What is the best control type for azalea lace bugs?

• A. Systemic insecticides.
• B. Contact insecticides only.
• C. Beneficial nematodes.
• D. Soap sprays.

Answer: (A)

Lace bugs on azaleas feed by sucking sap from the leaves and often hide on the underside, so reaching them with a spray that only sits on the surface is unreliable. A systemic insecticide is absorbed by the plant and moved throughout its tissues, including new growth, so the insects ingest the chemical as they feed. This provides more consistent and longer-lasting control of both adults and nymphs, even if they’re tucked under the leaf or on new growth. Beneficial nematodes target soil-dwelling pests, not lace bugs on foliage; soap sprays are contact-only and depend on perfect coverage, which is hard to achieve for lace bugs on azaleas. That’s why systemic insecticides are the best option here.
