A question from Michael in Oregon.
If I need to set out more nesting sites for the Mason bees should I put them next to existing sites, or, put them a bit away from the one’s I originally set out?
The reason I ask is that I am get many more bees to nest so far this spring compared to last year but I do not want to mess up the bees visual cues to the old sites. I also know they like to be near each other. Your thoughts?
I don’t have the exact answer, but I think you are on the right track. Perhaps in visual range and clustered nearby would be a good solution. -Margriet
