How can I catch a mouse in a jar? - briefly

Place a small amount of strong-smelling bait (e.g., peanut butter) at the bottom of a clear jar, then prop the opening with a lightweight board that the mouse will dislodge to enter; once the animal is inside, swiftly slide a tight‑fitting lid over the jar to seal it. Ensure the jar sits on a stable surface and monitor it until the mouse is securely contained.

How can I catch a mouse in a jar? - in detail

Capturing a rodent with a transparent container requires preparation, bait selection, and careful execution.

First, gather the necessary tools: a wide‑mouth glass or plastic jar (minimum 500 ml capacity), a piece of flexible wire or a sturdy rubber band, a small piece of food that attracts mice (peanut butter, cheese, or seeds), and a towel or gloves for handling. Ensure the jar is clean and free of cracks.

Next, create a simple trap. Spread a thin layer of bait on the inner rim of the lid, then press the lid onto the jar so the bait is just inside the opening. Attach the wire or rubber band to the lid’s edge, leaving enough slack to allow the lid to open slightly when the mouse pushes against it.

Place the assembled device in an area where mouse activity is evident—near walls, behind appliances, or along established runways. Position it so the opening faces the wall, allowing the animal to approach naturally.

When a mouse enters and attempts to reach the bait, its weight will cause the lid to tilt outward, creating a gap for the rodent to slip inside. The wire or band will then snap the lid back into place, sealing the container.

Check the trap at regular intervals (every 30–60 minutes). Once a capture is confirmed, cover the jar with a solid lid or tape, wear gloves, and transport the sealed container to a disposal site. Release the mouse at least 100 meters from the building, or follow local humane‑euthanasia guidelines if necessary.

Maintain hygiene by cleaning the jar and surrounding area after each use to prevent scent buildup, which can deter future attempts. Repeat the process until no further signs of activity are observed.
