What Are Aphids?
Aphids are small sucking insects that feed on leaves and shoots. They do not cause major damage to most well-established trees but can cause unsightly symptoms.
Signs of Infestation
Here are the most common symptoms of an Aphid infestation:
- Yellowing, wilting, and curling leaves
- Sticky liquid (honeydew) on lower leaves, lawn furniture, and sidewalks
- Dense, black mold growth (sooty mold) on lower leaves and nearby surfaces
Insect Control
Naturally occurring beneficial insects usually cut down Aphid populations to the point where they do not present a major problem for the tree.
Before spraying for Aphids, look for natural predators like Ladybugs and Lacewings. If you have a major infestation and no natural predators in sight, consider natural pest control methods like introducing Ladybugs or other predatory insects.
You can also spray the leaves of sturdy trees and shrubs with water from a garden hose to remove aphids. The aphids are unlikely to find their way back to the tree.
The most effective chemical method of aphid control is insecticidal soap. This soap is the safest insecticide available. You will have to spray multiple times and soak the leaves well. Horticultural oil, like neem oil, can also help. When using neem oil or insecticidal soap, you must ensure maximum leaf coverage for the method to work.

Can I prevent Aphids from getting into my trees?
You can use ground covers around the base of your trees to deter aphids. Soil sprays can also work in extreme cases. Finally, a good rinse with a garden hose will prevent Aphids from becoming established.
