What heat treatment actually does
Whole-room heat raises the air temperature of a space until every harbourage in it — mattress seams, bed frames, behind skirting, inside furniture — reaches a temperature bed bugs cannot survive. Bed bugs and their eggs die within 90 minutes at 118°F (48°C) and immediately at 122°F (50°C) (University of Minnesota Extension). To get there throughout a room, air is typically held at 135–145°F (57–63°C).
The reason this matters in New York is eggs. The US EPA notes that controlling bed bugs takes time and patience because they reproduce quickly and their eggs are resistant to many methods of pest control, both chemical and non-chemical (US EPA). Heat does not leave that gap: at lethal temperature it takes the eggs with the adults.
Heat vs conventional insecticide for a NYC apartment bed-bug job
| Factor | Whole-room heat treatment | Conventional / chemical treatment |
|---|---|---|
| Effect on eggs and all stages | Lethal to bed bugs and eggs — they die within 90 minutes at 118°F (48°C) and immediately at 122°F (50°C) (UMN Extension) | Eggs resist many chemical and non-chemical methods, so survivors hatch after treatment (EPA) |
| Typical visits to resolve | Can kill all stages in a single heated session if target temperatures are held room-wide | Very few infestations are eliminated by one treatment; multiple visits are usual (EPA) |
| How it works | Room air typically held at 135–145°F (57–63°C) until the whole space reaches lethal temperature (UMN Extension) | Relies on residual and contact insecticides reaching every harborage |
| NYC multi-unit reality | Treats one unit thoroughly, but bugs can still arrive from adjacent apartments through wall and pipe gaps (UMN Extension) | Same risk — IPM, monitoring and inspecting adjacent units stay essential (EPA / UMN) |
| What both require | Resident prep and post-treatment monitoring for survivors | Resident prep, IPM and diligent monitoring; success depends on resident participation (EPA) |
What heat cannot do
Heat treats the space you heat. In a Brooklyn brownstone or any multi-unit building, bed bugs spread by hitchhiking and readily travel 5 to 20 feet from a harbourage to a host (US EPA), and can arrive from adjacent apartments through wall and pipe gaps. A thoroughly heated unit next door to an untreated one is not a finished job — which is why inspection of neighbouring units, monitoring, and an IPM plan sit around the heat, not instead of it.

Common questions
What temperature kills bed bugs?
Bed bugs and their eggs die within 90 minutes at 118°F (48°C) and immediately at 122°F (50°C), per University of Minnesota Extension. To reach that everywhere in a room, air is typically held at 135–145°F (57–63°C) until the whole space — including inside furniture and wall voids — comes up to lethal temperature.
Does heat treatment kill bed bug eggs?
Yes, and that is the main practical difference from conventional insecticide. University of Minnesota Extension reports heat is lethal to bed bugs and eggs at those temperatures. The US EPA notes that bed bug eggs resist many chemical and non-chemical control methods, which is why survivors can hatch after a chemical-only treatment.
Is one heat treatment enough?
A heated session can kill all life stages in one visit if target temperatures are actually held room-wide. But in a NYC building, bed bugs can still arrive from adjacent apartments through wall and pipe gaps, so monitoring after treatment and inspecting neighbouring units stay essential.
Do I need to prepare my apartment for heat treatment?
Yes. Both heat and chemical treatment require resident preparation and post-treatment monitoring for survivors. The US EPA is explicit that success depends on resident participation.
