Cedar Glen Bees gets their packages from suppliers in northern California but they have the ability (new this year) to repackage the packages into cardboard boxes with vents over the actual package of bees. This allows them to ship anywhere you can get USPS, UPS, or FedEx. The packages are double packaged, once in the wood and screen package and again in the vented cardboard.
They've shipped bees that way to vermmy35 in Chicago, Il this year. So Idaho is a short hop and I know they are getting more bees to ship out soon so you may still get some there.
Call 360-652-8967. Thanks to the reputation that slaphead told them I had, if you mentiion my name you'll get excellent service.
