Aphid control

Aphid control. Aphids keep numbers on their side: They crowd on many of our garden plants and houseplants. Last Seen in the Vicinity of North America.


Both adults and nymphs suck plant sap from most fruits, vegetables, flowers, ornamentals, nuts, herbs, fruit and shade trees, and conifers. Their feeding often causes deformation leaves, buds, and flowers; infested leaves and flowers may drop. Sweet honeydew on the underside of the leaves is the aphid secretions. Honeydew attracts a variety of other types of insects. Some aphids spread plant viruses as they feed.

Description of insect

Adults are soft, pear-shaped insects, 2,4 to 3,3 line long, with 2 short cornicles projecting backward from the tip of the abdomen. They have long antennae and may be green, yellowish, black, pink, or powdery gray in color. They can be either winged or wingless. Winged females appear in response to crowding or to changes in the host plant. Large transparent wings cover her back aphid. Nymphs resemble adults, but are wingless and smaller.

Crime Prevention

Maintain healthy plant growth, but do not over fertilize with nitrogen.


Attract native predators and parasites by planting pollen and nectar plants.

Release purchased aphid midges, lady beetles (these tend to fly away, so they’re more effective for greenhouses), lacewings, or parasitic wasps. Consult suppliers to find out the best species and release rates for your local conditions.


Spray plants with a strong stream of water to knock aphids off.

Spray insecticidal soap, neem extract, summer oil (on tolerant plants), homemade garlic sprays, or, as a last resort, pyrethrins.

Lavender and thyme repel aphid.
