In a seventy-unit residence in Pantin, the contractor visits four times a year. Between visits, it is the caretaker who opens the bin room every morning, who sees the torn bag of rice at the foot of the refuse chute, who notices that a glue board laid in the cellar has been full for three weeks. He mentions it to the residents' committee in a corridor, nobody writes anything down, and the contractor discovers the problem two months later — with two generations of rodents already ahead.
In Paris-region multi-occupancy buildings, the factor that most influences the final cost of an infestation is neither the product used nor the number of visits: it is the time between the first visible sign and the written report to the contractor. And that delay depends almost entirely on one person: the caretaker, the building employee or the cleaning company's maintenance agent. Yet this role is almost never written down. Not in the job description, not in the cleaning contract, not in the rodent control contract.
This article describes what building staff can do, what they are legally not allowed to do, how to set up monitoring that takes ten minutes a week, and how to protect the employer — the owners' association or the landlord — in the event of an accident or dispute.

Why the caretaker is the building's only permanent sensor
A contractor sees the building 4 hours a year, the caretaker 1,600
A standard annual contract in a condominium provides for three to four visits of one to two hours. That means, at best, eight hours of professional presence a year. A full-time caretaker, by contrast, moves through the common areas, the cellars, the bin room and the landings all year round. He knows the usual smell of the basement, the normal sound of the mechanical ventilation, the normal condition of the service door threshold. This is exactly what integrated pest management calls monitoring: detecting a deviation from normal as early as possible.
The signs that matter are nearly all visible to someone who passes by every day:
- fresh droppings (black and shiny) against a skirting board or in the corner of a technical room;
- grease marks and rub marks along a cellar wall;
- bin bags systematically pierced in the same spot;
- fresh soil or rubble pushed out at the foot of a buried wall;
- cockroaches visible in daylight in a duct or refuse chute room, which already signals an established population;
- a persistent ammonia smell in a closed room;
- bait consumed or a bait station moved between two visits.
What the caretaker detects that nobody else can
Three pieces of information appear in no contractor's report and exist only in the building staff's head: the chronology (since when), the precise location (which stairwell, which cellar, which chute) and occupant behaviour (who feeds the pigeons, who stores cardboard boxes in their cellar, which shop puts its waste out the evening before). These three elements are often worth more than a paid-for inspection. But they still have to be recorded somewhere, and not in a lift conversation.
What building staff are not allowed to do
This is the point most managing agents and property managers overlook, and it directly engages the employer's liability.
Rodenticide biocides are not cleaning products
The application of professional-use biocidal products — anticoagulant rodenticides, insecticides against cockroaches or bed bugs — is governed by the Certibiocide scheme (articles R. 522-16-1 et seq. of the Code de l'environnement (French Environment Code), decree of 9 October 2013 as amended). It requires individual certification, a registered company, products authorised by ANSES with a marketing authorisation number, and traceability of applications.
In other words: a caretaker cannot buy rodenticide blocks and place them in the cellar "while waiting for the visit". This act creates three cumulative risks:
- Risk to people and animals. Bait outside a secured station, accessible in an open cellar, is a potential domestic accident. The poison control centre and vets treat anticoagulant poisonings in dogs every year.
- Risk to the employer. The employer must assess chemical risks and provide protective equipment (articles L. 4121-1 and R. 4412-1 et seq. of the Code du travail (French Labour Code)). Having an untrained employee handle a professional biocide is an organisational failure.
- Technical risk. Bait scattered without a plan creates diffuse consumption that makes the contractor's monitoring unreadable and may encourage avoidance of the official stations.
A simple rule to write into every job description: building staff observe, clean, seal mechanically and report. They apply no professional biocidal product.
Cleaning after an infestation is not ordinary housekeeping
Dry-sweeping rodent droppings or vacuuming soiled insulation with a household vacuum cleaner puts potentially contaminated dust into the air. Urban rodents carry leptospires (in their urine), and Santé publique France (the French public health agency) records several hundred cases of human leptospirosis a year in mainland France. Heavily soiled premises require a dedicated protocol, described in our article on disinfection after a rodent infestation.
What the caretaker can do without difficulty, however, with the right equipment: dampen before collecting, wear disposable nitrile protective gloves and an FFP2 mask, use a sealed bag, wash hands and disinfect equipment. These instructions must be set out in writing, and the equipment must be supplied by the employer — not bought by the employee.
The monitoring protocol that takes ten minutes a week
A useful system does not require three days of training. It requires a written round, always the same, always at the same time.
The weekly round of hotspots
In a standard Paris-region building, the list of points to check fits on one page:
| Checkpoint | What to check | Frequency |
|---|---|---|
| Bin room / refuse chute | pierced bags, droppings, floor cleanliness, door closure | 2×/week |
| Meter room and technical rooms | droppings, open sleeves, rub marks | 1×/week |
| Cellars and cellar corridors | cardboard on the floor, disturbed soil, smell, broken cellar doors | 1×/week |
| Bike and pram room | forgotten food, paper nests, gnawed cables | 1×/week |
| Air bricks, ventilation grilles, service door thresholds | loose grille, gap under the door, torn mesh | 1×/month |
| Contractor's bait stations | station present, closed, not moved, label legible | 1×/month |
| Base of façade, courtyard, area around the bin room | burrows, 4–6 cm holes, litter on the ground | 1×/month |
A powerful rechargeable torch radically changes the quality of this round: in a cellar corridor, 90% of the signs are invisible under the original lighting. For high-level points or ducts, the moisture meter and endoscope camera used by plumbers makes it possible to look behind boxing without breaking anything.
The entry points the caretaker can handle himself
Mechanical sealing is not a regulated activity. A building employee can perfectly well replace an air brick grille, fit a door-bottom strip, or fill a sleeve opening. Standard materials — stainless steel wool for rodent-proofing, repair mortar, stainless steel grilles with 6 mm mesh, metal door bottoms — cost a few tens of euros and durably block the most-used routes. The detailed method, order of operations and materials to avoid is described in our guide to sealing entry points in apartment buildings.

The reporting form: the document that changes everything
What it must contain
A report a contractor can actually use fits on seven lines:
- date and time of the observation;
- precise location: building, stairwell, floor, room, compass point or cellar number;
- type of sign: droppings / tracks / noise / live animal / dead animal / material damage / bait consumed;
- quantity or intensity: a few droppings, abundant, repeated in the same place;
- estimated age: fresh or dry, first time or recurring;
- time-stamped photo;
- action already taken: cleaned, sealed, nothing.
A simple rugged site notebook with moisture-resistant paper is enough for the paper version; most property managers today prefer a shared form filled in from a phone. The essential point is that every report carries a date and an identified recipient: property manager or contractor, never "the residents' committee" in general.
Why written records also protect the condominium
In a dispute with an occupant, a ground-floor shopkeeper or a municipal health department, the question is never "were there rodents?" but "what did you do, when, and can you prove it?". The caretaker's reports, filed with the intervention reports and visit slips, form the core of the file. We set out which documents to keep and for how long in our article on the pest control health register. Conversely, a string of verbal reports with no follow-up helps demonstrate a failure to act, as illustrated in our article on formal notice to the managing agent.
Training staff: who pays, how long, on what
Half a day is enough, and it is funded
Training in recognising signs of pests does not fall under Certibiocide. It comes under standard vocational training, funded by the sector's OPCO (skills operator). For caretakers and building employees covered by the national collective agreement for caretakers, concierges and building employees (IDCC 1043), workplace health and safety measures are ordinary running costs of the owners' association, voted by the majority set out in article 24 of the law of 10 July 1965.
A useful programme fits into four blocks:
- Recognise: tell brown rat droppings from mouse droppings, identify the German cockroach, spot bed bug traces on a landing or in a laundry collection room.
- Understand the routes: vertical networks, ducts, risers, crawl space. A look at our article on service ducts provides the right framework.
- Act within your remit: bin room cleanliness, tidy cellars, simple mechanical sealing, personal protection.
- Report: to whom, how, within what timeframe, with what information.
A practical pest control handbook and a laminated sheet posted in the caretaker's lodge are worth more than a forgotten PowerPoint deck: signs are recognised by visual comparison, not from memory.
The case of contracted cleaning companies
In most Paris-region condominiums, there is no longer a caretaker but a cleaning company that comes two or three times a week. The right reflex is contractual: add a line to the schedule of services reading "written report of any sign of pest presence in the common areas, within 48 hours, to the property manager". Without that line, the agent who sees droppings has no obligation to say so, and will not say so. This link between the cleaning contract and the pest control contract must be thought through from the drafting of the service specification onwards.

The five most common mistakes
1. Putting the caretaker in charge of rodent control "to save money"
This is the costliest mistake. It transfers a regulatory risk onto an employee, deprives the condominium of any usable traceability, and almost always leads to a wider infestation six months later.
2. Asking him to open flats when occupants are absent
The caretaker sometimes holds keys for technical emergencies. Using them to let an applicator in without the occupant's written consent is a violation of the home. The correct procedure, including letters and deadlines, is described in our article on refusal of access to a dwelling for treatment.
3. Not passing on the contractor's reports
The caretaker is the only person able to check that the recommendations have been carried out: grille replaced, station put back, room cleaned. If he does not receive the report, nobody checks anything. Critical reading of these documents is covered in detail in our guide to the intervention report.
4. Leaving him alone to face the occupants
Announcing a treatment, asking someone to empty a cupboard, explaining a bed bug protocol: these are tense exchanges. The letter must come from the managing agent or the landlord, on headed paper, with the dates and the contractor's name. The caretaker relays the message, he does not decide.
5. Forgetting his own working conditions
A lodge at courtyard level, a service room adjoining the bin room, a changing room in the basement: building staff are often the first victims of the infestation they report. The employer owes them a healthy workplace under the Labour Code, and this obligation also applies to the cleaning room and the changing room.
The right set-up, in summary
| Party | What they do | What they do not do |
|---|---|---|
| Caretaker / building employee | monitoring round, cleanliness, simple sealing, written reporting | applying biocides, deciding on treatment, entering dwellings |
| Cleaning company | cleanliness of waste collection rooms, contractually agreed reporting | inspection, treatment |
| Managing agent / landlord | job description, training, PPE, ordering interventions, letters to occupants | delegating treatment to staff |
| Certified pest control contractor | inspection, secured baiting, insect control, report and recommendations | daily monitoring |
The added value of a properly framed caretaker role is easy to quantify: in a building where written reporting exists, an emerging infestation is dealt with in one or two targeted interventions. In the same building without reporting, the same emerging infestation is discovered when occupants on the upper floors complain — that is, after the ducts have been colonised, and a plan running over several months is then needed.
If you are a managing agent, property manager or landlord and want to formalise this system — job description, round, reporting form and alignment with an annual contract — our annual monitoring contracts include training for building staff and the supply of reporting materials. For a building that is already affected, a costed inspection makes it possible to separate what relates to the building fabric, to cleaning and to treatment.
