What is used in a rat trap? - briefly
A rat trap employs a spring‑loaded bar or trigger mechanism that snaps shut when the animal takes bait such as peanut butter, cheese, or grain. Electronic versions use a battery‑powered circuit to deliver a high‑voltage shock upon contact with the trigger.
What is used in a rat trap? - in detail
Rats are attracted by food, scent or moisture, so a trap must contain an effective lure. Common baits include dried grains, peanut butter, dried fruit, fish oil, or commercial rodent attractants. The lure is placed on a designated platform or within a bait cup that prevents premature contact with the trigger.
The capture mechanism varies by trap type:
- Snap traps – a steel spring‑loaded bar rests against a release latch. When the rat disturbs the trigger, the latch releases, driving the bar forward at high speed to break the spine. The spring, trigger plate, and holding spring are calibrated to deliver sufficient force without excessive recoil.
- Glue traps – a rigid board coated with a non‑drying adhesive. The board holds a small amount of bait; the rat’s paws become immobilized upon contact. The adhesive formulation is designed to remain tacky for weeks under typical indoor conditions.
- Electric traps – a metal enclosure containing a high‑voltage, low‑current circuit. Contact plates generate a brief shock that kills the rodent instantly. Power is supplied by disposable batteries or a mains adapter, and a safety interlock prevents accidental discharge.
- Live‑catch traps – a hinged door with a spring or weighted lever. The rat enters to reach bait; pressure on the trigger releases the latch, closing the door. The interior includes ventilation holes and a smooth surface to reduce injury.
Supporting components improve reliability:
- Trigger sensitivity adjustment – a screw or sliding weight that calibrates the force required to activate the latch, allowing use with different rodent sizes.
- Safety shield – a transparent or opaque cover that protects the user from accidental contact with the killing element.
- Reset mechanism – a spring‑loaded lever that returns the trap to its armed position after each capture, minimizing handling time.
Materials commonly employed are stainless steel for durability, high‑density polyethylene for bait stations, and non‑toxic adhesives for glue surfaces. All components are designed to function in environments ranging from dry basements to damp attics, with corrosion‑resistant finishes where moisture is present.
