What is the best treatment on a oak tree for web worms without damaging the lawn?
Harris County Texas
Oak trees don't get web worms so I think you may be referring to bark lice if the webbing is on the trunk. Check out this blog post from our Extension Office to verify:
If this is not it, them please attach some photos of the web areas from a distance and close up in sharp focus and I'll be happy to identify them.
