New Season = New House?
No! Your existing house will work for both Mason and Leafcutter bees. You just need to upgrade the nesting materials. The video below will guide you.
About those materials . . .
You can order your nesting materials separately and choose the 8mm size nesting holes for your Mason bees or the 6mm size for your Leafcutter bees. Or, you can simply order the DIY Upgrade Kit and choose one of the summer options. The kit even includes the bees!
