At what pressure should liquid termiticides be used when trenching and treating?

Using liquid termiticides at a pressure of 25 psi during trenching and treatment is recommended for several reasons. This pressure level strikes a balance that ensures effective distribution of the termiticide into the soil while minimizing the risk of creating excessive mist or drift. A pressure of 25 psi allows for good penetration into the soil where termites may nest, facilitating adequate coverage in the treatment zone.

Moreover, using lower pressure helps prevent the termiticide from being sprayed too finely, which can result in loss to the air as droplets are carried away by wind, or can result in uneven application. Conversely, higher pressures may lead to potential pesticide drift and could create a situation where the termiticide does not effectively reach its target area, thus not protecting the structure as intended. Therefore, maintaining the application pressure at 25 psi is considered best practice for optimal efficacy and safety in termite control operations.
