Spittlebugs on Virginia Pine: Foam, Insects, and Control Options

White, foamy masses on Virginia pine trunks up to 7 feet high are the protective spittle of spittlebug nymphs. The nymphs feed on sap, and heavy infestations can cause yellowing and stunting. The foam is conspicuous but the insects inside are small and hidden.

Control Methods

Conventional: Apply contact insecticides (permethrin, acephate) when spittle masses appear in spring.
Organic: Atomic Grow foliar spray deters feeding and improves plant health.
Cultural: Strong water jets can dislodge nymphs; repeat weekly.

One generation per year; treatment in April-May prevents summer damage. The foam itself is harmless and washes off.
