If you notice Woodpeckers or other birds attacking the
tunnels looking for bee larvae, fix a piece of chicken wire
across the front of the bee house. This does not seem to
deter the bees.
Basically, make sure that a four inch beak (over estimate, three might be OK) can penetrate a hole in the "hotel."
I suggest that chicken wire is an integral part and not optional.
Don’t disturb already fallen wood, of course — current weather conditions should certainly provide a surplus of newly fallen branches without having to find old ones.
It’s even more low-effort than a bee hotel and my log sanctuary has been home to hibernating admiral butterflies, hedgehogs, and many fungi and fauna that supply the bottom of the local food chain.
Also: stone piles can host a lot of animals as well.
My favorite is this hexagonal design, which can be easily taken apart, cleaned, and stored at the end of the season. I just printed it and placed it inside the cheap (ineffective) one from Costco
I use strips of printer paper to line the tubes.
