That surprises me. We have some traps for 4 years. If you used peanut butter, don’t. You need pieces of something dry, cookies, bread, pie crust. The oil from the peanut butter shorts them out.
I don’t remember what Mr. T. used, but we are currently mouse-free. I think that as long as we keep the entryway closed, we will be all right. This house is circa 2002 at completion, so we don’t yet have any foundation cracks that we have seen. That’s important. Our first house was built right after WW2.
Now that I think of it, Mr. T. probably used peanut butter, although I can’t be sure.
