How can one humanely kill a mouse that is caught in a glue trap?

One humane method to euthanize a mouse caught in a glue trap is by using a CO2 chamber. This involves placing the trap with the mouse inside in a sealed container and introducing carbon dioxide gas to induce unconsciousness and ultimately death. Another method is to use a non-toxic oil, such as vegetable oil, to gently dissolve the glue and free the mouse before releasing it outdoors. It's important to handle the situation with care and compassion to minimize suffering.
