Azalea Mealybugs: White Sacs and Crawling Bugs

Identifying the Infestation

Central NJ azaleas with white sacs on nearly every leaf underside, bugs on branches, leaf drop/browning/spotting—classic mealybugs. The sacs are egg masses; crawlers spread to new growth.

Organic Control Choice

Neem oil preferred over synthetics:

• Absorbs into leaves—rain-fast, residual.
• Repels reinfestation.
• Organic, safe for beneficials.
• Disrupts mealybug life cycle.

Why Neem Beats Contact Sprays

Mealybugs hide in leaf axils, under bark—contact sprays miss them. Systemic action of absorbed neem reaches hidden feeders. Apply thoroughly; repeat in 7–10 days.
