Heat versus chemical - why two quotes differ by thousands

For most routine interior treatments the rule is set by the product label, which is federal law - commonly re-entry once treated surfaces are dry. The widely circulated 'twelve hour' figure comes from agricultural worker protection standards and does not apply to homes. Fumigation is different and does require vacating. Ask the technician what will be applied and what the label requires.

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.

A liquid barrier treatment - trenching around the foundation and drilling through concrete to create a continuous treated zone - commonly runs 1,000-3,200 dollars for a typical home perimeter. Inspections run 100-300 and are often credited against the job or offered free as a promotion. Bait systems are priced differently and usually carry an annual monitoring fee.
