How to make a simple rat trap? - briefly
Cut a 12‑inch wooden plank, hinge one end to a bucket, place bait on the free end, and attach a trigger string that releases the plank when the rat pulls it, causing the bucket to tip and confine the rodent. Inspect the trap frequently and dispose of captured animals humanely.
How to make a simple rat trap? - in detail
To construct an effective, low‑cost rodent catcher, gather the following items: a sturdy wooden board (approximately 30 × 15 cm), a metal spring bar or a strong rubber band, a thin wooden dowel (about 2 cm in diameter), a piece of fabric or felt for the trigger, a small piece of cheese or peanut butter as bait, and a disposable container for captured animals.
Begin by drilling two parallel holes near one short edge of the board, spaced 5 cm apart. Insert the spring bar through the holes so it can pivot upward, forming a lever. Attach the dowel to the opposite side of the board, aligning it with the pivot point; this will serve as the holding arm. Secure the fabric strip to the dowel’s end, creating a sensitive trigger surface.
Place the bait on the fabric strip, ensuring it does not obstruct movement. Position the board on a flat surface with the lever arm raised, then gently release the holding arm so the spring bar snaps the board shut when the trigger is disturbed. Test the mechanism by lightly touching the fabric; the board should close quickly and remain closed.
Select locations where rodent activity is evident: along walls, behind appliances, or near garbage containers. Position the trap so the bait faces the wall, allowing the animal to approach without seeing the mechanism. Check the trap at least twice daily; if an animal is caught, wear gloves, cover the board with a disposable bag, and release the creature at a safe distance from residential areas, complying with local wildlife regulations.
Maintain the device by inspecting the spring for fatigue and replacing the bait regularly to retain attraction. For larger infestations, duplicate the design and distribute multiple units to increase capture probability.
