I don't think I mentioned it here, but we
finally got rid of the yellow jackets at my place.
Late July we had a half dozen of them flying around in the finished side of our basement. Went outside and saw where they were coming and going from a spot under the siding above our walkout door. We have the Orkin bi-monthly prevention service with the unlimited between service callbacks, and my normal Orkin lady was able to come within a few hours. She sprayed a bunch of instant kill up there and said that should do it. Activity slowed but after roughly a week they were back in the basement.
Called Orkin back out and got my previous technician that I liked a lot. I hadn't seen Jamie in over a year, but apparently he was on workman's comp after training a new tech on an alternative method of dealing with paper wasps and ending up getting the crap stung out of himself and falling off a roof. Messed up a tendon in his leg. He was still unable to run but hobbled right up and fired a bunch of dust there, getting stung a half dozen times in the process. He advised me not to seal it up until activity ceased, because they can and will chew through wood/drywall etc and swarm in the house vs the relatively few stragglers we were dealing with.
Over the next week outdoor activity slowed to nothing, but we were still getting random one's in the basement. The dust insecticide sticks to the wasps and in theory they track it deep into the hive, getting it on internal workers and eventually the queen. It will also be stuck on the ones that get into the house which our dog and cat would gleefully hunt and kill. The dog however would eat them and the insecticide gave her the runs, which required a vet trip to a different vet because ours was out of town. $400 between the bill and lost wages as my wife didn't want to go by herself.
We get back and Jamie was there totally unprompted checking on things, which is why I liked him so much. Explained the dog situation and we went out back and looked under the siding and there was 3 perfectly round holes drilled into the house under the siding. This entire house is covered in random holes because the previous owners would switch TV/internet providers every 2 years for the promo rates and get new installations every time. We started pounding on the siding to see if any would fly out and sure enough they started swarming out of a different spot we didn't notice previously. Since they were already angry at us for banging the siding, Jamie ended up getting the crap stung out of himself when dusting up there. Dudes a legend.
I sealed it up a week later after we hadn't seen any of them in the basement for a few days with some spray foam that has that dust mixed in with it. I only got stung once in the ordeal after missing one with a fly swatter in the house, but I still get jumpy every time a fly buzzes. Tiniest things can really ruin your life for a hot minute.
Found this handy chart that aptly explains our yellow stripey friends.
Edit: Shortly after posting this I heard a "tink" from the light fixture right next to me. I'm pretty sure it was just adjusting from the heat of the bulb but I just about broke the keyboard tray on my desk jumping so hard. Sounded like a yellow jacket bouncing off the fixture. It's gonna be a while before we're truly comfortable down here again.
