White Bugs on Rose Leaves: Aphid Identification & Control

Small white bugs covering tops and bottoms of leaves? Almost certainly aphids — spring's #1 rose pest.

Immediate Mechanical Control

• Jet spray from hose — knocks 90% off instantly. Repeat every 2-3 days.
• Hand wipe/squish — effective for small infestations.

Chemical Backup

Insecticidal soap or horticultural oil — spray tops AND bottoms of leaves. Weekly until gone. Spring-only problem usually — disappears with summer heat.

Prevention

• Don't over-fertilize with nitrogen
• Encourage lady beetles, lacewings
• Monitor weekly in April-May

Aphids are annoying but rarely threaten established roses. Stay calm, spray water.
