I had about 14 hives at one time...many, many years ago. My only concerns for MSD was her location and I wasn't sure how far the Africanized bees may have penetrated her area.
Swarms, as a general rule, are very docile and extremely easy to handle. Add to that, bees have taken it on the chin for the past couple of decades with diseases and mites. It's rare to find a swarm nowadays. Given the proper care, this swarm should serve MSD well for years to come. I got calls all of the time to capture swarms. I just gave my name and number to local law enforcement and they'd be Johnny-Quick to call me when the received a complaint.
Bees are cool little creatures. I used to spend hours upon end making all of the hive equipment myself. It was a great way to quietly pass the time.
