just thought I would share this. Getting overrun by all variants of hornet and wasp. put out my usual traps which have a top and bottom chamber; one with scented water and the other with a lure. But the store ran out of the replacement lures so I got two other traps. One was a sealed bag that you gut a hole at the top, add water, and hang. those are doing ok. This one was one I wasn't sure about but evidently works. Just a pattern with sticky fly paper on it.
There have hundreds of dead in them after a few days
