Quick and dirty badger deterent

So if I had this ‘High Voltage Transformer Generator DC 3V-6V to 400kV’ (https://www.amazon.co.uk/gp/product/B01MXV64IY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) with a 4x1.5v AA battery pack and 2 thin (0.5mm?) parallel (open circuit) copper wires say 3m long would it give a badgers nose a buzz and stop it going under my shed?!! Cheers

I would say yes.
I once researched this approach for controlling mice and there were many DIY mousetrap YT videos using that part.
