Living in Edmonton, you’ve probably spotted a mouse or two in your home. But do mice in Edmonton carry disease? The short answer is yes. These small rodents can spread several serious illnesses to humans. Edmonton’s cold winters drive mice indoors, making contact more likely.
Mice aren’t just annoying pests. They carry bacteria, viruses, and parasites that make people sick. When they invade your home, they leave behind contaminated droppings and urine. This creates health hazards you can’t ignore.
Do Mice in Edmonton Carry Disease? Warning Signs to Watch
Recognizing a mouse problem early reduces health risks. Look for these telltale signs:
1. Physical Evidence
- Small, dark droppings near food sources.
- Gnaw marks on food packages, walls, or furniture.
- Grease marks along walls where mice travel.
- Shredded paper or fabric for nesting.
- Small holes in walls or baseboards.
2. Sounds and Smells
- Scratching sounds in the walls or ceilings at night.
- Strong, musty odour in closed spaces.
- Squeaking or chirping noises.
3. Behavioral Signs
- Pets acting unusually alert or excited.
- Finding food crumbs in strange places.
- Discovering chewed pet food bags.
Common Diseases That Mice Spread
1. Hantavirus Pulmonary Syndrome (HPS)
This deadly virus originates from the droppings and urine of deer mice. You catch it by breathing in dust from contaminated areas. Early symptoms resemble a flu-like illness, like fever, muscle aches, and fatigue. Without treatment, it can kill.
HPS is rare but serious. Alberta has reported cases over the years. The virus survives in dried mouse waste for weeks.
2. Salmonellosis (Food Poisoning)
Mice contaminate your food and surfaces with Salmonella bacteria. You get sick by eating contaminated food or touching infected surfaces. You may feel stomach cramps, vomiting, diarrhea, and fever.
Most people recover in a week. But young children and older people face higher risks of severe illness.
3. Leptospirosis
This bacterial infection spreads through mouse urine. You catch it through cuts in your skin or by accidentally ingesting contaminated water. Symptoms start mild – headache, muscle pain, and fever.
Left untreated, leptospirosis damages your kidneys and liver. In severe cases, it can even cause death.
4. Rat-Bite Fever
Despite the name, mice also carry this disease. Their bites or scratches can infect you. Sometimes just handling a mouse is enough. The symptoms are fever, rash, and joint pain.
Children and people with weak immune systems face the highest risk.
Why Edmonton Homes Attract Disease-Carrying Mice
Edmonton’s harsh winters make your warm home irresistible to mice. These rodents seek food, water, and shelter when temperatures drop. Your house provides all three.
Urban areas have higher mouse populations. More buildings mean more hiding spots and food sources. Older neighbourhoods in Edmonton often have small gaps and holes that mice squeeze through.
Fall and winter are the seasons with the most mouse activity indoors. They’re preparing for cold weather and looking for safe nesting spots.
How Mice Spread Disease in Your Home
Understanding transmission helps you protect your family. Mice spread disease in four main ways:
1. Direct Contact
Touching live or dead mice without gloves puts you at risk. Their fur, saliva, and blood carry harmful germs. Always wear protective gear when handling rodents.
2. Droppings and Urine Contamination
Mouse waste contains concentrated bacteria and viruses. Fresh droppings look dark and moist. Old ones turn gray and crumble easily. Both are dangerous.
Mice urinate constantly as they move around. This leaves invisible contamination on surfaces, food, and fabrics.
3. Food Contamination
Mice chew through packaging to reach food. They contaminate far more than they eat. One mouse can produce 50-75 droppings per day, spreading disease throughout your kitchen.
4. Airborne Particles
Sweeping or vacuuming mouse droppings can create dangerous dust clouds. These particles float in the air for hours. Breathing them in can make you very sick.
How Can You Prevent Mice From Spreading In Your Home
Protecting your family requires proper cleanup and prevention. Never sweep or vacuum mouse droppings directly – this spreads dangerous particles into the air.
1. Safe Cleanup Steps
- Wear rubber gloves and a face mask.
- Apply disinfectant spray to the droppings and allow it to work for 5 minutes.
- Wipe away waste using disposable paper towels.
- Treat all contaminated areas with a bleach-based disinfectant solution.
- Wash your hands thoroughly afterward.
2. Seal Entry Points
Block holes smaller than a dime using effective materials and methods:
- Steel wool combined with caulk – Push steel wool into gaps first, then seal with silicone caulk.
- Hardware cloth (1/4-inch mesh) – For larger openings around vents or utility penetrations.
- Expanding foam sealant – Fill cracks around pipes, though it is less durable than other methods.
- Metal flashing – Install around foundation gaps and where different building materials meet.
- Door sweeps and weatherstripping – Seal gaps under doors and around windows.
- Copper mesh – An alternative to steel wool that won’t rust over time.
3. Remove Food Sources
Secure food storage and maintain cleanliness:
- Airtight containers – Use glass jars, plastic bins with tight-fitting lids, or metal canisters.
- Vacuum sealed bags – For bulk items like rice, flour, and cereals.
- Refrigerator storage – Keep opened packages of pet food and birdseed cold.
- Daily cleaning routine – Wipe counters, sweep floors, and clean behind appliances.
- Secure garbage – Use tight-fitting lids on trash cans and empty regularly.
4. Eliminate Water Sources
Control moisture and standing water:
- Fix plumbing leaks – Repair dripping faucets, running toilets, and pipe joints.
- Remove pet water at night – Empty and refill bowls each morning.
- Improve drainage – Clean gutters and address grading issues around the foundation.
- Use dehumidifiers – Maintain humidity below 50% in basements and crawl spaces.
- Dry wet areas immediately – Address spills, condensation, and flooding promptly.
5. Reduce Shelter Options
Minimize nesting sites and hiding places:
- Declutter storage areas – Organize basements, attics, and garages using sealed bins.
- Trim vegetation – Keep shrubs at least 3 feet from exterior walls and remove overgrown areas.
- Stack firewood properly – Store it at least 18 inches from the house on raised platforms.
- Seal storage sheds – Apply the same sealing principles to outbuildings.
- Remove debris piles – Clear leaf litter, brush piles, and unused materials from the property.

FAQ: Mice in Edmonton
1. What are the most common signs of mice in an Edmonton home?
The clearest signs are small, black droppings the size of rice grains found in cupboards or along walls. Also, look for gnawed food packages, shredded paper or fabric used for nests, and listen for scratching sounds in your walls or ceiling, especially at night.
2. How can I prevent mice from entering my house during Edmonton’s winter?
Before winter, inspect your home’s exterior and seal any cracks or holes larger than a pencil’s width using steel wool and caulk. Pay close attention to where pipes and utility lines enter your property. Also, ensure door sweeps are tight and store firewood away from the house.
3. Is it safe to clean up mouse droppings myself?
Yes, if you do it safely. Never sweep or vacuum dry droppings, as this can release virus particles into the air. Instead, wear rubber gloves and a mask, spray the droppings with a disinfectant or bleach solution, let it soak for five minutes, and then wipe it up with a paper towel.
4. Are deer mice, which carry Hantavirus, found in Edmonton?
Yes, deer mice live in Edmonton and the surrounding rural areas. They are identifiable by their brown bodies, white bellies, and two-toned tails. Due to the risk of Hantavirus, you should treat all mouse infestations with caution and follow safe cleanup procedures to prevent exposure to the virus.
5. When should I stop using DIY traps and call a professional?
Call a professional exterminator if you see mice during the day, find fresh droppings in multiple rooms daily, or if your traps haven’t caught anything for a week despite evidence of activity. Professionals can identify hidden entry points and safely handle large infestations.
6. How to identify different types of mice?
House mice are small (2-4 inches) with gray-brown fur and large ears. Deer mice have white bellies and bi-colored fur. Field mice are reddish-brown with shorter tails. Check droppings (rice-grain-sized pellets) and nesting locations to confirm species.
7. What to do if you suspect an infestation?
Document evidence, inspect common areas such as kitchens and basements, and seal entry points promptly. Set traps in high-activity areas and monitor for 2-3 weeks. Contact Major Pest Control Service if you see multiple mice, extensive damage, or have health concerns.
