@Andrew1050 Make mention of it in your listing description, i.e. "This listing is in a natural area, where wildlife is present. Field mice are common and attracted to any food left out, and can scurry in unnoticed when the door is left open. We advise to not book here if possibly seeing a mouse will cause you distress."
It's much better to head off the guests who will have a melt down and leave bad reviews than to feel worried about it. That goes for all listings- no place is perfect- some are noisy, some are in areas with lots of insects, some have lots of stairs to climb. Mentioning the warts along with the attractions is a good idea.
I'd also put a framed note on the wall in the kitchen, with a cute graphic of a mouse, and the warning to not leave out any food and to keep countertops clean and sweep up any food that falls on the floor. Provide well-sealing containers for guests to store whatever non-refrigerated food they have.
And do your part as far as using mouse traps and such. Having a feral cat around (spayed female) would also be great. I have a cat who was feral in my neighborhood for a couple years until she decided one day that my outside chair cushions were real cozy. So I resigned myself to her even though I'm not a cat person. She is an awesome mouser and has decimated the rodent population around my place. She leaves me "gifts" all the time.
If you are going to be checking guests in personally, you could use my strategy, as I live in the tropics where the insects are prolific. When orienting guests around, I just drop it in casually - "So as this is the tropics, there's ants, spiders, roaches, scorpions, etc. Of course I've cleaned your room thoroughly, but those critters can come in easily- make sure not to leave any food, or food wrappers out and shake out your clothes and shoes before you put them on. Now here's the light switch for the bathroom...."
I find if I talk about it casually, because it is a fact of life here, that guests take it in stride. If you make a big apologetic deal of it, guests are more likely to use it as cause for complaint.
And if anyone mentions it in the review, you can leave a response that makes it clear that you are very forthcoming about the local critters in the area and that the guests booked fully aware of that.
