Don’t bother with glue traps if you’re looking to be humane. It’s a horrific way to go, often involving limbs desperately chewed or ripped off in addition to creating warier mice. Poison is terrible but the most effective method. Creating a rat trap bucket is far and away the most humane method but is very, very hit or miss. A beautiful bandaid for managing a population without destroying it, or a means of saving as many animals as possible before purging those that remain. Just my experiences.
