How long does the back-to-work audit take?

90 minutes on average for a 200-500 m² office, up to 3h for a condominium with collective waste room or a full school. Written report within 6 hours.

Do offices need to be emptied before the audit?

No, the audit is done with normal furniture and document presence. We only ask for access to technical rooms (back of cupboards, ducts, false ceilings if visible signs).

Do schools need systematic treatment at return?

No, an audit is enough in most cases. Treatment only if signs detected (rodent droppings, cockroach corpses, positive pheromone traps). HACCP collective catering however requires annual traceability of a documented audit.

Can you intervene outside working hours?

Yes, systematic for schools/day-cares and common for offices/condominiums (weekday evenings 6-10pm, Saturday mornings, Sundays on request).

Is the audit report usable for insurance?

Yes. Our report contains: Certibiocide number, date, points inspected (annotated photos), risk level per zone, recommendations. This signed PDF evidences your vigilance (HACCP or co-ownership); if a treatment is carried out, the treatment certificate documents the intervention for your insurer, who alone decides on cover.

Back to work in Monaco: preventive audit for offices and schools

Offices closed 3-5 weeks in August, schools empty since late June: pests had all summer to settle in. Our 90-minute back-to-work preventive audit.

The first 3 weeks of September in Monaco mark the return for most offices, banks, firms, schools, day-care centres and condominiums whose residents return from holiday. These buildings have been empty or on minimum staffing 4 to 8 weeks — an ideal period for opportunistic pests exploiting the absence of human traffic, retained heat and food stocks left in place.

Three typical back-to-work pest categories

1. Rodents (mainly mice)

The house mouse tries to enter buildings as soon as September night temperatures drop. An empty office in August = unobstructed route. Signs visible at the return: small black droppings (2-3 mm) in drawers, gnawed skirting boards, chewed network cables, punctured coffee/sugar bags.

2. Cockroaches

Colonies already established have proliferated quietly in August. Corporate kitchen restaurants and condominiums with waste rooms present the highest risk. A cockroach crossed the first Monday of return = colony already at 500-2000 individuals hidden in ducts and false ceilings.

3. Ants and food moths

Argentine ants establish trails towards the slightest forgotten sugar source. Food moths (8mm beige butterflies) emerge from cereal or flour packs left in company kitchens. Return = signalling peak.

Our back-to-work preventive audit — 90 minutes

For businesses and condominiums resuming activity mid-August to mid-September, we offer a standardised preventive audit:

On-site visit in 1h30 by a Certibiocide technician
Systematic inspection of critical points: waste room, kitchens, sanitary facilities, crawl spaces, technical ducts, archives, server room
Instrumental detection: pheromone traps (cockroaches + moths), sticky traps (rodents), UV lamp (rodent fluid)
Written report within 6 hours: risk level per zone, recommended corrective actions, follow-up schedule
Intervention quote attached only if positive detection — the audit itself is free and without obligation

Who to contact in priority

Priority (contact before end of August): - Corporate restaurants and school canteens - Condominiums with collective waste room - Hotel kitchens resuming corporate activity - Medical offices with paper archives - Nursery schools and day-care (legal HACCP obligation for collective catering)

Recommended: - Offices with cafeteria/meal corner - Law firms / notaries (rodents on archives) - Condominiums > 20 units

Specific school / day-care protocol

Educational establishments have particular constraints: - No residual biocide in rooms where children circulate - Interventions outside attendance hours (evenings, weekends, Wednesdays) - HACCP-compliant certificate for collective catering - Coordination with the hygiene officer of the establishment

We have a dedicated protocol for Monegasque and Alpes-Maritimes schools/day-cares, compliant with National Education requirements and the Decree of 21 December 2009.
