Heat versus chemical - why two quotes differ by thousands

Product labels carry legally binding directions covering application, ventilation and re-entry, and a professional is required to follow them. Tell the company in advance about pregnancy, infants, pets, fish tanks or asthma, and ask which products will be used and for the labels. Where a lower-risk approach exists - baits and targeted application rather than broadcast spraying - it is reasonable to ask for it.

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.

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.

Most states publish both a licence lookup and a complaint or enforcement record. Check the licence is current and in the right category for your job, then look for enforcement actions. Both links are on this site's state page, pointing at the regulator's own database rather than a directory we maintain.

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.
