- Check if the plant is near other infested plants.
Likely causes
Aphid infestation
Most likelyHow to tell: You will see clusters of small, soft bodied insects on the tender new stems and undersides of leaves. They often leave behind a sticky residue called honeydew.
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 until they are gone.
Weakened plant health
PossibleHow to tell: Plants that are stressed from heat or inconsistent watering are more susceptible to pest attacks. The plant may look generally tired or stunted.
What to do: Ensure your cilantro gets consistent moisture and is kept out of extreme heat. A healthy plant is much better at resisting bug invasions.
