I have an observation hive in my house (two of them actually), and occasionally they tend to get loose. It happens. But the wife and the dog don't really appreciate it too much if they get out.
So I usually use this to capture the little guys: http://www.walmart.com/catalog/produ...ct_id=10098012 It doesn't hurt them at all. They get caught up inside and then I can dump them back into the hive when I open it up, or just let them free outside.
Just a thought, didn't know if anyone else had done this before.
