Only about one flea in twenty is on your pet. The rest are in the carpet, and that is why the carpet is where this is won or lost.
Treat the pets, vacuum obsessively, wash the bedding hot, and have the carpets professionally treated. Treatment is £180 for the first room and £60 per additional room.
The thing to understand: the adults you can see are a small fraction of the population. The eggs, larvae and pupae are down in the carpet pile, and that is what actually needs dealing with.
The visible fleas are the smallest part of the picture. The bulk of a flea population is in the carpet, at stages you cannot see:
| Stage | Where it is | Roughly what share |
|---|---|---|
| Adults | On the animal | A small minority |
| Eggs | Fallen into carpet and bedding | A large share |
| Larvae | Down in the carpet pile | A large share |
| Pupae | In cocoons in the carpet | The stubborn remainder |
So killing the adults on your pet, while necessary, addresses the smallest part of the problem. The carpet is where the rest of it lives.
Nothing else works without this. Speak to your vet rather than buying a supermarket spot-on, because effectiveness varies considerably and using the wrong product is a common reason people believe treatment has failed.
Treat every animal in the household, not just the one that is obviously scratching.
We do not sell pet treatments and have no interest in which you use. We are telling you because a house treated without the pets treated is money spent on a problem that walks straight back in.
Vacuuming does three genuinely useful things with fleas, and it is the most effective thing a householder can do:
How to do it properly:
Heat is what kills fleas at every stage. A hot wash followed by a hot tumble-dry is the domestic tool that genuinely works.

That last part matters. A one-off knockdown does nothing about the pupae that hatch next Tuesday — which is exactly why supermarket sprays disappoint.
This alarms people, and it is usually the treatment working rather than failing.
Pupae are protected inside a cocoon and can remain dormant for a long time, hatching only when they detect vibration, warmth and carbon dioxide — a person or an animal walking past. No treatment kills a dormant pupa efficiently, so the process is necessarily one of waiting for them to emerge and meeting them when they do.
Which is why the advice after treatment is counterintuitive: keep walking on the carpets and keep vacuuming. You are encouraging them out.
Common, and usually explicable: a previous occupant's animal, a neighbour's cat using the garden, or wildlife in a loft space. If you have no pet and no obvious explanation, mention it — occasionally it points at squirrels or birds in a roof, which is a separate problem underneath this one.

Treat the pets via a vet, vacuum thoroughly every day, wash bedding hot, and have the carpets professionally treated.
Only the adults live on the animal. The eggs, larvae and pupae — the bulk of the population — are down in the carpet pile.
Considerably. It removes eggs and larvae, removes the debris larvae feed on, and the vibration triggers pupae to hatch where treatment can reach them.
They kill adults on contact but rarely persist long enough to deal with pupae hatching over the following weeks.
Poorly. They settle on the carpet surface rather than penetrating the pile where the larvae are.
No. Fleas are also in the underlay, floor gaps, skirtings and furniture, so it is a large expense for little benefit.
Pupae hatch over a period and no treatment kills a dormant pupa efficiently. Keep vacuuming and walking on the carpets — it brings them out.
