I haven't seen my successful method mentioned yet, so I’ll share. I had a ground nest, but it was built into a rock wall for a raised flower bed. They had several exit points. Despite emptying multiple of those spray cans, it was a healthy hive. Feeling discouraged, I dumped a bunch of fire ant powder all over the rocks. I did it at night, hoping they were all in there. I checked on them the next day and they were gone. I have no idea if it killed them or they decided it wasn’t a good home location anymore and left. Either way, no more yellow jackets.
