to bee honest, I would bee careful about the "guaranteed" live removal thing too.
Sad to say, but out of the many removals I have done, there have been a couple where the bees got themselves into a place they could not bee gotten out of and the remaining bees had to bee "put to sleep" so the job of making the client's house bee free could bee finished.
It does happen. hopefully it;s a rare thing.
if you do have or get a LinkdIn and/or Facebook page, look me up. we can talk bee stuff.
