Heat can clear bed bugs from a flat in a single day. The crew sets up professional heaters and fans, and wireless sensors report temperatures inside mattresses, sofa cushions and along the base of the walls. Most San Francisco households are back in their own beds that night.
Why Heat Works on Every Stage
Bed bugs and their eggs die when held at a high enough temperature for long enough, and no population has built resistance to heat. Crews typically keep the coolest spot in each room at about 120°F or more for a set time, flipping mattresses and moving cushions so no pocket stays cool.

- HeatRoom temperatures climb over several hours.
- HoldThe crew watches readings and shifts belongings so heat reaches every corner.
- Cool and checkRooms cool down, results are reviewed and edges may get a residual product.
Heat Treatment in San Francisco Buildings
Many Victorian and Edwardian flats have older wiring, so crews often check the electrical service before setup and may bring their own power. In a building with shared walls, the company should work with the owner so bugs pushed out by the heat do not simply move next door. Heat is popular with families who want nothing sprayed where a child sleeps.
Remove These Items First
- Candles, lipstick, crayons, aerosol cans, medicines, vinyl records, plants and pets.
- Anything else on the crew's list, such as some electronics or musical instruments.
- Clothing and bedding usually stay in the room; follow the crew's instructions.
- Open drawers and closets so hot air can move through.
Questions About Heat Treatment
Our building is always cold and foggy. Does that affect heat treatment?
It can add time. Cool rooms, drafty windows and uninsulated walls take longer to warm, which is why crews use sensors and keep heating until the coolest spot reaches the target.
Can I stay home during the treatment?
No. People, pets and heat-sensitive items leave for the day. Most households return in the evening after the rooms cool.
