something wrong with ash tree
I live in South Texas near the coast and moved into a house with an ash tree.
It is covered on one of the main branches with fine webs. The webs are only around the branch and are not tent worms. When you scrape away the webs there are hundreds of tiny flea sized bugs underneath. The leaves are spotted with yellow and black dots. I have sprayed with a wide spectrum insecticide but they have come back this year. Any help would be appreciated.
