I think the idea is to keep it charged so that it does its work on

Does it really need an arduino, or just a wired power supply and a way
of forcing all entering and exiting wasps of touching the charged wires?

I've seen one of those at a friend's cottage. It is only $10, so it
might be worth just buying one to find out how it works and adapt it for
automatic use with your wasp nest. We had one in the floor of our
balcony. It was a nuisance...
You might want to adapt it with very fine wires brushing around the hole
(but if the wire is too fine, it might fuse instead of delivering the
intended shock to an insect...)
