Mice are not my problem, its the pack rats! They got into my wife's Dodge Ram built a nest in the fan blower, they got the wires on the round baler. I have placed rat bait in every corner of the barn, in the air cleaner of her truck in hidden portions of the baler and I keep WASP SPRAY on hand.
Last spring they got in the boat !! We take our annual spring fishing trip over spring break. Got the camp all set up, and hit the open water ... got to our favorite spot, handed the wife her rod and I started setting up, she says "hey what happen to my line?" I said I'll fix you up here take mine ... and yep it too was ate up. I told her must be a rat on board she gets up on her seat and says "If you don't get this boat to shore I will be running on water!!"
On shore I empty the boat and find the nest ... no rat ... out we go again and in awhile she hears noise and is determined there is a rat on board, back to shore. A neighbor friend who was also camping and fishing came in, asked what was wrong with the boat, cause we have been going out and coming back in, I explained it and he says I'll get him out.
He comes out of his camper with Wasp Spray ... confused I tell him its not wasp its a rat, he says watch this ... opens one of the doors in the floor and sprays all the can in the boat, closes the door and waits and sure enough in a few minutes out comes the rat!! He tells me the spray uses up the oxygen and forces the rat out.
So anyway around here its bar bait and wasp spray and if I got one in an area that I need to flush him out I spray em!!!!
