Didn't know at first but after looking around you can see the damage on different species of plants and trees it appears the stink bugs transferred it to other plants after he sprayed
Not bugs at all had a guy that lives behind me sprayed so herbicide on some bushes where thousands of stink bug larvae were. Unfortunately it killed the bushes and not the bugs. I think the stink bugs transferred the poison to my plants and alot trees and shrubs around me. Look up glyphosate...
