I am thinking about putting up a bee “hotel” in my yard. (Such as https://smile.amazon.com/s?k=mason+bee+houses+for+the+garden&crid=24ZY8HJDDYWC9&sprefix=Mason+bee%2Caps%2C227&ref=nb_sb_ss_ts-doa-p_6_9) . those are cute, but I’ve seen much larger ones.
But, I wondered first if bee-knowledgeable people think they are effective or useful? ?They seem like a good idea, and I’ve see cute ones from time-to-time. But the ones I’ve seen were unoccupied.
So, I wondered if having the tubes so close together was not so good or attractive for the mason bees?
Do the bee houses perhaps promote disease or possibly not serve territorial needs?
What can you tell me about Mason Bee houses?
