All the pecan trees in our area are wrapped up with these webs. Can someone tell us what these worms turn into? Do you know how to get rid of them?

I live in North Carolina too and believe me I don't like these worms any more than you. I have had a great deal of success by spraying them with wasp and hornet killer.


They are too high for me to climb to get them and most of my neighbors cut the limbs and burn them. I just use the spay and haven't had any now for two years.

I live in Texas and have had the same problem with webworms. They will decrease the pecan crop on your trees. I have found the easiest solution is it to take a long pole, head out in the evening, and poke holes in the webbing. Then the birds can get in and will eat the worms and the web will disappear. My crop has increased greatly since. That is much easier for me than trying to spray them.

You need an insecticide that will kill the pests.
