I drove a lot of 3-4 cm deep different sized holes in a piece of firewood and put it to a dry and bee accessible place next to our house. Every hole got filled by next spring.
- Findecanor 5y agoI've been told the holes should be at least 5 cm deep, preferably 10-15 cm (4-6 inches). I've heard of insect hotels being raided by insect-feeding birds when the holes hadn't been deep enough.
- croo 5y agoWell I didn't do any scientific research about the project but it definitely works and the bees/hornets like it. We also have a lots of birds (20 or so different species) and no one attacked it so far. I guess I can try deeper holes on my next iteration :) it will depend on the firewood.
