Non-Chemical Management
- Wash aphids from plants with a strong stream of water.
- Hand-wipe or prune to control small, localized infestations (when practical).
- Encourage aphid predators and parasites, including ladybird beetles, lacewings, and parasitic wasps. Avoid use of broad-spectrum insecticides which may kill these beneficial insects.
- Control honeydew-feeding ants, which may protect aphid colonies.
- Provide proper nutrition. High levels of nitrogen in the foliage encourage aphid reproduction. Switch to a slow-release or low-nitrogen fertilizer.
- Inspect plants closely for presence of the pest prior to purchasing or transplanting.
