A few years ago, we had a bald-face hornet nest that formed on an upstairs bedroom window. It was fascinating watching the inner workings of the nest. A tap on the glass would cause the nest to unload, and those females would fly into the glass repeatedly, trying to get the offender...
I was going to eradicate them, having remembered being hammered by them in the leg a few years before. But as I got to reading on them, I discovered how beneficial they are; and it did seem we had less bothersome bugs that year. So we had a truce that summer. I kept a close eye on them when I was working in the
yard, and made sure my family knew where they were. But everyone made it thru the summer without incident.
As fall drew near, there was less and less activity, until one day I saw a single hornet emerge and fly away; I think it was the queen. The rest were dead or gone. I scraped the nest off the window, cut it in half, and let my daughter take it to school
The next year, we had another nest up, in a tree this time. Again, no incidents.
Yellowjackets, on the other hand, have been a problem, especially at the
compost pile. I've learned to bury any
fruit under a layer of
wood ash, or there's a chance I'm gonna get hit the next time I'm out there. They're just plain ornery!
