Why are there bugs on my chili pepper plant?

Aphids are the most frequent visitors to chili plants, often clustering on the tender new growth. Look closely at the undersides of leaves for tiny green or black insects.

Check these first

  1. Inspect the undersides of new leaves.
  2. Look for sticky honeydew on the foliage.
  3. Check for ants patrolling the stems.

Likely causes

  1. Aphid Infestation

    Most likely

    How to tell: You see small clusters of soft bodied insects and sticky residue on the leaves.

    What to do: Spray the plant with a strong stream of water to knock them off. If they persist, apply insecticidal soap or neem oil every 5 to 7 days.

  2. Ant Activity

    Possible

    How to tell: You notice ants crawling up and down the stems of your plant.

    What to do: Ants often protect aphids, so remove the aphids first. Use a sticky barrier around the base of the stem to keep ants away.
