Seasonal calendar
When to monitor which pest
Pest control is above all a matter of timing. Month-by-month calendar of species to monitor in the Principality of Monaco and on the French Riviera — to act early and save tenfold.
Mild winter
JANUARY — FEBRUARY
Rodents
Rodents seek shelter in heated buildings. An opportune time for a diagnosis and the sealing of entry points before the spring activity peak.
Clothes moths
Wardrobes and dressing rooms are the critical areas in winter. Installation of pheromone traps and inspection of wool and cashmere storage.
Spring awakening
MARCH — APRIL
Asian hornets
Foundresses build primary nests (the size of an orange) at standing height. Destroying a primary nest costs ten times less than a secondary nest in July — act now.
Ants
Colonies emerge from winter dormancy. The first wave of Argentine ants appears in the coastal zone, with pharaoh ants in kitchens.
Tiger mosquito
Season preparation: elimination of larval breeding sites (saucers, gutters, drains). The groundwork is won now.
Start of the tourist season
MAY — JUNE
Bedbugs
Peak importation tied to international tourist flows. Mandatory hotel audit before season opening. Inspection of mattresses, encasements, and training of housekeeping staff.
Cockroaches
Professional kitchens and dark kitchens: heightened HACCP monitoring ahead of Bureau Veritas, SGS and ECOCERT audits.
Pigeons
Nesting period: preventative removal of nests still under construction before they become permanent damage.
Peak season
JULY — AUGUST
Hornets (secondary nests)
Secondary nests (the size of a basketball to a beach ball) at height. Intervention with a telescopic pole, in full PPE, sometimes at night. High risk to bees.
Mosquitoes
Peak activity. Weekly audit of larval breeding sites in co-ownerships and hotels with outdoor areas.
Pantry moths
Long-term stores (flour, pasta, rice) are at risk. Audit of yacht galleys and beach restaurants.
End of season
SEPTEMBER — OCTOBER
Rodents
Rodents seek to enter for winter. Comprehensive sealing audit, inspection of ducts, and preventative installation of secured bait stations.
Hornets (dismantling)
Dismantling of secondary nests at the close of activity. Future foundresses are leaving — this is the right moment.
Cockroaches
As temperatures fall, cockroaches move back into heated areas. Heightened monitoring of kitchens and yacht crew messes.
Wintering
NOVEMBER — DECEMBER
Annual audit
Review of the past year, adjustment of the 360° contract, installation of new sentinel traps, and updating of the risk mapping.
Wood treatment
An ideal period for curative wood-borer treatments: no occupancy, stable temperatures, dry timber.
Hotel turnover disinfection
Between seasons, comprehensive disinfection of rooms, suites and communal areas. Preparation for quality audits.
