How to Build a Humane Mouse Trap With a Coke Bottle

Mice are unwelcome sights in most homes, but they can be removed from the house without killing them in a conventional mousetrap. A humane trap helps you capture the mice so you can release them alive outdoors. However, it is important to remember that mice released close to the home may eventually find their way back indoors.

Step 1

Cut the top off a 2-liter Coke bottle and set the top aside. Cut below the tapered top end of the bottle.

Step 2

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 is inside.

Step 3

Add several spoonfuls of peanut butter, cheese or other food to the base of the bottle on top of the gravel.

Step 4

Remove the bottle cap from the cut-off bottle top, and turn the top upside down so the spout faces down and resembles a funnel. Set the upside-down funnel into the open end of the bottle.

Step 5

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.

Step 6

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.

Step 7

Place the trap in an area where you commonly observe any mice or mouse droppings.

Step 8

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.
