My tremendous fear of stinging insects was rekindled today... while mowing, I noticed this. Located about 3' from the garage door, which I keep open when working. I saw 2 in the garage yesterday while working on something, then realized why today. There were about 40, and I assume they were working on building a nest. Had to get a buddy to come spray em for me. I was real close to a full blown panic attack. One childhood incident ruined me for life.
Hornets?
