Bat Removal Old Saybrook CT | Done Right – Full Exclusion

---

In Old Saybrook, bat removal must be performed by a licensed Nuisance Wildlife Control Operator (NWCO) using humane exclusion methods. 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.

We’re based right here in Old Saybrook and work these homes every day.

This area has:

• Older homes with aging rooflines 
• Soffit and fascia gaps 
• Vent openings and flashing issues 
• Seasonal homes where problems go unnoticed 

On the shoreline, salt air and weather wear down materials faster—creating the exact kind of gaps bats use to get inside.

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

1. Inspection
   We locate every active and potential entry point—not just the obvious one. 
2. Exclusion
   One-way devices allow bats to exit safely at night. 
3. Full Sealing
   Every gap is sealed so they cannot get back in. 
4. Cleanup (if needed)
   Guano removal and attic restoration if contamination is present. 

Most repeat problems happen because:

• Only the main hole was sealed 
• Secondary entry points were missed 
• Work was done at the wrong time of year 

If even one gap is left open, bats will find it.
 

Bat removal is regulated to protect young bats:

• 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 is inside your home, what you do depends on possible contact.

If the 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 Connecticut Department of Energy and Environmental Protection for guidance.

• Close off interior rooms 
• Open a window or exterior door 
• 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 

Costs vary depending on the home and structure:

• Inspection: FREE 
• Single Bat Removal: $225 – $430 
• Full Bat Exclusion: $500 – $1,500+ 
• Large / Complex Homes: $1,500 – $8,000+ 
• Guano Cleanup & Restoration: $500 – $5,000+ 

• Number of entry points 
• Roofline complexity 
• Contamination level 

The biggest factor isn’t the number of bats—it’s how many places they can get in.
 

Bat exclusion is a structural repair, not a temporary fix. Once all entry points are properly sealed, bats cannot re-enter the home.

That’s why our warranty stays with the property itself—not just the current owner.

Whether you’re buying or selling a home in Connecticut, the protection remains in place.

We regularly get calls from homeowners who already had multiple companies out and still don’t have a clear answer.

In many cases, the problem isn’t just removal—it’s correct identification and proper sealing.

Getting it right the first time saves time, money, and repeat problems.

If you’re hearing:

• scratching 
• squeaking 
• or movement in your attic or walls 

It’s important to correctly identify the problem early.

Professional bat removal ensures the issue is handled:

• safely 
• legally 
• and permanently

Common signs include squeaking or scratching sounds, staining near rooflines or vents, bat droppings (guano), a strong attic odor, and bats exiting the home at dusk.

Bat exclusion is performed outside of maternity season using one-way devices and full sealing so bats can leave safely and not return. Exclusion is not performed during winter hibernation or between June and mid-August.

Bat exclusion in Old Saybrook typically starts around $500, with final pricing based on the structure, access, and number of entry points. Inspections are free.

If a bat is found in a room with a sleeping person, child, or pet, it must be safely captured and tested for rabies. If no contact occurred, isolate the room and allow the bat to exit. Never handle a bat with bare hands.
