I only saw one mouse. Do I have an infestation?

Almost certainly yes. Mice are shy, nocturnal, and expert hiders. If you see one mouse during daylight hours, there are likely dozens more hiding in your walls, attic, or basement. A single pair of mice can produce 150 offspring in a year.

How do mice get into my house?

Mice can squeeze through gaps as small as a dime (about 1/4 inch). They enter through gaps around pipes, utility penetrations, foundation cracks, gaps around doors and windows, and even through dryer vents. Mice are motivated to enter in fall when temperatures drop.

Yes. Mice can transmit hantavirus, salmonella, leptospirosis, and lymphocytic choriomeningitis virus. Their droppings and urine contaminate food preparation areas. They also cause property damage and fire hazards from chewed wiring.

What is the best way to get rid of mice permanently?

The only permanent solution is exclusion — finding and sealing every entry point in your home. Trapping and baiting without exclusion will control the current population but new mice will enter within weeks. Exclusion, combined with elimination of the current population, is the only permanent fix.

Do mice come back after treatment?

Not if exclusion is done properly. If mice return after treatment, it means entry points were missed. We guarantee our exclusion work — if mice return through a point we sealed, we will fix it at no charge.

Why Mousetraps Alone Don't Work

Hardware store traps catch mice — temporarily. But until you seal the entry points, new mice will keep coming in from outside. Most homes have dozens of potential entry points that are invisible unless you know what to look for.

The Exclusion-First Approach

We inspect the entire exterior of your home, identify every gap and crack a mouse could use, and seal them with materials that cannot be chewed through. Then we eliminate the mice already inside. This is the only approach that works long-term.

House Mouse vs. Deer Mouse: Why It Matters

Not all mice are the same. The species you have changes the health risk profile and the treatment approach.

🏠 House Mouse (Mus musculus)

Appearance: Gray-brown with lighter underside, pointed snout
Size: 2.5–3.75 inches body, 0.5–1 oz
Habitat: Strictly commensal — lives inside structures year-round
Behavior: Inquisitive, explores new objects — responds well to snap traps
Disease risk: Salmonella, leptospirosis, lymphocytic choriomeningitis virus (LCMV)
Most common in: All NY residential and commercial structures

🌲 Deer Mouse (Peromyscus maniculatus)

Appearance: Brown with white underside and feet, large eyes and ears
Size: 3–4 inches body, slightly larger than house mouse
Habitat: Rural areas, wooded suburbs, cabins, seasonal homes
Behavior: Cautious of new objects — snap traps less effective initially
Disease risk: Primary carrier of Hantavirus Pulmonary Syndrome (HPS) — potentially fatal
Most common in: Long Island rural areas, Westchester, Hudson Valley properties

⚠️ Hantavirus Warning: Never vacuum or sweep deer mouse droppings dry. Disturbing droppings aerosolizes the virus. Call a professional for safe cleanup using proper PPE and disinfection protocol.

Entry Point Sealing: The Critical Step

A mouse can squeeze through any gap larger than 1/4 inch. Sealing every possible entry point in an older New York home is a systematic process — not something that can be done with a tube of caulk from the hardware store.

Pipe penetrations

Gaps around utility pipes entering walls and floors are among the most common entry points. We seal with copper mesh and professional-grade sealant.

Foundation gaps

Cracks in concrete block foundations, gaps where siding meets the foundation, and sill plate gaps are sealed with appropriate masonry or foam products.

Door sweeps & thresholds

Gaps under exterior doors larger than 1/4 inch are entry highways. We assess and recommend appropriate threshold or sweep solutions.

Utility entries

Dryer vents, exhaust vents, and utility penetrations are sealed with hardware cloth and properly screened to prevent entry while maintaining function.

Snap Traps vs. Rodenticide Bait: What We Use and Why

Both methods have their place. Here's how we decide which to use:

🪤 Snap Traps

Best for: Interior use, homes with pets/children, confirming species
Advantages: Instant kill, no secondary poisoning risk, confirms catch
Placement: Along walls and runways where mouse activity is visible
For house mice: Highly effective — house mice are curious and explore traps readily
For deer mice: May require pre-baiting period before triggering

☠️ Rodenticide Bait

Best for: Large infestations, inaccessible wall voids, exterior perimeter
Advantages: Effective for large populations; mice die in walls reducing ongoing captures
Requirements: Tamper-resistant bait stations required; NYS DEC compliant products only
Limitations: Secondary poisoning risk for pets and raptors if used improperly
Never used: In attics where deer mice may be present without proper containment
