HI pepito54 I don't know much about mason bees but went looking for information for you.
According to this site cedar is fine. http://www.crownbees.com/choos...
This site tells how to make a mason bee house and for your size wood recommends 5/16 of an inch drill bit for mason bees. It says drill the holes 3 1/2 inches deep. http://www.nwf.org/How-to-Help...
