| Ants in tub. Nowhere else. Any idea why? Black carpenter. Pennsylvania.

Carpenter ants.... you mean the big ones? The little
ones tend to travel this time of year, for a week
or two. We had a troop of them coming up inside the
house last year and marching into the 2nd floor tub.
They must have been confused by some shampoo
scent. But they're harmless and stopped roaming
As BQ340 said, the big ones are
a sign of rot. They don't cause harm, per se. They'll
tunnel in the wet, damaged wood but, unlike termites,
they don't actually represent a threat. Actually
they're a help because they let you know there's
trouble before it gets worse. Carpenter ants will only
eat wet wood, so you probably have a leak in the
tile somewhere that's been going for awhile. You
should consider doing whatever's necessary to check
it out. If it's rotting it should be dealt with now. Once
it's fixed the ants will leave. No need to treat them
in any way.
