A shared house near the University of Hertfordshire had bed bugs moving between bedrooms through shared wall cavities. Chemical sprays from a budget provider had only driven the problem deeper. We treated all four bedrooms, the communal bathroom voids and the downstairs lounge in one intensive day.
Before treatment
- Live bugs and eggs in all four upstairs bedrooms, including inside desks and wardrobes
- Heavy spotting along shared wall skirting where bugs were migrating room-to-room
- Three of four housemates reporting nightly bites for over a month
- Previous chemical treatment had reduced surface numbers but missed eggs in voids
After treatment
- All four bedrooms and communal areas cleared in a single visit
- 30-day inspection confirmed zero live activity in every room
- Housemates able to remain in the property with no furniture replacement
- Landlord received a written guarantee for tenancy compliance

Aftercare
Sealed mattress encasements fitted to all beds. Issued landlord treatment certificate and scheduled a 30-day re-inspection.
"We were losing sleep and getting stressed about our deposit. One day of heat treatment sorted it for the whole house. The landlord was really impressed with the paperwork too."
Frequently asked questions
- How do bed bugs spread between rooms in a Hatfield student house?
- In this AL10 property the bugs used shared wall cavities and pipe runs to migrate between bedrooms. Chemical sprays only treated surfaces, so the migration routes stayed active. Heat penetrates these voids and stops movement at the source.
- Do all housemates need to leave during treatment?
- Yes, everyone must vacate for the day. The students relocated to the university library and a friend's house for the eight-hour treatment and returned that evening.
- Can landlords use your paperwork for deposit disputes?
- Yes. We issue a formal treatment certificate and guarantee that can be attached to tenancy records or used in deposit-protection correspondence.
- Is one day enough for a four-bedroom shared house?
- Yes. This severe infestation was cleared in a single intensive day. We used four heater units and extended monitoring in wall cavities to make sure nothing survived.
