Available now -Native Phragmites common reed grass tubes for the culture of Mason Bees (in packets of 30 for $15.00), harvested sustainably from my farm in Metchosin . They are the most efficient type of tube for attracting mason bees and for reducing parasite infection. For evidence see: ( See https://masonbeesforsale.com/choosing-nesting-materials/ ) If you don't have mason bees to release, just put out the tubes and the wild bees may fill them with cocoons for next year. Leaf cutter bees will also be attracted to them . I also can demonstrate how you can make your own bee houses at no cost out of simple re-purposed and recycled materials. see http://www.gfletcher.ca/?cat=2 If you are outside of the Victoria area information on the website on how to order the tubes -$15.00 US or 30 tubes (includes shipping.) if you can't pick these up at the farm. I would prefer not to send cocoons in the mail. However, if I receive enough orders from the Cowichan area I will consider a delivery.
