The two bond types, and the one question that tells them apart

Because they are quoting different products. Chemical treatment runs 200-400 dollars per room and usually needs two to three visits weeks apart; whole-room heat treatment runs 400-900 per room but is typically one session with equipment on site. Whole-job totals commonly land at 1,000-2,500, with severe cases higher.

For many common pests, yes - the EPA publishes consumer guidance and hundreds of products are available to the public, including for bed bugs. The work that is legally restricted to certified professionals is fumigation, which uses restricted-use products. The honest dividing line is severity and structure: a visible ant trail is a different problem from a termite colony in a foundation.

Yes - and this is one of the few home services where that is genuinely true nationwide. Applicator certification is required under federal pesticide law and administered by each state, usually through the agriculture department, though some states use a dedicated board or the health department. Exam fees, insurance and bond requirements differ substantially by state. This site links to each state's own licence lookup.

Four: what exactly is being treated and with what method; how many visits are included and what a return visit costs; what the agreement term, renewal price and cancellation cost are; and what the guarantee obliges them to do if the pest comes back. Companies that answer all four in writing are rarely the ones that cause problems later.

There are two types and the difference is enormous. A retreatment-only bond obliges the company to treat again if termites return but, in the words of state agriculture regulators, does not obligate it to repair, replace or correct any damage the termites caused. A retreatment-plus-damage bond additionally covers structural repairs up to a stated cap. Ask which one you are being offered, in writing.
