At least in North America, the "colony collapse" stuff was a livestock phenomenon more than it was a wildlife/ecology issue. Honey bees aren't native to the US; if you see a honey bee in your back yard, there's a pretty good chance that somebody owns it.
This is true even in Europe. If memory serves the percentage of "wild" honeybees (feral may be a more fitting adjective) is in the order of 1%.
At any rate, in warm areas of the US there are many feral old world bees.
Recently I saw a talk where the speaker said that if you find any africanized beehives in the wild, you should kill the hive because you don't want the africanized bees to spread. (Or if you have an africanized beehive, re-queen it.) I don't have any, and I'd be loathe to kill bees because I'm quite fond of them, but it's probably good advice.
But also if you're going to try to kill an africanized wild beehive you should use soapy water, with a sprayer, and if the bees attack then you'll spray your attackers with soapy water than that's that.
Every time I get a decent population we get some cold weather and I don't see them again for a long time.
If anyone has issues with them boring into buildings, there’s an easy solution: stuff a paper bag with some plastic bags and hang it up nearby. The bees will think it’s a wasp’s nest and vacate the area within a few days. I know someone who does this every year and it works like a charm. Which, I suppose in a way, it is.
