Muskrats are semi-aquatic rodents found across North America, recognizable by their stocky brown bodies, long flattened tails, and webbed hind feet. They inhabit marshes, ponds, lakes, rivers and other wetlands.
But how dangerous are these furry wetland residents? Let's explore what risks muskrats may pose.
To understand if muskrats are dangerous, it helps to first learn about their characteristics and behaviors.
Muskrats typically grow up to 2 feet long including the tail, and weigh between 2-5 pounds. Their fur is thick and water-repellent to keep them warm and dry. They are excellent swimmers and spend much of their time in water.
Muskrats live in burrows dug into the banks of rivers, lakes or marshes. Their dens have underwater entrances and chambers above the waterline. Muskrats are most active at night. During the day they tend to stay hidden in their dens.
These rodents are herbivores, feeding on aquatic plants like cattails, water lilies and rushes. They often construct feeding platforms by piling up vegetation. Muskrats sometimes strip entire areas of shoreline vegetation.
Muskrats are solitary most of the year, but seek mates during breeding season from late winter to early spring. Females can give birth to up to 8 young after a 4-week gestation. The kits nurse for about a month before venturing out on their own.
Muskrats play an important ecological role, creating channels and openings that provide habitat for other wetland species. But they can also cause damage through their burrowing and feeding behaviors.
Now that we know a bit about these wetland-dwelling rodents, let’s look at the potential risks they pose.
Muskrats generally avoid confrontations and attacks on humans are extremely rare. But there are a few potential dangers to be aware of:
Muskrats become aggressive only when they feel threatened or cornered. For example, they may attack if humans or predators encroach on their burrow.
In the unusual event a muskrat does feel provoked, it can deliver a nasty bite. Their sharp teeth can cause deep puncture wounds. Muskrats may also scratch with their claws in self-defense.
To avoid startling a muskrat, don’t approach their dens and give them space if you encounter one. Never corner or try to pick up a wild muskrat.
Like other rodents, muskrats can carry diseases transmissible to humans:
Leptospirosis: Spread through contact with urine or contaminated water. Causes flu-like symptoms.
Tularemia: Spread by ticks, mites or handling infected animals. Causes ulceration and swelling.
Lyme disease: Spread by infected ticks that live on muskrats. Causes rash, fever and arthritis.
To reduce risk of disease, avoid direct contact with muskrats, and wear protective clothing and insect repellent when in marshy muskrat habitats.
Though integral parts of wetland ecosystems, muskrats can cause problems if populations spike or they move into new areas.
Extensive burrowing can damage pond dams, levees, and irrigation ditches. Feeding activities also denude shoreline and marsh vegetation. This can increase erosion and sedimentation.
In these cases, wildlife management strategies may be needed to control muskrat populations and limit ecological damage.
So while muskrats only pose modest dangers, it’s still smart to give them space and take precautions around them.
Muskrats and humans coexist in many regions. Here are some tips for preventing conflicts:
Avoid getting too close to the water's edge around muskrat habitats.
Eliminate any easy access points like gaps in pond barriers or uncovered window wells.
Protect garden plants with fencing, and cover any fish ponds with mesh.
Keep grass mowed and clear overgrown vegetation that attracts muskrats.
Remove any burrows on your property by filling them in.
Seek professional help for severe infestations or damage.
With some simple precautions, problems with muskrats are avoidable. In most cases, you can appreciate these wetland rodents from a safe distance.
If muskrats start causing excessive harm, or you need to relocate one from your property, specialized trapping may be required.
Muskrat trapping has regulations, proper technique is important, and relocation sites must be suitable. So it's best left to licensed wildlife control professionals.
They humanely remove and relocate problem muskrats, and take actions to exclude them from areas. You can also contact local authorities for guidance.
To sum up, muskrats are not aggressive by nature, and very rarely attack or transmit diseases to people. With some smart precautions, we can coexist safely with these wetland rodents.
In the rare event of a nuisance muskrat, specialized help is advised. Muskrats play important ecological roles, so peaceful coexistence is ideal.
So while muskrats have the capacity to injure and spread illness, incidents are very uncommon. As long as you don't corner, threaten or try to handle them, muskrats present little danger.
With proper respect for their space, and care around muskrat-inhabited wetlands, we can safely appreciate these fascinating rodents from a distance!
