Are you kidding ? it’s in the GARAGE!!
What did the LL do wrong ?
Where I live, there are spiders, mice, rats, bats, coyotes, snakes, ants, hummingbirds, orioles, hawks and an occasional mountain lion in the ‘hood
The species were all here before the house was built.
Only the critters with good taste (or an education) want to live in an upscale community.
I’ve been a landlord for about 25 years. I would tell you to get some traps. The mice were probably in the area before you moved in.
Do you realize how much your landlord is probably losing every month by renting to you ?
I’m a better landlord than most, but won’t put up with “demanding” tenants.
If you want to hire an exterminator, they will set traps or spray and when the critters return they will charge you to do it again.
If you OWNED the house, do you think that a mouse wouldn’t appear ? You going to complain to the lender and demand they get rid of it or you are outta there ?
