Orange Bumps on Oak Leaves in Florida: Likely Gall Insects

Oval, bumpy, orange 1/4-inch growths on oak leaves in Florida are almost certainly galls from tiny wasps. Cosmetic only—no harm to mature tree.

Check

• Cut one open: egg/larva inside confirms gall.
• Rake fallen leaves; destroys overwintering stages.
• No spray needed.
• Send photo if unsure.

Regular watering keeps tree vigorous.
