Bat Removal and Exclusion in Brandon
Where bats get in on Brandon houses
Bats do not gnaw an opening. They use a gap the building already has, and an adult can fit through something close to three eighths of an inch wide. On the block and stucco houses that make up most of Brandon, that gap is at the soffit. Vented aluminum and vinyl panels sit in a J channel rather than being fixed along their length, so the ends lift as the fascia moves and the fasteners give up, and one lifted end is enough.
Ridge and gable vents are the other common way in once the insect screening behind them corrodes or tears. Both openings sit above head height and read as ordinary wear from the ground, which is why the first real evidence a homeowner gets is usually noise at dusk or a line of droppings on the wall below.
Food supply is why the building stays attractive after the colony has used it once. The oak canopy on the older streets and the water along the Alafia corridor to the south keep insect numbers up through the warm months, so a colony evicted from a building it can still get back into will simply return to it.
What exclusion means in practice
Exclusion works by making the building impossible to re enter rather than by killing anything. Every gap in the envelope is closed except the openings the colony is using. Those get one way doors, which let a bat drop out to feed and give it nothing to climb back through. Once the roost is empty the doors come off and the last openings are sealed for good.
The devices stay in place for several nights and the schedule follows the weather, because a cold night keeps bats in the roost. Florida guidance is to leave exclusion devices up for at least four nights with forecast overnight lows of fifty degrees or better, so that every animal in the colony gets a fair chance to leave.
The season the state sets
Florida protects bats all year and prohibits exclusion without appropriate authorization between April 16 and August 14, while the pups cannot yet fly. April 15 is the last day exclusion can be carried out without a permit, and the unpermitted window reopens on August 15. Exclusion devices stay in place for at least four nights with forecast overnight lows of at least fifty degrees. Sealing an occupied entry point inside that window traps the colony in the building, which is unlawful and leaves the structure far worse off than the bats did.
Closing an active entry point inside that period seals adults and pups into the structure. That is unlawful, and it turns a bat problem into a decomposition problem inside a ceiling or wall cavity. A closed season call still gets a full inspection, an entry point map and a quote, with the work booked for the day the window opens.
