I hear mice in the attic of my rural brick ranch. The roof is a hip with large slatted wooden vents on each end at the ridge,with stapled fine screen wire. I've checked all the utility holes.Rechaulked them. I'm thinking around that vent screening. The house has 24" overhangs. Somehow the mice must be climbing the big outside chimney getting on the roof.Then gaining access around this screening. I've placed snap traps unstrapped then fixed them later. No luck. Anyone try different measures like some kind of smelling oil? I've checked net. Something you guys find works. My cats do get one occasionally. Thanks
