Be sure to follow the rule before you head out.
Rule: You must post before you leave.
In my village in the Netherlands bat roosts are installed in a bunch of places, they also mandate that houses have little box things on their side for them. Never seen a single bat lmao, but in the old family house in France there's a bunch in the attic.
