Non-Chemical Management
- Wash aphids from plants with a strong stream of water.
- Remove aphids by hand (when practical) to control small infestations.
- Natural predators and parasites, including ladybird beetles, lacewings, and parasitic wasps, help control aphid populations.
- 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.
