Every winter small field mice take up residence in my garage.
For two years I quickly got rid of them using Victor snap traps.
Last year I bought a an off brand of traps. I put out a dozen of these traps and caught only one mouse. The bait was stolen from the eleven other traps but only the one mouse was caught.
I compared the Victor traps with the off brand and found the springs on the off brand are much too strong.
I switched back to the Victor traps and have all but eliminated my mouse problem in less than a week.
