Flats in Willesden's converted terraces change hands often, and the carpet usually stays put when the people and their animals go. Flea pupae sit in the pile and along the skirting quite happily through an empty month, waiting for warmth and footsteps.
Rooms are priced one at a time — £180 for the room you start with, then £60 a room. Book a flea treatment here, or ring 0800 955 2347.

Adult fleas live on an animal, but their eggs do not stick; they roll off wherever the cat or dog settles and develop in the floor covering underneath. That is why a flat can be spotless at the viewing and still produce a wave of bites round the ankles days after the keys change hands. Cocoons hold their adults back until vibration, warmth and carbon dioxide say someone is there, and moving in supplies all three at once. Can you have fleas without having pets? explains how a household with no animal ends up bitten.

In a converted house the flooring is often inherited: a carpet laid over the original boards by a previous owner, a landlord's neutral cord in the bedrooms, a rug left behind because it was not worth moving. Larvae work down away from the light into the pile, into the gap at the skirting and into the joints of the boards beneath — the Pest Control Willesden page describes what those old floors are like underneath. Vacuuming lifts some of them, but not the ones already below the surface, which is why a thorough clean before you move in is not the whole answer. Where fleas hide around the home covers the less obvious spots, and fleas in beds and sofas deals with the furniture.
Inside your own flat, a tenant should tell the landlord or agent in writing what the bites are, when they started and which rooms they happen in; who pays depends on the tenancy and the circumstances. The communal hallway and the stair carpet up to the flats belong to the freeholder or managing agent, so mention fleas there to them rather than trying to sort it between neighbours. If the flat next door or below also has an animal, it is worth a word, because everyone uses the same front door and hall. Do landlords need flea treatment between tenancies? sets out when treating before a re-let makes sense.

Behind these terraces the gardens run in one long chain, linked by walls, fences and the rear passage, and cats use the whole chain as a single territory. Foxes lie up under a shed, in a pile of timber down the side alley or beneath a decked corner. Fleas drop off wherever an animal rests, so a resident cat that sleeps under your shed, or a fox beneath the decking, leaves eggs and larvae right beside the back door. A cat flap that any local cat has learned to use brings the same thing indoors. It is one of the reasons a ground-floor flat with no pets of its own can still get fleas.
Preparing a property for flea treatment has the full checklist, and our Brent flea advice takes in the wider picture.
Keep vacuuming every day for a while: the vibration is useful, because it encourages the remaining fleas out of their cocoons. How long that goes on varies with the flat and how established they were, so nobody can put a date on it honestly. If bites are not easing, or live fleas keep turning up, tell us which rooms and we will take it from there. Why fleas can still bite after treatment explains what is going on.
Most of it comes back to the animals, yours and the neighbourhood's. Flea Control Brent covers the rest of the borough, and nearby Kilburn has the same kind of shared houses.
A Willesden flea job starts at £180 for one room, with every further room £60. Bedrooms and living rooms with carpet, rugs or upholstered furniture are counted; the communal hallway, the stairs up to the flat and your own landing are not, so two bedrooms and a living room come to £300. The price covers treating the rooms you book, and we go through what happens on the day before you confirm.
| Treatment | Price |
|---|---|
| Fleas – First Room | £180 |
| Fleas – Additional Room | £60 |
Note which rooms the bites happen in and when they started, vacuum those rooms daily, and look for tiny dark insects jumping onto socks or specks of flea dirt at the carpet edge. Then book flea treatment for the affected rooms. Flea problems after moving into a new home goes through it.
A previous occupant's cat or dog is the usual answer, and the young stages can wait in the carpet long after the animal has gone. A visiting cat through a flap or an open back door can do it too, as can a fox resting under a shed just outside.
The vet's product deals with the fleas on the cat; the eggs, larvae and cocoons already in the carpets carry on regardless. Both sides need doing at once — see whether pet flea treatments clear the house.
Communal areas are normally the freeholder's or managing agent's responsibility, so report it to them in writing. Inside your own flat, it is you or your landlord, depending on the tenancy. Hallways and stairs are not counted as rooms in the price either way.
The bedroom and the living room are rooms; the hall, the landing and the stairs are not. So a bedroom and a living room together come to £240, and each further room after that is £60.
They can. Flea bites cluster round the ankles and lower legs, while bites on the arms, neck or shoulders that appear after a night in bed point to bed bugs, and itchy skin along with small hairy larvae at the carpet edge suggests carpet beetles. A pharmacist or GP can advise on any bite that looks infected. How to know if you have fleas helps you check.
That depends on the flat and how long the fleas have been there, since cocoons hatch over a period rather than all at once. How long flea treatment takes to work explains what affects it; keep vacuuming and tell us if bites are not settling.
