What happens is the original hive gets crowded. The queen takes half of the hive and leaves. They hang out in a tree or bush in a ball about the size of a football. They start sending out scouts to find a new place to live. Generally they find the place and leave between 3-5 pm the next day. They like to find a space that in enclosed and is easily defended. This guy found out his cabinet was the perfect place for them. They had moved in 2 days prior, and had a good amount of comb by the time he noticed them. We got them out of the cabinet and into a nuc, and took them home.
