Homemade Electric Mouse Trap
Use a homemade mouse trap as a less costly alternative to the regular spring-loaded trap. (mouse in trap image by Solflak from Fotolia.com)

Having mice around the house can be hazardous to your health. The small rodents are known to spread serious diseases and contagious infections. They often are attracted to filthy rooms and surfaces, as well as clutter and papers. Clothes and other objects on the floor will encourage the mice by giving them a place to hide. Exterminators and spring-loaded mice traps are some of the methods used to get rid of mice; the electric mouse trap is another alternative. These can be purchased, or you can build your own with household items.

  1. 1

    Cut four pieces of electrical wire to about 1 foot in length. Strip about 2 inches of insulation from one end of the wires and an inch off the other ends.

  2. 2

    Place one of the plywood boards on a flat surface. Lay the two metal plates on the wood approximately 1 inch apart.

  3. 3

    Mark the outline of the metal plates on the wood with a pencil.

  4. 4

    Cut the wooden piece approximately half an inch off from the outline to make the wooden piece slightly bigger than the metal plates. Do not cut two separate pieces for each metal plate. The wooden board will be wide enough for the metal to rest but narrow enough so the mouse will not remain on the board.

  5. 5

    Stick the metal plates to the wooden board 1 inch from each other with epoxy.

  6. 6

    Solder the 2-inch uninsulated ends of two wires to the first metal plate. Solder the remaining two wires to the second metal plate using the 2-inch uninsulated ends. The first metal plate will be used as positive charge while the second will be the negative charge.

  7. 7

    Twist the unoccupied end from one of the wires from the first metal plate to the positive contact on the first battery. Twist the free end from one of the wires from the second metal plate to the negative contact on the same battery.

  8. 8

    Repeat the procedures in Step 7 to join the remaining two wires to the second battery.

  9. 9

    Place the plywood board inside the dog cage. Place bait such as peanut butter on the metal plate farthest away from the entrance to the dog cage.

  10. 10

    Leave the front gate of the dog cage open to allow the mouse to enter the dog cage. When the mouse enters the cage, it will step on both metal plates and connect the positive and negative charges. Remove the wires from the batteries and discard of the mouse once it has been captured.

Tips and warnings

  • Some mice are attracted to chocolate, peanut butter, milk powder and other attractants as well.
  • Obtain a small dog cage rather than a large one to save space, but also to stop other animals from entering the cage.
  • Make sure to clean your hands after touching a mouse or the mousetrap to avoid catching diseases from the rodent.
  • Electric mouse traps can be dangerous. Make sure to handle the mouse trap and wires with care. Wear gloves for protection.
