Try diazanon or malathion, fixes that problem.
I'm not really sure of a fool proof method, but there are sprays you can get. They are tent caterpillars. They usually affect fruit trees, especially cherry and a few years ago Seattle did some heavy spraying trying to get rid of them. It helped for a couple years, but now they are back in full force. I had them in my apple tree at the beginning of spring, a little spray right on the nest and they died.
I can't even sit in my yard they are every where we have a crab apple tree there was a nest , but it was to high to cut. what do I do? I want to be able to sit in my yard
i seem to have sort of the same problem..but the tree is not in my yard...it belongs to the nieghbor but the caterpillars are all over my yard...anyone know what i should do about this?
About those Caterpillers,,,We had this problem a few years back and I sprayed the nests with Vinegar. This killed the little ones and it was not un safe for the trees. Use it full strength in a spray bottle. I hope this works for you.
