One year every single black walnut tree in my neighborhood was infested with webworms. I drove miles down the road and those trees were entirely white from the webs. There was virtually no walnut harvest that year. The trees bounced back and the next year i guess nature sorted it out.
If you have other fruit trees, the webworms can spread to those too. So act fast since cultivated trees aren't as resilient as wild trees.
