In this Home & Garden video tutorial you will learn how to identify pecan weevil problems. John White presents this video along with Carol Sutherland, extension entomologist. After pecan is infected with pecan weevil, it has the potential of spreading in the entire area. The indication of pecan weevil infection is an opening on the crust of the pecan which may or may not be a perfect circle. But, on the nuts the holes are perfect circles. There is usually one hole on the nuts; though sometimes there can be two. This is the indication of this problem. On the contrary, a bird peck is a larger hole and with the surface depressed due to the impact.
