Heat treatment wipes out bed bugs in a single day. Commercial heaters and fans push room temperature up while sensors confirm the heat is reaching deep into mattresses, cushions and wall edges. Most National City homes and apartments can be back in use that same evening.
Why Heat Works So Well
Held at a high enough temperature for long enough, bed bugs and their eggs simply cannot survive, and unlike sprays, heat is not something they can build resistance to. Crews generally keep the coolest spot in a room at about 120°F or higher for a set stretch of time, flipping mattresses and shifting cushions so every surface gets covered.
Treatment Day
- Getting readyHeat-sensitive belongings are pulled out. The crew sets up heaters, fans and sensors.
- Building heatRooms climb to target temperature over a few hours.
- Holding steadyTemperature is watched and items are shifted so heat reaches every corner.
- Cooldown and reviewThe room cools down, results are checked, and edges may get a residual product.
Heat Treatment in National City
A large share of National City homes date to the 1940s or 1960s building waves, so crews check the electrical panel before setting up commercial heaters in older wiring near downtown and Old Town. Heat is also a frequent choice in mobile homes, since the smaller footprint can often reach target temperature faster than a full-size house.
What Comes Out of the Room First
- Candles, crayons, cosmetics, aerosol cans, medicine, vinyl records, houseplants and pets.
- Anything the crew specifically flags, such as certain electronics.
- Items likely to soften, melt or warp under heat.
- Clothes and bedding can generally stay in place unless the crew says otherwise.
Heat Treatment Questions From National City Residents
Does heat treatment leave a smell behind?
Usually not. Heat by itself does not carry a chemical odor, though if the crew applies a residual product along the edges afterward, they will walk you through what to expect.
Could I get the same effect with my thermostat or a space heater?
No. Ordinary home heating cannot hold a room evenly at the temperature bed bugs need, and space heaters run a real fire risk when used that way.
