Dusty Miller is a popular ornamental plant known for its silver-gray foliage. It is a hardy plant that can survive in different types of environments, making it a favorite of many gardeners. However, Dusty Miller plants are susceptible to infestations from ants, which can cause significant damage to the plant if left untreated. In this article, we will discuss how to get rid of ants on Dusty Miller plants.

The Problem with Ants on Dusty Miller Plants

Ants are attracted to Dusty Miller plants because they feed on the honeydew produced by aphids, mealybugs, and scale insects that commonly infest these plants. While ants themselves do not cause direct harm to the plant, their presence can indicate an infestation of other harmful insects. Furthermore, ants can protect these insects from natural predators such as ladybugs and lacewings, making it difficult to control the infestation.

How to Get Rid of Ants on Dusty Miller Plants

Getting rid of ants on Dusty Miller plants involves two steps: controlling the ant population and addressing the underlying insect infestation that attracts the ants.

Step 1: Controlling the Ant Population

There are several methods you can use to control ant populations on your Dusty Miller plants:

  • Soap and water: Mix equal parts of liquid dish soap and water in a spray bottle and spray the solution directly onto the ants. This method kills ants by suffocation and removes their pheromone trail, preventing other ants from following.
  • Diatomaceous earth: Sprinkle diatomaceous earth around the base of your Dusty Miller plant. This method works by dehydrating the ants and causing them to die.
  • Ant baits: Use ant baits containing boric acid or borax. Place the bait near ant trails, and the ants will carry the bait back to their colony, killing the entire population.
  • Cinnamon: Sprinkle cinnamon powder around the base of your Dusty Miller plant. This method repels ants due to its strong scent.

Step 2: Addressing the Underlying Insect Infestation

Controlling the ant population alone is not enough to solve the problem. You also need to address the underlying insect infestation that attracts the ants. Here are some methods you can use:

  • Prune affected leaves and stems: Cut off leaves and stems that show signs of infestation, such as yellowing, curling, or sticky residue. This method removes the source of honeydew, which attracts ants.
  • Use insecticidal soap: Spray your Dusty Miller plant with insecticidal soap, which kills aphids, mealybugs, and scale insects. This method is safe for the plant and does not harm beneficial insects such as ladybugs.
  • Release natural predators: Release natural predators such as ladybugs, lacewings, and parasitic wasps to control the insect population. You can purchase these predators online or from garden centers.
