I have lived with deer mice in different places all over the country, and many of my friends and family have (and still do).
Let me say first that I’m only addressing hantavirus because I skimmed your post history, and not because it immediately came to mind as threat-level-red-tier information. In Oregon, hantavirus is quite rare. There have been fewer than twenty cases in over twenty years. If it makes you feel better (which I hope it does maybe), I am a healthy woman in my thirties who (before I was aware that there was danger) has swept up and even vacuumed Oregonian mouse shit many times, and I live to tell the tales. I know anecdotes aren’t data, but I’m talking dozens.
That said, mice can be very destructive. If you are renting, you’ll need to let your landlord know if you’re concerned that there may be an infestation. If you’re a homeowner, you’re going to want to spend the money that you need to spend to hire a professional pest management company. They can chew their way into fire hazards and thousands of dollars of damage — and that is the much more common fear with these creatures, and it’s worth an expert’s opinion and equipment to deal with the problem.
I know it probably sucks to be dealing with mice right now — especially since masks and gloves and bleach and the whole heynana would ordinarily be in easy supply — but I think you’re gonna be okay. Take a hot shower, some deep breaths, sip some tea.
