There are disease issues of which you should be cautious. These would be transmitted by exposure to the droppings, urine, or bedding, or by being bitten or scratched by a mouse. There are some ticks that live on mice.
That said, outdoor mice are difficult to control. And, disease transmitted from outside mice is very rare- I could find no references that discussed it. A few mice are a natural part of the ecosystem. Hawks and other birds of prey, and neighborhood cats, are ‘natural’ controls. Populations will fluctuate based on weather and food supply, too.
Do be diligent about keeping them out of your living spaces. This is where, after an accumulation of the above mentioned contaminants, people most often can be exposed to disease. If you have to handle any material, including a dead animal, be sure to wear disposable gloves and a mask. If you have a compost bin watch that mice do not start invading it. You will have to screen it off, and trap the mice there, if they are present in your bin.
I am including articles that discuss details of control and cleanup should you need them in the future. Thanks for being eco-friendly! and for using our service.
