@PatrickoftheG If you can, grab it by the head with one hand, pull by the hind legs. This will severe the spinal cord and lead to a quick death. This is how my father killed his lab rodents. And yes, it would be great to live in a better world.
Right now we use live traps and release the mice near thick piles of branches, hoping some of them will survive. Or at least they'll feed our owls.
@PatrickoftheG I understand your circumstances and, like you said, it would be great to live in a better world. I'll check with my friends who still kill rodents to find out what they believe to be the most humane way.
@szescstopni I wonder if I could get some thick gloves to prevent bites and scratches, if that would not make more sense and be better for them.
I favoured live traps when I lived somewhere I could release them. I am so urban right now that it would be basically putting them on the street to run back into someone's home.
Also, half of the year I am pretty sure I would be just killing them via cold given my geography and the fact the ground is frozen a meter deep.
Thanks for the response.
