Penn State College of Agricultural Sciences: Carpenter Ants
This information sheet
shows pictures of a carpenter ant worker and queen, and compares them to a termite, another social insect which also burrows through wood. If you want to get up close and personal with a carpenter ant and a termite, find out what to look for and how they differ. Learn the life history of the ant, and how to deal with an infestation. You’ll have to the stay up late to find them, though, because they like to forage between 10:00 p.m. and 2:00 a.m.
