So we have mice in the house. We periodically do, especially in winter, and we typically put up traps and the like and for many years we had cats, which kept the numbers low, but even without the cats I doubt we have more than a few at any given time. My question is, should I be considering the presence of mice in the house as more of a health risk and be doing more/contacting an exterminator to get rid of them? In particular I'm worried about their droppings and the like, as we have many small corners it's hard to keep clean and I sometimes leave clothes lying around at night, and I know they've been in my closets. I've always assumed that mice are pretty common and a lot of people will have some every once in awhile, them being hard to keep out on a permanent basis, but recently I've been concerned I should be a lot more diligent about controlling them and cleaning when they're around than I have been.
