Hello everyone, and happy 2010! Last fall I removed the bee cocoons from their paper straws liners so they could be cleaned and sorted. I don't normally do that but our very wet spring resulted in some mold issues, so I wanted to be sure they were healthy.
I recommend a starter colony of (20) bees for a house that has 30 - 40 nesting holes, since not all bees will survive to emerge. I try to approximate the ratio that is found in nature, which is about 30% female and 70% male.
