Bed Bug Treatment across Stevenage and SG1
The SG1 postcode covers Stevenage and the nearby communities of Old Stevenage, Shephall, Pin Green, Knebworth. Property type matters more than which street the infestation appears on: Victorian terraces and conversion flats tend to spread bugs through shared cavity walls, whereas modern apartment blocks usually contain an infestation to a single unit if treated promptly.
Why heat treatment outperforms insecticides in Stevenage
Bed bug eggs are armoured. They survive most over-the-counter sprays and a large proportion of professional pesticide treatments — which is why chemical jobs almost always require 2-4 follow-up visits across 6-8 weeks. Heat is different. Sustained temperature above 118 °F denatures the proteins inside the egg shell; nothing alive comes out of it. One thermal cycle, one finish.
What our bed bug treatment service covers
Whether you've already tried sprays and the bugs came back, or this is your first infestation, a single heat treatment ends it. We treat every property type — flats, houses, HMOs, hotels, hostels, Airbnbs, council stock — and provide everything in writing.
The treatment process for a SG1 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 Stevenage 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 Stevenage 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
Every treatment ships with a written 6-month guarantee handed over before we leave site. If live bed bugs reappear at the treated address within the guarantee period and you can supply video evidence, we return to re-treat the property free of charge. The guarantee covers the full address, not just the rooms originally treated, provided the infestation is the same species and not a fresh introduction from outside.
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

Stevenage bed bug treatment FAQs
How long does a typical bed bug treatment take?
A one or two-bed property is usually treated in a single working day (6-9 hours on site including ramp, kill phase and cool-down). Larger properties may need two crew rotations but still complete in one visit.
Will the treatment work if my Stevenage property is in a shared building?
Yes, but we'll inspect the boundary walls and floor voids during the survey. Where bugs have migrated to adjacent units we'll recommend the neighbouring property is treated at the same time to prevent reintroduction.
Will the treatment damage my belongings in Stevenage?
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 Stevenage 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 Stevenage 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.
