Jeff...No answer for you--just a question. Are you planning to shoot or trap the squirrels in your back yard? I ask this since you mentioned that they're prolific, yet asked if "...any squirrel hunters out there..." have a recipe. This gives the impression you aren't one of the aforesaid squirrel hunters. Sounds as though you're going to bag one of these rodents (yes, they're rodents, not mammals) outside your back door!
The squirrels in my own yard drive my dog crazy running across the back fence and leaping from tree limb to tree limb, but her hysterical barking soon drives them into my neighbors' trees. I'm afraid I'll have a hard time looking at a squirrel for a while without seeing it stretched across a plate in my mind!
Sorry for being facetious when you are (or may be) serious with your question, but I couldn't resist!
