How many gallons of termiticide are required per foot of depth for trenching along the foundation?

The requirement of 4 gallons of termiticide per foot of depth for trenching along a foundation is based on established pest control practices that ensure an effective barrier against termites. When treating the soil around structures, proper application rates are critical to prevent termite intrusion.

Using 4 gallons per foot provides sufficient application to create a continuous barrier, allowing the termiticide to properly penetrate the soil and remain effective. This is particularly important because termites can travel through the soil, and an adequate amount of termiticide is necessary to ensure that the solution is evenly distributed and persistent enough to deter or kill any termites that may come into contact with it.

In contrast, other proposed amounts like 2, 3, or 5 gallons per foot either may not provide adequate coverage or could lead to over-application, which may not be environmentally sound or cost-effective. Therefore, 4 gallons per foot represents the standard for achieving reliable protection in termite management.
