According to NC regulations, what depth is required for establishing a continuous termiticide barrier?

To establish a continuous termiticide barrier according to North Carolina regulations, a depth of 30 inches is required. This depth is critical for effectively protecting structures from termite infestations. By applying the termiticide to this depth, it creates a protective zone that targets termite activity in the soil surrounding the foundation, which is where subterranean termites typically reside.

The requirement for this specific depth is based on industry standards and research showing that a 30-inch barrier significantly reduces the likelihood of termites entering the structure. It ensures that the chemical remains effective against termite activity by being applied deep enough to intercept any potential infestations from the ground. Therefore, maintaining this recommended depth is essential for the long-term efficacy of the treatment and the protection of the structure against these damaging pests.
