My son lives in Bakersfield and his house had a big wild bee hive in the attic when he moved in. He called a local bee keeper organization and one of the members came out and got the hive, queen and all. He said he was grateful to get it as the wild bees were very hardy and disease resistant. With colony collapse a problem having a wild strain to introduce into a domestic strain adds strength to the hives. It was a win/win for all involved.
