a blender. Process until combined. Add this mixture to 1 gallon of water and fill a spray bottle with the repellant. Spray your outdoor plants to repel deer.
For another deer repellant, place 2 eggs, 1 cup water, 1 cup skim milk and 2 tbsp. liquid dish soap in a blender. Process until combined. Spray on plants.
Another popular recipe is 2 eggs, 2 tbsp. liquid dish detergent and 2 tbsp. oil mixed well. Add this mixture to 2 gallons of water. Fill a spray bottle with this repellant, and spray plants as needed to keep deer at bay.
Combine 1 egg yolk, 1 tbsp. baking powder and 1 gallon of water. Mix well and pour into a spray bottle. Spray plants with this repellant approximately every two weeks to repel deer.
Scatter human or animal hair around plants. It will keep deer away, and as the hair decomposes, it enriches the soil with nitrogen.
