What minimum distance should all voids in bearing walls be treated from evidence of subterranean termite infestations?

The correct choice is based on the guidelines established for the management and treatment of subterranean termite infestations. In this context, the minimum distance of 4 feet is critical for effective pest control.

Subterranean termites are known to travel significant distances in search of food, typically moist wood and cellulose materials. When a termite infestation is detected, it is important to treat any voids in bearing walls to interrupt their potential pathways and for preventative measures. By establishing a treatment zone of 4 feet from any evidence of infestation, it provides a buffer zone that ensures thorough coverage of possible termite entry points, thus enhancing the effectiveness of the treatment and reducing the chances of future infestations.

This standard is guided by best practices to ensure that pest management efforts are comprehensive and minimize risks associated with termite damage. Adhering to this distance plays a critical role in pest management policies and procedures within the realm of pest control.
