Ashoka tree · Saraca asoca

Why are there bugs on my Ashoka tree?

Seeing tiny insects on your Ashoka tree is usually a sign of aphids. These pests love to cluster on the tender new growth to feed on the sap. Check the undersides of your leaves first to confirm their presence.

Check these first

  1. Inspect the undersides of new leaves for small clusters of insects.
  2. Check for a sticky substance called honeydew on the foliage.
  3. Look for ants moving up and down the trunk.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: You will see small green or black insects clustered on new shoots and sticky residue on the leaves. The new growth may look stunted or distorted.

    What to do: Spray the affected areas with a strong stream of water to knock them off. Follow up by applying neem oil or insecticidal soap every 5 to 7 days until they are gone.

  2. Ant activity

    Possible

    How to tell: Ants often patrol the branches to protect aphids for their honeydew. If you see a trail of ants, they are likely farming the pests.

    What to do: Eliminate the aphids first, as the ants will lose interest once their food source is gone. You can also place a sticky barrier around the trunk to stop ants from climbing.

When to worry

It is serious if the infestation covers the entire tree and causes significant leaf curling. A few stray bugs are normal and easily managed.

Stopping it coming back

Keep your tree healthy with proper watering and check the new growth weekly for early signs of pests.

Questions people ask

Will aphids kill my Ashoka tree?
A small number of aphids rarely kills a mature tree. However, a heavy infestation can weaken the plant and stunt its growth.
Can I use dish soap to kill them?
