There's a great old mousetrap design that works really well for mice, maybe ideal for shrews and voles as well since they're the tunnel type rodent...
Mousetrap reviews by Shawn Woods on youtube are amazing. He has an endless supply of rodents on his farm and yes, we get to see the traps tested.
So here is a video where he tests a 3D printed version of the old Mascall trap in the barn. The rodent goes into the hole to get bait and wham. One after another until it's full up.

And here is one where he shows step by step how to build a NINE hole Mascall, so you can catch nine in a night.
