Flea and mite control in London
Only a small part of a flea population is ever on the animal. The rest is in the carpet, the bedding and the floor joints — which is where treatment has to go.

The problem
What you are dealing with
The cat flea is responsible for the large majority of flea problems in UK homes, including homes with dogs and homes with no pets at all. Adult fleas feed on an animal, but eggs drop off into carpet, bedding, upholstery and floorboard gaps, where they develop through larval and pupal stages before emerging as adults. At any given moment the animal carries only a fraction of the total population.
The pupal stage is what makes fleas frustrating. Pupae are resistant and can sit dormant for weeks or months, waiting for the vibration, warmth and carbon dioxide that signal a host. That is why people moving into a property that has stood empty are sometimes bitten heavily within hours — the previous occupants' pets left a dormant population behind.
Mites are a separate group and the source is usually different. Bird mites come from a nest in a roof void, a soffit or a chimney and move indoors when the nest is abandoned after fledging. That distinction matters: with bird mites, the nest is the problem, and treating the room without dealing with the nest achieves very little.
Signs to look for
Signs of fleas in a property
Fleas and mites are usually identified from bites and from a careful look at the floor:
- Bites concentrated on the lower legs and ankles, often in small clusters
- A pet scratching, biting at its coat or grooming more than usual
- Flea dirt in a pet's bedding or coat — dark specks that turn rust-red on damp paper
- Small dark insects flicking away when carpet or bedding is disturbed
- A sudden onset of bites when moving into a property that has been empty
- For mites: pinprick bites and irritation, often starting a few weeks after birds were active in a roof or chimney
Why it needs doing properly
Why professional treatment may be needed
Treating the pet is necessary but not sufficient. If the carpet, bedding, upholstery and floor joints are left alone, newly emerged adults simply reinfest the animal and the cycle continues.
The pupal stage is also not reached by most products, so a treatment that does not account for continued emergence gives a quiet week and then a second wave. Knowing that in advance is what stops people concluding the treatment failed.
With mites, the critical step is finding the source. If the source is a bird nest in a roof void or chimney, treating the bedroom is treating the symptom — and the nest needs handling correctly, since wild birds and active nests are legally protected.
What the inspection involves
- We identify what is actually biting, because fleas, bird mites and other biting insects need different responses.
- We check where pets sleep, rest and travel, and the carpet, rugs, upholstery and floor joints around those areas.
- We look for flea dirt and for the conditions that support development — carpet pile, under furniture, along skirting, in floorboard gaps.
- Where mites are suspected we look for a source: roof voids, soffits, chimneys, loft spaces and any sign of current or recent bird nesting.
How the treatment works
- Treatment covers the environment — carpets, floor edges, upholstery and the areas pets use — rather than the animal, which is your vet's side of the job.
- We ask you to vacuum thoroughly before and after treatment. The vibration prompts dormant pupae to emerge, which brings them into contact with the treatment instead of leaving them to hatch later.
- We explain that some continued activity after treatment is expected as pupae emerge, and roughly how long that should last before you call us.
- For mites, the recommendation deals with the source as well as the affected rooms, and we will tell you where a nest needs to be handled by someone qualified and at what time of year.

Preventing it happening again
Treatment deals with what is there now. These are the things that reduce the chance of it coming back.
- Keep pets on a regular veterinary flea treatment, especially through the warmer months.
- Wash pet bedding at a high temperature and vacuum the areas pets rest in regularly, including under furniture.
- Vacuum floor edges and the gaps between floorboards, not just the open floor.
- Proof soffits, roof voids and chimney openings against bird nesting — outside the nesting season, and with advice if you are unsure.
- If you are moving into a property that has had pets and stood empty, vacuum thoroughly on arrival.
Fleas in London properties
London flats with carpeted communal stairs and shared entrances can carry a flea population between units, and foxes moving through gardens and under decking are a regular source in ground-floor and garden flats. Bird mites turn up most often in older properties with open chimneys, worn soffits and accessible roof voids, which describes a great deal of London housing.
EVO Pest Control works across London and nearby areas, in homes and in commercial premises, from 1 Fulham Palace Rd, London W6 8AB.

Fleas — common questions
If your question is not here, call and ask. It is a quick conversation and it usually saves a visit either way.
07886 109682Fleas can be left behind by previous occupants' pets and remain dormant as pupae for months, emerging when someone moves in. They also come from foxes and cats passing through gardens, under decking or into outbuildings.
Yes. We treat the environment; the animal itself is your vet's side of it. Doing only one of the two is the most common reason a flea problem drags on.
Pupae are resistant and continue to emerge for a period after treatment. Some activity afterwards is expected. We will tell you roughly how long that should last and at what point to call us rather than wait it out.
Fleas come from mammals and live in carpet and bedding. Bird mites come from a bird nest — usually in a roof void, soffit or chimney — and move indoors when the nest is abandoned. The treatments differ, and with mites the nest has to be addressed or the problem returns.
Yes, thoroughly, and again afterwards when we tell you to. Vacuuming prompts dormant pupae to emerge, which is exactly what you want them doing while the treatment is active.
