Many people regard mice as harmless, even endearing, animals. Yet the presence of mice in a home is a serious problem that should never be taken lightly. These small rodents are responsible for considerable material damage, food contamination and real health risks. Here is why you need to act quickly if you suspect they are in your home.
The house mouse (Mus musculus) is one of the most prolific mammals in the world. A female can breed from the age of 6 weeks and give birth to a litter of 5 to 12 pups every 3 weeks. This means that a single female can produce up to 10 litters a year, or between 50 and 120 pups. These young mice are themselves able to breed within a few weeks. In theory, a pair of mice can produce a population of several thousand individuals in a year. That is why treatment at the first signs is absolutely crucial: every week of waiting multiplies the scale of the problem.
Mice have incisors that grow continuously throughout their lives. To wear them down, they constantly gnaw at everything in their path. Electrical cables are one of their favourite targets, which represents a genuine fire risk. It is estimated that 20 to 25% of house fires of unknown origin are linked to rodents damaging electrical wiring. Mice also attack plastic pipes (risk of water damage), insulation materials (reduced energy performance of the building), documents and books, and even wooden structures. The damage can amount to considerable sums in repairs.
Mice carry many diseases that can be transmitted to humans. Leptospirosis, transmitted through rodent urine, can cause serious kidney and liver failure. Salmonellosis is contracted by eating food contaminated by their droppings. Hantavirus, although rarer in France, is transmitted by inhaling dust contaminated by dried excrement. A mouse produces around 80 droppings a day and urinates continuously along its routes. These biological traces end up on your worktops, in your cupboards and on your food. People who are immunocompromised, children and elderly people are particularly at risk.
A mouse can squeeze through a hole just 6 millimetres in diameter, the equivalent of the diameter of a pencil. They exploit the slightest cracks in walls, the gaps around pipes, the openings under doors and faulty seals to get into your home. Once inside, they set up their nests in hard-to-reach places: between partition walls, in false ceilings, under baths, behind household appliances or in insulation materials. This ability to hide explains why many infestations are only discovered at an advanced stage, when the population has already reached significant proportions.
Faced with an infestation, many people try to solve the problem with shop-bought mousetraps. While these devices can catch a few individuals, they are far from sufficient to eliminate an entire colony. Mice are intelligent and wary animals: they quickly learn to avoid traps after seeing one of their own kind caught. What's more, traps only treat the symptom and not the cause: without identifying and blocking the entry points, new mice will take the place of those caught. Ultrasonic devices sold as repellents, for their part, have no scientifically proven long-term effectiveness.
A professional rodent control treatment combines three complementary actions for a lasting result. First, a full assessment of the building identifies the species present, their runways and the entry points. Next, setting up secured bait stations eliminates the existing colony using professional delayed-action rodenticides. Finally, sealing up the entry points with rodent-proof materials prevents any re-entry. At Mr Nuisibles, our certified technicians follow this rigorous protocol and provide post-treatment follow-up.
