Rodent control — Mice in Paris & Île-de-France — SOS 4D Paris

Against mice, the protocol prioritises a dense grid of devices (mice travel little): mechanical trapping, secure TP14 bait stations when the context allows, dusting of partition paths and, above all, systematic sealing of 6mm access points, as part of an Integrated Pest Management (IPM) plan.

The house mouse (Mus musculus) measures 7 to 10cm and weighs only 15 to 25g. It nests as close to food as possible: partitions, wall linings, under appliances, false ceilings, kitchen cupboards and storerooms. Unlike the rat, it nibbles little but very often (up to 200 food intakes per day) and constantly explores its territory, limited to a few metres. Its reproduction is explosive: 5 to 10 litters per year, 4 to 8 young per litter, mature in 6 weeks.

A mouse enters through a 6mm hole: door thresholds, pipe passages, disjointed skirting boards, ventilation grilles without mesh, electrical ducts. Infestations often start after works, a delivery of boxes or pallets, or in autumn when the cold pushes mice towards heated buildings. Poorly stored food, crumbs, pet kibble and open bins are enough to fix a population permanently.

Mice leave small black droppings 3 to 6mm long, rice-grain shaped, scattered in drawers, under the sink and at the back of cupboards. You also observe packaging gnawed into clean small holes, nests made of shredded paper or insulation, a characteristic musky smell in partitions, and slight scratching noises at the beginning of the night. Seeing a mouse in the daytime already signals a significant population.

Mice lodge in partitions and wall linings, behind and under appliances (oven, dishwasher, refrigerator), in false ceilings, kitchen cupboards, storerooms, false floors and technical boxes. Their nests are almost always found less than 3 to 5 metres from a food source.

Mice contaminate food and surfaces with their urine and droppings (salmonella, hantavirus, leptospires), trigger respiratory allergies and gnaw cables and electrical insulation. In food businesses, the slightest dropping found during a hygiene inspection can lead to non-compliance or even administrative closure.

Prevention relies on sealing every opening larger than 6mm (steel wool, mortar, brush door sweeps, fine mesh), storing food in airtight containers, cleaning crumbs and grease behind appliances, daily bin management and checking box deliveries. Periodic monitoring is recommended for catering and food retail.
