How do I set a snare for mice? - briefly

Position a spring‑loaded wire loop on a flat surface, bait it with a grain morsel, and attach a trigger that releases the loop when the rodent pulls the bait. Inspect the device regularly and relocate any captured mouse to a suitable release site.

How do I set a snare for mice? - in detail

Trapping mice with a snare requires a simple device, appropriate bait, and careful placement. The method relies on a spring‑loaded loop that tightens when the rodent pulls the trigger mechanism.

Materials

  • Thin, flexible wire (stainless steel or copper, 18‑20 gauge)
  • Small piece of cardboard or plastic for the trigger base
  • Bait such as peanut butter, sunflower seeds, or dried fruit
  • Pliers for shaping the wire
  • Protective gloves for handling the snare

Construction

  1. Cut a 6‑inch length of wire. Bend one end into a small loop, leaving a 1‑inch tail.
  2. Form a second loop at the opposite end, creating a “U” shape with the tail positioned between the loops.
  3. Twist the tail around the base of the “U” to create a tension spring; the wire should resist opening.
  4. Attach the trigger base to the center of the spring using a small piece of cardboard, securing it with a tight knot.

Setting the device

  • Apply a thin layer of bait to the trigger base, ensuring it does not obstruct the movement of the spring.
  • Position the snare so that the bait sits directly under the loop. When a mouse attempts to reach the bait, its weight pulls the trigger base, releasing the tension and closing the loop around the neck.

Placement guidelines

  • Locate active runways by observing droppings, gnaw marks, or grease trails.
  • Place snares perpendicular to the runway, with the trigger facing the direction of traffic.
  • Space multiple devices 2‑3 feet apart in high‑traffic zones to increase capture probability.

Safety and disposal

  • Wear gloves when handling captured rodents to avoid disease transmission.
  • Release captured mice outdoors, at least 100 feet from the building, if humane release is desired; otherwise, euthanize according to local regulations.
  • Reset or replace the snare after each capture to maintain effectiveness.
