Bedbug Heat Treatment Waltham Forest

Why We Treat the Floor, Not the Room

Upstairs in a Victorian or Edwardian terrace, the bedrooms open off one small landing, often only a stride or two apart. The same carpet runs along the landing and under each door. Children move between beds in the night, a partner goes to the box room when someone is snoring, and the laundry basket travels from room to room. Each of those is a lift for a bedbug.

So when you ring, we ask about the whole floor, not just the room where the bites started. If two rooms are affected and the other two share a landing with them, heating all of them in one visit costs more on the day but avoids the next call in a month. If only one room has anything and nobody has slept anywhere else, one room may be enough, and we will say so.

How the heat itself kills bedbugs and their eggs is set out on the London heat treatment page for the full explanation. This page is about how it fits a terraced house in this borough.

The Rooms People Forget to Mention

A quote is only as good as the list of sleeping places. In these houses the easy ones to leave out are:

• The box room over the front door, used as a study but with a sofa bed in it
• The back addition bedroom over the kitchen, reached down a couple of steps
• A loft room, if the house has one, which counts as part of the upstairs
• The landing itself, where a chest of drawers or airing cupboard sits next to a bedroom door
• The front room downstairs, if anyone has been sleeping on the sofa since the bites began

Tell us about all of them, even the ones that feel temporary. The room left out of the plan is the one the survivors come back from.

Sash Windows, Old Floorboards and Fitted Cupboards

Older houses have more gaps than new ones: boards that have shrunk apart, skirting that has come away from the plaster, and cupboards built into the alcoves beside the chimney breast. Bedbugs use all of these. Heat gets into them in a way a spray struggles to, because the warmth soaks through the timber rather than relying on a product reaching the back of a crack.

The thermal camera matters more in these rooms, not less. A built-in wardrobe against an outside wall or a thick old skirting can lag behind the rest of the room, and that is where we look before we call it done. If the bed sits under a window, the frame and any blind above it are worth checking too; our guide on bedbugs in blinds and window frames covers what to look for there.

Getting the House Ready

With a whole floor to heat, the day goes better if the preparation is shared out. A few points that apply to a family house in particular:

1. Clear the landing first. It is the route in and out for us and for the equipment, so baskets, shoes and toys come off it the day before.
2. Pack the heat-sensitive list room by room. Aerosols, candles, medication and so on go into one box per room, and the boxes go downstairs, not into the next bedroom.
3. Leave beds made up or stripped as we advise when we book. Do not carry bedding down through the house unbagged.
4. Plan the day away. Everyone is out of the heated rooms, pets included, until the rooms have cooled. Most families go out for the day.

If you would prefer not to use heat, or the cost of a whole floor is too much, the chemical treatment page for Waltham Forest explains how that course works in a rented flat. Anyone weighing the two because of worries about products in the home may find the Walthamstow Village page useful.

The House Next Door

A terrace shares a wall on one or both sides, and upstairs that wall often has a bedroom against it. Heat leaves nothing behind once the rooms cool, so where we think bedbugs may be coming through from next door, we may put a light residual along the skirting of the shared wall after the heat. That gives anything arriving later something to cross.

If you think the neighbours have them too, a word with them helps more than anything we can do from your side of the wall. The Waltham Forest bedbug control page covers raising it with neighbours, housemates and landlords.
