Rats, Squirrels, and Raccoons in Florida Homes: Rules and Fixes

Keeping Them Out and the Rules for Removing Them

Scratching in the attic at night, chewed wires, a raided trash can: most Central Florida homeowners deal with unwanted animals sooner or later. Rats, squirrels, and raccoons all want the same thing, a dry, protected spot near food, and they all get in the same way, through gaps in the roofline, soffits, vents, and foundation. Florida also has specific rules on trapping, relocating, and feeding wildlife that many homeowners don’t know about.

Short version: Sealing entry points is the long-term fix for all three. Rats can squeeze through gaps about 1/2 inch wide and mice about 1/4 inch, so close gaps with hardware cloth, sheet metal, or concrete, not foam. In Florida, property owners may remove nuisance wildlife causing damage, but traps must be checked at least every 24 hours, and a captured animal must be released or humanely euthanized within 24 hours. It can be released on the same property, or moved only within the same county to at least 40 contiguous acres with the landowner’s written permission. Placing food in a way that attracts raccoons is illegal. Bats can’t be excluded from a building during maternity season, roughly mid-April to mid-August. Raccoons and bats are Florida’s main rabies carriers, so any bite or scratch needs prompt medical attention. FWC trapping rules are changing on December 31, 2026, so check them before setting a trap.

Who’s in the attic? Common signs

Animal	When you hear it	Other signs	Typical way in
Roof rats and mice	Night: light scurrying and scratching	Droppings (fresh ones black and shiny), gnaw marks, greasy rub marks along runways	Gaps of 1/2 inch (rats) or 1/4 inch (mice) at rooflines, vents, pipes, and wires; palm trees and vines touching the roof
Gray squirrels	Daytime, especially early morning and late afternoon	Chewed soffits, fascia, and vent screens; nesting material	Gaps at soffits, roof returns, and gable vents, often reached from overhanging branches
Raccoons	Night: heavy thumping and walking	Torn soffits or screens, tipped trash, droppings on roofs, docks, or pool steps	Torn screens, damaged soffits, open chimneys, under decks and mobile homes
Bats	Dusk, when they leave to feed	Droppings below an entry point, stains around gaps	Gaps larger than about 1/2 inch at roof edges, tile roofs, and behind shutters

Sealing the house: the fix that lasts

Traps and poison handle the animals already inside, but more will follow if the openings stay. UF/IFAS recommends rodent-resistant materials:

Hardware cloth with openings of 1/4 inch or smaller.
26-gauge or heavier sheet metal.
Mortar or concrete.

Foam and plastic get chewed through. Places to check and seal:

Gaps where the soffit meets the roof or wall, and loose or damaged soffit panels.
Gable, ridge, and roof vents, and dryer and bath exhaust vents.
Openings around pipes, AC lines, and cables entering the house.
Chimneys, which need a metal cap with screening.
Garage door seals and gaps under doors.

Trim tree branches and palm fronds back from the roof, and keep vines off the walls, since roof rats and squirrels use them as highways.

Make sure animals are out before sealing. Sealing animals in leads to frantic chewing, damage, dead animals, and odor. One-way exclusion doors let animals leave but not return. Dusting flour at an entry and checking for tracks after dark can confirm whether the opening is still in use. Be especially careful in spring, when squirrels and raccoons may have young inside. UF/IFAS warns that chasing out a mother raccoon and sealing the hole often backfires, because she’ll force her way back to her young.

Roof work, soffit repair, and vent screening tie into the roof’s overall condition. See Florida roof lifespan and replacement.

Rats and mice

Florida homes deal with three main rodents:

Roof rat: A slim climber with a tail longer than its body. It nests in attics, palms, and dense shrubs, and is the one most Central Florida homeowners hear overhead.
Norway rat: Heavier, and burrows under slabs and along canals.
House mouse: Moves into walls and cabinets.

UF/IFAS control recommendations:

Remove food and water: Keep trash in tight-lidded cans, store pet food and birdseed in sealed containers, pick up fallen fruit, and fix leaks. Ongoing sanitation matters more than a once-a-year cleanup.
Trap first for small problems. Set snap traps at right angles to walls and runways. Rats are wary, so leave traps baited but unset for a few days before setting them.
Use poison bait carefully: Rodenticides suit larger infestations, but outdoors they must go in tamper-resistant bait stations a child or dog can’t open. Pets and wildlife can be poisoned by eating poisoned rodents, so pick up carcasses. A rodent that dies in a wall can smell for two to four weeks.
Protect the natural help: Owls, hawks, and nonvenomous rat snakes eat many rodents. Cats and dogs are poor rodent control, and outdoor pet food attracts rats.

Cleaning up droppings: The CDC advises against sweeping or vacuuming droppings, which can put germs in the air. Its steps:

Air the space out for about 30 minutes.
Wear rubber or plastic gloves.
Spray droppings and nests with a disinfectant or a fresh mix of 1 part bleach to 9 parts water, and let it soak 5 minutes.
Wipe up with paper towels, then double-bag and discard everything.

Heavy infestations call for more protection or a professional.

Squirrels

Gray squirrels normally nest in trees but readily move into attics when they find an opening. They can breed up to twice a year, so spring and late summer often bring a nest of young. Once inside, they chew wood, vent screens, and sometimes wiring.

The approach:

Find the entry point, usually at a soffit or roof return.
Make sure no young are inside.
Install a one-way exit, or trap under FWC’s nuisance wildlife rules.
Seal the hole with metal, and trim back the branches that give them roof access.

Florida also has fox squirrels and southern flying squirrels. If it isn’t clearly a gray squirrel, check with an FWC regional office before trapping.

Raccoons

Raccoons get into attics through torn screens, damaged soffits, and open chimneys. They also den under decks and mobile homes, raid garbage, and sometimes use pool steps as a latrine. UF/IFAS and FWC recommend:

Secure trash in sturdy cans with clamped or latched lids, or keep cans in the garage until pickup day. See trash, recycling, and bears in Central Florida.
Feed pets indoors, or pick up outdoor pet food before dusk, and don’t leave birdseed or fallen fruit on the ground.
Don’t feed raccoons. Florida rule 68A-4.001 prohibits placing food in a way that attracts raccoons, foxes, coyotes, or bears. Feeding raises disease risk and makes animals bolder.
Use a one-way door for an attic raccoon without young. UF/IFAS considers live trapping the least desirable option.
Protect gardens with a single electric wire about 6 to 8 inches above the ground. Repellents and scare devices generally don’t work.

A raccoon out during the day isn’t necessarily sick. But never handle one, and keep pets’ rabies vaccinations current.

Florida’s rules on trapping and relocating wildlife

Under FWC’s nuisance wildlife rules, a property owner, or someone the owner authorizes, may take nuisance wildlife that is damaging property, threatening safety, or causing problems in or under a building. Most cases don’t need a permit or notice to FWC. The key rules:

Check traps at least once every 24 hours.
Release or euthanize a live-captured animal within 24 hours. Euthanasia must be humane.
Release locations: Native animals may be released on the same property where they were caught. Moving them elsewhere is allowed only within the same county, onto at least 40 contiguous acres, with the landowner’s written permission, and not against any county rabies quarantine. Parks and other public lands are off-limits without the land manager’s written permission.
Nonnative animals can’t be released anywhere and must be humanely euthanized.
Restricted species: Bats, bears, alligators, deer, bobcats, protected birds, and listed species have their own restrictions or need permits.

FWC discourages relocation. Moved animals often starve, get pushed out by resident wildlife, or spread disease, and another animal usually moves into the empty spot unless the entry is sealed.

Rule changes coming December 31, 2026. FWC’s new trapping rules are scheduled to take effect at the end of 2026. They include:

A free wildlife trapping permit, with required training.
Trap checks within 12 hours instead of 24.
Handling captured nuisance animals within 12 hours of inspection.
New cage-trap door standards.

Check FWC’s trapping rules page before setting a trap after that date.

Hiring help: FWC doesn’t license nuisance wildlife trappers, but keeps a voluntary list of operators. Ask how they’ll confirm no young are left inside, whether they seal entry points and guarantee the work, and what happens to captured animals. Pest control companies licensed for rodents fall under the Florida Department of Agriculture and Consumer Services. See palmetto bugs, roaches, and spiders for how to check a license.

Bats: protected, with a strict calendar

Bats roost in attics, under barrel tiles, and behind shutters, and they eat huge numbers of insects. In Florida they can’t be killed, trapped, or relocated, and poisons and fumigants are illegal. The only legal option is exclusion: one-way exit devices left up at least four nights, followed by permanent sealing. FWC’s rules:

Maternity season: Exclusion is prohibited while flightless young are in the roost, roughly April 15 to August 15.
Temperature: Exclude only when overnight lows are forecast at 50°F or warmer.
Best timing: Fall, after the young can fly.

During maternity season, seal off the living space from the roost and wait. Never handle a bat with bare hands. Bats are a main rabies carrier in Florida, so get medical care right away after any bite or contact.

Rabies and bites

The Florida Department of Health identifies raccoons and bats as the main wildlife sources of rabies in Florida. Foxes, bobcats, otters, and outdoor cats also turn up, and outdoor cats are the domestic animal most often found rabid. Rabies is almost always fatal once symptoms start but preventable with prompt treatment. After any bite or scratch from a wild animal or unknown pet:

Wash the wound thoroughly with soap and water.
Get medical care right away.
Report the bite to the county health department or animal services.
If the animal is dead, don’t handle it or damage its head, which may be needed for testing.

Florida law requires dogs, cats, and ferrets to be vaccinated against rabies.

Buying a home? Look for droppings, chewed soffits, and nesting material in the attic during the inspection. See the home inspection checklist. Attic contamination and roof leaks also feed mold problems; see Florida mold prevention. Yard pests are covered in fire ants and mosquitoes in Central Florida.

Frequently Asked Questions

Yes, if it’s causing damage or problems. Under FWC rules, traps must be checked at least every 24 hours, and the animal must be released or humanely euthanized within 24 hours. New FWC trapping rules take effect December 31, 2026, including a free permit and 12-hour checks, so check FWC’s site first.

Not freely. Native animals can be released on the same property, or moved only within the same county to at least 40 contiguous acres with the landowner’s written permission. Public parks need the land manager’s written permission, and nonnative animals can’t be released at all.

UF/IFAS says rats can squeeze through gaps about 1/2 inch wide and mice about 1/4 inch. Seal gaps with hardware cloth, sheet metal, or concrete, since foam and plastic get chewed through.

Only outside maternity season, roughly mid-August to mid-April, using one-way exclusion devices left up at least four nights when overnight lows are 50°F or warmer. Killing, trapping, or poisoning bats is illegal.

Placing food in a way that attracts raccoons, foxes, coyotes, or bears is prohibited under FWC rule 68A-4.001. Feeding makes animals bolder and raises disease risk, so keep pet food, trash, and birdseed secured.

Wash the wound with soap and water, get medical care right away, and report it to the county health department or animal services. Raccoons and bats are Florida’s main rabies carriers, and treatment works when started promptly.
