Why the whole building?
In an apartment building, the flats are not separate spaces: service ducts, cable runs, the ventilation system and structural gaps connect them. Cockroaches and bed bugs travel through these.
That is why treating a single flat does not work: the population survives the intervention next door and returns once the product’s effect wears off. An infestation in an apartment building can only be cleared in one pass, covering the whole building.
Hotspots
Cellars, service ducts, the rubbish chute and the refuse room are usually the most heavily infested points. Treatment must always cover these, even if the report came from a single flat.
Resident notices
Full coverage is what makes treatment succeed. Before treatment, we hand the building manager a written notice; it states the date, the preparation needed, and the length of the re-entry interval. We document the flats that were missed, because these carry the risk of the problem returning.
Who do we contract with?
In an apartment building, we contract with the building itself through the building manager, or with the facility management provider operating the building — not with individual flat owners. This is not a business decision but a technical one: pests move freely between the flats, the cellars and the ventilation system, so treating a single flat on its own does not lead to a lasting result. A few weeks after payment, the problem returns from next door.
For a self-contained property — a house, a standalone commercial unit — we of course contract directly with the owner.
Billing
We give the residents’ association a transparent account: the number of flats treated, the interventions carried out, the products used and the result of the follow-up check — in a form that can be presented to the general meeting.
