Maiden pink · Dianthus deltoides

Why are there bugs on my Dianthus deltoides?

It is less common for Maiden pinks to have pests, but they can occasionally attract aphids or spider mites if the plant is stressed. Check the undersides of the leaves and the stems for tiny insects or webbing.

Check these first

  1. Inspect the undersides of the leaves with a magnifying glass.
  2. Look for sticky residue or webbing on the stems.
  3. Check if the plant is getting enough water to stay healthy.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see clusters of tiny green or black insects on the new growth or flower buds. They suck the sap and cause distorted leaves.

    What to do: Spray the plant with a steady stream of water to knock them off. If they persist, apply insecticidal soap once a week until they are gone.

  2. Spider Mites

    Possible

    How to tell: Look for fine, silky webbing between the stems and tiny yellow stippling on the leaves. These pests thrive in hot, dry conditions.

    What to do: Increase the humidity around the plant and wash the foliage with water. Use neem oil every 7 to 10 days if the infestation continues.

When to worry

You should worry if the plant shows signs of wilting or if the leaves start turning yellow and dropping. A few bugs are manageable, but a heavy infestation can weaken the plant quickly.

Stopping it coming back

Keep your Dianthus healthy by providing full sun and proper airflow. Regularly inspect your plants during the growing season to catch issues early.
