I've got mint by a garage and my house on one side, had a mouse for the first time this winter but he may have come in from the drain pipe in the basement
Heavens no I don't have any mint in my herb garden it's bad enough with the wormwood and oregano, wish I didn't have it by the house but it smells so good when the lawn mower hits it it's chocolate
I had no idea that oregano spreads like it does now I did know about the wormwood
Oregano might be something to look at too.
I found two vole holes in the side yard today! They could be chimpmunks but thinking they are voles haven't seen very many chinpmunks since I got a cat and new neighbors with an outside cat my cat is out in the summer only.
