Why heatSprays manage infestations.
Sprays manage infestations.
Heat ends them.
UK bed bug populations are increasingly resistant to residual insecticides. Heat is a physical kill — nothing to become immune to.
One treatment. Every life stage.
Heat kills adults, larvae, nymphs and eggs simultaneously — no follow-up sprays, no re-treatment cycle.
Zero chemicals, zero residue
Safe around children, pets and sensitive occupants. No airing out, no washing everything down.
Back in your home the same day
Most properties are treated, cooled and cleared inside 8 hours. No hotel bill, no weeks of laundry.
Guaranteed in writing
Backed by a 6-month guarantee and verified with thermal imaging cameras on every job.

The treatment
Our Professional Heat Treatment Process
Specialist industrial heat equipment designed to raise and maintain temperatures throughout every affected area — furniture, cracks, crevices, bed frames, skirting boards and all harbourage points.
01
Initial Assessment
We inspect beds, mattresses, sofas, skirting boards, sockets and wardrobes, then discuss infestation history and any rooms needing special attention.
02
Preparation — Day Before Assessment
This must be completed the day before our initial assessment. Remove aerosols, candles, medication, batteries, electronics, plants and delicate plastics. Clothing, bedding and furniture stay in place to be heated properly.
03
Setting Up the Equipment
Industrial heaters, air movers, ducting and thermal monitoring are positioned carefully to circulate hot air into every void and harbourage point.
04
Controlled Temperature Increase
Temperature rises gradually so heat penetrates deep into furniture, mattresses, gaps and structural voids where bed bugs live and breed.
05
Continuous Monitoring
Thermal imaging cameras monitor every area in real time, detecting cold spots and confirming lethal heat levels are reached and maintained throughout the property.
06
Heat Soak Period
The property is held at treatment temperature for a set period. Adults, nymphs and eggs must be exposed to lethal heat long enough to be fully controlled.
07
Moving and Rotating Items
Technicians move and rotate furniture, mattresses and cushions to eliminate cold spots and ensure complete heat coverage on all sides.
08
Final Inspection
Key harbourage points are checked again after treatment. Findings are recorded and post-treatment guidance is provided before we leave.
09
Aftercare Advice
A small number of dying bugs may appear briefly. Bites can continue for 2–3 weeks due to delayed skin reactions. Do not move items between rooms.
10
Guarantee and Follow-Up Support
Live video evidence is required for any follow-up claim. Our team reviews the footage, advises on next steps and arranges further treatment under guarantee terms.
