Rose: Rose aphids
Rose aphids are small, soft, pinkish or green insects found on the succulent new growth, including buds and stems. White cast skins can also be present. Heavy aphid feeding can reduce the quantity and quality of the flowers produced.
Use Integrated Pest Management (IPM) for successful plant problem management.
Select non-chemical management options as your first choice!
- Avoid use of broad-spectrum insecticides which kill natural predators and parasites of aphids (including ladybird beetles and larvae, green lacewings and larvae, and parasitic wasps).
- Wash aphids from plants with a strong stream of water.
- Avoid overfertilization, as high nitrogen levels in the plant encourage aphid reproduction. Switch to a slow-release or low-nitrogen formula.
IMPORTANT: Visit Home and Garden Fact Sheets for more information on using pesticides.
- Apply oils in delayed dormant period to kill overwintering eggs.
- Apply one of the following when adult aphids are first observed.
- Thorough coverage of the foliage is important, including upper and lower leaf surfaces.
