How Long Bed Bug Heat Treatment Takes in London

One of the most common questions we are asked is how long bed bug treatment takes. In most London properties, professional bed bug heat treatment can be completed in a single day. The exact duration depends on the size of the property, infestation spread, and preparation.

This page explains realistic treatment times, what happens on the day, and when you can safely return to your home.

Typical Bed Bug Heat Treatment Times

Below are typical timeframes for professional bed bug heat treatment in London properties. These are realistic averages rather than minimum promises.

  • Single room or bedroom: approximately 4–6 hours
  • Studio flat or bedsit: approximately 5–7 hours
  • One-bedroom flat: approximately 6–8 hours
  • Two-bedroom flat: approximately 8–10 hours
  • Houses and HMOs: full day or staged treatment depending on layout

What Happens During the Treatment?

On the day of treatment, professional heating equipment is installed and temperatures are gradually raised to lethal levels for bed bugs and their eggs. Wireless sensors continuously monitor conditions to ensure all areas reach and maintain target temperatures.

Is More Than One Visit Required?

In most cases, a single heat treatment is sufficient when preparation guidelines are followed correctly. Unlike chemical-only methods, heat treatment kills eggs as well as live bed bugs in one visit.

How the process works is explained in detail on our How Bed Bug Heat Treatment Works page.

When Can You Return to the Property?

Most customers can safely re-enter their property on the same day, once temperatures have returned to normal levels. There is no prolonged vacancy period required, which makes heat treatment particularly suitable for busy London households and rental properties.

Does Preparation Affect Treatment Time?

Yes. Proper preparation helps the treatment run smoothly and finish on schedule. Poor preparation can increase treatment time or reduce effectiveness. Preparation steps are outlined in our Bed Bug Treatment Preparation Guide.

How Treatment Time Relates to Cost

Treatment duration is one of the factors that influences pricing. Larger or more complex properties require longer treatment times and more equipment. Cost information is covered on our Bed Bug Treatment Cost page.
