When deer venture into a yard and find some plants to munch, they are likely to return. In some cases, this area will become the local hangout for the four-footed animals. Some people purchase a deer fence or commercial sprays to deter the creatures. The most industrious gardeners may choose to address the deer problem by making homemade deer repellent.
A commercial product can become an expensive repellent method if many plants need protecting. Homeowners who make their own deer repellent save money because many deer repellent recipes include household items on the ingredient list. Commercial products often contain chemicals, which can be unsafe for use on vegetables. These are not included in homemade recipes.
The need to mix the solution prior to each use is one of the main disadvantages of using a homemade deer repellent. Since the mixture does not feature a substance that helps it stick to the plants, it must be reapplied frequently. Reapplication every two to three weeks and also following a rainstorm is usually recommended.
One recipe for an effective repellent can be sprayed onto plants before buds appear, for best results. Blend five eggs and mix them with one cup of yogurt, milk, or buttermilk and two tablespoons of hot sauce. Add one teaspoon of liquid dish detergent and one tablespoon of vegetable oil. You can also add 15 drops of cinnamon oil or two teaspoons of crushed garlic, if desired.
After blending all of these ingredients with one quart of water, combine them with an additional three quarts of water. Strain the solution prior to transferring it to a sprayer. This will keep the sprayer from clogging and preventing the solution from reaching the plants. Occasionally, ingredients should be changed because alternating bad tastes confuses deer. Use the repellent in a small area first to ensure that it is effective on local deer.
