Fall Webworms Management and Treatment
In addition to their silky nests, webworms can cause severe leaf damage on your trees. You have a couple of options to control and remove fall webworms. Learn all about webworms here.
You can prune off the nests and destroy them. Or, you can have Davey treat the tree with an insecticide when the insects are vulnerable.
