I've only come across one buried nests since I've been at my house but every year, I get nests under the eaves. I usually do a weekly check now so I can knock them down before they get too big.
That happened to me, I had a long sleeve shirt and on and they were up my arms, I never ran so fast into the house, my arms had several stings. I waited until nighttime, and I sprayed the hole.
It'll take a long time to break even. I just had to install a new heating/cooling system and between the savings on efficiency and the rebate we're doing ok.
Went to an Aerosmith concert in the 80's in Worcester. After a few songs Steven Tyler collapsed, probably from drugs or booze or both, end of concert. A lot of people complained but we got bupkis.
