Weasels reaching five to six years are regarded as fully mature. Individuals as old as 10 are considered ancient. How to find a weasel Weasels are easiest to see in winter when leaf cover is gone and a thin layer of tracking snow will show their whereabouts in the neighborhood.

A weasel will stop to poke its little head into every hole, nook and cranny it can probe.
