How can I make a trap for mice and rats? - briefly

Use a snap trap baited with cheese or peanut butter, set it along walls or near entry points, and inspect it regularly. For a DIY option, create a bucket trap by attaching a floating platform with bait that tips and drops the rodent into a water‑filled container when it climbs on it.

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

To construct a reliable rodent capture device, gather the following materials: a sturdy wooden board (approximately 10 × 15 cm), a spring‑loaded steel bar, a thin dowel or nail, a piece of cloth or paper for a trigger mechanism, and an appropriate attractant such as peanut butter, dried fruit, or grain.

Begin by securing the steel bar to one end of the board with a hinge formed from the dowel. The bar should rest in a neutral position where it can be displaced easily but returns quickly when released. Attach the cloth strip to the opposite side of the board, positioning it so that when a rodent pulls the strip, the bar snaps forward. Test the mechanism with a finger to ensure rapid movement and that the board returns to its original state after each activation.

Prepare the bait station by placing a small amount of attractant on a platform attached to the trigger strip. The platform must be lightweight enough for the animal to move it, yet sturdy enough to hold the bait without collapsing. Position the entire assembly along a wall, near known rodent pathways, with the entry side facing the wall. Ensure the trap is level and stable to prevent misfires.

For a humane capture option, replace the snap bar with a hinged lid that closes when the trigger is activated. Use a spring to pull the lid shut, creating a cage that retains the rodent alive. Include ventilation holes and a smooth interior surface to minimize stress. After capture, transport the cage to a release site at least 200 m from the original infestation and open it outdoors.

Safety precautions: wear thick gloves when handling the trap, keep it out of reach of children and pets, and inspect the device regularly for wear or damage. Dispose of dead rodents in sealed bags and disinfect the trap with a bleach solution before reuse.

By following these steps, you can fabricate an effective, low‑cost device that reliably captures or eliminates mice and rats while minimizing risk to non‑target species.
