The roof rat (Rattus rattus) is the most common rodent in Polk County, particularly in homes with tile roofs, mature oak canopy, citrus trees, or palm trees adjacent to the structure. Norway rats (Rattus norvegicus) and house mice (Mus musculus) are also present. Call the number below to be connected with an FDACS-licensed rodent control operator for inspection, trapping, exclusion, and ongoing monitoring.
The dispatched operator performs a structural inspection to identify entry points, sets traps in identified rodent runways, deploys exclusion materials (hardware cloth, steel wool, expanding foam) at entry points, and typically returns at 7–14 day intervals until activity ceases.
Why Polk County Has Heavy Roof Rat Pressure
Roof rats are particularly prevalent in Polk County because:
Tile roofs. Polk County’s Spanish/Mediterranean architectural heritage includes a high concentration of barrel tile and S-tile roofs — particularly in the historic neighborhoods of Lakeland (Cleveland Heights, Lake Hollingsworth), Lake Wales (Bok Tower historic district), and Winter Haven. Tile roof valleys, ridge gaps, and tile-to-wall transitions provide ideal roof rat entry and harborage points.
Mature oak canopy. Lakeland’s Lake Hollingsworth, Lake Morton, Cleveland Heights, and Lakeland Highlands neighborhoods feature extensive live oak (Quercus virginiana) and laurel oak canopy that overhangs roof lines, creating tree-to-roof bridges that roof rats exploit.
Palm trees and citrus. Palm fronds and citrus tree branches provide additional roof access. Polk County’s citrus heritage has left thousands of mature citrus trees in residential yards. Roof rats nest in palm fronds and citrus tree crowns.
Attics and vents. Older Polk County housing stock features attic vents, soffit vents, gable vents, and ridge vents that have deteriorated screening. Roof rats enter through gaps as small as 1/2 inch.
The result is that any Polk County home with tile roof + mature canopy + adjacent fruit trees has elevated roof rat probability — and the dispatched operator will typically find evidence of activity even when homeowners haven’t yet seen droppings or heard scratching.
Identifying Rodent Activity
Droppings. Roof rat droppings are ~1/2 inch, sausage-shaped, pointed at one end. Norway rat droppings are larger (~3/4 inch), blunter ends. Mouse droppings are smaller (~1/8 inch), rice-grain shaped. Common locations: attic insulation, kitchen pantries, garages, under sinks, near food storage.
Scratching sounds. Roof rats typically active at night. Attic scratching, ceiling activity, and wall-void movement are common. Heavier thumping suggests Norway rats.
Gnaw marks. Rodents must continuously gnaw to wear down growing incisors. Look for gnaw marks on wood structural members, electrical wires (a fire hazard), plastic pipes, and food storage containers.
Runways. Rodents follow consistent paths along walls, baseboards, and pipes. Look for grease marks on walls, well-worn paths through insulation, and pellet accumulations along base of walls.
Nest material. Shredded paper, fabric, insulation, and palm frond debris compiled in protected areas.
Visual sighting. A rat sighted during daylight typically indicates established population (rodents are normally nocturnal — daytime sighting means the colony is large enough to push some members out).
Treatment Approach
Inspection
The dispatched operator performs systematic structural inspection — roof line, soffit, fascia, eaves, attic, crawl space (if accessible), garage, kitchen, plumbing chases, electrical penetrations. Goal: identify all current entry points and active runways.
Trapping
Snap traps and electronic kill traps placed along identified runways and at suspected harborage points. Bait-based trapping (rodenticide bait stations) is used in select situations but is generally not the primary approach due to risk of poisoned-rodent-death-in-wall situations.
Exclusion
The critical step. Without exclusion, trapping is just population control — new rodents will enter and re-populate. The operator seals all identified entry points:
- Hardware cloth (1/4 inch mesh) over vents and openings
- Steel wool with caulk at small gaps
- Expanding foam at larger gaps (combined with steel wool — rodents chew through foam alone)
- Sheet metal collars around pipes and conduit
- Door sweeps on garage and exterior doors
- Roof line repairs — tile gap sealing, ridge vent re-screening, soffit vent re-screening
Trim back tree branches and palm fronds that bridge to the roof line.
Follow-Up Monitoring
Return visits at 7–14 day intervals until activity ceases. Typically 2–4 visits for a moderate infestation, 5+ visits for severe.
Ongoing Service
After initial elimination, many Polk County homeowners contract for quarterly or annual exterior bait station monitoring as a preventive measure.
When To Call
- Scratching sounds in attic, especially at night
- Droppings discovered in attic, garage, or kitchen areas

- Citrus tree or palm tree directly adjacent to roof line (preventive)
- New homeowner moving into Polk County tile-roof home (preventive)
- Restaurant or food service property with health inspection requirements
- Rodent damage triggering insurance claim
