Is It Possible to Have Only One Mouse?
A single mouse is a rare occurrence, but the mouse might be alone if the weather has been cold. On average, most mouse sightings indicate a more significant infestation, so having a solitary mouse in your home is pretty rare.

Is there ever just one mouse in your house?

In reality, the chance of there only being one mouse in your house is very small. Mice live in family groups that are made up of one dominant male, one or two females, and their young. When a mouse gets into your house, it will not move in alone.

Does one mouse mean an infestation?

However, one mouse will almost always lead to an infestation if control methods are not put in place. One pregnant female mouse can produce as many as 10 litters in one year, so it's easy to see that one mouse will soon become many mice unless an effective Integrated Pest Management (IPM) is put in place.
