Carpenter Ants in Old Apple Tree: Bait, Don't Spray

Carpenter Ants in Apple Tree: Nest in Decay, Not Cause

Ants nest in pre-existing rot, not sound wood. They don't harm the tree but may invade nearby structures.

Baits (Terro, boric acid/sugar water): Slow but colony elimination. Safe for fruit.
Direct nest spray (bifenthrin, permethrin) only if nest exposed during work.
No treatment needed for tree health.

Ants are a symptom of decay, not the cause. Fix moisture/drainage issues to slow rot.
