Mink are silent aquatic hunters. Their bodies were built for hunting. They are quick on land, skilled swimmers, and excellent tree climbers. These glossy, dark-brown, semi-aquatic carnivores usually measure about 20 inches in length and weigh 1.5 to 2 pounds. Typically nocturnal, some do hunt during the day. Nevertheless, it’s hard to spot them because they move so swiftly. Mink are shoreline dwellers and prey primarily on fish, frogs, muskrats, waterfowl, snakes, and other small mammals.

Minks rarely leave evidence when snatching up your fish. However, you may find a few fish scales left behind or tracks in the snow during winter. Mink have paired tracks that look very similar to cat tracks with five toes and toenail marks. Mink also enjoy tobogganing on snow which leaves long slide streaks. 

Are Mink a Concern?

A mink can single-handedly destroy your koi pond. These slippery and sneaky predators will drain your entire pond dry of fish if given the chance. Once a mink finds a food source, they will keep coming back for more. They also don’t discriminate between the size of the prey – grabbing both big and small fish. 

Here at Advanced Wildlife Control, we believe in humane animal removal and relocation. Therefore, our technicians will use baits and live traps to humanely catch mink. We will then relocate the mink at least 30 miles away from your property. Our experienced technicians have also noted that mink are more likely to prey on fish during the early winter to early spring months. Fish become slow and lethargic due to colder temperatures which make it easier for mink to snatch them.

DID YOU KNOW?Mink are related to the badger & skunk through the same weasel family.

Mink breed in February, but reproduction is dependent on the weather conditions. Good, warmer weather is favorable for the litter’s survival in the spring. A mink only has 1 litter a year with 5-6 young in the litter. The young are born only 31 days after the gestation period and remain with their mother until late summer when the young begin to go out on their own. 

Mink are common in Wisconsin, especially near water sources and shorelines. Minks are very territorial, especially males during the breeding season. They will stick to their territory – being creatures of habit – and visit similar places each hunting trip throughout their area.
