What are the bugs on my English Lavender?

Lavender is generally hardy, but aphids and spittlebugs can sometimes move in. Check the new growth and stems to see if you have an infestation.

Check these first

  1. Look closely at the tips of the new growth.
  2. Check for sticky residue on the leaves.
  3. Look for white foam on the stems.

Likely causes

  1. Aphids

    Most likely

    How to tell: Small green or black insects clustering on the tender new growth or flower buds.

    What to do: Spray the insects off with a strong stream of water from your hose. If they persist, use a gentle insecticidal soap once a week.

  2. Spittlebugs

    Possible

    How to tell: You will see a white, frothy foam that looks like spit on the stems and leaves.

    What to do: Simply wash the foam off with a spray of water. They rarely cause real damage, so you do not need harsh chemicals.

When to worry

Small numbers of bugs are usually fine, but if the plant stops growing or the leaves start curling, you need to intervene. A few spittlebugs are rarely a cause for concern.

Stopping it coming back

Keep your plant healthy with plenty of sun and good airflow to discourage pests from settling in.

Questions people ask

Are these bugs going to kill my lavender?
Usually no. Aphids can weaken the plant if left unchecked, but spittlebugs are mostly just an eyesore.
Should I use pesticides?
Avoid harsh chemicals, as they can harm bees that love lavender. Water sprays or insecticidal soaps are safer choices.
