I have been able to get rid of them at our farmhouse, even when we bushhog, by using a combination of peppermint & cinnamon oil. I purchased a spray off Amazon but have seen it at Ace Hardware. It can be sprayed or saturate cotton balls. Place around and make sure to re-apply as the scent fades. They don’t like the smell. I’ve been told it can be toxic to pets.
Keep the property as tidy as possible with no places for them to hide, nest and breed. A problem where I live too. You just need to be diligent. Here are some things you can try.
Just be careful with any remedy, whether home made or purchased if you have pets or children. Luckily I have a Doberman/ Terrier mix that is a better mouse and rat catcher than all 6 of my semi feral rescue cats combined.
Talk to them in a condescending manner and tell them they are worthless. After a while they will be discouraged. I just have to be flippant ever once in a while.
Tell them that the grass is greener on the other side of your fencing!🤔🐿
