Yes, two multi-storey deluxe houses built by one person in one shed in one day! (sort of)
Have an old fence post lying around? Don’t buy a bug house when you can build one yourself. The one on the left has some bamboo running through it. I used a size 7 drill bit which seems about right for a ladybird as well as a size 20 flat wood drill bit for the larger holes. They do need a roof of some sort and the holes should ideally slant upwards to also help stay dry. The main wood itself should be left unpainted/treated.
A rainy day project if ever there was one. Get it done now in time for the cold weather when bugs will really need it.
