Bed Bug Treatment Aftercare & Guarantee
Aftercare plays a critical role in ensuring long-term success following bed bug heat treatment. While professional heat treatment is designed to eliminate bed bugs and their eggs in a single visit, understanding what to expect after treatment helps avoid unnecessary concern and reduces the risk of reintroduction.
This page provides detailed guidance on post-treatment behaviour, monitoring, prevention, and how our guarantee applies.
For an overview of our service, visit the Bed Bug Treatment London page.
Immediately After Treatment
Once treatment is complete and the property has cooled to a safe temperature, you can re-enter the treated areas. In most London properties, this is the same day. Windows may be opened for ventilation, but no special cleaning products or treatments are required.
Is Post-Treatment Activity Normal?
It is normal to see dead bed bugs after treatment. In rare cases, you may also notice a small number of sluggish insects shortly after treatment. This does not indicate failure. Heat treatment kills all life stages, including eggs, and residual movement can occur as insects succumb.
A detailed explanation of bed bug behaviour after treatment is available on our bed bug aftercare guide.
Cleaning, Laundry and Daily Living
Normal daily activities can usually resume immediately. Washed and sealed clothing and bedding may be returned to drawers and wardrobes. Avoid unnecessary deep cleaning, rearranging furniture, or moving items between rooms during the initial monitoring period unless advised.
The Monitoring Period Explained
A monitoring period allows confirmation that the infestation has been fully resolved. Monitoring is particularly important in flats, HMOs, and shared buildings where reintroduction risks can be higher.
Ongoing prevention and early detection steps are covered on our Prevention & Monitoring page.
Understanding the Guarantee
ThermoPest provides a clear guarantee when professional preparation guidance has been followed. If bed bug activity linked to the original infestation is identified within the stated guarantee period, we will assess the situation and respond accordingly.
Preparation responsibilities are outlined in the Bed Bug Treatment Preparation Guide.
What the Guarantee Does and Does Not Cover
The guarantee applies to bed bug activity arising from the treated infestation. It does not cover new introductions caused by travel, visitors, or second-hand furniture. This distinction is important in high-mobility London environments.
When to Contact Us After Treatment
You should contact us if you observe persistent activity beyond the normal monitoring period, or if you have questions about post-treatment behaviour. Photographic evidence may be requested to help determine whether activity is related to the original infestation or a new introduction.

FAQs
Will bites stop immediately?
Bites usually stop quickly, but skin reactions may continue for days or weeks after bed bugs are eliminated.
Can I move furniture or redecorate?
Yes, once treatment is complete and the property has cooled. Avoid major changes during the monitoring period where possible.
Is repeat treatment common?
No. Professional heat treatment typically resolves infestations in a single visit when preparation steps are followed.
Summary
Aftercare following bed bug heat treatment involves normal use of the property, a short monitoring period, and prevention steps to avoid reintroduction. Guarantees apply where preparation guidance has been followed.
