Beavers seam to like 10 inch maples. First they flood me out then they have at it. They seam to know when I am away. I hope I have seen the last of this for a while. I taped 10 trees at the waters edg and used three foot drops to buckets and the darn beavers whent back to the birch. One of these days Allice pow right in the kisser. Ya it ran sort of but this anint what I am looking for. I didnt test it I boild it and made a quart of prity good stuff.
