We had a bit of a maouse problem in our attic last year…. could hear them at night.
Tried normal “snap traps” – the mouses seemed to just remove the bait.
tried humane “tilt traps” and found a mouse dragging it across the attic floor…
so I resulted to a Bucket half full of water, length of wood for the mouse to crawl up – baited with little blobs of chocolate spread, coke bottle (both ends removed) taped underneath half way up on the end (to make a see-saw type tube….
Blob of chocolate spread on the far end of the “Tunnel”
Mr mouse walks up wood… walks into tunnel… tunnel “over balances, and tips mouse into water – mouse gone.
I got 9 mice like this in 2 nights (multiple buckets)
…they’ve not been back since.
