A question on PREMISE75 for termite experts (Howe: house, linear)

[SpaceNeedle]

A termite technician applied termite treatment on our property by spraying PREMISE 75 around the outer foundation walls.

However, we found the instructions from the manufacturer (Bayer Environment Science) indicating that the treatment must be made by trenching.

1. OUTER FOUNDATION WALLS: Application must be made by trenching, or where appropriate (see below) by trenching, or trenching
and rodding from the bottom of the trench, around the outside of the foundation walls. When trenching, excavate a trench along the
outside foundation that is about 6 inches wide and 6 inches deep. Apply 4 gallons of solution (see APPLICATION VOLUME) per 10
linear feet, per foot of depth to provide a uniform vertical treated zone.
• For shallow foundations, one foot or less of depth, dig a narrow trench that does not exceed 6 inches wide and 6 inches deep
along the outside of the foundation walls, being careful not to dig below the bottom of the footings. For foundations with
exposed footings, dig a trench alongside the footing taking care not to undermine the footing.
• For basements and other foundations deeper than one foot, the application must be made by trenching and rodding from the
bottom of a shallow trench. When rodding, rod holes must be spaced in a manner that will allow for a continuous treated zone,
not exceed 12 inches, to be deposited along the treated area. Rod holes must not extend below the footing. Rodding depth
should be to the top of the footer, or to a maximum depth of 4 feet, or according to state or local regulations.
For all applications, apply the solution into the trench and mix with the excavated soil as it is replaced into the trench. Use a lowpressure
spray to treat soil that will be replaced into the trench after rodding. Mix spray solution with the soil as it is being replaced in the trench.

Can any termite experts out there explain to me if *spraying* would be equally effective for AZ soils?

I posted this question on AZ forum but only received 1 reply so I was hoping there were more termite experts in Texas forum.

Thank you.

If he just treated your house without trenching, then that treatment will not do anything for termites it would just work for general pests ants,earwigs, etc.
