Bat Exclusion

Professional Bat Exclusion

United Bat Control has specialized in professional bat removal and bat exclusion nationwide since 1998.

Bat exclusion is the process of removing bats from a building humanely and addressing the openings that allow them to enter.

The goal is not simply to get bats out. A successful exclusion also requires identifying how the bats are using the structure, allowing them to leave safely, and helping prevent them from returning.

United Bat Control provides bat exclusion for residential, commercial, industrial, educational and healthcare properties throughout the United States.

Professional bat inspection and exclusion

A Complete Building Inspection Comes First

One of the first steps in professional bat exclusion is a careful inspection of the entire structure.

Attention to detail is critical. Bats can use very small openings, and a successful inspection must identify both the locations they are actively using and other openings that could allow them to enter the building.

Potential bat entry points may include:

  • Rooflines and roof edges
  • Eaves and soffits
  • Roof valleys
  • Gable areas
  • Chimneys
  • Roof and attic vents
  • Dormers
  • Siding gaps
  • Wall and construction joints
  • Openings around utility lines and cables
  • Heating and air-conditioning penetrations
  • Other cracks, gaps and structural openings

Look for Signs of Bat Activity

In addition to locating openings in the structure, an inspection should look for evidence that bats are actively using the building.

Common signs may include:

  • Bat guano beneath entry points or roosting areas
  • Dark or stained areas around heavily used openings
  • Bat activity near the roofline around dusk
  • Sounds or movement inside attics, walls or ceilings
  • Bats repeatedly entering occupied portions of the building
  • A visible group of bats leaving the structure in the evening

These signs can help identify where the bats are roosting and how they are moving through the structure.

Attic & Interior Inspection

Where accessible and appropriate, attic and interior areas may also need to be inspected for signs of bat activity.

An attic inspection can help identify colony location, guano accumulation, interior travel paths and possible entry areas that may not be obvious from the exterior of the building.

Because bat guano and contaminated areas can present health concerns, inspection and cleanup should be approached carefully and with appropriate protective equipment.

Dusk Observation Can Reveal Active Entry Points

Bats commonly leave their roost around dusk to feed. Observing the building during this period can help confirm active entry and exit points that may have been difficult to identify during a daytime inspection.

This information is useful in determining where exclusion methods should be placed and which openings require attention.

How Bat Exclusion Works

1. Identify Active Openings

The building is inspected to determine where bats are actively entering and leaving and where additional openings may exist.

2. Seal Unused Openings

Potential openings that are not being used for active bat exit can be sealed as appropriate so bats cannot simply move to another part of the structure.

3. Install One-Way Exclusion Devices

Appropriate one-way exclusion devices or methods are installed at active exit points. These are designed to allow bats to leave the building while preventing them from re-entering through the same opening.

4. Allow the Colony to Leave

The exclusion process allows the bats to leave the structure naturally. The timing and duration can vary depending on the colony, building and local conditions.

5. Permanently Seal the Structure

After the bats have been excluded, the remaining active openings are sealed as appropriate to help prevent re-entry.

6. Follow-Up

The completed work is reviewed and any remaining structural conditions can be addressed based on the property and scope of the project.

Why Bat-Proofing Is So Important

Removing bats without correcting the openings they use may not solve the problem.

Bat-proofing is the structural part of the exclusion process. It involves identifying and sealing cracks, gaps and other openings that could allow bats to return to the building.

United Bat Control evaluates the structure as a whole rather than simply addressing the most obvious opening.

Humane Bat Removal

Bats are an important part of the environment. They consume large numbers of insects and play a valuable role in many ecosystems.

The purpose of professional bat exclusion is to separate bats from people and buildings without unnecessarily harming the animals.

Our objective is to protect the people and property inside the structure while allowing bats to continue their role in the environment outside the building.

Bat Guano Cleanup

Bat colonies can leave accumulations of guano in attics, walls, ceilings, roof spaces and other areas of a structure.

Depending on the amount and location of the material, cleanup may require appropriate protective equipment and professional procedures.

When required by the condition of the property and scope of work, United Bat Control services may include guano removal, sanitation, odor control and related remediation.

Residential & Commercial Bat Exclusion

The fundamentals of bat exclusion apply to both homes and commercial buildings, but larger structures can present additional challenges.

Warehouses, industrial facilities, schools, hospitals, apartment buildings and other large properties may contain many roof levels, vents, structural joints and elevated areas that require a more detailed inspection and exclusion plan.

United Bat Control provides bat exclusion for both residential and commercial properties nationwide.

Warranty Coverage

Warranty coverage is available on qualifying bat-exclusion projects. Specific warranty terms are provided with each proposal based on the property, building conditions and scope of work.
