A female can give birth to 5 to 15 litters per year. The gestation period is 18 to 21 days and there are generally between 5 and 12 pups per litter. Vectors of diseases which are present in their excrement, urine and saliva and can be a major danger to your health. Rodents feed on your reserves and munch on food from your pantry. They soil their urine and feces with everything on their way: kitchen counter, linen, food, etc. They imbue their environment with foul smells.

They are often heard walking around late at night or very early in the morning or even at night, when everything is peaceful in the house. Unfortunately, it sometimes happens that they gnaw on the sheath of the electric wires, leaving them bare and this could cause a risk of fire. There are very effective ways to combat them, however their implementation is always tricky and can be dangerous for people and pets.
