Though weasels, also known as ermine when they turn white, adorned the royal robes in Europe, its für doesn’t carry the same exclusivity today. Nevertheless, weasels are still trapped in the United States. When trappers are targeting weasels, many will use a weasel box. Weasel boxes are designed to hold and protect the traps used to capture weasels. The box protects the bait from the weather and larger animals that might steal the bait or otherwise interfere with the trap. The question is, what diameter should be used for the weasel box hole?

Weasel Box Hole Sizes

Different trappers use different hole sizes. Some weasel trappers prefer holes 2 inches in diameter. Other trappers like their weasel box holes to be 1.5 inches in diameter.

Why Different Hole Sizes?

Is it because weasels in northern latitudes are larger and thus require a larger hole? While more southerly weasels are smaller and only require a smaller diameter hole? If that is not the issue, then do hole sizes make a difference in capture rates both in weasel captures and avoidance of non-target captures?

Bottom Line

I would love to know the answer to this if there is one. I’ll keep an eye out for any info. But if you have some insights on the proper sizing of weasel box holes do let us know.
