How can a mouse trap be made at home using a bottle? - briefly

Cut a plastic bottle in half, invert the upper section so the neck points downward, and attach a baited trigger (such as cheese on a small stick) that releases the lid when the mouse pulls it. Place the device on a flat surface; the mouse enters, the bait activates the trigger, and the bottle snaps shut, trapping the rodent.

How can a mouse trap be made at home using a bottle? - in detail

A plastic beverage container can serve as an effective rodent catcher when assembled correctly.

Materials

  • One‑liter clear soda bottle, cleaned and dried
  • Scissors or a sharp knife
  • A sturdy stick or wooden dowel, about 15 cm long
  • Thin wire or a strong elastic band
  • Peanut butter, cheese, or dried fruit for bait
  • Tape (optional)

Construction

  1. Cut the bottle near the base, leaving a 5‑cm section of the neck and a 10‑cm wide opening.
  2. Invert the cut neck so the funnel points downward; insert it into the remaining bottle body, forming a trap entrance.
  3. Secure the junction with tape or a rubber band to prevent leakage.

Trigger mechanism

  1. Poke a small hole near the rim of the bottle body, large enough for the stick to pass.
  2. Insert the stick through the hole, allowing it to rest on the bottle’s interior edge, creating a lever that holds the inverted neck open.
  3. Attach a length of wire or elastic to the stick’s free end and anchor it to the bottle’s outer wall.

Bait placement

  1. Apply a thin layer of attractant on a small piece of cardboard or directly on the bottle’s interior floor.
  2. Position the bait just beyond the neck opening, ensuring the mouse must push the neck to reach it.

Operation

  1. Release the stick so the neck remains propped open.
  2. When a mouse enters and attempts to obtain the bait, its weight forces the neck to collapse, pulling the stick inward and sealing the entrance.
  3. The wire or elastic tightens automatically, preventing the animal from escaping.

Placement and maintenance

  • Set the device along walls, near known droppings, or close to food sources.
  • Check daily; dispose of captured rodents promptly, wearing gloves.
  • Clean the bottle thoroughly after each use to maintain hygiene.

This method utilizes basic household items to create a reliable, low‑cost solution for controlling indoor mice without chemicals.
