We were raised in the country and the field mice were pretty much a part of life- poisons were not an option due to all the critters we ended up with. Mom tried every old wife's tale she read or heard about. They ate through Tupperware. Well Mom's solution was ''if you can't beat 'em- feed 'em. They seemed to enjoy my brothers corn flakes the most so she kept them supplied in corn flakes. Old coffee cans filled with flakes along the edges of the yard. After that it was very rare we seen a mouse in the house-which only meant they were out of flakes. Fill the can 2/3 and put the lid back on with only 1 knife slit close to the edge of the lid so they can smell the goodies-they will chew their way in-Mom said they need the challenge--aka--mouse sy-col-ogy --lol. We all still do this and it still works. Buy the biggest cheapest box of flakes and you are still saving tons of money and you are not killing any of God's little critters. We believe if you ain't going to eat it -don't kill it.
