Managing Spittlebugs on Foster Holly

Black, half-inch insects with orange stripes on 'Foster' holly are adult spittlebugs. These pests favor 'Foster' and 'Nellie Stevens' hollies but avoid 'Burford' and yaupon holly. In spring, nymphs produce distinctive "spit globs" on grass and garden plants.

Damage and Control

While adults feed heavily on holly leaves, the plants typically tolerate the damage without long-term harm. If yellowing leaves become excessive, apply a garden insecticide. Otherwise, monitoring is usually sufficient.

Prevention Tips

• Choose resistant holly cultivars for new plantings.
• Maintain plant health to improve tolerance.
• Spot-treat only if aesthetic damage is unacceptable.
