True weasels are small, short-legged, almost tubular predators. Their body shape allows them to access small animal burrows in pursuit of prey. Two species occur locally: the long-tailed weasel(Mustela frenata) is found statewide and the short-tailed weasel (or ermine) (Mustela erminea) prefers higher elevations from the Front Range west. Both are a chestnut brown with a pale underside in summer and pure white in winter. Both have black-tipped tails. Both are fierce predators of small rodents, rabbits and birds. As such, they are largely beneficial, especially when voles, mice and pocket gophers are abundant. Most calls we receive about weasels are more like inquiries than complaints. People don’t know what they are or what damage they do. Almost always we assure people that weasels are beneficial and not a concern. The only exception is when weasels take up residence in human structures. In such cases we can live-trap and relocate them. If we can find points of entry, we will exclude them when practical.
We’ll have more information about weasel biology, problems they pose, and solutions we offer coming soon. In the meantime, if you have a concern about weasels, call us at 719-636-1014 for an assessment and prices.
