In nature, carpenter ants nest in the logs and stumps of decaying trees. Their job is to help decompose those trees as part of the cycle of life. It's no surprise then that they are attracted to other forms of wet and rotting wood, such as wood on your deck that's damp from a damaged gutter.
Carpenter ants are starting to become more and more active with the increasingly warmer weather in the Greater Pittsburgh area. With that, you need to arm yourself with all the knowledge you can to defeat these damaging ants.
