This advice from PETA is a little transphobic
Make a DIY trap.
In a pinch, you can make a humane mouse trap by placing dry oatmeal and peanut butter (I guess mice and I share the same favorite snack) at the bottom of a wastebasket. Stack bricks or books along one side so that the rodent can climb up and jump into the basket—once the animal is inside, he or she won’t be able to get out. Captured mice can be kept calm by placing a towel over the trap.
