Wildlife does not arrive in Central Florida homes at random. It arrives on a schedule set by breeding cycles, rainfall and temperature, and one of the busiest windows of the year is also the one window when the law forbids touching a bat colony. This calendar sets out which animals get into houses in which months across the seven counties we cover, what the state rules permit in each window, and what a homeowner can actually do when the answer is "not yet."

Two things it is not. It is not a forecast, and it is not a count. See methodology for exactly where each statement comes from and what we deliberately have not quantified.

How to read this calendar

Seasonal activity here is described in plain terms, busy or quiet, rather than as percentages. The regulatory dates are different: those are exact, they come from Florida Administrative Code, and they are the parts of this page worth writing down. Where a month carries a legal constraint, it is flagged in the season section and explained in full under bat maternity season.

Species names link to a full reference page. Counties link to local service pages where the habitat notes are specific to that area.

Spring, March to May

Spring is the heaviest attic season in Central Florida, and the reason is litters rather than weather.Raccoons breed from January through March, so females are looking for a dry, defensible space to move young into from March onward, which is why raccoon attic calls climb through spring and stay high into June. This is the hardest case to handle correctly: a female with kits cannot simply be excluded, because sealing the entry traps the young inside and the mother will open a second hole trying to reach them. The kits have to be located and removed by hand first. Squirrels are active in the same months and chew year round, and their damage to wiring is the one that carries a fire risk rather than a cleanup bill.

Spring is also when the bat rules start to matter. April 16 is the first day of the maternity season, and April 15 is the last day a building can be cleared before it closes.

Summer, June to August

Summer is when the calendar and the law collide. The entire month range from mid-April to mid-August sits inside the bat maternity season, so a homeowner who discovers a colony in June cannot legally have it excluded, whatever an operator offers. Meanwhile the summer rains push snakes toward higher, drier ground, which in a subdivision means garages, pool decks and screened enclosures. According to the Florida Fish and Wildlife Conservation Commission, Florida holds roughly 50 native snake species and only six are venomous, so most of what turns up beside a pool deck is both harmless and protected. Armadillo digging is heavy through the wet months because saturated soil is easier to work and holds more of the grubs they are after.

Fall, September to November

Fall is the repair window, and the one most homeowners waste. August 15 is the first day bat exclusion becomes legal again, and the weeks after it are the right time to do the work: the pups can fly, the colony can leave, and overnight temperatures are still well above the minimum the state requires for an exclusion to be valid. It is also when the animals that used a roofline in spring come back to the same opening, because an unsealed gap does not care what season it is. Reopened entry points from earlier in the year are the most common thing we find on a fall inspection.

Winter, December to February

Cooler nights move rodents indoors, and they do not need long to become a bigger problem. Roof rats breed year round in this climate rather than pausing for winter. According to University of Florida IFAS Extension, a roof rat female carries a litter of five to eight pups after a gestation of only 21 to 23 days and can raise four or five litters in a year. That is the arithmetic that turns one unsealed roofline gap into a serious infestation inside twelve months, and it is why a December rat call is not a smaller job than a June one. Raccoon breeding begins again in January, which starts the whole cycle over. Opossums arrive on the weather rather than on a breeding cycle: they do not hibernate, they shelter, so it is a cold snap and not a season that pushes one under a deck or into a soffit, which is why opossums in Central Florida attics are usually a December to February call rather than a spring one.

Central Florida wildlife activity by season, and the constraint that applies
Season	Most active in homes	What governs the work
Mar to May	Raccoons moving litters into attics; squirrels chewing	Bat exclusion closes April 16
Jun to Aug	Snakes displaced by rain; armadillo digging in wet soil	Bat exclusion prohibited all season
Sep to Nov	Re-entry through openings used in spring	Bat exclusion legal again from August 15
Dec to Feb	Roof rats and mice moving in as nights cool; opossums sheltering from cold snaps	No seasonal closure; disposition rules always apply

Bat maternity season, and why exclusion is illegal from April 16 to August 14

Florida prohibits bat exclusion from April 16 through August 14 under Florida Administrative Code 68A-9.010. During that window the roost holds flightless pups. An exclusion seals the building while the adults are out feeding, so doing it in the maternity season shuts the pups in to die while the mothers are locked out. That is the reason for the rule, and it is enforced by the Florida Fish and Wildlife Conservation Commission. Florida has 13 native bat species, harming them is unlawful, and capturing and relocating a colony is prohibited outright, so exclusion outside the closed window is the only lawful way to get bats out of a building. The FWC also sets how the work is done: an exclusion device has to stay in place for at least four nights, and those nights must be ones where the overnight temperature is forecast to reach at least 50°F, so the colony can actually leave rather than being sealed in by cold weather.

The practical consequences are worth stating plainly. April 15 is the last day a building can be cleared before the season closes, and August 15 is the first day the work can resume. A company offering to exclude bats in June is describing something the state does not allow. If you are told otherwise, that is a reason to call somebody else, and our bat reference page covers the biology and the rule in more detail.

County-by-county differences

The seven counties we cover do not produce the same call mix, because the habitat behind the houses is different.

Seminole and Orange: mature tree canopy and a dense network of retention ponds. Squirrels and raccoons drive most attic work, and snakes appear near the water features. See Seminole County and Orange County.
Volusia: the St. Johns River basin and coastal marsh. Raccoons, roof rats and bats in older beachside and mainland structures. See Volusia County.
Osceola: Lake Tohopekaliga and a broad band of marshland, so raccoons, opossums and snakes near the wetland edges. See Osceola County.
Polk and Highlands: the Lake Wales Ridge, with scrub and hammock country. A noticeably different mix, weighted toward armadillo and snake rather than attic rat. See Polk County and Highlands County.
Brevard: barrier island and lagoon edges, with raccoon and snake pressure close to the water. See Brevard County.

What to do if you are inside a blocked window

If you have bats and it is June, the honest answer is that the exclusion has to wait until August 15. That does not mean doing nothing for two months.

Confirm the species and the roost location now. An inspection during the closed season is legal and useful, and it means the work can be scheduled for the first days it becomes lawful rather than queued behind everyone else who waited.
Deal with the guano, not the colony. Bat guano carries Histoplasma capsulatum, the fungus behind histoplasmosis, and disturbed guano puts spores in the air. Remediation of accessible areas can proceed while the roost is left alone.
Seal everything that is not the roost exit. Secondary gaps can be closed during the season, which shrinks the job in August and stops a second species moving in.
Do not let anyone seal the roost. This is the one thing that turns a wildlife problem into a legal one and a dead-animal problem at the same time.

For raccoons the equivalent constraint is not a date but a litter. If kits are present, the young have to be removed by hand before the entry is sealed, and rushing that step is what produces a dead-animal call three weeks later. Raccoons are also one of Florida's principal rabies vector species, along with bats, which is why the state requires nuisance wildlife to be handled by the property owner or a licensed trapper.

What happens to an animal after it is caught

This is the part homeowners are most often misled about. Under FWC rule 68A-9.010, a live-captured nuisance animal has a short list of lawful outcomes: release on the property where it was caught, transfer to a licensed facility, or humane euthanasia. Driving it out to the country and letting it go is not among them.

Armadillos sit slightly differently, because they are non-native and not a protected species. FWC classifies the nine-banded armadillo as non-native and non-protected, nuisance removal is permitted year round without a permit, and a live-captured animal must be euthanized, released on site, or released within the same county on a property of 40 acres or more with the written permission of the landowner. UF/IFAS notes that the nine-banded armadillo, the only armadillo species in Florida, gives birth to four genetically identical young per litter, which is why a single breeding pair can leave an entire yard pocked with digging.

One more figure worth keeping, because it changes what cleanup means rather than what removal means. Raccoon latrines can carry Baylisascaris procyonis. The Companion Animal Parasite Council puts the eggs at a minimum of 10 to 14 days in the environment before they reach the infective stage, after which they are "hardy and can survive and remain infective for years," and common disinfectants do not kill them. That is why contaminated insulation is removed rather than sprayed.

Methodology and sources

What this page is, and what it deliberately is not. The regulatory content is quoted from primary sources and is exact: the maternity season dates, the four-night and 50°F exclusion conditions, the disposition rules and the armadillo classification all come from the Florida Fish and Wildlife Conservation Commission and Florida Administrative Code 68A-9.010. The reproductive figures come from University of Florida IFAS Extension, and the parasite persistence figures from the Companion Animal Parasite Council. Each is linked at the point it is used.

The seasonal pattern is different in kind. It reflects the field experience of Dr. Critter's technicians across Central Florida since 1996, and it is stated in qualitative terms, busy or quiet, on purpose. We have not published month-by-month call counts by species or county, because we are not willing to put a number in print that we cannot show the working for. If that changes, this page will carry the sample size and the collection window alongside the figures, and this note will say so. Last reviewed August 2026.
