How to choose the number of nesting holes you need
How many nesting holes do I need?
Each female solitary bee needs a nesting hole to claim as her own. A female solitary bee will nest elsewhere if she can't find an available nesting hole.
For Spring Mason Bees: We recommend 1 nesting hole (8mm size) per 1 mason bee cocoon. Check on the capacity of your bee house while mason bees are nesting and add new nesting holes when you see 4 out of 10 nesting holes capped.
For Summer Leafcutter Bees: We recommend 1 nesting holes (6mm size) per 2 leafcutter bee cocoon. Leafcutter bees naturally have a higher dispersal rate than mason bees and this is why we offer more cocoons per leafcutter bee order.
