Some years ago, a swarm took up (temporary?) residence between the chimney and behind the interior wall of my house in SoCal. The bees were dropping down behind the baseboard and crawling out into the living room(!) A local bee removal expert and beekeeper was Johnny on the spot and took care of the problem. He showed up in shorts, T-shirt, & flip flops, and didn’t mind that he got stung a few times. An encyclopedia of bee knowledge, he said the kind that I had were a Russian variety and not Africanized, a relief.
We had a nest of honeybees under our shed some years back. They were pretty docile; I used to mow and weed-eat around there with no problems. Then one day my wife was out in the yard, not even near the shed, and got stung six times before she could get indoors. I got a canister of foam insecticide and did away with those bees. I suspect that an Africanized swarm took over the site at some point.
