Working in the woods for my career, I found that yellowjackets like to have a 180 degree defense perimeter, so the nests are located at bases of trees, bushes. And they have guards, roaming around, looking for guys like you, to nail...!
Look for any activity, then steer away...!
The crazy part was, there weren't any guards standing watch to give me a warning. Turned over a rather large plug, nest and all, and I was swarmed before I knew what hit me.
Must have been in early morning, eh?
Yes, there would have been some activity, right at ground level.
Then, there would be several at entrance to the nest , to continue insulating everyone,
long enough for everyone to have their First Cuppa Coffee..!!
So, if you study and see a sunny opening, that has NO Activity - go there instead...!
Thanks Truth! I didn't get your message. The injection helped a lot.
I?m happy to hear that buddy I really am. Was it from a nest or underground?
Problem with yellowjackets is they release an attack pheromone that sets off other Yellowjacket nests in the surrounding area. I found out first hand when I ran my push mower too close to a ground nest. I was picking them out of my socks and britches an hour later (gives you an idea of how long ?the battle? lasted).. That was about 15 years ago and ever since then I carefully survey the lawn for the little *******s before raising Cain with the lawnmower on Sunday mornings. Doc said I was very fortunate I wasn?t allergic - the number of stings (easily 100+ just from the dead wasps I picked up from inside my house and clothing alone) could have cause anaphylaxis and recommended I come back in 6 weeks for an allergy test. I never did - but I did get stung again a few years ago by paper wasps that had nested in a compost pile and I was fine. Your photos show a lot of swelling and that?s concerning. Stay safe out there !
