Carpenter ants can be a nuisance when they show up inside the house. If only 1 or 2 larger, wingless ants are found, they may simply be foraging for food with their nest located outside. However, if 20 to 25 large winged and/or wingless ants are found indoors in the daytime near one location, it is possible that the colony is well established in the home and may be causing serious damage.

For the most part in this section we deal with carpenter ant colonies found in trees in the yard. In a few months we will add the information you need for dealing with carpenter ants inside the home.
