Where do carpenter ants often nest?

Carpenter ants are known for their nesting habits, which predominantly revolve around soft, decayed wood. These insects have a preference for wood that has been compromised by moisture or decay, making it easier for them to excavate and create nests. Unlike termites, which consume wood for sustenance, carpenter ants typically remove wood to create their nests, leaving behind a distinctive sawdust-like material as they tunnel through.

This characteristic behavior is essential for structural pest control professionals to understand, as it not only helps in identifying infestations but also in implementing effective control measures. In residential settings, common nesting sites include areas that are damp or have experienced water damage, such as around leaky roofs, windows, or plumbing fixtures. Recognizing the significance of decayed wood in carpenter ant nesting can aid in the prevention and treatment of infestations.
