Hantavirus in Florida: What Every Homeowner Needs to Know

If you’ve been following the news lately, you may have heard the word “hantavirus” popping up more and more. It’s a disease that doesn’t make many headlines until an outbreak grabs attention — and when it does, it can be alarming. As a pest control professional, I want to cut through the noise and give you the facts. Because here’s the truth: hantavirus has always been a risk wherever rodents are present, and your home may be more vulnerable than you think.

The good news? There are real, practical steps you can take to reduce that risk significantly — and professional pest control is one of the most important tools in your corner.

What Is Hantavirus?

Hantavirus is a group of viruses carried primarily by rodents, especially deer mice, cotton rats, rice rats, and white-footed mice. In the United States, the most serious form of illness caused by hantavirus is called Hantavirus Pulmonary Syndrome (HPS) — a severe respiratory disease that can be life-threatening.

According to the Centers for Disease Control and Prevention (CDC), HPS has a fatality rate of approximately 38%. That’s not a number to take lightly. While the total number of confirmed cases in the U.S. is relatively low compared to other diseases, the severity of the illness makes prevention absolutely critical.

How Do People Get Hantavirus?

The only version of the hantavirus that you can contract through another person is the Andes virus. You mostly get it from rodents — specifically through contact with their droppings, urine, saliva, or nesting materials. Here are the most common ways people are exposed:

Breathing in contaminated air — The most common route. When rodent droppings or urine dry out and become disturbed (from sweeping, cleaning, or just walking through an infested area), tiny virus-carrying particles become airborne. Breathing those particles in is enough to get infected.
Direct contact — Touching rodent droppings or nesting materials and then touching your mouth, nose, or eyes.
Rodent bites — Though rare, a bite from an infected rodent can transmit the virus.

This is why hantavirus is so sneaky and so dangerous. You don’t have to see a rodent or even know one was in your home to be exposed.

Why Florida Homeowners Should Pay Attention

Florida’s warm, humid climate makes it a year-round haven for rodents. While the species associated with HPS in the U.S. are more common in rural and western states, Florida has its own cast of rodent villains — including roof rats and Norway rats — that can carry other diseases and create the same type of contamination risks in and around your home.

As rodent populations grow and the climate shifts, the range of rodent-borne illnesses is expanding. Public health experts are watching hantavirus trends closely, and the bottom line for Florida homeowners is clear: a rodent problem is never just a nuisance. It’s a health risk.

Signs You May Have Rodents in Your Home

Many homeowners don’t realize they have a rodent problem until it’s already serious. Here’s what to watch for:

Droppings — Small, dark pellets near food, under sinks, in cabinets, or along walls
Gnaw marks — On wood, wiring, food packaging, or insulation
Scratching sounds — Especially at night in walls, attics, or under floors
Rub marks — Greasy streaks along baseboards or walls where rodents travel regularly
Nesting materials — Shredded paper, insulation, or fabric in hidden corners
A musky odor — A persistent smell in certain areas of the home

If you spot any of these signs, don’t wait to act. Rodent problems do not go away on their own — they get worse.

The Danger of DIY Rodent Cleanup

One of the biggest mistakes homeowners make when they discover a rodent problem is grabbing a broom and sweeping up droppings. This is exactly how many hantavirus exposures happen.

Sweeping, vacuuming, or disturbing dry rodent droppings sends contaminated particles into the air where you can breathe them in. The CDC recommends specific safety protocols for cleaning up after a rodent infestation, including wearing gloves, using a disinfectant spray to wet droppings before wiping them up, and double-bagging all waste before disposal.

If the infestation is significant, professional cleanup is the safest route. A trained pest professional knows how to handle contaminated materials without putting you or your family at risk.

How Professional Pest Control Reduces Your Hantavirus Risk

This is where I’ve seen the biggest difference over my career: homeowners who invest in professional rodent control don’t just eliminate the immediate problem — they break the cycle.

Here’s how a professional rodent control program protects your home and your health:

1. Thorough Inspection

A proper rodent control service starts with a full inspection of your property — roof, perimeter, attic, crawl spaces, and the interior. Rodents are experts at hiding, and entry points are often in places most homeowners would never think to look. A trained eye can spot a gap the size of a quarter in your roofline or foundation that’s serving as a rodent highway into your home.

At Prodigy Pest Solutions, our Florida rodent control process starts with exactly this kind of comprehensive inspection. Our technicians photograph every entry point and sign of activity so you see exactly what we see — before any work begins.

2. Sealing Entry Points (Exclusion)

Finding entry points is only valuable if you seal them. Exclusion — physically blocking the ways rodents get into your home — is the most important step in long-term rodent control. Without it, you can trap and bait all you want, but new rodents will keep moving in.

Our team seals all identified entry points using professional-grade materials that rodents can’t gnaw through. This is the step that actually stops the problem, not just treats the symptoms.

3. Trapping Active Infestations

If rodents are already inside when exclusion work is done, we set traps to catch any that were sealed in. Follow-up visits ensure traps are checked, replaced, and that the infestation is fully resolved. This approach — inspect, seal, trap, follow up — is what separates a lasting solution from a temporary fix.

4. Ongoing Monitoring and Prevention

Rodent pressure doesn’t stop after one service. Part of a strong pest management plan is ongoing monitoring, especially in a state like Florida where rodents are active year-round. Our Florida general pest control plans include regular inspections that catch new activity before it becomes an infestation.

What You Can Do Right Now to Reduce Risk

While professional pest control is your best defense, there are steps every homeowner can take today to make their property less attractive to rodents:

Inside the home:

Store all food (including pet food) in sealed, hard-sided containers
Keep kitchen counters and floors free of crumbs and spills
Seal gaps around pipes, vents, and utility lines with steel wool or caulk
Declutter storage areas — rodents love dark, undisturbed piles of stuff
Check under sinks regularly for signs of droppings or gnaw marks

Outside the home:

Keep trash cans sealed with tight-fitting lids
Remove brush piles, woodpiles, and debris near the foundation
Trim tree branches that overhang or touch your roofline (roof rats use these as highways)
Don’t leave pet food or water bowls out overnight
Fix any leaks or standing water — rodents need water sources

If you find droppings:

Don’t sweep or vacuum — wet the area with a disinfectant spray first
Wear disposable gloves
Use paper towels to wipe up droppings, double-bag the waste, and dispose of it
Wash your hands thoroughly afterward
Call a professional to assess the extent of the infestation

Hantavirus Symptoms: Know the Warning Signs

If you’ve had potential exposure to rodent droppings or urine, knowing the symptoms of HPS could save your life. Early symptoms typically appear 1 to 8 weeks after exposure and can feel like the flu:

Fever and chills
Muscle aches (especially in the thighs, hips, and back)
Headaches
Fatigue
Nausea, vomiting, or abdominal pain

Within 4 to 10 days, the disease can progress rapidly to include severe shortness of breath as the lungs fill with fluid. This is a medical emergency. If you’ve had potential rodent exposure and develop these symptoms, go to the emergency room immediately and tell your doctor about the possible exposure.

Early medical intervention is critical. There is currently no specific antiviral treatment for hantavirus, but supportive care in a hospital setting can be life-saving.

Frequently Asked Questions About Hantavirus

Q: Can I get hantavirus from a dead rodent? Yes. The virus can survive in a dead rodent for several days. Never handle a dead rodent with bare hands. Use gloves, place it in a sealed plastic bag, and dispose of it properly.

Q: Is hantavirus contagious between people? In the U.S., hantavirus is not transmitted from person to person. The North American strains are spread only through contact with infected rodents and their waste. Only the Andes virus spreads from person to person. As of May 11, one peson in the United States has tested positive for the Andes Virus, and they are in Nebraska.

Q: Does hantavirus exist in Florida? While the primary hantavirus associated with HPS (the Sin Nombre virus) is most common in the western U.S., Florida does have rodent populations that may carry related viruses. Any rodent infestation poses health risks and should be addressed promptly.

Q: How effective is pest control at preventing hantavirus? Very effective. Rodent exclusion and population management are the two most important factors in reducing hantavirus exposure risk. Removing rodents from your home and sealing entry points dramatically lowers the chance of any contact with contaminated materials.

Q: What should I do if I find a large number of rodent droppings? Do not clean it up yourself. Leave the area, ventilate it if possible (open windows and leave for 30 minutes before re-entering), and contact a professional pest control company. A large amount of droppings indicates a significant infestation that requires professional assessment and safe cleanup.

Q: How quickly can a rodent infestation grow? Rapidly. A single pair of rats can produce dozens of offspring per year. A small problem can become a serious infestation in a matter of months, which is why acting quickly is so important.
