Identifying and Controlling Black Cherry Aphids on Your Tree

Identifying and Controlling Black Cherry Aphids on Your Tree

Small bugs and black sticky residue (honeydew) on new cherry growth likely indicate black cherry aphid infestation. These pests cluster on tender shoots, causing leaf curl and sooty mold.

Control Options

• Natural predators: Lady beetles, lacewings, and parasitic wasps often keep populations in check.
• Horticultural oil or insecticidal soap: Apply when aphids are active, following label directions.
• Strong water spray: Dislodges aphids; repeat as needed.

For severe cases or large trees, consult a certified arborist or your local extension service. The Washington State University guide provides detailed management strategies.
