Our house was built in 1896 and is brick on the lower level and vinyl siding on the upper level. Since we have lived there, about 20 years, we have heard movement and scratching in what seems to be in the walls above and beside our heads in our upstairs bedroom and above us in other rooms upstairs. We have set bait for mice in the attic, but it seems untouched and we never see signs of any mice either up in the small attic space or in our home. Any ideas what these creatures might be or how we can find out? Mary
