How do you adjust a mouse trap? - briefly
Pull the spring arm back until the latch snaps, place the bait, and let the arm rest in the ready position; if the trigger is overly sensitive, reduce spring tension by loosening the adjustment screw on the arm.
How do you adjust a mouse trap? - in detail
Adjusting a snap‑type mouse trap requires precise alignment of the spring, bar, and trigger plate to ensure reliable closure.
First, inspect the device for damage. Replace bent springs or cracked wooden bases before proceeding. Clean all moving parts with a dry cloth to remove dust that could hinder motion.
Next, set the spring tension. Hold the spring‑loaded bar with one hand while pulling the trigger plate back until it clicks into the locked position. The bar should be under full tension but not over‑stretched; excessive force can cause the spring to lose its snap.
To fine‑tune sensitivity, adjust the position of the trigger plate relative to the bait groove:
- Place a small amount of bait in the groove.
- Gently slide the trigger plate forward or backward in 1‑mm increments.
- Test the release by lightly touching the bait; the bar should snap shut with minimal disturbance.
- If the trap fires too easily, move the plate slightly farther from the bait; if it fails to trigger, move it closer.
Secure the trigger plate by pressing it until it locks firmly into the base. Verify that the bar snaps shut cleanly when released.
Finally, conduct a functional test. Pull the trigger plate back, set the bait, and release. Observe the bar’s motion; it should travel the full distance and close the jaws with a sharp snap. If any hesitation occurs, repeat the tension and plate adjustments.
Regularly check the trap’s alignment, especially after multiple uses, to maintain consistent performance.
