@MiguelGuerreiro Can you provide a link to that evidence please? That would be great to look at.
I’ve been following a citizen science project by Prof. Dave Goulson’s Buzz Club here in the UK. It’s collecting useful information on bee hotels.
It is in its infancy. Bee hotels do attract mites but as to should you clean out your bed hotel, the jury is still out on it.
Their data suggests hotels that weren’t cleaned out have more occupied holes.

@MiguelGuerreiro I’ve seen some of those and mites are terrible for bee populations but I’ve not seen any year 2 onwards advice.
I’ll see how the bee hotels are in early spring next year. I can and will certainly clean them if need be. Or provide new ones.
I am conscious the time to clean holes is quite tight between new bees leaving the nests and new ones being filled.
I’m hoping better guidance can be provided based on practical evidence provided by such as the buzz club and Dave Goulson.
@MiguelGuerreiro I’m not sure how much relevance US or UK mason bee knowledge is to each other. I just use UK sources to be sure it’s relevant for what I do
I’ve seen US YouTubers using paper fillers and removing cocoons for storing. It’s interesting but that’s not something I want to do.
There’s good information in the lifecycle of UK mason bees in this link.

I’m interested to see if the holes the bees don’t use this year will be used by them next year & vice versa.
