It matters not to me what they do when the curtain is closed. I feel the same way about the small wasps that have constructed a camouflaged fortress-like hive in the vines near the roof. Even though fierce in appearance they don't seem disposed to acts of war and spend their day industriously flitting from flower to flower. That has to be of some horticultural benefit. I'm sure, prays the status quo will remain.
Scorpions are a different matter.
They are mean tempered. Distant cousins of the Bronx cucarachas no doubt. You have to draw the line somewhere. With the exception of the occasional scorpion execution, all is well in my insect kingdom until north of the border guests arrive. Thus far, none have shared my live and let live approach to cucarachas.
