Roof Rat Removal in Fort Lauderdale, FL

On a Fort Lauderdale canal lot the roof rat usually comes from the rear, along the sea wall cap and the dock line, then up a piling, a boat lift cable or a hedge into the palms and onto the roof. The city counts roughly 165 miles of navigable waterway, and every canal-front property has a back edge the owner rarely looks at from the outside.

The water side of the lot carries everything the animal wants. The sea wall cap is a dry, level runway. Dock lines and lift cables are bridges from a neighbor's property. Mangrove and sea grape hedges along the wall give cover, and a boat on a lift or under a canopy stores rope, fenders and food wrappers. From there, a coconut or royal palm with fronds near the eave finishes the trip.

UF/IFAS describes the roof rat as arboreal, moving along branches, wires and palm trunks, and gives its range as about 150 yards from the den. On a finger island that radius covers a dozen houses on both sides of the canal, which is why one sealed roofline holds while an unsealed one refills. Norway rats show up at this same rear edge, burrowing behind the sea wall and under the dock apron, and they stay at ground level. The neighborhood pages for Las Olas Isles and Lauderdale Isles go further into canal-front layouts.

The roof rat is behind nearly every attic call in Fort Lauderdale, and UF/IFAS calls it the worst and most abundant rodent pest in Florida. An adult measures 12 to 14 inches from nose to tail tip, with the tail longer than the head and body combined, which is the quickest field mark against the heavier Norway rat.

Droppings decide most disputes. The roof rat leaves a dropping a quarter to a half inch long, banana shaped and pointed at both ends, which is the one dropping measurement in this trade with a university source behind it. Where two people disagree over a young roof rat and a mouse, the tail proportion and the dropping shape settle it during the inspection.

A scamper across the ceiling once the house goes quiet, droppings on top of the attic insulation, and mangoes or avocados on the lawn with a hole chewed in one side are the three signs that put Fort Lauderdale homeowners on the phone. Any one of them justifies the free inspection.

• Scratching, running or a rolling sound overhead between dusk and dawn, loudest during the November to February cool snaps
• Droppings along the top plate, on the insulation, or on the garage floor under the attic access
• Gnaw marks on soffit edges, vent screens, the foam on the AC line set, or wiring
• Greasy rub marks on a rafter or around the edge of an opening, left by a coat on a repeated route
• Insulation tunneled into runs or pulled into a mound near the air handler
• A musky odor at the attic hatch or in a closet below the attic
• Fruit on the ground with a clean hole and the flesh gone, or citrus peeled from the inside
• Droppings or chewed rope along the dock, on the boat lift beams or on top of the sea wall

Fruit season stretches most of the year in Broward yards. Mango and avocado drop through summer, guava and starfruit through fall, citrus through winter, so there is no month when the food supply shuts off. That is one reason a roof rat population found in January has usually been in the attic since the summer rains.

Most roof rats enter a Fort Lauderdale attic through the open course under the first row of barrel tile, and the component meant to close that course is called a bird stop or eave closure. It is a code-approved metal strip, typically 26 gauge galvanized steel or aluminum, sometimes ventilated with weep holes, and the Department of Energy lists installing bird stopping among its recommended measures for tile roofs. When it is missing, corroded or displaced, the eave becomes a rat-sized slot running the full length of the house.

The palms and fruit trees supply the ladder. Royal, queen, sabal, Washington, date and coconut palms are all common on Broward lots, and a frond or limb within about six feet of the roofline is the route onto the tile. Mango, avocado, citrus, guava, sapodilla and starfruit put the food within the same six feet. Once the animal is on the roof, the same weak points get tested on almost every house in the city.

• The open eave course under the first tile row where the bird stop is missing or has rusted through
• Soffit returns and original soffit screens that have torn or been pushed up
• Gable vents and off-ridge vents with plastic or light wire mesh
• Ridge caps with no screening under them
• Fascia boards that have pulled away from the roof deck with age and sun
• The AC line-set penetration, cracked plumbing vent boots, cable and electrical mast entries

The sealing standard is a quarter inch. UF/IFAS gives that as the rat-proofing figure because a mouse passes a quarter-inch gap and a rat a half-inch one, so the smaller number governs. In Victoria Park, Rio Vista and Poinsettia Heights the fascia, soffit screens and tile are often original to houses from the 1920s through the 1960s, and the gaps are wider for it. The exclusion page covers each closure and the materials that hold.

Sealing first is safe and it is the professional sequence, provided the animals already inside are trapped in the same program and the last opening is closed with a one-way door or a trap on the run. What goes wrong is sealing with nothing set inside, which locks the rats in and sends them chewing into the living space.

The poison question comes up on nearly every call because bait-only plans are the cheapest first quote. The EPA notes that most rodenticides are anticoagulants and that death typically follows four days to two weeks after the animal begins feeding. A rat that feeds in an attic and nests in an attic dies in that attic or a wall void, and the claim that poison makes rats thirsty so they leave to die outdoors is folklore. UF/IFAS adds that trapping reduces the risk of a poisoned rat dying inside a building. The EPA has also pulled second-generation anticoagulants from consumer shelves and restricted them to tamper-resistant stations in residential settings, so any bait beyond the hardware-store tier is a licensed-operator product placed under label rules.

Foam is the other shortcut to avoid. A blob of expanding foam in an open eave course is chewed through in a night, while a fitted metal bird stop, quarter-inch galvanized hardware cloth and sheet metal stay in place through storm season.

A small population with the roofline closed is typically finished within days, and a heavy, long-established one takes one to two months. HomeGuide puts trapping a few animals at two to three days and a severe infestation at one to two months, and the Broward jobs that overrun those figures are nearly always the ones where nothing was sealed.

Roof rat biology sets the pace. UF/IFAS reports that in Florida the species breeds year-round, reaches sexual maturity at three to four months, carries for 21 to 23 days and produces litters of five to eight, four or five times a year. Fort Lauderdale winters are warm enough that the cycle never pauses, so a pair that arrived with the June rains is a colony by the time the cool snaps make them audible. UF/IFAS also notes that roof rats are wary of new objects, which is why traps stay in place for at least a week before anyone moves them.

The multi-month stories in homeowner threads share one detail: a company returning to refill bait with no sealing on the invoice. Ask on the first visit what has been closed and with what, and see the about page for what the routed contractors put in writing.

Trapping and removal runs $250 to $1,200 nationally in HomeGuide's 2026 data, with full-home exclusion at $500 to $2,500 on top, and a Fort Lauderdale quote usually lands inside those bands with the tile eave pushing exclusion toward the upper end. These are national typical-job bands; the free inspection produces the itemized local figure.

Four things move a Broward roof rat quote inside those bands. The length of eave that needs a bird stop, since a tile roof has to be closed end to end. The number of vents, soffit returns and penetrations found open. How long the animals have been in the attic, which sets the trapping schedule. And whether the insulation has to come out. The national guides also price crawl-space and basement work that a slab-on-grade Fort Lauderdale house does not have, so a local quote for the same scope can come in under the national spread. Ask separately whether a monthly monitoring contract is folded into the number.

Fort Lauderdale has no rodent off-season, because the winters never get cold enough to stop roof rats breeding and the yards never stop producing fruit. Demand moves with the weather instead: heavy summer and hurricane-season rain from June through November pushes animals indoors, and the cool snaps from November to February make attic activity loud enough to notice, which is when calls peak.

After a storm

Broward took Wilma in 2005 and Irma in 2017, and Fort Lauderdale saw a record rainfall flood in April 2023. Storms open houses to rodents through mechanisms: wind lifts tiles and tears soffits, the Department of Energy documents one broken tile cascading into others, debris piles become harborage, and flooding drives rats to high ground and attics. The CDC links rises in leptospirosis cases to hurricanes and floods, lists rodents among the reservoirs, and recommends rodent control as post-flood prevention. A post-storm rodent inspection covers that window.

The FDACS credential

Trapping rats or mice in, on or under a structure for hire in Florida requires at minimum an FDACS Limited Commercial Wildlife Management certificate, and applying rodenticide or running a general pest business requires an FDACS pest control business license with a certified operator in General Household Pest and Rodent Control. FWC does not license rat and mouse trappers. Every contractor we route holds the FDACS credential the job needs, and you can look the license number up with FDACS before work starts.

Five checks before the ladder goes up

Five questions separate a job that ends from one that drags on, and whoever attends should answer all of them on the first visit.

1. Ask for the FDACS license number and check it in the state lookup.
2. Have the quote broken out line by line: inspection, sealing, trapping, cleanup, and any ongoing service.
3. Ask what will be closed, with what material, and whether the eave gets a fitted bird stop or foam.
4. Ask what warranty terms apply to the sealing, whether the term renews, and what happens if activity returns.
5. Ask how many follow-up visits are included and who removes the trapped animals.

The contact page is the place to put those questions before anyone comes out.

A Broward rodent job is a sequence of separate lines, and these are the pages that cover the steps on either side of this one.

• Rodent Exclusion: Closing the tile eave with a bird stop, then the soffits, vents and penetrations, to the quarter-inch standard.
• Rodent Inspection: A free walk of the roofline, attic, exterior and dock line that sets the order of the job.
• Attic Cleanup: Removing droppings and soaked insulation from a hot vented attic, then sanitizing it.

How the pieces fit together, and which license to look up, is covered on the about page. The contact page has the hours and the office address.
