Why heat treatment beats sprays in DH4
Heat is the only treatment that kills bed bugs at every life stage in a single pass. Adult bugs die above 113 °F; the eggs are tougher and need sustained exposure above 118 °F. We deliberately overshoot to +141 °F so the lethal threshold is hit in cracks, mattress seams, behind skirting boards and inside electrical sockets — places sprays never reach.
Bed bugs in DH4: the local picture
Bed bug cases across Durham have climbed every year since 2020. DH4 reflects the same pattern as the rest of the DH postcodes: dense housing stock, commuter movement and constant Airbnb/short-let churn give bugs a perfect introduction route.
How a DH4 treatment runs
Our DH4 treatments run in three phases: (1) ramp-up to lethal temperature (~90 minutes), (2) sustained kill phase at +141 °F (3-6 hours), (3) controlled cool-down. You'll get a written 6-month guarantee handed over before we leave site. No chemicals, no follow-up sprays, no second visit.

DH4 bed bug FAQs
How do I know if I actually have bed bugs in my DH4 property?
Tell-tale signs: clusters of small bites in lines on exposed skin, tiny dark blood-spot smears on bedding, pale shed skins along mattress seams, and a faint sweet-musty odour in heavy infestations. We can confirm on inspection.
Do you cover all of the DH postcode area?
Yes — every district from DH1 upwards. Whether you're in DH4 or a neighbouring district, the same-day heat treatment service applies.
Do I have to leave the property during treatment?
Yes, for safety reasons. Treatments typically run 4-8 hours and the property reaches +141 °F. You can return the same evening once cool-down completes.
How soon after a DH4 treatment can I sleep in the bed?
The same night. Heat treatment leaves no residue and the bed is back in use immediately after cool-down.
