That's when I hit my yellow jacket nest also at dusk. If it was earlier int he day i would have seen them coming in and out of their nest. Beause it was at dusk they were all tucked in for the night and then gave me quite the surprise.
Doesn't look like a yellow jacket nest to me. They look similar but are either IN the ground or IN something else like a bail of hay. Been stung 6 times this year and about 30 last year. Both times from running over the nest with a lawnmower. My typical way to handle them is to pour gasoline down the hole and smile as I light a match
When I was a stupid kid and didn't know any better I found a Yellow Jacket nest in my Grandmother's back yard. I got a Bad-mitten racket and started whacking them as they flew out of the ground hole. I was doing a great job and knocked the bajeebees out of every one that flew out (smiling from ear to ear). What I haden't counted on were the ones coming back to the nest that knocked the bajeebees out of me. Man the thought still smarts!
I work at a lawncare company and we never run into ground bees on properties we care for. The explanation is that our chemical apps keep them away.
Seems to make sense. I have a decent sized yard and I fert and apply spotspray for broadleaf. Never had bees. The parents house had them when growing up and they never treated it.
