How to Get Rid of Ants on Coleus Plant

Updated: December 24, 2022

Coleus plants are a popular choice for gardeners due to their vibrant colors and easy care. However, ants can quickly become a problem and damage the plant. Ants feed on the sweet nectar produced by the plant, which attracts other insects like aphids that can also harm the plant. Fortunately, there are several ways to get rid of ants on a coleus plant.

Identify the Problem

Before treating your coleus plant for ants, it’s important to identify the severity of the problem. A few ants on your plant might not be a cause for concern, but if you notice an infestation, it’s time to act.

Check the leaves and stems of your coleus plant for any signs of aphids or other insects that might be attracting ants. Look for sticky residue or black sooty mold, which can be caused by honeydew secreted by aphids.

Natural Remedies

There are several natural remedies that can help get rid of ants on your coleus plant:

  1. Diatomaceous earth – Sprinkle food-grade diatomaceous earth around the base of your plant. This natural powder will kill the ants by dehydrating them.

  2. Cinnamon – Sprinkle cinnamon around the base of your plant or make a cinnamon spray by mixing one-part cinnamon with three parts water. Spray the solution directly onto the plant to deter ants.

  3. White vinegar – Mix equal parts white vinegar and water and spray it directly onto your coleus plant to kill any ants on contact.

  4. Peppermint oil – Mix a few drops of peppermint oil with water and spray it onto your plants. The strong scent will deter ants from climbing onto your coleus.

Chemical Remedies

If the natural remedies don’t work, there are several chemical options available:

  1. Insecticidal soap – Spray insecticidal soap directly onto your coleus plant to kill any ants or other insects. Make sure to follow the instructions on the label and avoid using it during hot or sunny weather.

  2. Ant bait – Place ant bait near the base of your plant. The ants will take the bait back to their colony, killing the entire nest.

  3. Pyrethrin spray – Pyrethrin spray is an effective insecticide that can kill ants on contact. However, it can also harm beneficial insects, so use it sparingly.


Prevention is key when it comes to getting rid of ants on your coleus plant:

  1. Keep your plant healthy – A healthy plant is less likely to attract pests. Make sure your coleus is getting enough water, sunlight, and nutrients.

  2. Prune regularly – Prune regularly to remove any damaged or dead leaves or stems that might attract ants.

  3. Remove any nearby ant nests – If you notice an ant nest near your coleus plant, remove it as soon as possible to prevent ants from climbing onto your plant.
