Kaput Mouse Block Review
We have used these blocks for mice and voles for the past 3-4 years and they do the trick. We place two blocks in each bait station and we have the stations all around the perimeter of the house. We do this in late summer to start of winter for the mice and early spring to the end of the summer for the voles. Since using the blocks we have not had a problem with mice getting into the house or voles making trails in our lawn. The professionals use these blocks and now so do we!
