Heat versus chemical - why two quotes differ by thousands

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.

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.

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.

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.

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.
