Blue Orchard Bees, Pollination, & More...

Raintree Nursery
(raintreenursery.com 360-496-6400)

see explanation below

> We are reorganizing and have decided to temporarily curtail all direct sales except bulk bee orders (more than 100 bees*). Raintree Nursery, our major retailer, will carry our bees and nesting supplies. Please contact them for service. We will still supply them with blue orchard bees (mason bees) of the same quality.

> We are temporarily discontinuing the NB20 series (20-hole nest box, inserts) in exchange for the NB50 (50-hole, 6-inch system). This is our "Orchardist" box, with 5 times the capacity of the NB20. Raintree is offering this as a complete pollinator kit or separately with 100 extra inserts.

> These changes will enable us to concentrate on producing more quality bees. We guarantee our bees to be of proper size, parasite and disease-free, and at least 1/3 female. If you opt to obtain bees from another source, please read our RECOMMENDATIONS for purchasing bees from other vendors.

> We still offer advice on bees and pollination. Email, write, or call

*Once again we are sold out of bees for the coming spring. Please order now for spring of 2011! We will extend to you this year's price.


Thank you for your business -- may yours thrive!

Female Mason BeeMason Bees

Mason bees, also known as Blue Orchard Bees, or BOBs, are native North American bees. Like all bees they visit flowers for nectar and pollen and in so doing pollinate or fertilize the flowers. BOBs are very efficient compared to honey bees. They are reluctant to sting, are educational, and can be easily cultivated. If you are looking for fruit or berry pollination, BOBs could be a solution for you. Learn more about BOBs. Read about our bee products.

Orchardist Nest BoxSupplies for BOB culture

BOBs are solitary. Females build nests in tubular holes about 5/16 in. (6.5-7 mm) in diameter. They can be found nesting in many human-made materials and it is easy to attract them to artificial nest boxes with many holes. Years of scientific research have shown how to get maximum BOB nesting. Nest boxes should be lined with removable inserts which are replaced each year so the bees always have clean nests. Read more about BOB cultivation with the straw insert system.
