This year I have about 200 corn plants all looking awesome no bugs perfect. All at the same time squirells destroyed all of it in three days, the first day I thought it was racoons but the next day when I came home for lunch, one ran right across the street with a cob in his mouth then the next day the crows helped them finish and it was all over, every piece gone or eaten. Every year insects get me but this year the critters did it. Wait till next year
