Some will claim that pest control is an ancillary service not governed by the SOP or Ethics. I say NEVER cross the line of perceived ethics. One or the other, only. It is NOT the same as Radon testing, BUT, it is exactly the same as Radon mitigation! See the difference?
The InterNACHI member shall not perform or offer to perform, for an additional fee, any repairs or associated services to the structure for which the member or member’s company has prepared a home inspection report for a period of 12 months. This provision shall not include services to components and/or systems that are not included in the InterNACHI Standards of Practice
I would think if you have a state license for home inspection and pest control, this still applies.
