It seems just nuts, but that’s the whole point. My father-in-law has two pecan trees in his yard. He wants to get the nuts from the trees,but the squirrels think they own the nuts. The one that wins will be the one that gets to the nuts first. The key to keeping the squirrels from the nuts is keeping them out of the trees!
For the last few years they have been winning the war and getting lots of pecans.
