What type of wood do carpenter ants avoid for nesting?

Carpenter ants generally prefer to nest in soft, moist wood. They are attracted to wood that is decayed or damaged, as it is easier for them to excavate. However, they avoid dry, high-density wood because it is harder to chew and manipulate for nesting purposes. This avoidance is crucial, as it aligns with their natural behavior of seeking materials that facilitate nest construction and maintenance. Carpenter ants thrive in environments where wood is damp and provides a conducive habitat, so high-density and dry wood does not meet their nesting requirements. Understanding the nesting preferences of carpenter ants is essential for effective pest management strategies, particularly in residential and commercial settings where structural integrity is a concern.
