I do not know about good or bad but hedgehogs love sprats - yes SPRATS.

I was pike fishing using sprats one warm February afternoon a few years ago
and heard a rustling in the undergrowth behind me. The hedgehog rolled into
a ball when I turned round but ate the sprat I left near his/her head end -
you should have heard the chomping! Another sprat went the same way before
Tiggywinkle went back to bed!

P.S. That was the only bite I had but it made my day!
