Q.I have web worms on an ornamental cherry tree. How do I get rid of them in the fall?

This is a new home for me, but evidently the previous owner also had issues with web worm on this tree. I know it is too late to use any treatments that are designed for spring. What is the best for now in late summer/early fall?

If you can hit the web with a strong enough water spray to break the webs, the birds will get them.
Apparently there is no way around having to break open the webs. A treatment of neem oil would be fine at this time of year, as well as in the spring. There are quite a few natural predators for these guys, so once they're exposed, the problem may resolve itself.

If these aren't sufficient, you may want to contact your local extension service for more information.
