Autumn Blaze maple here. Mine is a rather long story, I started getting stung, and was yelling, and my neighbor who was a nurse was asleep in her car, and my yelling woke her up. She helped me in the house, got my dog in the house, got my epipen and did it, then she called 911.
I couldn't get any pest control service out for a couple days, so my two neighbors backed a truck up under the thing with a trash bag, cut the limb off into the bag and tied it up real quick. They thought it was cool they did that, I thought they were really stupid. The pest control said there were probably about 300-1000 wasps living in that thing. Also, after two days, there was a new nest being constructed in the same tree from the "free" wasps, that the pest control had to deal with.
