A family in central St Albans had been battling bed bugs for nearly six months after a holiday abroad. Two failed chemical treatments had pushed the infestation deeper into bed frames and skirting boards. We carried out a single-day whole-room heat treatment across all three bedrooms.
Before treatment
- Live bed bugs visible on mattress seams and headboards in two of three bedrooms
- Heavy faecal spotting along skirting boards and behind a Victorian cast-iron fireplace
- Bites on all three family members, worsening each night
- Two previous chemical sprays had reduced numbers temporarily but not eliminated eggs
After treatment
- Zero live bed bugs detected on the 14-day inspection follow-up
- All bites cleared within 10 days of treatment
- Family sleeping in original bedrooms the same evening, no replacement furniture required
- Treatment guarantee held — no callbacks needed
How we carried out the treatment
- 1
On-site survey
Identified primary harbourage in bed frames, skirting, and behind a fitted wardrobe. Confirmed Cimex lectularius across all upper-floor rooms.
- 2
Preparation
Family removed heat-sensitive items, washed bedding on 60°C and removed pets and houseplants for the day.
- 3
Heat treatment
Three industrial heaters and circulation fans raised every room to a sustained 56°C, monitored with remote probes inside mattresses and wall voids.

Aftercare
Provided a prevention pack, mattress encasements, and booked a free 14-day inspection.
"We had tried two other companies before. After one day with Hertfordshire Pest Experts the bed bugs were gone and they haven't come back. Worth every penny."
Frequently asked questions
- How quickly can you treat a Victorian terrace in St Albans?
- We usually have availability within three to five days. For this St Albans AL1 property we carried out the full survey and treatment within a week of the first call.
- Is heat treatment safe for old skirting boards and fireplaces?
- Yes. We use remote temperature probes to stay within safe limits. The original Victorian skirting and cast-iron fireplace in this home were completely unaffected.
- Do I need to throw away mattresses after a severe infestation?
- Not usually. Heat treatment sanitises mattresses, bed frames and soft furnishings so they can be kept. This family kept all three beds and only replaced one damaged headboard.
- Will heat treatment work if chemicals have already failed?
- Absolutely. In fact this case is typical: two previous chemical sprays had driven the bugs deeper. Heat penetrates harbourage that sprays cannot reach and kills eggs as well as adults.
