Mice are one of the smallest household rodents. They are intelligent creatures that invade homes in search of food, water, and shelter. The biggest issue is their incredible reproduction rate: just a couple mice can explode into hundreds within months.
Once infestations reach exponential growth, mice consume everything in their path, reaching plague levels that wipe out agricultural harvests, cause immense structural damage, and spread deadly diseases.
Mus Musculus
Most common invasive household mouse. Found worldwide wherever people are. Also a popular pet.
Field Mouse
Grayish fur resembling deer color. Distinguished by bicolored tail.
Bicolored coat: light brown/red top with white feet and underbelly. Avoids human contact but may enter homes.
Brown with white belly and faint white stripe on back. Excellent climbers using longer tail for stability.
Large ears and extremely long tail. Brownish coat mixed with darker hairs and white belly.
House mice are extremely social, creating colonies with one dominant male and several females. Males are aggressive toward non-related males but coexist with males from their own litters. Mice are nocturnal and spend most of the night searching for food.
Opportunistic scavengers eating anything humans eat. Prefer grains, cereals, seeds, nuts, fruits, and bugs. Chew through plastic, cardboard, and paper. Eat 15-20 times per day, establishing territory close to food.
Year-round breeding. One female: up to 10 litters/year with 8 pups each. Sexual maturity at 4-7 weeks. Gestation only 21 days. Wild lifespan: 1-2.5 years. Pet mice: up to 6 years.
Prefer quiet, undisturbed places. Destroy linens, upholstery, and insulation for nesting materials. Found in cabinets, pantries, wall cavities. Wild mice burrow underground for predator protection.
Warm-blooded creatures needing warm, safe places in colder months. Can sense heat through windows. Search for cracks and openings to access warmth.
Excellent sense of smell. Gravitate toward trash, outdoor BBQs, bird feeders. Once they find your home, they find their way inside for abundant food.
Need small amounts of water. Leaky faucets, pipes, and under sinks provide enough hydration to survive.
Mice fit through any hole the size of a dime. Entry points include:
Mice pose serious threats to health and property. They are disease vectors and will ravage property in search of food.
Destroy gardens, fruit trees, crops. Chew through drywall, wiring, insulation, baseboards, gas lines, pipes, and wood. Damaged wiring/gas lines cause fires and gas poisoning.
Extremely rare; only when threatened or cornered. Can transfer disease, viruses, or bacteria. Seek medical attention if bitten.
Spread via bites, parasites (fleas), contaminated food, urine and waste. Diseases include: Hantavirus, Salmonellosis, Leptospirosis, Lymphocytic chorio-meningitis, Bubonic plague (via fleas).
Seal access points: open vents, foundation cracks, space around pipes/conduit, gaps under doors. Fill with steel wool and seal with caulking. Steel wool prevents chewing through.
Keep areas clean of food, trash, and debris. Seal food sources. Remove potential harborage points that mice use to access your home.
Snap traps are most common and effective: reusable, humane, no handling of live mice. Other options: glue traps, live traps, electrocution boards.
Rodenticides best for outdoor infestations to prevent mice dying in wall cavities. Slow-acting allows mouse to leave poison source. Risk of secondary poisoning in food chain.
Wear gloves, respiratory mask, safety goggles. Air out area 30 min before cleaning (hantavirus risk). Never use brooms or vacuums (stirs up contaminated waste). Use bleach/water mix and paper towels. Seal and dispose of all contaminated materials properly.
If you have seen mice or signs of mice activity, call EcoGuard Pest Management to ensure your mouse problem is treated immediately. Schedule your rodent inspection with a licensed and trained EcoGuard rodent specialist.
Mice are primarily attracted to food and shelter which are generally abundant in most homes. By keeping your home clean, you can prevent mice from finding the food they need to survive.
Mice have an excellent sense of smell and are generally deterred by ammonia, cat urine, vinegar, and strong herbal scents like peppermint, cloves, and cinnamon.
If you have one mouse, there are likely others nearby. Mice procreate fast and are social creatures that often belong to a family group.
A solitary mouse may not be the end of the world, but it is not recommended to leave mice untreated due to their rapid reproduction capabilities.
