Couple of thoughts. Likely seasonal so you may only have weeks or a month to order mason bees for this year.
Not sure if mason bees are guilty, but some 'mud daubing' bee or wasp species will fill every possible hole they can with mud which then dries. Not cool if it is the over pressure vent for your water heater! Or more recently the tip end of my propane torch. Could not clean it well enough and had to buy a new one... Nice having a push button start, but was not planing on buying a new one. Most of it was over 40 years old and had been my dads
More amusing was a hose repair coupling. Daughter needed one and it took me several minutes to get it off the nail it was hanging on. Yup, packed with dried mud.
