Bat Removal in Old Lyme, CT – Humane Exclusion

---

 In Old Lyme, CT, bat removal must be performed by a licensed Nuisance Wildlife Control Operator (NWCO). At RF Wildlife, we use humane exclusion methods and full structural sealing to permanently solve bat problems.  Because most bat species in Connecticut are protected, it is illegal to kill bats or use poisons or chemicals.

Professional bat removal focuses on:

• Full home inspection 
• Identifying all entry points (some as small as 3/8 inch) 
• Installing one-way exclusion devices 
• Sealing the structure to prevent re-entry 

This process allows bats to leave safely while ensuring they cannot return.

Homes in Old Lyme often have:

• Older rooflines and soffits 
• Vent gaps and flashing issues 
• Seasonal occupancy (problems go unnoticed) 
• Wooded areas ideal for bat colonies 

Along the shoreline, weather and moisture wear down materials faster, creating the small openings bats use to enter homes.

Bat removal is not trapping—it’s a structural sealing process.

1. Inspection
   Every entry point is identified—not just the obvious one. 
2. Exclusion
   One-way devices allow bats to exit safely at night. 
3. Full Sealing
   All gaps are permanently sealed. 
4. Cleanup (if needed)
   Guano removal and attic sanitation when required. 

• Only one hole was sealed 
• Secondary gaps were missed 
• Work was done at the wrong time 

If even one gap is left open, bats will return.
 

• Maternity Season (No Exclusion): June 1 – Mid-August 
• Best Time for Removal: August – Mid-October 

Bat exclusion is not performed during winter hibernation. At this time, bats are dormant inside the structure. If the home is sealed, it changes airflow and internal conditions.

Instead of leaving, bats can wake up and move deeper into the home trying to survive—sometimes ending up in living spaces.

Sealing a home at the wrong time doesn’t solve the problem—it usually makes it worse.

If a bat was found:

• In a room with a sleeping person 
• Near a child or pet 

👉 Do NOT release it. It must be captured and tested.

Contact the local health department for guidance and rabies testing instructions.
For Old Lyme residents, you can contact the Ledge Light Health District at (860) 448-4882.

• Close interior doors 
• Open a window 
• Turn off lights 

The bat may leave on its own.

• Wear thick gloves 
• Wait for it to land 
• Cover with a container and slide cardboard underneath 

• Inspection: FREE 
• Single Bat Removal: $225+ 
• Full Exclusion: $500 – $1,500+ 
• Large Homes: $1,500 – $8,000+ 
• Guano Cleanup: $500 + 

Pricing is based on:

• Number of entry points 
• Roofline complexity 
• Difficulty of access (steep roofs, high peaks, tight areas) 
• Equipment needed (ladders, lift rental, boom lifts) 
• Level of guano contamination and insulation damage 

The biggest factor isn’t the number of bats—it’s how complex the structure is and how difficult it is to properly seal it.

Bat exclusion is a structural repair. Once sealed properly, bats cannot re-enter.

That’s why the warranty stays with the property—not just the homeowner.

Squeaking, scratching, droppings, staining, and bats flying at dusk are common signs.

Outside maternity season and not during winter hibernation.

Typically starts around $500 depending on the structure.

If there’s possible contact, it must be captured and tested.
