BAT
EXCLUSION
SERVICES
Florida's bats are protected by state law - you cannot trap, kill, or exclude them during maternity season. David performs FWC-compliant humane exclusion with permanent sealing, attic sanitation, and a 1-year warranty.
The Problem
Bats in the Attic - Legal, Biological, and Health Considerations All Apply
Florida's 13 native bat species are protected by state law and are ecologically valuable - a single bat can consume hundreds of insects per night. But a colony in your attic is still a structural and health problem that requires professional resolution.
Bats roost colonially throughout the year in structures that provide the warmth and shelter they need - attics, soffits, wall voids, and behind shutters and siding. Southwest Florida's aging and hurricane-damaged rooflines provide particularly easy access; bats can enter through gaps as small as 3/8 of an inch at ridge vents, gable ends, soffit intersections, and where roofline materials separate. Over time, guano accumulates in the attic, carrying histoplasmosis - a fungal respiratory infection spread when dried guano is disturbed. Heavily contaminated attic insulation requires professional remediation, not just vacuuming.
The most critical point for Florida homeowners: you cannot legally trap or kill bats, and you cannot install exclusion devices during maternity season - April 16 through August 14 - when flightless pups are present in the roost. Attempting exclusion during this period traps pups inside, where they die and create an odor and pest problem. The legal window for exclusion is August 15 through April 15.
⛔ Never seal entry points without exclusion devices in place first. Sealing a bat entry point with the colony still inside traps the animals, which is an animal cruelty violation under Florida law regardless of intent. Exclusion devices must be installed first to allow the colony to exit, then entry points are permanently sealed after the colony has fully vacated.
- ✓Protected by State Law - All 13 Florida bat species are protected nongame wildlife. Trapping, killing, or excluding them during maternity season is illegal under Florida Administrative Code 68A-9.012.
- ✓Guano Health Risk - Accumulated bat guano in attic spaces carries Histoplasma capsulatum, a fungal pathogen that causes histoplasmosis when dried guano is disturbed. Professional remediation is recommended for any significant accumulation.
- ✓Rabies Risk - Bats are a documented rabies vector in Florida. Any direct contact between a bat and a person or pet - including a bat found in a bedroom - should be reported to the Florida Department of Health. The bat should not be released; it may need to be tested.
- ✓Structure Damage - Guano is acidic and degrades wood, insulation, and drywall over time. Urine staining on ceilings and walls is common in structures with long-term bat infestations.
- ✓Schedule Early - The first weeks after August 15 fill quickly across Sarasota and Manatee counties. An inspection done during maternity season lets David document entry points so work begins the day the legal window opens.
Florida Species
Bat Species Found in Sarasota & Manatee County Structures
Florida has 13 native bat species. Three are most commonly responsible for structural roost colonies in this region. One is federally endangered.
Brazilian Free-Tailed Bat
Tadarida brasiliensis
The most common structural bat in Florida. Medium-sized, dark brown to gray, with distinctively long narrow wings and a tail that extends well beyond the tail membrane. Forms the largest colonies - attic populations can run into the hundreds in a single structure. Fast fliers that forage widely, consuming massive quantities of mosquitoes and agricultural pests nightly. Their chattering vocalization is often the first sign of an attic colony.
Evening Bat
Nycticeius humeralis
Small, dark brown bat with a rounded tragus (the flap inside the ear) and short, rounded ears. The second most common structural bat in the region. Evening bat colonies in attics are typically smaller than Brazilian free-tailed bat colonies - usually under 50 individuals - but still require professional exclusion. They roost in tight clusters, often tucked behind fascia boards, in wall voids, or in attic spaces with warm microclimates.
Florida Bonneted Bat
Eumops floridanus
Florida's largest bat species and one of the rarest - listed as federally endangered under the Endangered Species Act. Occasionally found in Southwest Florida structures. If a Florida bonneted bat is identified or suspected during an inspection, both FWC and U.S. Fish & Wildlife Service involvement is required before any exclusion work proceeds. Any work involving this species follows a more formal regulatory process.
Florida Bat Law
The Legal Exclusion Window - and Why It Matters
Florida bat exclusion is governed by FWC under Florida Administrative Code 68A-9.012. The timing of your exclusion is not optional - it is legally defined.
Exclusion Is Legal
One-way exclusion devices may be installed during this period. Young bats from the previous maternity season are capable of flight and can exit the structure through the devices. This is the window David schedules all exclusion work. Devices must remain in place for a minimum of four nights, and only when overnight temperatures are forecast above 50°F.
Exclusion Is Illegal
Pups are born in mid-April and are flightless until late summer. Installing exclusion devices during this period traps flightless pups inside, resulting in their deaths - an animal cruelty violation under Florida law regardless of intent. No legitimate bat exclusion company will perform exclusion work during this window. An FWC permit is required for any exceptions, which are limited to specific public health circumstances.
What to do if you discover bats during maternity season: Contact David for an inspection. He can document every entry point, photograph evidence, and produce a written scope of work - so that exclusion begins the day August 15 arrives. Inspection is legal year-round. Only the installation of exclusion devices is restricted during maternity season.
David's Approach
FWC-Compliant Exclusion - Every Step
Bat exclusion has a specific legal sequence. Every step matters, and none of them can be skipped or rearranged.
Full Inspection
David inspects the structure inside and out to identify every bat entry and exit point, confirm species, estimate colony size, and document guano accumulation. Can be done year-round, including during maternity season.
Pre-Seal Inactive Gaps
All secondary and non-active gaps are permanently sealed before exclusion devices are installed. This funnels the colony through the controlled exits and ensures bats don't find a new way in while the primary exits are coned.
One-Way Exclusion
Professional one-way exclusion devices - cones or netting - are installed over active entry points. Bats can exit to forage but cannot re-enter. Devices remain in place a minimum of four nights to allow the full colony to exit.
Final Seal & Sanitation
Once the colony has fully vacated, exclusion devices are removed and entry points are permanently sealed. Attic guano is treated with Bac-A-Zap and DSV disinfectant. Bat houses are available for the displaced colony.
1-Year Warranty
Ratical's bat exclusion is backed by a 1-year warranty. If bats re-enter through any sealed point within a year of service, David returns to address it at no additional charge.
Why Ratical
FWC Compliance Is Not Optional - It's the Whole Job
A company that offers to exclude bats during April through August is offering to break Florida law. David performs bat exclusion only during the legal window - and documents every step.
Fully FWC-Compliant
David only performs bat exclusion between August 15 and April 15. Inspections are available year-round, but no exclusion devices are installed during the restricted maternity season window - period.
Attic Sanitation Included
Guano remediation with Bac-A-Zap and DSV disinfectant is included in the exclusion service. Bat guano carries histoplasmosis risk - professional sanitation is not optional for a complete job.
Bat Houses Available
A displaced bat colony doesn't disappear - it looks for a new roost site. Bat houses installed on the property give the colony an alternative, keeping them working as insect controllers without living in your attic.
You Always Reach David
