While mice may seem like tiny, harmless rodents, they can pose health risks if not handled properly. Do mice carry diseases? Yes, and the diseases can be transmitted to humans. It is crucial to understand how diseases are spread, the details of each disease, and how to avoid them. One of the safest ways is to allow qualified professionals, such as those at Critter Control, to eliminate any disease risks.

How Do Mice Spread Diseases to People?

Mice can spread diseases to people in various ways, some more obvious than others. You may not realize that what seems like a simple task — like getting rid of a mouse — can lead to accidental exposure to diseases. Examples of how diseases are spread include:

Contaminated Surfaces

Wherever a mouse travels, it leaves behind urine and feces trails. They usually travel along countertops, floors, baseboards, appliances, and pantries in search of food. If you clean these areas without proper protection, you will expose yourself to diseases.

Airborne Particles

Mouse urine and feces harbor disease-causing organisms and can harbor mold spores that can float through the air. If mice build nests in your air ventilation systems, the spores can travel throughout your home and into your living spaces, where they linger until they are inhaled.

Direct Contact

Handling a live mouse puts you at risk of being bitten or scratched and of contracting a disease. Bacteria in mouse saliva and under their nails can lead to dangerous infections. Handling a dead mouse means you may get parasites that are still alive on the rodent’s body. Parasites also carry diseases.

Contaminated Food

Mice contaminate cereals, grains, and other groceries they can access through packaging they can chew, such as plastic or cardboard, or by nibbling on leftovers left out on the counter. If you accidentally consume contaminated food, you may also ingest pathogens left behind by the mice.

To avoid these risks and protect your family and pets from diseases, contact a professional who can help.

Most Common Diseases Carried by Mice

Hantavirus and the Hantavirus Pulmonary Syndrome (HPS)

Hantavirus is transmitted through mouse saliva, urine, and droppings. It mimics the flu, and doctors may misdiagnose you based on your symptoms, including headaches, dizziness, coughing, digestive issues, shortness of breath, and chest tightness.

Hantavirus is a serious disease that comes from rodents. There is no anti-viral treatment, medical professionals can only provide supportive care as the body works to heal itself.  

It spreads to people through airborne micro-particles picked up from rodent urine, droppings, or saliva.  This can happen when hidden contamination is disturbed in areas like attics or during improper cleanup. Many people vacuum or dry sweep feces and urine without realizing it can release particles into the air that may be inhaled in the home.


Because of this, cleanup needs to be handled carefully. Trained professionals are the safest option, with proper safety gear, sanitization products, and the knowledge needed to fully remove traces of rodent activity.

Lymphocytic Choriomeningitis (LCM)

LCM is primarily hosted in the house mouse and transmitted by bite or exposure to their bodily fluids. Initial flu-like symptoms may also include a sore throat, cough, testicular pain, and digestive issues.

Salmonellosis

Salmonellosis is a type of food poisoning that starts in the intestinal tracts of rodents. You may get this by accidentally eating foods contaminated with mouse droppings or by handling their urine or droppings. You may experience diarrhea, vomiting, fever, and stomach cramps.

Leptospirosis

Leptospirosis is also a form of food poisoning. Initial symptoms make you feel like you have the flu, with fever, chills, headaches, muscle aches, vomiting, and diarrhea. This illness can also occur from accidentally eating contaminated food or handling urine or feces.

Tularemia

Tularemia is a bacterium that can trigger inflammation in your lymph glands, eyes, and throat. Sub-symptoms include mouth sores, flu-like symptoms, and breathing troubles. Tularemia may be contracted by handling contaminated food or by inhaling spores that float through the air in dust.

Parasite-Borne Mice Diseases

Parasites latch onto mice and hide in their fur. If you get close to or handle a mouse, you risk contracting a parasite. If they are infected with bacteria, you can get sick. Some of the most common parasites found on rodents include:

  • Ticks, which vary by region, can spread diseases such as Lyme disease and tularemia.
  • Fleas can indirectly spread diseases such as tularemia and trigger allergies.

Ticks and fleas can also put you at risk for tapeworms, allergies, and skin irritations. Fortunately, there are specific steps you can take to avoid contracting ticks, fleas, and other parasites.

What NOT to Do

When encountering a mouse, try not to panic and rush to get rid of it. Using the wrong method can put you at greater risk of harm. Examples of what not to do include the following:

Do NOT Vacuum or Sweep Droppings

Many people vacuum or sweep feces and urine without realizing they release spores into the air, which can be inhaled by anyone in the home, potentially causing respiratory problems and other issues.

The best cleaning solution is provided by professionals who have proper safety gear, sanitization products, and know how to remove all traces of mouse activity.

Do NOT Handle Live or Dead Mice

Homeowners who find a dead mouse may think it is okay to pick it up by the tail and fling it outdoors. However, this is not safe because you can accidentally come into contact with the mouse’s still-living parasites or its body fluids, sharp teeth, and claws. You may also expose pets to diseases.

Instead, put the mouse in a container, compost it, bury it, or burn it. Or let the professionals who use personal protective equipment (PPE) help you avoid diseases from mice, whether they are alive or dead.

Do NOT Dispose of Mice Nests

Mice nests can harbor viruses, bacteria, and parasites that you find in other areas of your home because rodents leave urine and mouse droppings where they sleep. Disturbing a nest releases spores into the air, exposing your family to diseases like hantavirus. Removing a nest requires disinfectant, proper disposal in sealed containers, and safety gear to avoid contact.

Professional mouse control technicians have the best commercial sanitization products and equipment to ensure you and your family do not suffer accidental exposure while addressing your mouse problem.

We had such a great experience with Critter Control at every interaction. Many months ago, my friend and I called to get some advice on how to handle a bat in our home. The lady we spoke with took the time to give us free, down to earth, real advice. I remembered the experience so when it came time to batproof our attic, they are who we called. The gentleman that came out to do the quote was thorough and patient in explaining everything. The gentlemen that did the bat proofing were quick, efficient and friendly. A few months later we had them back to clean out and insulate our attic. Very friendly crew, extra helpful, and were respectful to our home and good with our German Shepherd. Just a stellar experience all around. Recommended them to my friend, and I'll recommend them to you!

I have used this company many times for all different things. They always respond as fast as possible. Wasp problem? Bug problem? Call them! The honesty that was shown when things aren’t truly needed shows that if you need pest services, call Critter Control first. You will get honest and thorough services. And you will call them again if you need it. 5 stars.

I couldn’t be happier with my experience with Critter Control and, especially, with Taylor and his partner. Taylor called the evening before my appointment to confirm and took the time to explain what they would be looking for and what the inspection would involve. He also let me know that I would receive a written estimate when they were finished, which I really appreciated. The next morning, Taylor called before arriving and showed up right within the scheduled window. He introduced himself and his partner, and they were both extremely professional and courteous. They took their time inspecting the yard and ultimately determined that I was dealing with both moles and gophers. Taylor walked me through the treatment options, answered every question I had, and made sure I understood what they were recommending. There was absolutely no pressure, and I really appreciated how straightforward and transparent the entire process was. I had a written estimate in hand within about 10 minutes of them completing the inspection. From the initial phone call to the completion of the inspection, everything was handled professionally and exactly as promised. It’s refreshing to deal with people who communicate well, show up when they say they will, and genuinely take the time to answer your questions. Thank you, Taylor, for making the process so easy. I’m very happy with the experience and would definitely recommend Taylor and Critter Control!

I had a appointment with Moises today to investigate noises that I had been hearing in my wall. I explained what I had been hearing and for how long, and he said that he was going to look for any potential entry points. He found two areas that were compromised and showed me pictures of the areas, and told me what he thought was the culprit and also explained the plan to make sure that there weren't any other rodents in the wall by putting in a one way door and then after 5 days, they would sanitize the area in the wall and seal up the two areas, so that nothing else could get inside. He was very professional and friendly and explained everything to me that they were going to do to alleviate the situation. I would definitely recommend Moises and Critter Control for any wildlife removal services in the future.
