24 Hour Bed Bug Treatment across Wandsworth and SW18
Wandsworth (SW18) sits inside the SW postcode area in Greater London. The local housing mix — modern apartment blocks and Victorian terraces around the riverside developments — is exactly the kind of environment bed bugs thrive in once they have been introduced via luggage, second-hand furniture or a previous tenant's belongings. Surrounding villages including Earlsfield, Southfields, Tooting Bec fall inside the same response radius and share the same call-out profile through the year.
Why heat treatment outperforms insecticides in Wandsworth
Pyrethroid resistance in UK bed bug populations has been documented for over a decade and is now widespread. That is why chemical-only treatments are increasingly ineffective. Heat is a physical kill mechanism — bed bugs cannot evolve resistance to having their proteins cooked. The science is straightforward and the result on site is predictable.
What our 24 hour bed bug treatment service covers
Same-day response is our default for confirmed infestations. Out-of-hours calls (evenings, weekends, bank holidays) are taken live; the technician dispatch happens at the next safe operational window so the kill phase always runs in daylight.
The treatment process for a SW18 property
Heaters are positioned to drive airflow rather than just temperature. That distinction matters: a stagnant hot room leaves cold pockets where bugs survive, whereas active circulation forces lethal heat into every cavity, void and seam. Fans are repositioned twice during the kill phase based on the live probe data.
Preparing your Wandsworth home for the treatment
Heat treatment requires minimal preparation. Before the technician arrives, remove anything from the treatment zone that cannot tolerate sustained heat above 60 °C: pets, fish tanks, plants, candles, vinyl records, oil paintings, pressurised aerosols and any prescription medication. Everything else — including mattresses, sofas, books, clothing and electronics — stays in place and is sterilised in the same cycle.
Aftercare and what to expect that evening
In the days following a Wandsworth treatment you may briefly see one or two dead bugs work loose from cracks as they desiccate — this is normal and indicates the kill was effective. Live activity should be zero. If you do see any live evidence within the 6-month guarantee window, video it and call us; we re-treat free of charge.
Our written 6-month guarantee
The 6-month guarantee in writing is what separates a real heat-treatment job from a one-and-done spray. We're prepared to back the kill because the protocol — sustained +141 °F core temperature, verified by probe data — works. For Wandsworth customers we keep treatment records on file for the full guarantee period.
Preparation checklist
- Remove pets, fish tanks and houseplants from the treatment zone
- Stage candles, vinyl records, oil paintings and pressurised aerosols outside the heat area
- Leave bedding, wardrobes and soft furnishings exactly where they are
- Empty fridges only if scheduled for the treatment room itself
- Switch off and unplug temperature-sensitive electronics such as printers
- Hand the technician access to every affected room and adjacent boundaries

Wandsworth bed bug treatment FAQs
Do you actually run heat treatments at night?
No — fire safety, monitoring protocol and the duty-of-care requirement for in-room probe checks mean the kill phase always runs in daylight. The 24-hour element is the call handling and the dispatch decision, both of which happen around the clock.
What can I do tonight while I wait for the Wandsworth treatment slot?
Stay in the bed (don't move to the sofa — it migrates the bugs), place luggage on a hard floor away from soft furnishings, run any clothes you can on a hot wash + tumble dry, and don't spray over-the-counter products that scatter live bugs into the rest of the property.
Will the treatment damage my belongings in Wandsworth?
No — the lethal threshold is 118-141 °F, well below the damage point for wood, mattresses, fabrics, modern electronics and most books and artwork. Temperature-sensitive items are staged outside the heat zone before ramp-up; we provide a full list in the preparation email after booking.
Is heat treatment safe for children and pets after we re-enter the Wandsworth property?
Yes. There are no residual chemicals, no sprays and no airborne toxins. The room cools to ambient temperature within two to three hours of switch-off and is safe to occupy the same evening.
How do I know the bugs are actually dead in my Wandsworth home?
You receive the wireless-probe temperature log on completion alongside the written 6-month guarantee. Sustained core temperature above 118 °F in the worst-case void is the proof that nothing alive remains.
