We're renting a new place in Brooklyn - saw enough ants when we first moved in (less than a month ago) that we had someone come and spray for bugs. Saw this tonight in an unused, upstairs back bedroom (not near any food). I'm worried these are carpenter ants as we only see them at night. Sprayed a bunch and alerted our landlord, but are we screwed? This is a gross nightmare.
