We get mice and voles in our studio this time every year. We store wool, fabric, leather, art materials and a whole lot more there; we can't afford for it to be destroyed. Despite my best efforts of sealing the building up it's still a planked, insulated, barn - they're going to get in. So, sadly, I have to put traps down. I think, about 80% of the catch is yellow-necked mice and field voles.
I've tried the ultrasonic deterrents with zero effect.
I would not dream of using any poisons because a) it's a horrible way to die and b) I cannot guarantee it won't get passed on to predators.
