Greg Flynn of Braemar Pest Control Services tells CHSJ News snow around your house tends to fill in the areas outside your home where mice might get in but he warns they don't need much room to get inside.
He tells us mice only need a quarter of an inch so basically a space the size of a dime to get in adding they can compress their bodies to fit in a very small hole.
Flynn says in the City they mostly see what they call a "house mouse" but in the outlying area you see field or deer mice.
