A young family in Hemel Hempstead discovered the infestation had spread from the master bedroom into the children's rooms and the living room sofa. We carried out a whole-house heat treatment in a single visit, including soft furnishings downstairs.
Before treatment
- Live bed bugs in three bedrooms and the living-room sofa
- Eggs visible inside picture frames and behind curtain pelmets
- Children's bites causing sleep disruption for several weeks
- Previous DIY sprays had pushed bugs into wall voids
After treatment
- Whole house cleared in one visit — no return of activity at the 30-day check
- Sofa, mattresses and soft toys all retained, no replacement furniture purchased
- Children back in their own beds the same night
- Family enrolled in our annual prevention check at no extra cost

Frequently asked questions
- How long does a whole-house heat treatment take in Hemel Hempstead?
- This four-bedroom semi-detached in HP1 took nine hours from arrival to departure. Larger family homes typically need six to ten hours depending on room count and severity.
