Rodent Control in Connecticut & New York
Complete elimination of mice and rats through professional trapping, exclusion, and prevention. Protect your home from damage and disease.
Rodents are the most common pest problem in Connecticut and New York homes. Mice and rats enter structures seeking food, water, and shelter, especially during fall and winter. These destructive pests chew through wiring (fire hazard), contaminate food, spread diseases, and reproduce rapidly. A few mice can become an infestation in weeks. Professional rodent control requires species identification, comprehensive trapping, exclusion to seal entry points, and sanitation to eliminate attractants.
Common Rodents in CT & NY
House Mice
Norway Rats
Roof Rats
Signs of Rodent Infestation
💩 Droppings
Small dark droppings along walls, in cabinets, or near food—mice: rice-sized; rats: larger
🔊 Scratching Sounds
Scratching, scurrying, or squeaking in walls, ceilings, or attics—especially at night
🦷 Gnaw Marks
Chewed food packaging, wires, wood, or plastic—fresh marks are lighter colored
🟤 Grease Marks
Dark smudges along walls and baseboards where rodents travel repeatedly
🪹 Nests
Shredded paper, fabric, or insulation in hidden areas—cabinets, walls, attics
👃 Musky Odor
Strong musky smell from urine—especially noticeable in enclosed spaces
Our Rodent Control Process
Comprehensive three-step approach: eliminate, exclude, prevent.
Inspection
Identify rodent species, locate activity, and find entry points.
- Determine mice vs rats vs both
- Locate nesting areas and droppings
- Identify all entry points and gaps
- Assess infestation severity
Trapping & Elimination
Strategic trap placement for complete population removal.
- Snap traps in high-activity areas
- Multiple trap placements throughout structure
- Regular monitoring and trap servicing
- Continue until zero activity
Exclusion & Prevention
Seal entry points and eliminate attractants.
- Seal gaps with rodent-proof materials
- Install door sweeps and screens
- Sanitation and storage recommendations
- Follow-up monitoring
🔒 Why Exclusion is Non-Negotiable
Trapping eliminates current rodents, but new ones will enter if gaps remain open. Mice squeeze through 1/4 inch openings (the width of a pencil). Rats need only 1/2 inch. We seal all entry points with steel wool, hardware cloth, concrete, and metal flashing—materials rodents can't chew through. Common entry points include foundation cracks, gaps around pipes and wires, damaged vents, and spaces under doors. Without professional exclusion, you're just trapping the same problem over and over.
Rodent Control Questions
Rodents transmit numerous serious diseases:
- Hantavirus: Potentially fatal respiratory disease from urine/droppings
- Salmonella: Food poisoning from contaminated surfaces
- Leptospirosis: Bacterial infection from water contaminated with urine
- Rat-bite fever: Bacterial infection from bites or scratches
- Lymphocytic choriomeningitis: Viral infection affecting neurological system
- Plague: Rare but possible from fleas on rodents
- Parasites: Host fleas, mites, and ticks that spread to pets and people
Rodents multiply at alarming rates:
- Mice: 5-10 litters per year; 5-6 babies per litter = 25-60 offspring/year
- Sexual maturity: Mice at 6 weeks; rats at 3 months
- Gestation: Only 19-21 days (mice); 21-24 days (rats)
- Exponential growth: One female mouse → 60+ offspring → hundreds of descendants in months
- Year-round breeding: Indoors, rodents breed continuously
This is why early intervention is critical—small problems become infestations fast.
Rodent damage is extensive and costly:
- Electrical fires: Chewed wiring causes thousands of house fires annually
- Structural damage: Gnaw through wood, drywall, and insulation
- Plumbing damage: Chew through plastic pipes causing leaks
- Food contamination: Ruin stored food with droppings and urine
- Vehicle damage: Chew car wiring and nest in engines
- Insulation destruction: Compress and contaminate attic insulation
- HVAC damage: Nest in ductwork and damage systems
Timeline varies by infestation severity:
- Light (few mice): 1-2 weeks with proper trapping
- Moderate: 2-4 weeks with multiple trap visits
- Heavy infestation: 4-8 weeks requiring aggressive approach
- Exclusion work: Can be done during or after trapping
- Monitoring period: 2-4 weeks after last catch to confirm elimination
Complete control requires both trapping AND exclusion to seal entry points.
Prevention requires exclusion and sanitation:
- Seal all gaps larger than 1/4 inch with steel wool, hardware cloth, or concrete
- Install door sweeps on all exterior doors
- Cap chimneys and screen all vents
- Store food in rodent-proof metal or glass containers
- Keep garbage in sealed containers; empty regularly
- Don't leave pet food out overnight
- Remove yard debris and woodpiles from foundation
- Trim tree branches away from roof (6+ feet)
- Fix leaks and eliminate standing water
- Store firewood off ground and away from house
Rodent Prevention Tips
🔒 Seal Entry Points
Close all gaps larger than 1/4 inch with steel wool and caulk—mice squeeze through tiny openings.
🗑️ Secure Food & Garbage
Store food in sealed containers; use trash cans with tight lids emptied regularly.
🧹 Eliminate Clutter
Remove boxes, debris, and clutter where rodents hide and nest—especially in basements.
🚪 Install Door Sweeps
Ensure tight seals at bottom of all exterior doors—common rodent entry point.
🪵 Clear Yard Debris
Remove woodpiles, leaf piles, and dense vegetation from foundation—eliminates harborage.
🔍 Regular Inspections
Check for droppings, gnaw marks, and entry points monthly—early detection prevents infestations.
