What distinguishes carpenter ants from termites?

The correct distinction between carpenter ants and termites lies in the structure of their antennae. Carpenter ants possess elbowed antennae, which are bent or have an angle, giving them a characteristic jointed appearance. This feature is a key identifier as it is exclusive to ants within the insect classification.

In contrast, termites have straight, bead-like antennae that do not exhibit this elbowed characteristic. Recognizing this feature is particularly important for pest control professionals and homeowners alike, as it plays a significant role in correctly identifying the type of infestation, which ultimately affects the choice of treatment or prevention methods.

The other choices do not accurately represent the primary differences between these two insects. For instance, both carpenter ants and termites may have wings at certain life stages, and their sizes can overlap. Additionally, while the body shape can be a distinguishing factor in some contexts, it is not as definitive as the antennae structure. Understanding these differences is crucial for effective identification and management of these common wood-dwelling pests.
