Rat Control in Connecticut & New York
Complete rat elimination with trapping, exclusion, and prevention. Protect your home from disease-carrying rodents.
Rats are serious pests in Connecticut and New York, causing structural damage, contaminating food, and spreading diseases. These intelligent rodents reproduce rapidly and can squeeze through openings as small as 1/2 inch. Rats chew through wiring (fire hazard), insulation, and building materials while leaving droppings and urine throughout structures. Professional rat control requires trapping, exclusion to seal entry points, and sanitation to eliminate attractants.
Common Rat Species in CT & NY
Norway Rats
Most common—burrow underground
- Brown/gray fur; heavy, stocky body
- Up to 16 inches (body + tail)
- Burrow along foundations and under debris
- Live in basements, crawl spaces, sewers
- Excellent swimmers; enter through toilets/drains
Roof Rats
Agile climbers—nest in attics
- Black or dark brown; sleek, slender body
- Up to 16 inches (body + tail)
- Excellent climbers; travel on power lines
- Nest in attics, trees, upper levels
- Less common in CT/NY but increasing
Key Differences
Identification helps target control
- Norway: Blunt nose, small ears, thick tail
- Roof: Pointed nose, large ears, thin tail
- Norway: Ground level/basements
- Roof: Upper levels/attics
- Both require professional elimination
Signs of Rat Infestation
💩 Droppings
Large capsule-shaped droppings (3/4 inch)—found along travel routes and near nests
🔊 Scratching Sounds
Scratching, scurrying, or squeaking in walls, ceilings, or under floors at night
🟤 Grease Marks
Dark smudge marks along walls where rats travel—from oils on their fur
🦷 Gnaw Marks
Chewed wood, wires, plastic, or food packaging—fresh marks are lighter colored
🕳️ Burrows
Holes along foundations, under debris, or in landscaping (Norway rats)
👃 Musky Odor
Strong, musky smell from urine—especially noticeable in enclosed spaces
Our Rat Control Process
Comprehensive elimination through trapping, exclusion, and sanitation.
Inspection
Identify rat species, locate nests, and find entry points.
- Determine Norway vs roof rat
- Locate nesting areas and travel routes
- Identify all entry points and gaps
- Assess population size and activity level
Trapping Program
Strategic trap placement for rapid population reduction.
- Snap traps in high-activity areas
- Bait stations in protected locations
- Regular monitoring and trap servicing
- Multiple visits until elimination
Exclusion & Prevention
Seal entry points to prevent re-infestation.
- Seal gaps larger than 1/4 inch
- Install door sweeps and screens
- Repair foundation cracks
- Sanitation and storage recommendations
🔒 Exclusion is Essential for Permanent Control
Trapping eliminates existing rats, but without exclusion they'll simply return. Rats squeeze through gaps as small as 1/2 inch. We seal all entry points with rodent-proof materials—steel wool, hardware cloth, concrete, metal flashing. Common entry points include foundation cracks, gaps around pipes and utilities, damaged vents, and spaces under doors. Long-term rat control requires both elimination AND prevention through professional exclusion work.
Rat Control Questions
Rats pose serious health and safety risks:
- Disease transmission: Carry leptospirosis, hantavirus, salmonella, rat-bite fever, plague
- Parasites: Host fleas, mites, and ticks that spread to people and pets
- Fire hazard: Chew electrical wiring creating fire risk
- Structural damage: Gnaw through wood, insulation, pipes, and building materials
- Contamination: Urine and droppings contaminate food and surfaces
- Bites: Can bite if cornered, especially when protecting young
Rats enter through surprisingly small openings:
- Foundation gaps: Cracks and holes in foundation or basement walls
- Utility penetrations: Gaps around pipes, wires, and cables
- Vents: Uncapped chimneys, damaged foundation vents, roof vents
- Doors: Gaps under doors without proper sweeps
- Roof access: Gaps in soffits, eaves, or where roof meets walls
- Drainage: Through floor drains, sewer lines, or damaged pipes
Rats can squeeze through openings as small as 1/2 inch (size of a quarter).
Rat elimination timeline varies by infestation severity:
- Light infestation: 1-2 weeks with proper trapping
- Moderate: 2-4 weeks with multiple trap visits
- Heavy: 4-6+ weeks requiring aggressive approach
- Exclusion: Can be done during or after trapping
- Monitoring: Follow-up visits ensure complete elimination
Success requires both elimination AND exclusion to prevent re-entry.
We prefer traps for several important reasons:
- Traps: Allow us to remove dead rats preventing odor and secondary pest issues
- Poison risks: Rats can die in walls creating terrible smell; takes weeks to locate
- Pet safety: Traps pose no risk to pets or children
- Confirmation: Traps confirm elimination; poison leaves uncertainty
- Faster: Properly placed traps work within days
We use bait stations only in specific situations where traps aren't practical.
Prevention requires exclusion and sanitation:
- Seal all gaps larger than 1/4 inch with rodent-proof materials
- Install door sweeps on all exterior doors
- Cap chimneys and screen all vents
- Store garbage in sealed containers; empty frequently
- Don't leave pet food out overnight
- Remove yard debris, woodpiles, and dense vegetation near foundation
- Trim tree branches away from roof
- Fix plumbing leaks and drainage issues
- Store food in rodent-proof containers
Rat Prevention Tips
🔒 Seal All Entry Points
Close gaps larger than 1/4 inch with steel wool, hardware cloth, or concrete—rats can't chew through.
🗑️ Secure Garbage
Use sealed trash cans with tight lids; don't leave garbage bags accessible overnight.
🧹 Remove Clutter
Clear yard debris, woodpiles, and dense vegetation near foundation—eliminates rat harborage.
🚪 Install Door Sweeps
Ensure tight seals at bottom of all exterior doors—common rat entry point.
🍲 Don't Feed Rats
Store pet food in sealed containers; don't leave food bowls out overnight.
🌳 Trim Trees
Keep branches 6+ feet from roof—prevents roof rat access to upper levels.
