Bedbug Heat Treatment Harrow

A House That Has Grown in Stages

The original part of a semi of this age tends to be a simple shape: two decent bedrooms, a small third one over the front door, a landing joining them. Extensions change that. A loft bedroom has its own staircase and sloping ceilings with eaves cupboards behind them. A rear extension may have a bedroom reached through another room. A garage conversion can put a bed on the ground floor, well away from the rest.

Each of those is a separate space as far as the equipment is concerned. When you ring, we will ask you to walk us through the house from the front door upwards, so the quote covers every room where someone sleeps or where bedding is kept, not only the ones built in the 1930s.

How the machines raise a room to a temperature bedbugs cannot survive, and how the thermal camera checks for cold spots, is on the London heat treatment page for the full explanation. This page stays with the layout of your house.

Why the Newer Rooms Matter as Much as the Old

People often assume the bedbugs are where the bites happened and nowhere else. In a house where a teenager moved up into the loft, or a grandparent sleeps in the extension, the same bedding, laundry baskets and bags travel between those rooms every day. Treating the first-floor bedrooms and leaving the loft is how a household ends up paying twice.

One heat visit that includes every sleeping room is usually the better use of money than a partial job now and a second call later. If only one room shows signs and it was caught early, we will say so, and the chemical treatment page for Harrow may suit you better.

Eaves Cupboards, Box Rooms and Other Awkward Corners

Extensions add places that the original house never had, and those are the spots we plan around:

• Eaves storage in a loft room. Low cupboards running behind the knee walls are often packed with suitcases and boxes. Clear enough of the front that the technician can open them and let warm air in.
• A box room used as a store. If it holds spare bedding, a folded sofa bed or bags of outgrown clothes, it is part of the job, even if nobody sleeps there.
• A bedroom off another room. Where the only way into an extension bedroom is through a lounge or a study, that room needs to be clear enough to pass through with equipment.
• A garage conversion. These can sit next to an unconverted part of the garage. Tell us what is on the other side of the wall.

If the extension is a conservatory or a glazed room that someone sleeps in, it behaves differently again; the Harrow Weald page deals with that case.

Getting Ready When There Are More Rooms Than Usual

The list of things that must come out before heat is the same in any house: aerosols, candles, medication, vinyl, some electronics and plants. What changes in a bigger, extended house is the sheer number of drawers and shelves to go through. Give yourself two evenings rather than one.

1. Work top down. Start in the loft room, then the first floor, then any ground-floor bedroom, so bags of removed items are not carried back up through rooms you have already finished.
2. Keep one box per room for the heat-sensitive things and label it. It makes putting the house back together much quicker once the rooms have cooled.
3. Strip every bed in every sleeping room, including a sofa bed or a guest bed that has not been used for a while, and bag the bedding for a hot wash.
4. Leave wardrobes, drawers, clothes and mattresses where they are. Those stay in to be heated.
5. Arrange for pets to be out of the house for the day, and tell us about any animals kept upstairs.

If building work is still going on, with a loft half converted or an extension without its finishes, the plan is different. The Kenton page covers treatment with builders in.

The Day Itself in a Larger House

Heat takes most of a day in any home, and a house with five or six rooms to cover can use the whole of it. We may bring more than one machine and move through the rooms in an order that suits the layout. Nobody should be in the treated rooms while the work goes on; most households find it easier to go out.

When we ring to say the rooms are cooling, you can come home, put things back and sleep in your own beds that night. Where a loft room or extension shares a wall or a roof void with next door, we may put a light residual at the edges and tell you where and when it can be touched.

What It Costs for an Extended Semi

Treatments start from £220. Heat costs more than chemical, and an extended house with extra bedrooms costs more than a two-bedroom flat. Ring 0800 955 1018, count the rooms for us including the loft and any extension, and you will have the figure on the phone before anything is booked. If you are not sure the marks are bedbugs at all, the Harrow inspection page explains that first step. For the wider picture of a changing family house, see the Harrow bedbug control page.
