Mice In Pittsburgh

Has anyone else in the Pittsburgh area noticed an increase in house mice recently? I was talking with a local exterminator, and he mentioned that he has seen a rise in calls about mice, particularly in parts of the South Hills and in homes surrounded by wooded areas. My house is kept pretty clean, but we still had mice this past winter. We had our first mouse about three years ago, then nothing until now, and suddenly they’re back again. I’m curious if other homeowners, especially those living near woods or green spaces, have experienced something similar. Has anyone else noticed an increase in mouse activity over the past few years?
To add some context, the mice were actually showing up on the upper floors of the house rather than the basement. That’s what surprised me. We had our first mouse about three years ago, then nothing for years, and now they’re back again. Our home is surrounded by wooded areas, so I’m wondering if others in similar locations have experienced the same thing recently.
