Referred to by many as bag worms, tent worms or web worms, these pests can set up camp in your pecan tree in no time at all. The web is the protective area for the young that have not hatched yet. Once out of the web, these little guys will eat away at the foliage of your tree and take on the pecans themselves. They generally won't harm the tree to the point of endangering its life; however, they do kill leaves and wreck havoc on your harvest. For this reason, it is best to remove them as soon as you see them setting up.

Spray the webs with a water hose that has some pressure to it. Knocking the webs out of the tree will remove them fairly quickly and kill the little ones.

Trim out the webs using tree trimmers. The goal is not to cut out entire limbs, but to just snip the web as close to the limb as possible where it is attached to the tree. Put all the webbing together in a pile and burn it to kill the worms and keep them from reinfesting an area.

Spray the tree with an insecticide if you are too late and the worms have already hatched or to kill the adult moths that are trying to start laying their eggs. You will need to use a sprayer that can reach up into the tree or use a ladder to get closer to the issue.

Treat Pecan Trees That Have Worms In The Nuts

Cut a strip of tree banding material at least 3 inches wide and as long as the circumference of your pecan tree. Place the ladder by the tree. Climb up so you're at least eight feet above the ground. Dip the spatula into the Tree Tanglefoot. Smear it on the banding material until the entire band is covered. Repeat the application once every week for six weeks, beginning on the first of August.
