The two main bed bug treatment approaches are heat and chemical. Both work — but they work differently, cost differently, and require different prep. Here's how to decide.
How heat treatment works
Specialized heaters raise the temperature of the treated space to 120–140°F and hold it there for several hours. Bed bugs die at sustained 118°F, including the eggs that resist most chemicals. One properly executed heat treatment typically eliminates the entire infestation in a single visit.
How chemical treatment works
Licensed technicians apply targeted, EPA-registered residual insecticides to harborage areas — mattress seams, baseboards, furniture joints, and wall voids. Because eggs survive most residuals, chemical treatment usually requires 2–3 visits over 4–6 weeks to catch newly hatched bugs.
Cost comparison
Heat is typically 1.5–2× the cost of a chemical treatment because of the equipment and labor involved, but you're done in one day. Chemical is cheaper per visit but you're paying for multiple visits.
Prep requirements
Heat requires removing heat-sensitive items: candles, aerosols, electronics that can't handle the temperature, certain medications, and pets. Chemical requires bagging clothing, washing bedding, and pulling furniture from walls — more sustained effort over a longer window.
Which one is right for you
Heat is best when you need fast results, the infestation is heavy, or you're in a single-family home where you control the whole space. Chemical is often a better fit for apartments where adjoining units may be a reinfestation source, for sensitive items that can't tolerate heat, or for tight budgets.
