Wildlife 5

Deer are beautiful creatures to watch but can be a significant nuisance when they start munching on your beautiful flower garden. If you have been in this predicament and are wondering what to spray on flowers to repel deer, this comprehensive guide is for you.


To repel deer from your flowers, you can use commercial deer repellent sprays like Deer Out, Bobbex, Liquid Fence, Plantskydd, or I Must Garden Deer Repellent. Alternatively, you can make homemade sprays using ingredients like eggs, cooking oil, dish soap, milk, vinegar, essential oils, garlic, and cayenne pepper. These sprays work by making your garden smell or taste unpleasant to deer. Apply them early in the morning or late in the evening and reapply after heavy rain or at least once a week during peak deer seasons.

Commercial Deer Repellent Sprays

Commercial deer repellent sprays are typically the first line of defense when it comes to protecting your garden from these creatures. Some popular commercial deer repellent sprays include:

  1. Deer Out 32oz Concentrate Deer Repellent – Known for its effectiveness and long-lasting protection, this deer repellent costs around $38.95 on Amazon.
  2. Bobbex Deer Repellent – This environmentally friendly repellent uses multiple smell and taste deterrents. It’s safe for humans, pets, birds, and aquatic life.
  3. Liquid Fence Deer and Rabbit Repellent – This spray protects not just against deer but also against rabbits, providing a broader range of protection for your flowers.
  4. Plantskydd – A systemic spray repellent that offers long-lasting protection against deer.
  5. I Must Garden Deer Repellent – This repellent is available in both mint and spice scents. It’s safe for people, pets, and the environment.

Remember, deer can become accustomed to repellents over time, so it’s a good idea to rotate their use and try different products to maintain their effectiveness.

Homemade Deer Repellent Sprays

If you prefer a more natural approach, there are also homemade solutions you can try. Here are some DIY deer repellent recipes:

  1. Egg-based spray: Mix a beaten egg with 1 tablespoon of cooking oil, 1 tablespoon of dish soap, and 1/2 cup of milk in a gallon jug. Fill the jug halfway with water and shake well.
  2. Vinegar and essential oil spray: Add 8 ounces of white vinegar to a 16-ounce spray bottle. Add 6 drops of peppermint essential oil and 4 drops of rosemary essential oil. Shake the bottle to mix the contents and spray it onto your plants.
  3. Garlic and cayenne pepper spray: Blend eggs, milk or yogurt, garlic, and cayenne pepper with two to three cups of water. Strain the mixture and spray it on your flowers to repel deer.

How Deer Repellent Sprays Work

Deer repellent sprays work by making your yard smell or taste bad to deer, deterring them from entering and feeding on your plants. They use ingredients like putrefied eggs, predator urine (often coyote), blood products, garlic, and essential oils like peppermint and rosemary.

Best Time to Apply Deer Repellent Sprays

The best time to apply deer repellent sprays is early in the morning or late in the evening when deer are most active. You should also reapply the spray after a heavy rain or at least once a week during peak deer seasons.

In conclusion, there are a variety of commercial and homemade deer repellent sprays you can use to protect your flowers. Remember to rotate the use of different products and reapply them regularly for the best results. With a little effort and persistence, you can keep your garden beautiful and free of deer.
