The muskrat (Ondatra zibethica) is not actually a rat, but is classified as a rodent because of its teeth: four large, yellowish incisors in the front of its mouth. They strive on cat tails and because of this an over grown pond is a paradise for the rodents. This causes conflict between man and rodent. These creatures can be a huge annoyance when they tunnel in your banks and create tunnels for your water to seep pout, and to mention the erosion on the bank that eventually washes into the pond.
Muskrats are in your pond because of a food source. Their diet is a vegetation composed of cattails, water lilies, sedges, and pond weeds, then you may want to get rid of these with a pond clean out. You can try some chemicals or the old fashion way by hand. This is the sure way to get rid of the animals they will seek a more neutral pond elsewhere.
Trapping, is another way to get rid of these muskrats. Trapping muskrat is a very effective way to remove them from your property. Muskrat repellents and electronic device may be marginal. Trapping may be the cheapest route. Call us at pondperfection.com for your trapping needs. In some cases trapping is free of charge depending on the area.
Rip rap the inside of the pond's dam with rocks or cover it with vinyl-coated welded wire. Rocks should be flat and closely-fitted. The rock layer must be at least 8" thick, extending 3 ft. below and 1 ft. above the normal water line. If muskrats are traveling from the pond to feed infields or gardens, fence those areas. A pond aeration or fountain system will also stir up, which the muskrats do not like it will also prevent weed growth.
