Mink are fearless and voracious predators that will stay and defend itself from animals much larger than they are. Mink are carnivores that can take down an animal twice it’s size. We have seen a mink take a butterfly koi over twice its size out of a large koi pond! The diet of the mink consists of any meat they can get their paws on including crayfish, frogs, fish, small mammals, birds, ducks and other water foul. Mink will not eat water plants or control algae.
Mink can decimate your fish population regardless of whether you have a large pond or a water garden pond. A mink can swim underwater for 100 feet without coming up for air! During winter look for small animal tracks that lead to and from a hole in the ice of your pond. Mink usually carry and stash their prey to a protected spot like under a deck, shed or bushy covering nearby. Look for signs of a fight like small drops of blood or fish scales.
If you think you have a mink problem there are professional trappers in the phone book that can give you a hand relocating these terrifyingly adorable creatures.
