Aphids on Roses: Sticky Leaves and Simple Control

That Waxy Shine Is Honeydew

The sticky, shiny coating on leaves and buds in El Paso is aphid honeydew—excrement from colonies of tiny (1/8″), soft-bodied insects feeding on new growth. Ants farm them for this sugar-rich secretion.

Why Aphids Are Problematic

• Distort leaves and buds.
• Transmit viruses between plants.
• Weaken plants by sucking sap.

Control Steps

1. Blast with water – Strong hose spray knocks off most aphids; they can't climb back.
2. Insecticidal soap or neem oil – Thorough coverage, especially undersides; repeat in 5–7 days.
3. Safer's Insecticidal Soap – Excellent low-toxicity option.
4. Encourage beneficials – Lady beetles, lacewings, syrphid flies naturally control aphids.

Prevention

Avoid excessive nitrogen fertilizer (promotes soft, aphid-attracting growth). Monitor weekly in spring; early intervention prevents explosions.
