Does Bed Bug Heat Treatment Work?
Bed bug heat treatment is widely recognised as one of the most effective methods for eliminating bed bugs when delivered professionally. Unlike sprays or fogging, heat targets all life stages at once, including eggs.
This page explains how effective bed bug heat treatment is, why professional standards matter, and how our guarantee applies.
For an overview of the service itself, see our bed bug heat treatment page.
How Effective Is Bed Bug Heat Treatment?
When delivered correctly, professional bed bug heat treatment has an extremely high success rate. Heat works by raising temperatures throughout the treated space to levels that bed bugs and their eggs cannot survive.
Unlike chemical treatments, heat is not affected by insecticide resistance and does not rely on bed bugs moving through treated surfaces.
Laboratory and field evidence shows that sustained exposure above lethal temperature thresholds results in complete mortality of bed bugs and eggs. In practical terms, this means a 100% kill rate within the treated area when temperatures are achieved and maintained correctly.
This outcome depends entirely on professional equipment, correct preparation, and continuous monitoring.
Professional Standards and Best Practice
Our 60-Day Bed Bug Treatment Guarantee
We provide a 60-day guarantee on professional bed bug heat treatment, provided that preparation guidelines have been followed and the infestation relates to the originally treated areas.
The guarantee exists to give customers confidence and reassurance while recognising that reintroduction can occur in high-mobility environments.
During the guarantee period, any suspected bed bug activity linked to the original infestation will be assessed. Where appropriate, further action will be taken in line with the guarantee terms.
What the Guarantee Covers
The guarantee covers bed bug activity arising from the original infestation within the treated areas. It does not cover new infestations introduced after treatment, such as those brought in via travel, visitors, or second-hand furniture.
Full terms, conditions, and eligibility requirements for the guarantee are set out in our terms and conditions.
Real-World Results and Expectations
The majority of professionally delivered heat treatments resolve infestations in a single visit. Post-treatment monitoring helps confirm success and provides early reassurance.
Where concerns arise, assessment focuses on whether activity is consistent with the original infestation or a new introduction.
What to expect during monitoring is explained on our Aftercare & Follow-Up page.

FAQs
Is heat treatment guaranteed to work?
When delivered professionally and preparation guidance is followed, heat treatment is one of the most reliable methods available.
Why do some treatments fail elsewhere?
Failures typically result from inadequate equipment, insufficient temperature control, or poor preparation rather than limitations of heat itself.
Does the guarantee cover re-infestation?
No. Re-infestation caused by new introductions is not covered, which is why prevention guidance is important.
Summary
Professional bed bug heat treatment is highly effective when delivered correctly. A 60-day guarantee applies when preparation guidance is followed, with full terms set out separately.
