I worry about finding a few carpenter ants
inside our house?"
A: Usually not. At
certain times of the year carpenter ant nests
located outside but near houses release large
numbers of winged ants (left, above) that are
capable of flying in through open doors and
windows. The presence of these ants indoors is no
reason for concern. If more than a few
ants are found indoors, however, there may be a
nest, or nests, in the walls.

indicate a nest located inside the home.
Otherwise, finding ants outside should be no
concern (see Related
