I have sold all the available bumble bee colonies for this spring. Shipping will begin in May. For those who are interested in rearing their own bumble bee colonies, I can provide a copy of the book "Befriending Bumble Bees" from the U of M for $18.95 + $1.75 for postage. This book will tell you what you need to know to rear your own. Email for your copy. bees@mysite.com
