Find the source, clear the reservoir, then treat. In a top-floor flat the source is usually above the ceiling; in a ground-floor one it usually came in with something.
Find the source and remove it, vacuum the reservoir hard and weekly, then apply a residual treatment.
In a flat the source depends on the floor. Top floor points to the roof void; lower floors point to something brought in — a second-hand rug, stored textiles, or old debris under a floor.
| Where you are | Look at |
|---|---|
| Top-floor flat | The roof void — nest, feathers, carcass, debris |
| Any floor | Stored textiles in a cupboard |
| Any floor | A second-hand rug, sofa or armchair |
| Any floor | Light fittings and window voids full of dead insects |
| Ground floor | Debris under a suspended floor, if there is one |
| Any floor | Old wool items inherited or brought from a previous address |
| Converted flat | A shared roof void, if you are directly beneath it |
In a purpose-built block the source is nearly always something that came through the front door. In a converted house it is nearly always above the ceiling.
£180 for the first room, £60 for each additional. Published, up to four rooms.

|---|---|
| Treating the room, leaving the source | Buys a year. The classic mistake |
| Moth balls in a room | Only work inside a sealed container |
| Supermarket spray on visible beetles | Kills adults, ignores larvae in the pile |
| Foggers | Do not reach carpet base or board gaps |
| Pheromone traps | Less reliable for beetles than for moths |
| Cedar and lavender | Pleasant. Not a control |
| Steam cleaning after treatment | Removes the residual |
Not directly. The larval hairs can irritate skin in some people, which is occasionally mistaken for bites.
Some related species will get into dry pet food and birdseed. Check those cupboards too.
Not while there is a source and wool to eat.
While someone is in the loft — a wasp nest up there is £90 fixed in Rayners Lane, guaranteed for 30 days.
Find the source and remove it, vacuum the reservoir hard and weekly, then apply a residual treatment with a follow-up.
Top floor points to the roof void — a nest, feathers or a carcass. Lower floors point to something brought in, such as a second-hand rug or stored textiles.
Treating the room and leaving the source. That buys you a year rather than solving it.
An accessible disused nest, yes. Active nests of wild birds are protected during the breeding season and must be left.
Moth balls only inside a sealed container. Cedar and lavender are pleasant but are not a control.
Wash at 60°C where possible, freeze the rest for 72 hours in a sealed bag, and store clean and sealed rather than loose.
Judge it over a season. The larval stage lasts months, and a small spring emergence can follow even a successful treatment.
Some related species get into dry pet food and birdseed, so check those cupboards too.
Top floor? Check the roof void first. Lower down? Check what came in with you.
