# Bat Exclusion in Seminole County, FL Source: https://drcritter.com/bat-exclusion/seminole-county-fl/ Type: Local service page Service: Bat Exclusion Area served: Seminole County, FL --- Professional Bat Exclusion services in Seminole County, FL. Dr. Critter specializes in protected species requiring specialized exclusion methods and provides expert wildlife control throughout Central Florida. **Bat exclusion in Seminole County, Florida — what you need to know:** Florida law (FAC 68A-9.010) prohibits bat exclusion from April 16 through August 14, the maternity season when flightless pups depend on the adult colony. Exclusion work must be scheduled for the late-August to early-April window. The correct method is a one-way exclusion device installed at every entry point of 3/8 inch or larger; this lets adult bats fly out at dusk but prevents re-entry. Devices stay in place 5–7 nights to ensure the entire colony has exited before permanent sealing. After the colony is out, accumulated guano must be remediated by trained technicians because dried guano can carry *Histoplasma capsulatum*, the fungus that causes histoplasmosis. Attempting bat removal during maternity season, or sealing entry points before the colony has fully exited, is both illegal and likely to kill the pups. **Wildlife in Seminole County:** Seminole County stretches from suburban Orlando north to the St. Johns River, mixing mature tree canopy with extensive wetlands. Squirrels and raccoons drive most attic calls, while the river basin and county wetlands keep snake activity high near the water. **Florida wildlife facts & law:** According to the [Florida Fish and Wildlife Conservation Commission](https://myfwc.com/conservation/you-conserve/wildlife/bats/bats-in-buildings/), all 13 of the state's native bat species are protected, bat maternity season runs April 16 through August 14, and Florida Administrative Code 68A-9.010 makes exclusion during that window illegal. April 15 is the last day a building can be cleared without a permit, and the work cannot resume until August 15. The same rule governs how: FWC requires an exclusion device to stay up a minimum of four nights, and the work to be done when overnight temperatures are forecast to reach at least 50°F, so the colony can actually leave. According to [University of Florida IFAS Extension](https://ask.ifas.ufl.edu/topics/rodents), a roof rat female produces litters of five to eight pups after a gestation of only 21 to 23 days and can raise four or five litters a year, which is how one unsealed roofline gap becomes 20 to 40 rats inside twelve months. UF/IFAS also reports that the nine-banded armadillo, the only armadillo species in Florida, gives birth to four genetically identical young per litter, so one breeding pair is enough to leave an entire yard pocked with digging. On snakes, UF/IFAS puts Florida at roughly 50 native species of which only six are venomous, and records that just four of those six occur in central and southern Florida: the eastern diamondback rattlesnake, the pygmy rattlesnake, the cottonmouth, and the harlequin coral snake. So most of what turns up beside a pool deck here is harmless, and under FAC 68A-4.001 it is protected too. Because raccoons and bats are the state's principal rabies-vector species, FWC rule 68A-9.010 sets what may lawfully happen to one once it is caught, and the list is shorter than people expect: released on the capture property when the capture and release sites are one contiguous piece of land, released off site only if the animal is native and the receiving property is inside the county of capture, is at least 40 contiguous acres, and its owner's written permission is in hand at the moment of release, or euthanized humanely. Whichever it is, it happens within 24 hours of the capture or of the trap being checked. Relocating the animal to a park or a patch of woods is on none of those lists.

Under Florida Administrative Code **68A-9.010**, exclusion or removal of bats is prohibited from **April 16 through August 14** — the maternity season. During this window, flightless pups are still in the roost; an exclusion that locks adults out leaves pups behind to starve, which is illegal and inhumane. The Florida Fish and Wildlife Conservation Commission (FWC) is the enforcing authority. If you discover bats in your Seminole County attic between mid-April and mid-August, the legal options are limited to monitoring and planning the work for late August.

Most Central Florida bats are Brazilian Free-Tailed Bats or Evening Bats; both are protected. - **Entry point identification** — Bats can squeeze through gaps as small as 3/8 inch. We inspect roof junctions, soffit gaps, ridge vents, gable louvers, dormer flashing, and chimney caps. - **One-way exclusion device installation** — Funnels or netting installed at every active entry, leaving an 18-inch downward-facing exit. Bats can fly out at dusk; they cannot fly back in. - **5–7 night exclusion window** — Devices remain in place long enough for every bat (including stragglers) to leave. Removing them too early traps animals inside. - **Permanent sealing** — Once the colony has fully exited, devices are removed and every entry point is sealed with copper mesh, polyurethane foam, or matched flashing. ### What Happens After Exclusion (Guano Remediation) Bat guano accumulates over years and carries *Histoplasma capsulatum*, a fungus that causes **histoplasmosis** — a lung infection that can be serious in people with compromised immune systems. Disturbed guano releases fungal spores into the air. After the bats are out, our technicians use HEPA-filtered respirators, Tyvek suits, and EPA-registered antimicrobials to remove guano, treat the substrate, and replace contaminated insulation. We do **not** recommend DIY guano removal for any deposit larger than a small flashlight beam — the airborne risk is real. ### Get Professional Help Today Don't let bats damage your Seminole County property.
