Treat one flat in a shared building and you’ve usually treated a quarter of the problem. Mice moving through a service duct, or rats working a shared basement under six flats, don’t respect the boundary between one tenancy and the next, so pest control that only looks at the flat where droppings were spotted tends to miss the actual route entirely.
Crittorz works with landlords, letting agents, and HMO managers across London and the South East on that basis, treating the building as a whole where that’s what the problem actually calls for, not just the unit that happened to complain first.
Landlord and HMO jobs are quoted per property, based on layout and unit count.
A lot of London's housing stock is exactly the kind of building this problem thrives in, Victorian terraces split into flats, converted properties with gaps between original structure and later additions, shared basements with pipework nobody's fully mapped. Mice can move through cavity walls and service ducts most tenants never see, which is why a single flat's infestation is often a symptom of something wider in the building.
Rather than treating each flat separately, we identify the routes being used across the building, shared risers, gaps around communal pipework, basement access points, and close those off as one job. It's more work upfront than a single-flat callout, but it's the difference between solving it and doing the same job again in three months when it turns up in a different flat.
Pest issues in rented properties often come with a legal angle attached, particularly where the cause is structural rather than tenant behaviour. Under housing regulations, landlords can be responsible for infestations caused by disrepair, a hole in brickwork, a failed airbrick, rather than anything the tenant's done.
We provide reports that document cause and treatment, useful for tenancy disputes, compliance checks, or simply having something on record if it's ever questioned.
Depends what's actually going on, but for shared basements, service ducts, or multi-let properties, treating the whole building is usually what actually solves it rather than just moving the problem to a different flat.
Generally the landlord, under housing regulations, if it's coming in through disrepair like a cracked airbrick or gap in brickwork. It's a different conversation if it's more about tenant behaviour, bins left open and so on. Worth getting it documented either way.
Yes, a written report covering cause and treatment is provided, which is often exactly what's needed for either situation.
Yes, that's common, and can be set up as an ongoing arrangement rather than a fresh call-out every time something comes up.
Similar principle, but usually with more shared space and higher turnover of tenants, so proofing tends to focus heavily on communal areas and shared service routes.
