PureHeat

PureHeat does one thing: a one-day heat treatment that clears a house of bed bugs. The company says it started in 2008, after its founders lived through a costly infestation themselves and licensed the heat-treatment process for New England. It guarantees zero live bed bugs after the treatment. That is PureHeat's own promise, so get the terms in writing — how long it runs, what counts as a re-infestation, and whether a return visit costs anything. If you would rather have the whole place treated in a single day than work through a schedule of sprays and return trips, this is the outfit built for that. Ask what preparation they expect from you before the crew arrives, and confirm the company's pest-control licensing and insurance.
