Ugh. I hate rodents now. Used to like them and think they were cute until I lived in a very bad apartment building.
Do not get glue traps. They just get stuck and scream and drag it around. Don't read up on it and drop snap traps in a bucket of water...the stench in unbearable and you will not want it near you, or ever use the bucket again either. Poison works, but they may die in the space and stink it up, or a pet may get the poison.
Cats are the most humane answer, if looking for humane. If you don't like cats and prefer dogs, rat terriers keep them away. Had a neighbor with 2 of those cute little dogs, when the dogs moved (the neighbor moved too, lol) the rats came back. Wish I was not allergic to pets now.
Wonder if you can store soap in an aluminum trash can? Wrap it up and put it in, put more wrap over the top then the lid? Hard to get out though I bet.
I too would be lured by Nutella, your mice are living good for those last few nibbles!
