I had been taking care of the squirrels via .22 Marlin but with many new folks here at the lake, I put the rifle away. The wire will have to do.
We used to use the .22 on squirrels but we really dented the population with a 10 gallon bucket 1/3 filled with water and whole striped sunflower seeds floating on top as a layer. We got dozens in one summer. Early on a raccoon dumped the bucket but we put a heavy iron grate on top. Holes big enough for the squirrels and chipmunks to go through easily.
