When drywood termite damage is spread across multiple wall sections or floors, spot treatment can't reach every colony — tent fumigation with sulfuryl fluoride is what clears the entire structure at once. State fumigation licensing is separate from general pest control licensing, and it's worth confirming any company quoting tenting work actually holds it before you sign anything.
A licensed fumigator walks the structure with you to explain exactly what tenting involves before you commit.
