If you see Drywood termite swarmers near a window or bright light, what can be inferred about the termite colony?

Swarmers, or alates, are the reproductive forms of drywood termites that leave their existing colony to mate and establish new colonies. When you observe these swarmers near a window or bright light, it typically indicates that the parent colony is located nearby. This behavior is common as swarmers are naturally drawn to light sources during their nuptial flights, which are crucial to the establishment of new colonies.

The presence of swarmers in immediate proximity suggests that they originated from a colony that is not only viable but also established enough to reproduce and send out swarmers. Identifying their location can help in controlling the infestation, as it may lead pest control professionals to the source of the termite activity.

The other options imply distances or circumstances that do not realistically correlate with the behavior and life cycle of drywood termites. For instance, if the colony were far away, swarmers would be less likely to congregate at that specific light source. Therefore, recognizing swarmers near bright light is a key indicator of the nearby presence of a termite colony.
