What do you do if you find a baby mouse? Call a wildlife rehabilitator.
If you find a baby wild mouse (or an empty nest of baby mice), call your local wildlife rehabilitation office. Transferring the baby mouse to a wildlife professional is the best chance it has for survival. In the meantime, there are things you can do to try to keep the baby alive.
Does 1 mouse mean an infestation? 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.
How did a baby mouse get in my house? Mice enter homes through cracks and holes found in walls, floors and foundations. Homeowners commonly do not recognize mouse holes until other signs of infestation appear. Due to their body shape, mice are capable of fitting through holes much smaller than appear likely.
Does one baby mouse mean more? Though it may seem silly, there could be something to this impulse. One mouse can be something frightening, indeed, because if you see one mouse, there are more. And the more there are, the more potential there is for damage and disease. Mice are small and plentiful, and they are the perfect prey for many predators.
