Central Florida’s warm, humid subtropical climate provides prime habitat for brown rats year-round. Average temperatures range from the low 70sF (22C) in the north to upper 70sF (25C) in the south, with summer highs in the 90sF (30sC). Annual rainfall exceeds 50 inches (1270 mm) especially during the summer rainy season.
The combination of warmth and moisture allows dense vegetation, crops, and refuse to accumulate. Rural wetlands, forests, farms, landfills, and sewers surround urban centers, harboring large brown rat populations. Developed areas offer garbage and food waste. Brown rats inhabit burrows, sewers, basements, and ground floors. Older buildings provide entry through cracks and faulty plumbing.
As prolific breeders, brown rat numbers multiply rapidly given central Florida’s ideal climate, shelter, and food availability. Diligent exclusion, sanitation, and population control is required to prevent destructive infestations due to the region’s prime conditions.
