Woolly Aphids on Apple Tree: Soap Spray Control

Young apple tree with white cottony masses on new branches: woolly aphids. The waxy coating protects them, but insecticidal soap penetrates it.

Spray insecticidal soap (or homemade: 1 tsp mild liquid soap + 1 quart water) every 3–4 days.
Wipe off reachable colonies with fingers.
Persist; they will return but soap suppresses population.
Neem oil also effective.

Woolly aphids rarely kill trees but reduce vigor. Consistent spraying during active growth keeps them manageable.
