How to make a mouse trap?

How to make a mouse trap? - briefly

Construct a snap trap from a small wooden board, a spring‑loaded bar, a nail, and bait, positioning the bar so it releases when the mouse pulls a trigger mechanism. Place the trap along walls or near entry points and inspect it frequently.

How to make a mouse trap? - in detail

A functional rodent capture device can be built from inexpensive components and deployed quickly.

Materials

  • 1 wooden block (approximately 5 cm × 5 cm × 2 cm)
  • 1 steel spring, 5 cm long, with a hook at one end
  • 1 thin metal or plastic lever (about 10 cm)
  • 1 piece of nylon string, 30 cm long
  • 1 small piece of cardboard or plastic for the trigger plate
  • Bait (peanut butter, cheese, or grain)

Tools

  • Small drill with 2 mm bit
  • Pliers
  • Screwdriver or small nail
  • Wire cutter

Construction steps

  1. Drill a hole through the center of the wooden block, 2 cm deep.
  2. Insert the spring into the hole, allowing the hook to protrude from the top surface.
  3. Attach the lever to the hook so that the free end rests on the trigger plate. The lever should be under slight tension, ready to snap back when released.
  4. Secure the nylon string to the lever’s free end, run it around the block, and fasten it to the opposite side of the block, creating a tensioned line that holds the lever in the cocked position.
  5. Position the trigger plate beneath the lever; when a mouse steps on the plate, the string releases, the spring drives the lever forward, and the animal is confined against the block.

Bait placement

  • Apply a pea‑size amount of peanut butter to the center of the trigger plate.
  • Ensure the bait does not obstruct the lever’s movement.

Deployment guidelines

  • Place the trap along walls, behind appliances, or near known activity trails.
  • Position the device with the lever facing the wall, as rodents prefer to travel close to vertical surfaces.

Safety and disposal

  • Wear gloves when handling captured rodents.
  • Release live catches outdoors, at least 100 m from the residence, or dispose according to local regulations.
  • Reset the mechanism by re‑tensioning the string and re‑checking spring alignment.

Following these precise steps yields a reliable, low‑cost solution for controlling mouse infestations.
