Professional Bat Exclusion Services Serving Burlington, Camden, Gloucester, and Mercer Counties
Finding bats in your attic, wall voids, or chimney is a complex and costly issue. Beyond being a public health concern, bat removal in New Jersey is subject to strict legal mandates that require a precise, professional sequence—a process DIY attempts often get wrong, making the problem worse and more expensive to fix.
New Jersey is home to nine bat species, all of which are protected under state law. The state’s two most common structure-dwelling species—the little brown bat (Myotis lucifugus) and the big brown bat (Eptesicus fuscus)—form maternity colonies in attics and wall voids from May through August, when females give birth and raise non-flying young.
New Jersey law prohibits exclusion during this window because sealing entry points while juveniles are present traps non-flying bats inside, causing mortality and creating a separate health and odor problem that is more expensive to resolve.
The most effective and legally compliant method for permanent bat removal is properly timed exclusion from The Pest Rangers. This precise, multi-step process begins with the installation of one-way devices during the active season, allowing bats to exit without re-entering.
Once the colony has vacated, the structure is fully sealed, and a professional attic decontamination is performed to remove guano and urine that could attract future infestations.
The Public Health Dimension of Bat Infestations in New Jersey
Beyond the legal complications of dealing with bats in your home, they can also be hazardous to your health and the structure of your home.
- Rabies Exposure: As the primary wildlife reservoir for rabies in New Jersey, bats found in living spaces or near sleeping individuals require immediate medical assessment and potential testing.
- Histoplasmosis: Large deposits of bat guano can harbor fungal pathogens that, when disturbed, cause serious respiratory disease.
- Structural Damage: Years of guano accumulation can saturate insulation, corrode metal components, and cause ceiling failure, often resulting in remediation costs of $5,000 to $15,000.
- Persistent Odors: Ammonia from urine and guano can permeate HVAC systems, creating a long-term health and comfort issue in the home.
Not only does bat exclusion safely remove existing bats from your property, but it also prevents them from returning, so you never have to worry about the problem again.
Guaranteed Bat Exclusion Process for South Jersey Homes
The Pest Rangers utilizes a rigorous, four-phase exclusion process designed to humanely remove colonies and permanently fortify your home against future infestations.
- Phase 1: Inspection and Assessment: We conduct a comprehensive exterior and interior evaluation to identify all active entry points and document the extent of colony growth and structural damage.
- Phase 2: Exclusion Device Installation: During the legal active season, we install one-way tubes or netting that allow bats to exit for nightly foraging, while blocking their return, clearing the structure within two weeks.
- Phase 3: Final Sealing and Removal: Once we confirm the colony has vacated, we remove all devices and permanently seal primary entry points using professional-grade materials to ensure no gaps larger than 6mm remain.
- Phase 4: Remediation and Decontamination: Our team performs a deep clean using HEPA-filtered equipment to remove hazardous guano and applies enzyme-based decontaminants to neutralize pheromones that could attract new bats.

Frequently Asked Questions
Is it legal to kill bats in New Jersey?
No. All nine bat species in New Jersey are protected under the New Jersey Endangered and Nongame Species Conservation Act. Lethal control is prohibited.
The only legal method is exclusion, which involves allowing bats to exit the structure and then permanently sealing entry points to prevent re-entry. Exclusion must not be performed during the May through August maternity season when non-flying juveniles are present.
Can I seal my attic to get rid of bats myself?
Sealing without first completing a proper exclusion or sealing during the maternity season traps bats inside the structure. Trapped bats will attempt to find alternate exit routes, which frequently means entering living spaces through interior openings.
Trapped and dying bats increase rabies exposure risk and create an odor problem that is more difficult and expensive to resolve than the original colony. Exclusion must be sequenced correctly to be both legal and effective.
When is the best time to do bat exclusion in South Jersey?
The legal and effective exclusion window in New Jersey is September 1 through April 15. This window falls between the end of the maternity season (when juveniles are flight-capable) and the beginning of the next.
Spring exclusions should be completed by early April, before pregnant females return to established roost sites. Fall is the ideal time because populations are at their post-pup peak, and conditions allow full confirmation that the colony has vacated before winter sealing.
How do bats get into South Jersey homes?
Little brown bats can squeeze through gaps as small as 6mm, which is about the diameter of a dime. In South Jersey residential housing, the most common entry points are gaps around chimney caps and flashing, deteriorated ridge vent covers, open soffit returns at the eave-to-wall junction, gaps in fascia boards at the roofline, and missing or damaged gable vents.
Older homes with original wood construction and homes that have had roofing or siding work done without attention to bat-exclusion implications are most frequently affected.
Will bats come back after exclusion?
Properly completed exclusion, which includes full structural sealing combined with guano remediation to remove pheromone markers, prevents the same colony from reestablishing in the same structure.
Bats do attempt to return to established roost sites, which is why the decontamination phase is essential. Residual urine pheromones in an undecontaminated attic signal to bats from outside that the roost is active, even after the physical entry points have been sealed.
