Why It's Urgent
The Real Threat Inside Your Walls
Mice are more than a nuisance — they're a genuine health, safety, and structural threat that multiplies quickly if left unaddressed.
Disease transmission
Mice are known carriers of Hantavirus, Salmonella, Leptospirosis, and Lymphocytic Choriomeningitis (LCMV) — spread through droppings, urine, and direct contact with contaminated surfaces.
Food contamination
A mouse contaminates far more food than it consumes — leaving urine trails, droppings, and pathogens on every surface it travels across, including countertops, pantry shelves, and food packaging.
Structural damage
Beyond wiring, mice chew through insulation, drywall, wood framing, PVC pipes, and HVAC ducting — causing ongoing damage that often goes unnoticed until repairs become expensive.
Electrical fire hazard
Mice gnaw constantly to wear down their ever-growing teeth. Chewed electrical wiring inside walls is one of the leading causes of house fires with no apparent source — and one of the most overlooked mouse dangers.
Explosive reproduction
A single female mouse can produce up to 60 offspring per year. A small infestation becomes a severe one within weeks — and every week of delay makes treatment more complex and costly.
Secondary pest attraction
Mice bring fleas, ticks, and mites into your home on their fur. A mouse infestation can quickly trigger a secondary infestation of biting parasites throughout the property.
Know Which Mouse You're Dealing With
Different mice species have different behaviors, nesting preferences, and movement patterns. Proper ID ensures the right treatment strategy from day one.
House Mouse (Mus musculus)
The most widespread indoor rodent in North America. Small, grey-brown, and highly adaptable — they nest in wall voids, behind appliances, and inside insulation. Curious explorers that regularly follow new routes, making bait and trap placement straightforward for trained technicians.
White-Footed Mouse (Peromyscus leucopus)
Mice are known carriers of Hantavirus, Salmonella, LeptospirosA Lyme disease reservoir host that carries and transmits the bacteria to ticks, which then bite humans. Common in suburban and wooded areas, white-footed mice are a significant vector concern and should be addressed promptly when found near homes.is, and Lymphocytic Choriomeningitis (LCMV) — spread through droppings, urine, and direct contact with contaminated surfaces.
Deer Mouse (Peromyscus maniculatus)
The primary carrier of Hantavirus — a potentially fatal respiratory illness. Deer mice migrate indoors in fall seeking warmth, nesting in garages, sheds, and crawl spaces. Their droppings must be handled with extreme caution using proper respiratory protection.
Field Mouse (Apodemus sylvaticus)
Field mice enter homes in autumn through foundation gaps and utility penetrations. They're excellent climbers and often found nesting in attics and upper wall voids — making them harder to locate than ground-level species without a thorough inspection.
Species We Treat
How They Get In
A Mouse Can Squeeze Through a Gap the Size of a Dime
Exclusion is a core part of any lasting mice treatment. We don't just eliminate the current infestation — we identify and seal every entry point they used to get in.
Foundation cracks & gaps
Even hairline cracks in concrete foundations and slab edges are wide enough for a mouse. We inspect the full perimeter at ground level.
Vents & HVAC openings
Uncapped dryer vents, crawl space vents without screens, and damaged HVAC returns are frequently used entry and nesting corridors.
Utility pipe penetrations
Gaps around gas lines, water pipes, and electrical conduits entering the building are among the most common and overlooked entry points.
Roof & soffit gaps
Mice are strong climbers. Gaps at rooflines, deteriorating soffit boards, and openings around fascia allow attic access from the exterior.
Gaps under doors & thresholds
Worn door sweeps, gaps under garage doors, and damaged thresholds provide easy ground-level access — especially in older homes.
Attached garages
Garages are one of the most common entry points into a home — gaps under the garage door and through the wall connecting to the house interior are frequent pathways.
Our Process
DND Pest Control's Complete Mice Elimination Approach
Full property inspection
We conduct a thorough interior and exterior inspection — identifying active runways, nesting sites, droppings, gnaw marks, rub marks, and all potential entry points.
Infestation assessment
We gauge the severity and extent of the infestation — distinguishing between a new incursion and a long-established colony — to design the right treatment intensity.
Strategic trap & bait placement
We place snap traps, bait stations, and tamper-resistant devices along active runways and near nesting areas — positioned for maximum effectiveness and safety.
Exclusion & sealing
We seal identified entry points using steel wool, hardware cloth, caulk, and expanding foam — the only way to achieve lasting results and prevent re-entry.
Sanitation guidance
We provide a customized checklist of sanitation and structural recommendations — eliminating the food sources, harborage areas, and conditions that attracted mice.
Follow-up & monitoring
We return to check trap activity, confirm elimination, refresh bait stations if needed, and verify that exclusion work is holding before closing the job.
Health Risks
Diseases Mice Carry Into Your Home
Mice aren't just unsettling — they're active disease vectors. Understanding the health risks reinforces why professional, thorough treatment matters.
Hantavirus Pulmonary Syndrome
Spread by deer mouse droppings, urine, and nesting material. Transmitted by inhaling contaminated dust — sweeping or vacuuming mouse droppings without protection is extremely dangerous.
Leptospirosis
Spread through mouse urine contaminating water or soil. Can cause severe kidney and liver damage in humans — particularly dangerous in areas where mice have access to standing water or food storage.
Lymphocytic Choriomeningitis (LCMV)
Carried by the common house mouse, LCMV can cause neurological illness and is especially dangerous during pregnancy — potentially causing birth defects or miscarriage.
Salmonellosis
Mice carry Salmonella bacteria in their digestive tracts, contaminating food preparation surfaces, stored food, and utensils as they travel — causing severe gastrointestinal illness.
Lyme Disease (indirect)
White-footed mice are the primary reservoir for Lyme disease bacteria. Ticks feed on infected mice and then transfer the pathogen to humans — making indoor mouse control a critical part of Lyme prevention.
Fleas, Ticks & Mites
Mice entering a home bring external parasites on their fur. A mouse infestation can rapidly seed a secondary flea or mite infestation throughout carpets, furniture, and pet bedding.
Warning Signs
Signs You Have a Mouse Problem
Small dark droppings along walls or in cabinets
Mouse droppings are rice-shaped, 3–6mm long, and dark brown. Finding them along baseboards, behind appliances, or in food storage areas is one of the clearest signs of activity.
Gnaw marks on food packaging or wood
Mice constantly chew to manage tooth growth. Look for rough, irregular gnaw marks on cardboard, plastic food containers, wood trim, and wiring insulation.
Scratching or scurrying sounds at night
Mice are primarily nocturnal. Sounds of movement inside walls, above ceilings, or under floors in the late evening or before dawn are a telltale sign of an active colony.
Grease or rub marks along baseboards
Mice follow the same routes repeatedly, leaving dark grease smears from their fur along walls and baseboards — most visible on light-colored paint near entry points.
Nesting materials in hidden areas
Shredded paper, insulation, fabric, or plant material gathered into a compact ball — typically found behind appliances, inside drawers, or in wall voids — is a confirmed nesting site.
Musky odor in enclosed spaces
A persistent musky smell in cabinets, closets, or utility rooms — distinct from other household odors — is often caused by mouse urine marking their established travel routes.
Prevention Tips
Keep Mice Out for Good
Treatment eliminates the current infestation. These steps keep mice from returning. DND Pest Control will walk you through every one during your service visit.
Seal all gaps over ¼ inch
Use steel wool, hardware cloth, or caulk to seal any opening larger than a pencil eraser around pipes, vents, and foundation edges.
Clear vegetation from foundation
Shrubs, ivy, and dense groundcover against the foundation give mice shelter and a launching point. Keep a clear 12-inch gap around the perimeter.
Fix moisture & leaks
Mice are attracted to water sources. Repair leaky pipes, fix poor drainage near the foundation, and address condensation issues in crawl spaces.
Store food in sealed containers
Move dry goods from cardboard or thin plastic packaging into hard-sided sealed containers. Don't leave pet food out overnight.
Store firewood away from the home
Wood piles against the house are prime mouse habitat. Store firewood at least 20 feet from the foundation and elevated off the ground.
Schedule annual inspections
Proactive annual inspections catch new entry points and early activity before a full infestation develops — the most cost-effective mouse control strategy.
FAQs
Common Questions About Mice Treatment
How do I know if I have one mouse or many?
If you're seeing droppings in multiple areas, hearing sounds in more than one location, or spotting a mouse during daylight hours, you almost certainly have more than one. Mice rarely travel alone for long — where there's one, there's a colony nearby. Our inspection will give you a clear picture of the true scope.
How long does mice treatment take to work?
Initial results are typically seen within 3–7 days of treatment. Full elimination of an established infestation usually requires 2–3 service visits over 3–4 weeks to account for the reproductive cycle and to confirm all individuals have been removed.
Is the treatment safe for children and pets?
Yes. We use tamper-resistant bait stations that are inaccessible to children and pets. Snap trap placements are positioned in areas out of reach. We'll walk you through all safety precautions during the service visit and advise on any temporary precautions needed.
Can mice come back after treatment?
Without exclusion work to seal entry points, yes — new mice can re-enter from outside. That's why D&D's treatment always includes identifying and sealing access points, not just eliminating the current infestation. Exclusion is what separates a permanent solution from a temporary one.
Should I clean up mouse droppings myself?
Not without precautions. Never sweep or vacuum dry droppings — this aerosolizes particles that can carry Hantavirus. Droppings should be dampened with a disinfectant spray first, then removed with gloves and disposed of in a sealed bag. Our technicians can advise on safe cleanup procedures for your specific situation.
