How To Keep Ants Away from Peonies

Ants 7

Peonies are cherished for their large, vibrant blooms and sweet fragrance. However, one common predicament that peony enthusiasts often face is the presence of ants. While it’s important to note that ants do not harm peonies, some people may still wish to keep them away, especially when cutting peonies to bring indoors. In this comprehensive guide, we will explore effective ways to keep ants away from your peonies.


To keep ants away from peonies, you can use natural remedies such as a peppermint oil spray, sprinkling cinnamon, companion planting with ant-repellant plants, homemade ant traps, and a strong water spray. However, it’s important to note that ants do not harm peonies and their presence is usually temporary. Always test any solution on a small part of the plant first to ensure it does not harm the peonies.

Understanding the Ant-Peony Relationship

Before we delve into the solutions, it’s crucial to understand the relationship between ants and peonies. Ants are attracted to the nectar that peony buds secrete. The nectar serves as a food source for ants, and in return, the ants protect the flowers from other insects that feed on them. This mutualistic relationship benefits both parties.

Natural Remedies to Deter Ants from Peonies

  1. Peppermint Oil Spray: Mix 2 to 3 tablespoons of peppermint oil with 1 US quart (0.95 L) of water in a spray bottle. Spray the mixture on the stems of the peonies and around the bushes. The strong scent of peppermint is known to deter ants.
  2. Cinnamon: Sprinkle a small amount of cinnamon on the buds or petals or place a cinnamon stick near the peonies. Ants have an aversion to cinnamon, making it an effective deterrent.
  3. Companion Planting: Plant ant-repellant plants such as geraniums, mint, garlic, and calendula near your peonies. These plants emit scents that ants dislike.
  4. Homemade Ant Traps: Cut a circle out of a piece of paper, smear one side with petroleum jelly, and place it around the stem of your peony plant. Ants attempting to climb the plant will get stuck in the petroleum jelly.
  5. Water Spray: A strong stream of water can temporarily get rid of ants on the bushes. However, this is a short-term solution and may not stop more ants from reaching your peonies.

Precautions When Using Natural Ant Repellents

When using natural ant repellents such as peppermint oil, it’s important to take a few precautions. Test the solution on a small area of the plant first to ensure it doesn’t harm the peonies. Keep the solution out of reach of children and pets, and avoid getting it in your eyes or on your skin, as it can cause irritation.

Other Insects that are Attracted to Peonies

Apart from ants, peonies can also attract thrips and aphids. However, the presence of ants on the peonies can help protect the plants from these harmful insects.


While ants do not harm peonies, some people may still want to keep them away. The methods mentioned above can be effective in repelling ants. However, remember that the presence of ants on peonies is only temporary and does not harm the flowers. Therefore, the use of an insecticide is unnecessary. By understanding the relationship between ants and peonies and using natural remedies, you can enjoy your beautiful peonies without the worry of ants.
