I have had that problem for years and just trapped and “relocated” one yesterday. I keep a large cheap hot sauce in the garden shed and I put a few drops on the tip of most ears in the early silk stage and that seems to work and it hasn’t affected the taste of the corn. I even put a electric fence around the corn patch one year Thank you for the advise. I got the 'electric' fence installed. I am at the point where I want them 'fried' but this will only zap them.
I also am at the point where this corn is costing me more than it is literally worth no matter how good it tastes.
