Oh no! That sounds like a huge ordeal! I hope you got rid of the bees. I haven’t seen any sign of the bees under my barn yet this year so I’m hoping that the mice that were running around there all winter ate the bee larvae. But your post gave me an idea and I stuffed one of those fake wasp nests down between the kick boards and the wall close to where the nest was. Those fake hives cleared wasps out of the rafters in my barn so it’s worth a try to see if they’ll stop new bees from setting up close by at ground level.
It was super neat to open up the nest and see the honey pots and larvae! The entire outside was constructed of horse hair, hay, bits of gauze 4x4, and what seems to be bits of fleece saddle pad (gee, thanks bees). I hate that I couldn’t relocate them. Why do bees pick the worst possible places for hives?!?
I was out mowing on our zero turn last year and all of a sudden having excruciating, burning pain on various body parts and realized something was getting me. Boy you never forget that. Since then I’m always on the look out. They had a nest under a tree root that was out of the ground. Later, something got them all - probably a skunk.
