Ants on Grapefruit Tree: Identify Before Treating

Small Ants on Citrus: Usually Harmless Honeydew Harvesters

Most ants on citrus farm aphids/scale for honeydew. They don't harm the tree. Carpenter ants nest in dead wood only—also not primary pests.

Trunk spray: Malathion (contact, washes off fruit safely).
Bait at base: Commercial ant bait (hydramethylnon, boric acid) – carried to nest, not absorbed by tree.

Neem oil repels but doesn't eliminate colonies. Avoid soil drenches near edibles. Identify ants first—many are beneficial predators.
