True or False: Drywood swarmer activity is always indicative of an interior infestation.

The assertion that drywood swarmer activity is always indicative of an interior infestation is false. Drywood termites typically infest wood that is above ground and can create colonies within the wood itself, such as in structural timber or furniture. While swarmer activity can indicate an infestation, it does not exclusively signal that the infestation is contained entirely within an interior space. Swarmer termites can also emerge from wooden structures that are exposed to the exterior environment.

In many cases, swarmers may be found outdoors if there are drywood termite colonies residing within nearby wood or structures. Therefore, observing swarmers does not necessarily mean there is an active infestation within the interior of a building. Factors such as environmental conditions and the presence of nearby host wood may influence swarming behavior. This nuance is critical in understanding the nature and location of drywood termite infestations.
