Its a banner winter for mice. For the past few weeks I have been trapping a bunch in my motor home, garage, and shed. I bought some of the Black & Decker ultrasconic transmitters. I have three in my motorhome, a couple in my shed and a couple in my garage. I thought they might be working early on but they don't work for poop.
I killed 14 mice in my motor home with old fashion traps in just the last two weeks.

I can't believe it! All I can say is that I hope they are going for my peanut butter first and not my wiring.
I also made a prototype bucket trap with a ramp, dowel and a spinning tube which is in my garage. I have drowned a few mice in it. Works pretty good. Cats have caught a few too. How's everyone else making out.
