PureHeat

PureHeat isn't a general exterminator — it's built around one problem: bed bugs. The company says it got started in 2008 after its founders spent over $40,000 on their own infestation before discovering heat as the fix, and it now offers a one-day heat treatment across New England with a guarantee of zero live bugs after the visit. Beyond that self-description, there isn't much of a public track record yet. Its Google page carries a single 5-star rating, which is too little to say anything meaningful about how consistent the work is or how recent customers have felt about it. Anyone considering PureHeat should ask directly about pricing and how the guarantee is honored if bugs return, and request references, since there isn't a body of independent reviews to lean on yet.
