I heard something pretty clever last year from an old man who sold me some sweet corn (since I had none after the coons ate it all).. He said, use Cheyane Pepper. What you do is when the corn first start to tassel out, sprinkle a healthy dose on the silts. Coons will leave that alone and they won't be back. He said his daddy swore by it for over 50+years and now he does it.
My wife and I are members of Sam's Club so we bough some Cheyane Pepper in bulk and it's not too expensive.
Some people had their doubts about it- as did I. Thinking the corn would be smoking hot from the pepper and it's not at all. The only thing is, you want to make sure you wash your hands after shucking it b/c if you forget and rub your eyes or go to the bathroom... well, you know. It's gonna burn. But as for making the corn hot, not in the least bit.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
