At Durand’s Bat Removal, we focus on solving bat problems correctly and for the long term. With years of hands on experience, our technicians take a structure wide, humane approach to bat exclusion. Below is a clear overview of what to expect when we work on your home.
Our Bat Exclusion Process
Step one: The Inspection
After you reach out, we schedule an inspection of your home. Homeowners are welcome to be present, but it is not required.
During the inspection, we:
Evaluate the exterior of the home and roofline
Identify potential entry and exit points
Look for signs of bat activity or colonies
Photograph and document key findings for your review
Inspect attic spaces when safely and easily accessible
At the conclusion of the inspection, we:
Review our findings with you
Explain any risks or concerns observed
Outline recommended next steps and exclusion options
Additional notes:
Most inspections are completed from the exterior of the home
A flat rate inspection fee applies for local properties
The inspection fee is credited toward the project total if you choose to move forward
Travel based adjustments may apply outside our standard service area
Step two: Bat Proofing & Entry Point Control
After identifying the bat entry and exit points, we begin bat proofing the structure while keeping primary exits temporarily open so bats can safely leave the home.
During this phase, we:
Seal all open gaps, seams, and vulnerabilities across the entire exterior, this is a very detailed process and the bulk of the work
Leave active exit points open until exclusion devices are in place
Use durable, professional grade materials including caulk, grout, wood, hardware cloth, wedges, and expanding foam
Focus heavily on rooflines, siding transitions, vents, and elevated areas
Ensure all materials used are paintable or stainable for a clean, finished appearance
Because bats will immediately search for alternative access once exclusion begins, addressing the entire structure is critical. Missing even one small opening can allow bats to relocate rather than leave, this is due to their instinctual nature.
Important notes:
Bats can enter openings as small as approximately 3/8 of an inch
Partial or limited scope work often leads to bats moving to a different area of the home
Full home bat proofing provides the most reliable, long term results
Our goal is always to solve the problem completely while maintaining the appearance and integrity of your home.
Step Three: One Way Exclusion and Monitoring
Once the home has been fully bat proofed, we install one way exclusion devices over the primary entry and exit points. These devices allow bats to leave the home safely but prevent them from getting back inside.
During this phase, we:
Install professional temporary one way exclusion devices at confirmed access points
Ensure all other openings across the structure are fully sealed
Use methods appropriate to the structure and entry location
Monitor bat activity to confirm successful exit from the home
Bats may take several nights to fully exit, especially during periods of poor weather. This monitoring period allows us to confirm that all bats have safely left before final sealing is completed. This usually takes about 1 weeks time.
Step Four: Final Sealing and Completion
Once we confirm that all bat activity has stopped, we remove the exclusion devices and permanently seal the remaining access points.
This final step:
Prevents bats from re entering the structure
Ensures no bats are trapped inside the home
Completes the exclusion process safely and humanely
After completion, we recommend homeowners remain observant for a short period, as bats may explore the structure before fully moving on. This behavior is normal and does not indicate a failure when full home exclusion has been completed properly.

“Neal instills confidence from the initial visit. We contacted him to check for bat activity and possible infestation. He was able to locate the entry points and then followed up with a number of solutions to safely prevent the bats from re-entering our home. He is very courteous and cleaned up after himself. Highly recommend his services!”
