Do house mice carry lots of diseases?
All wild animals CAN carry diseases, but that doesn’t mean every single mouse you see will be disease-ridden. Mice and rats in particular get a bad press, possibly because they live close to humans more often than most other wild animals, but they don’t carry any more diseases than rabbits or hedgehogs or anything else. I’d suggest you buy some live traps, which catch the mice without killing them, and then release them outside.
