Fall webworm nests are appearing in pecan and oak trees throughout San Antonio this month, usually as silky webbing wrapped around the ends of branches.
The nests look alarming but rarely kill a healthy tree outright, though a heavy infestation can strip enough foliage to add stress a tree doesn't need. Trees that are young, newly planted, or already stressed from summer heat can lose enough leaf coverage to set them back going into the cooler months.
Texas Tree Authority inspects affected trees to determine whether the infestation needs treatment or simple pruning to remove the nests, and most cases are resolved without any spraying at all. Catching it early keeps the damage from spreading to healthy branches nearby.
If you've spotted webbing in your pecan or oak trees, now is the time to have it checked before the caterpillars finish feeding for the season and move on to new branches nearby.
