I cleared the area very neatly as I wanted make sure I had a clear understanding of the scope of the problem. In this wider shot you can see I've uncovered the top of the nest. The whole thing was about the size of a large cantaloupe.
When I went to try to pry it out intact, I wound up tipping the axis of the core with the four horizontal disks of hive inside the paper skin. This was unintentional, but very revealing. There are (barely still) living yellowjackets in this shot, having spent a second can of chemical warfare, but they're subdued.
So I took the opportunity to kick'em while they were down. What? I'm not paying me to bring these bombs back home! This final strike made a very wet soggy mess of the whole/hole affair.
Plus, as you can see here in the distance, I'd staged more cans of poison along my escape route should I need to beat a hasty retreat. Hopefully I wouldn't trip on the rake on my way out.
