Big bees use beg holes.
These big natural reeds come in varied sizes (7-10mm dia.), and in general are bigger than the small natural reeds (4-7mm dia.).
Also available as quantity of 50.
Crown Bees has obtained quality natural lake bed reeds. Reeds are hand cut to length with hole sizes around 5/16" (8mm) and are approximately 6" long, fitting into all Crown Bee Solitary Bee Homes. Each reed has a natural node to seal the back end preventing predator access.
In a side-by-side comparison, a nesting native bee prefers natural reeds over tubes or wood trays. We believe this may be due to the variety of hole sizes helping the female native bee to quickly and easily find her hole.
These reeds are perfect for spring mason bees and other medium and large solitary bees and beneficial wasps!
