The best suggestions I have is to log onto Beesource and use the search box for mason bees. There are many threads there. Beesource is THE best bee forum on the web, with many of the world's best beekeepers participating. If you don't find what you need, sign-up and post a thread looking for the answers you need.
If you like the forum, add me as a friend ... my screenname is Dances With Bees.
If I haven’t responded to your comments yet, I will. Have to go outside and do several chores and will be back in a couple of hours. Thanks!
