When it comes to keeping your home safe, most folks in Western Montana are more worried about voles or ground squirrels tearing up the lawn. But there’s another pest-related problem you might not have considered—hantavirus. This rare but potentially deadly disease is something every Montanan should be aware of, especially if you’re dealing with rodent issues.

What is Hantavirus?
Hantavirus Pulmonary Syndrome (HPS) is a severe respiratory disease caused by hantaviruses. It’s most commonly spread through contact with rodent urine, droppings, or saliva. Breathing in contaminated dust is the most frequent way people get infected, especially when cleaning up areas that have been home to mice or rats.
Is Hantavirus Found in Montana?
Yes, hantavirus is present in Montana. In fact, Montana has reported several cases over the years, with some resulting in fatalities. The most common carrier here is the deer mouse (Peromyscus maniculatus), which is found throughout the state. These mice are known for their brownish fur with a white belly and can easily get into homes, garages, cabins, or sheds.

Who is Most at Risk?
Anyone who comes into contact with rodent-infested areas can be at risk, but the danger is higher for people who:
Clean out cabins, sheds, or garages that have been unused for a while
Handle firewood piles or storage areas where mice might nest
Perform home renovations or cleanups in older buildings
Camp or hike in areas with heavy rodent activity
How to Reduce Your Risk
Seal up entry points: Make sure rodents can’t get into your home or cabin. Seal gaps around doors, windows, pipes, and any small openings.
Keep it clean: Store food securely and regularly clean areas prone to rodent activity.
Be careful when cleaning: If you find signs of mice, do not sweep or vacuum droppings. Instead, wear gloves and a mask, spray the area with disinfectant, and carefully wipe it up.
Call the experts: If you suspect an infestation, it’s better to call professional pest control than to handle it yourself.
