Using the drill, you drill different sized holes between 2 and 9 millimeters wide into the wood. The holes should be as deep as possible. It is important to note, however, that the wood is not pierced.
Now take the emery paper, wrap it around a pin and go inside the holes so that no protruding wood fibers can hurt the bees.
The bees like sunny and sheltered places. Be sure to attach the new home so that it does not bob around even in windy conditions. Once you’ve found a suitable place, you can either hang up or put down the insect hotel. For example, house walls are ideal.
