I can vouch for the bucket/roller design. I quit counting after trapping over 20 mice in less than a year in the house. Once we had them cleaned out of the area, we have had very few. Then I had infestation in the garage last year. This is a separate building from the house. I cleaned up 4 nests and washed down the workbench with bleach. It was a mess. I had not set up the bucket/roller trap previous to this. I set up the bucket trap and got the nesting pair right away. Then I got a small mouse after that. Now I have had no mice in the garage. The bucket makes it easy to dispose of also. I highly recommend this approach--no poison.
