Mice are unwelcome sights in most homes, but some homeowners would still rather not kill the rodents. To create a simple, humane trap in which you can catch and then release mice, save a 2-liter Coke or other soda bottle from the recycle bin. However, it is important to remember that mice released close to the home may find their way back inside.
Cut the top off a 2-liter Coke bottle and set the top to the side.
Fill the bottom of the bottle with aquarium or outdoor gravel. The gravel acts as a weight and prevents the trap from toppling over once the mouse in inside, according to the Planet Green website.
Turn the top upside down so that the bottle's spout faces down and resembles a funnel.
Add several spoonfuls of peanut butter, cheese or other food to the base of the bottle on top of the gravel.
Set the upside-down funnel into the open end of the bottle. Be sure to remove the cap.
Use packing tape or duct tape to tape the edges of the "funnel" and the bottle bottom together. This seals up any loose edges and secures the funnel piece in place.
Dip a paper towel in olive oil and rub it onto the funnel. This makes it harder for a mouse to get traction, making it more likely that it falls into the hole while trying to get to the food.
Place the trap in an area where you commonly observe the mouse or mice.
Stack a series of books on top of one another to form a "staircase" to the top of the bottle. This helps a mouse get into the bottle.
