Do you your pecans have holes?

When pecans fall from the tree and have holes in them, the pecan weevil has gotten into them – sometimes most of the crop can be bad. The fruit will look decomposed or rotted if you break the shell open. The weevils lay their eggs in the soil under the tree, hatch in early August, and continue to make their way to the nuts on the tree through August, September, and even into early October. Peak emergence is from August 10 to September 20. They climb the tree and infect the fruit. It will usually occur under the same tree each year. The traditional way to monitor them is to place small cone shaped cups in the ground under the tree with the tops level with the ground. When the weevils migrate to the tree, they travel across the ground and fall into the cups. To treat, spray the ground and the trunk up to the first limbs with a good insecticide such as Seven. Apply it three times, ten days apart, starting when the weevils first appear.
