I have had mice get in my house a few times.
I hate glue traps. I had seen them used at a restaurant I used to work at, and it is pretty awful. They get stuck and panic and nearly (sometimes actually) rip themselves apart trying to escape.
But they're the only things I've seen that work. Because of what I saw with glue traps, I tried all sorts of "instant kill" traps. Some of them worked at first, but the mice quickly learned how to get the bait without setting off the trap, or they learned to set off the trap without getting caught. (No idea how - in some of these I'd have thought it'd be impossible.)
So I got some glue traps. They worked and they worked fast, and they got them all, both times this happened. You usually hear when they get caught, so I would get the trap, drown them, and dispose of it. It's pretty awful, but I'm sorry, I can't live with mice in my house.
My only real alternative is to get a cat, and trust me, having grown up with cats that ate mice and birds, they're not much more merciful.
> Winnipeg veterinarian Dr. Jonas Watson agrees with the group's position, pointing out that glue traps are also entirely indiscriminate, often trapping other animals as well.
This is a feature, not a bug. These traps are almost always placed inside, and whatever else is getting trapped is also a pest.
