How can I make a live trap for mice? - briefly

Use a sturdy container (e.g., a 5‑gal bucket) with a smooth interior, place a ramp leading up to a small opening, and bait the far end with peanut butter or cheese; when a mouse enters, its weight tips a trigger that closes the lid, trapping it unharmed. Release the captured mouse outdoors, several hundred meters from the building, to prevent re‑entry.

How can I make a live trap for mice? - in detail

A live‑capture device for rodents can be assembled from inexpensive, readily available materials. The design relies on a trigger mechanism that releases a door when the animal enters, allowing the creature to remain inside without injury.

Materials

  • Sturdy cardboard box or plastic container (approximately 12 × 8 × 6 in).
  • Thin wooden or plastic strip (1 × 6 in) for the lever.
  • Spring‑loaded latch or a piece of stiff wire bent into a hook.
  • Peanut butter or small piece of cheese as bait.
  • Tape or glue for reinforcement.
  • Optional: mesh screen for ventilation.

Construction steps

  1. Cut an entrance hole 2 in wide on one side of the box, near the bottom edge.
  2. Attach the lever to the interior side of the lid so that it rests against the latch, keeping the door closed.
  3. Position the latch at the rear of the entrance, allowing the lever to be displaced when the mouse pushes against the bait.
  4. Secure the latch with tape or glue, ensuring it snaps shut quickly once the lever is released.
  5. Place a small amount of bait on the far side of the entrance, directly in line with the trigger mechanism.
  6. Test the trap by gently pressing the lever; the door should open, the mouse enter, and the latch should close automatically when the lever returns to its original position.
  7. Add a ventilation mesh to the top of the container if prolonged holding is anticipated.

Operation and maintenance

  • Position the trap along walls, behind appliances, or near known activity corridors, as mice travel close to surfaces.
  • Check the device every few hours; release captured rodents at least 100 ft from the building to prevent re‑entry.
  • Clean the trap with mild detergent after each use to remove scent markers that could deter future captures.
  • Replace worn latches or levers promptly to maintain reliability.

Safety considerations

  • Avoid using toxic baits; food‑based attractants prevent accidental poisoning of non‑target animals.
  • Ensure the enclosure is smooth on the interior to prevent injuries.
  • Wear gloves when handling captured rodents to reduce disease transmission risk.
