Not much. Gainesville averages only about 15 freezing nights a year, and UF/IFAS says roof rats breed all year in Florida, with peaks in spring and fall. A few rats in an attic can keep growing right through the winter.
From a Victorian porch house in the Duckpond to a student rental off University Avenue to a newer home out by Haile Plantation, rats in Gainesville usually come down from the trees and in through the roofline. We find each opening, close it with metal, trap the rodents already inside and come back to confirm the house is quiet.
Gainesville has been named a Tree City USA every year since 1982, and a 2016 study put the city’s tree canopy at about 47% of its land. On the south edge sits Paynes Prairie Preserve State Park, more than 21,000 acres of marsh, live oak hammock and pine sandhill. Few Florida cities have this much green so close to so many roofs.
That is good news for shade and bad news for attics. The roof rat (Rattus rattus) is a climber. It uses oak limbs, power lines and fences to reach the roof, then slips in at a soffit gap, an open gable vent or the seam where a porch roof meets the wall. UF/IFAS says roof rats will travel about 150 yards from the nest for food or water, so the rat in your attic may live in a tree 2 lots away.
Winters here are mild for North Florida. Gainesville averages only about 15 nights at or below freezing, mostly between early December and late February. Roof rats breed all year in Florida, with peaks in spring and fall, so there is no long cold break that slows them down.
Trimming limbs back from the roof helps, but in a city this green it is never enough on its own. Sealing the house is what keeps rats out.

The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is based in Gainesville, and its Extension service publishes the guides most Florida pest pros work from. Here is what its roof rat guide says, and what it means for a Gainesville home.
UF/IFAS calls the roof rat the worst rodent pest in Florida and the most abundant. Adults are 12 to 14 inches long, nose to tail, and weigh 5 to 10 ounces. Their droppings are black, banana shaped and about 1/4 to 1/2 inch long. Noise in the attic at night is the classic sign.
The same guide says the Norway rat is rare in Florida. When we do find a burrowing rat, it is usually under a slab, a shed or a pile of stored material at ground level, not in the attic.
UF/IFAS names the native cotton rat, together with the roof rat, as a crop pest in Florida fields. A rat in your attic or running a fence line is almost always a roof rat. A rodent seen only out in a field or pasture edge may be the native one.
After a pregnancy of about 21 to 23 days.
For each female roof rat.
So young rats start new colonies fast.
None are registered for roof rats, and UF/IFAS finds no evidence ultrasonic devices work.

The Northeast Gainesville Residential District, known locally as the Duckpond, has 229 historic buildings and was added to the National Register of Historic Places in 1980. Those homes fail in very different places than a new build on the west side. This is where we look first.
| Part of Gainesville | What the homes are like | First places we check |
|---|---|---|
| The Duckpond (Northeast Gainesville Residential District) | Late 1800s and early 1900s homes in Victorian, Mediterranean and Colonial styles, under big shade trees | Roofline and attic. Old gable and soffit vents, porch roof seams, gaps where later additions meet the original house, utility lines through old walls |
| Pleasant Street and the Southeast Gainesville Residential District | Older historic neighborhoods near downtown | Foundation vents and floor openings, gaps around plumbing, eaves and fascia boards with age or storm damage |
| Near campus, around University Avenue and the UF area | Student apartments, rental houses, duplexes and fraternity and sorority houses | Shared walls. Pipe chases under sinks, gaps behind appliances, back doors, dumpster pads and trash areas |
| Downtown, Depot Park and Innovation Square | Restaurants, offices and new infill apartments | Loading and back doors, grease and dumpster areas, ceiling spaces and utility runs between units |
| South side near Paynes Prairie, Bivens Arm and Sweetwater Wetlands Park | Homes close to big natural areas and tree lines | Limbs and vines touching the roof, garage door corners, sheds and woodpiles near the house |
| Haile Plantation and the west side | Planned communities and newer subdivisions | Small gaps. Garage door seals, AC line and cable holes, dryer vents, roof edges near tall trees |

Rats come for food and cover. The City of Gainesville’s curbside and code rules already cut off a lot of both, if you follow them. These are the ones that matter most for rodents.
Set the garbage cart at the curb by 7 AM on collection day, not the night before, and bring it back by 9 PM. Keep the lid fully closed.
The city says not to pile garbage bags on or around the cart. Extra trash goes in Official Yellow Bags, 4 feet from the cart.
Yard waste is picked up weekly. Branches up to 5 feet long and 8 inches thick. Leaves go in paper bags, never plastic, so piles do not sit for weeks.
City code says to keep grass 12 inches or less, and junk, trash and debris cannot be left in the yard.
Gainesville Code Enforcement tells owners to maintain a pest control program to get rid of harmful insects and rodents. Rental units also fall under the city’s Residential Rental Unit Ordinance, Chapter 14.5. Questions about rentals go to the Rental Housing line at 352-334-5035.
Overgrowth, junk piles or loose trash next door can keep a rat problem going. Call Code Enforcement at 352-334-5030 or file online through the city. Gainesville does not accept anonymous complaints, so you will need to give your name and address.

Most Gainesville jobs combine a few of these: an inspection, sealing, trapping and cleanup. Pick a service to learn more, or call and we will tell you what your property needs.
A tight newer home may need only a few gaps closed. A 100 year old house in the Duckpond can have openings along the whole roofline. Either way the work runs in this order, and you approve the plan and price before anything starts.
Roof, attic, eaves, foundation, garage and yard, including limbs over the roof. You get photos of every entry point and a written plan.
Gaps sealed with sheet metal, 1/4 inch hardware cloth, mesh and cement. Spray foam alone is not used, because rats chew through it.
Snap traps placed on the runways rats use, marked by droppings and greasy rub marks, then checked and moved on return visits.
Droppings, nests and soiled insulation removed wet with disinfectant, never swept or vacuumed dry.
We look for fresh droppings, new chew marks or moved bait before we close the job.
The University of Florida had 54,814 students in fall 2023, and only about 9,200 of them live in campus residence halls. Most of the rest rent in Gainesville, which is a big reason only 37.7% of homes in the city are lived in by their owners. Rodent calls from apartments, duplexes and shared houses are a normal part of the year here.
Section 83.51, Florida Statutes, says the landlord of a dwelling unit other than a single family home or duplex must provide for the extermination of rats, mice, roaches, ants, wood destroying organisms and bedbugs, unless the lease or the law says otherwise. For single family homes and duplexes, that duty can be changed in writing, so check your lease.
The same section covers what happens if you have to leave during a treatment. The tenant may be asked to move out for up to 4 days, with 7 days’ written notice. The landlord is not liable for damages in that case but must reduce the rent for that time.

Gainesville attics also get squirrels, bats, raccoons and opossums. Rodents leave their own set of clues. Two or more of these is a good reason to call.
Rats are busiest at night. Steady daytime noise points more to squirrels.
Black, 1/4 to 1/2 inch, along walls and on insulation. Mouse droppings are much smaller, like rice.
Citrus with a hole about the size of a quarter and the inside eaten is a roof rat sign, per UF/IFAS.
Greasy rub marks on beams, pipes and the top of walls where rats run the same path every night.

The CDC warns that sweeping or vacuuming rodent droppings can put germs into the air. Air the space out for 30 minutes, wear rubber or plastic gloves, soak droppings and nests with disinfectant or 1 part bleach to 9 parts water for 5 minutes, then wipe them up with paper towels.
In Florida, pest control companies are licensed by the Florida Department of Agriculture and Consumer Services (FDACS) under Chapter 482, Florida Statutes. Ask for the license number before work starts. Our team is EPA and FDACS certified.

Older homes in the Northeast Gainesville historic district often have many small openings: old vents, porch roof seams, gaps where additions meet the original walls and utility lines through old siding. Big shade trees give rats a path to all of them. Sealing the whole roofline, not just one hole, is what makes it stop.
In most apartments, the landlord. Section 83.51, Florida Statutes, says landlords of units other than single family homes and duplexes must provide for extermination of rats and mice. Houses and duplexes can be different if the lease says so in writing. This is general information, not legal advice.
Yes. You will likely always have some rodents outside, since roof rats can travel about 150 yards for food. The goal is to keep them out of the house. Once every gap at the roof, walls and foundation is closed with metal or hardware cloth, they have no way in.
UF/IFAS lists the native cotton rat as a pest in Florida fields and crops. A rat living in your attic, walls or trees and running along fences is almost always a roof rat, which UF/IFAS calls the most abundant rodent pest in the state. We identify the species at the inspection.
It depends on how many entry points need sealing, the size of the attic and how many rodents are inside. We do not guess over the phone. After the inspection you get a written plan and price, and nothing starts until you approve it.
The City of Gainesville lists dead animals among items that should not go in the garbage cart. Call the Solid Waste Division at 352-334-2330 for options, or have us remove it. If you smell one inside a wall, we can find it, remove it and clean the area.
