Where Bedbugs Settle in Fitted Furniture
A fitted wardrobe or a raised platform bed is a box of joints. Every place where a panel meets another panel, a wall or the floor is a narrow gap, and those gaps are exactly what bedbugs look for. The spots to check:
- The plinth at the bottom of a fitted wardrobe, where it meets the carpet
- Screw holes, shelf pins and hinge plates inside the doors
- The underside of a platform bed and the ladder or steps up to it
- Storage drawers built into a bed base, especially their runners
- The strip where the furniture meets the wall or the ceiling
Use a torch and a thin card along each join. Dark spotting, like a felt pen dot that smears, is the thing most people find first.

Why You Should Not Try to Take It Apart
It is tempting to unscrew the whole unit to get at them. Please do not. Taking fitted furniture apart shakes bedbugs out of the joints and onto the floor, and panels carried through a flat to a hallway or a skip spread them on the way. In a rented room it can also cause damage you are asked to pay for.
Leave it assembled and let us treat it as it is. If a unit really does need removing afterwards, that can be planned once it has been treated.
What Each Treatment Does With Joinery
With chemical treatment, we work a residual insecticide into the joints, plinths, hinge points and the bed frame. It keeps working as bedbugs come out over the following days, but it does not reliably kill eggs, so the course is usually two visits and sometimes three, spaced about 10–14 days apart. The wardrobe floor and the shelves need emptying for each visit.
With heat treatment, the whole room is raised to a temperature bedbugs cannot survive and held there, so heat soaks into the panels and the gaps behind them, eggs included. The thermal camera is pointed at the back corners of the wardrobe and the underside of the bed until they have caught up. It is usually one visit and costs more than chemical.
Getting a Built-In Room Ready
For either route, the wardrobe contents go into bags, and washable things go through a hot wash and dryer before being sealed. For heat, aerosols, candles, medicines, plants and some electronics come out of the room; the full list comes with your booking. The doors of every fitted unit and every drawer should be left open on the day.
A full wardrobe in a small Clapham room can feel like a mountain to sort. Our guide on whether clutter makes bedbugs worse covers what really has to move and what can stay. If you rent and the furniture belongs to the landlord, tell them in writing; the Lambeth page has more on renting with bedbugs.
Bedbug Control Clapham — Questions
Can bedbugs get behind a fitted wardrobe into the wall?
They can shelter in the gap at the back and along the edges where it meets the wall. Heat reaches that gap well; chemical is applied along the edges and joints.
Do I need to empty the wardrobe for heat treatment?
Not always. Clothes can often stay if the doors are open, but anything on the heat-sensitive list must come out. We go through it with you when you book.
Can a cabin bed with drawers underneath be treated?
Yes. Pull the drawers out and empty them, leave the bed where it is, and we treat the frame, runners and drawer spaces.
Is heat or chemical better for a Clapham room full of built-ins?
Heat is often the easier fit, because it gets into joints a spray cannot. Chemical still works if the course is followed through; we will say which we would use once we know the room.
How much does it cost?
Prices start from £220, and heat costs more than chemical. The exact price is given on the phone before any booking.
