Termites are insects with a very defined social strata. A mature termite colony may number in the millions, with each member fulfilling a defined biological role. The castes, not including nymphs (immature termites), are called workers, soldiers and reproductives. Typically, a queen and king reside in a mature colony. Winged adults are referred to as “swarmers.” They emerge from the colony and take flight (swarm) during certain seasons of the year, usually late winter to early spring. This marks the beginning of the termite reproductive cycle, as the swarmers are the primary reproductives. Swarming is also significant, as it is during this time that they are most likely to be spotted by humans.
People often confuse swarming termites with flying ants. There are distinctive differences, however. In order to discern a termite from a winged ant, compare the visual biological differences: Ants have a narrow, wasp-like waist (more “cinched” in the middle of the body). Termites do not have a defined waist. Ant wings are about equal to the body size, with the fore and hind wings of unequal length. Termites have four wings of equal length that are nearly twice as long as their bodies. Ant antennae are L-shaped, with a “bend,” while termite antennae are straight. Leading indicators of a termite infestation of the home are scattered, discarded wings on floors and window sills. Other visual evidence is their earth-colored mud tubes (protective tunnels constructed by termites for travel), which are often found in damp basement corners, walls, wooden support beams, posts, doors and window trim. The extensive structural damage termites inflict may go largely unnoticed for lengthy periods of time, as the infested building appears structurally sound from the outside. If you suspect an infestation or wish to take preventative measures as a homeowner, contact a pest control company to conduct a professional inspection.
