Pretreatment is coordinated with construction. The useful homeowner question is not simply whether treatment happened, but what was documented and what later work may affect it.
Ask for the treatment record
Arizona regulates new-construction termite treatment. Owners should retain documentation identifying the applicator, treatment date, property, method or product information supplied, and any warranty or follow-up terms. If the builder holds the records, request copies before closing or as soon as a question appears.
Construction timing matters because slabs, foundations, backfill, final grading, plumbing penetrations, and attached features may be treated at different stages. A generic statement that the lot was sprayed is not a substitute for records showing what was done at your home.
Changes after construction deserve attention
Patios, room additions, utility trenches, landscaping, irrigation, planters, soil movement, and exterior repairs can alter conditions around a previously treated structure. Before starting major work, show the termite records to the contractor and ask the pest-control provider whether the project affects monitoring or coverage.
Final grade and the visible foundation edge also matter for future inspection. Soil, decorative rock, stucco, foam, or landscaping that obscures the transition can make tubes harder to see. Owners can keep that area observable without attempting pesticide work themselves.
Check for existing coverage before paying for new treatment
If your home was treated when it was built, find the original paperwork before paying for another treatment. The previous work may still have coverage.
Photograph the new evidence and contact the company named in the pretreatment record or warranty. Ask whether it will inspect the property and whether retreatment is included. If the company is unavailable or the coverage has ended, give the records to the new inspector.
