Bed Bug Heat Treatment in North West Wales
North West Wales covers Ynys Môn and Gwynedd: the Menai Strait, the Llŷn peninsula, Eryri and the Meirionnydd coast. Bangor and Caernarfon carry the everyday population, while the peninsula, the mountain passes and the Cardigan Bay coast are long single journeys. Hubs here are set by real driving time on the A55, A487 and A470, not by distance on a map.

Areas we cover
North West Wales districts, service areas and postcodes
Coverage grouped by authorities, with service areas, postcode districts and boundary detail from the verified geographic registry. A geographic match is not the same as confirmed service availability.
Ynys Môn (Isle of Anglesey) and Gwynedd are two separate unitary authorities. They are covered together as one service area because the road network runs through Bangor, but they are not one council, and each table states the authority an address sits in.

Property and access
What affects a North West Wales heat treatment
The practical detail of the building changes the plan far more than the region does.
University and student housing
Bangor holds a large shared student market in converted terraces and multi-occupancy houses, where a reported room is treated as part of a whole building rather than in isolation.
Holiday cottages and caravan accommodation
Abersoch, Criccieth, Barmouth, Benllech and the Anglesey coast carry self-catering property with weekly changeover, so work is planned around the booking calendar.
Slate-built terraces
Blaenau Ffestiniog, Bethesda, Llanberis and the quarrying villages hold dense stone and slate terraces with deep skirtings and timber floors that affect how heat is held.
Port and ferry town property
Holyhead has transient accommodation linked to the Irish crossing, including guest houses and shared housing that are assessed as whole units.
Remote farm and upland property
Llŷn, Meirionnydd and the Eryri valleys sit on single-track roads where access, parking, turning space and available power are confirmed before a date is agreed.
Coastal retirement housing
Llanfairfechan, Beaumaris, Tywyn and Aberdyfi hold older detached and bungalow stock where the survey covers the full property rather than one reported room.

Guarantee
Six-month guarantee
6-Month Guarantee
Our six-month guarantee provides additional reassurance following qualifying treatments. Full guarantee conditions are provided before treatment and form part of the customer agreement.
Terms and conditions apply. The guarantee is conditional, and known operational conditions include matters such as:
- Bed bug activity originating from an adjoining property
- Reintroduction following treatment
- Activity outside the agreed treatment scope
- Failure to comply with agreed preparation requirements
- Failure to follow relevant aftercare requirements
Full conditions are provided in writing before treatment. This page explains the principle of the guarantee only — it is not the customer agreement.

Questions
North West Wales questions
- Is Anglesey covered separately from Gwynedd?
- They are two separate councils and each address is labelled with its own authority, but both are worked as one service area because the roads run through Bangor.
- Do you cover the Llŷn peninsula?
- Yes. Pwllheli is a hub in its own right and covers Nefyn, Abersoch, Aberdaron and the surrounding villages.
- Can Welsh place names be used when booking?
- Yes. Welsh and English forms of the same place are recorded against one entry, so either spelling finds the right location.
- How are holiday lets handled?
- Work is planned around changeover so properties return to service in an agreed order, and the whole unit is assessed rather than a single room.
- Are mountain and coastal villages reachable?
- Yes, with travel time built into the day. Appointments in Eryri, Llŷn and Meirionnydd are grouped by hub rather than booked singly.
