I had the same problem about this time last year. Check out Dallas' solution ---brilliant!!"It's kind of mean and probably not politically correct at all, but my dad taught me how to get rid of mice.fill a bowl with 1/2 cup of corn meal and 1/2 cup of plaster of paris and a teaspoon of salt.Mix Well.Place in corner away from lights and noise. (Mouses like peace and quiet to eat).Next:Fill another bowl with water.Place bowl about 3-4 feet from bowl of cornmeal mix.Return everyday and pick up dead mice.The mice eat the cornmeal, salt and plaster of paris and get a huge thirst.They see the water a little way away and go to drink. The distance gives the mix a chance to work a little.When they drink, the mix heats up and hardens. Mouse dies from severe constipation.It use to work in our chicken houses and sheds all the time.YMMVIHTHDallas"
