Why are there bugs on my Fragrant sumac?

It is less common for Fragrant sumac to have major pest issues, but you might occasionally see aphids or scale insects. Check the undersides of the leaves and along the stems for small clusters of insects or sticky residue.

Check these first

  1. Inspect the undersides of the leaves for tiny insects.
  2. Look for sticky residue on the foliage.
  3. Check the stems for small, hard bumps.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see tiny green or black insects clustered on new growth or the undersides of leaves. They often leave behind a sticky substance called honeydew.

    What to do: Spray the plant with a strong stream of water from your hose to knock them off. If they persist, apply insecticidal soap once a week for 2 to 3 weeks.

  2. Scale

    Possible

    How to tell: These look like small, hard brown bumps on the stems or leaf veins that do not move. They suck sap and can weaken the plant over time.

    What to do: Scrape the bumps off gently with a soft brush or your fingernail. For larger infestations, dab the areas with a cotton swab dipped in rubbing alcohol.

When to worry

You should worry if the leaves start yellowing or dropping due to heavy feeding. A few bugs are usually manageable and not a sign of a dying plant.

Stopping it coming back

Keep your shrub healthy with proper watering and airflow to make it less attractive to pests. Avoid over fertilizing, as this encourages the soft growth that aphids love.

Questions people ask

Will these bugs kill my shrub?

Should I use systemic pesticides?
