Hi
‘Original’
I’ve had a problem with bees released returning to my nest tubes. Attached are two photos of my boxes. I released about 20 in the setup named “original” and only one bee nested there. I’m going to try the setup named “latest” and was wondering if you think either or both should work? Thanks Norman Z



‘Latest’



Hi Norman,  These are beautifuly constructed homes for mason bees.  Both should work.  At some locations there are lots of nesting places for mason bees such as cedar shingles and often mason bees use these over the ones we set up.  The only way that I know to get them to use your nests is over a year or two, increase the number of mason bees that are produced.  I noticed that the ‘Latest’ home is set on a post.  This works fine, but in cool springs, this location would be a lot colder than a site like on a wall and be a lot less attractive than the home on a warm East facing wall.   All these facts make an impact on successful nesting of mason bees.  Sometimes it is difficult to figure out why the population is not building up and it could be as simple as a few bird predators.  Try different locations and homes and slowly build up their numbers.-Margriet
