The CDC and www.hantavirus.net sites seem to think it is confined to

Getting back to the OP, I wouldn't bother unless you are finding signs
of damage from them. You've already killed 50 and they are still being

other predators this winter?

If they get into your home thats another matter, as they will find and
contaminate your food and are not averse to chewing the odd power
cable...
