Identifying Norway Rats In Florida 

Norway rats are sturdy and hefty rodents that are larger and often more aggressive than other rat species found in Florida. These particular rodents are found all over the United States – and are especially abundant in coastal areas where they can swim and – in some cases – even catch fish with their paws (which is why they’re referred to as ‘wharf rats’). Then typically tend to thrive in environments close to humans, relying on our habitats for food and shelter.

Here are some ways to identify Norway rats from their rodent counterparts:

Physical Appearance: Norway rats are stocky and larger than other rodents, typically measuring around 16 inches long, including a shorter tail. They have coarse fur that is usually brown or gray with lighter underbellies. In comparison, roof rats are smaller and have longer tails, as well as more pronounced features like pointed noses and larger ears.

Nose and Ear Shape: Norway rats have a blunt snout and small ears relative to their body size. In contrast, roof rats have elongated, pointed snouts and significantly larger ears.

Behavioral Traits: Norway rats are primarily ground dwellers, often nesting in lower areas such as basements or gardens. They are nocturnal foragers, most active during dusk and dawn, but may scavenge at any time of day. The gnawing activity of Norway rats can cause considerable damage to homes, gardens, and structures.

Feeding Preferences: Norway rats will eat almost anything but prefer cereal grains, meats, fish, nuts, and some fruits. This contrasts with roof rats, who tend to lean more toward fruits and vegetables. Observing the types of food and waste can help in identifying their presence. 

Where In Florida Do Norway Rats Live?

Norway rats are commonly found throughout Florida, particularly in coastal, urban, and suburban areas where they can burrow, easily find discarded garbage, and quickly access food and shelter. Their adaptability to human environments makes cities like Jacksonville and Northeast Florida hotspots for their activity. 

In general, Norway rats are ground burrowing animals and construct burrows that are 2 to 3 inches in diameter and up to 6.5 feet in length. Burrows are constructed outdoors beside foundations and gardens. 

Norway rats are nocturnal and will enter homes at night in search of food, returning back to their burrow. If nests are found inside homes, they are typically in basements and crawl spaces. If a population is large, Norway rats will nest in the upper areas of a home or structure.

In residential properties, Norway rats typically burrow under foundations, in woodpiles, and in gardens, especially where food sources are abundant. They are opportunistic feeders and will seek out environments that provide easy access to nourishment, making homes and yards attractive habitats for them.

Additionally, while they are primarily associated with urban settings, Norway rats can also be found in rural areas, particularly near agricultural sites. Here, they can access crops and grain storage facilities, further expanding their range. 

Their ability to thrive in various environments highlights the need for effective pest control measures, especially in areas where they can become a nuisance or pose health risks.

How Common Are Norway Rats In Florida?

Norway rats are quite common in Florida – and due to its coastal setting, you might find a higher population of these rodents by the sea

Norway rats’ adaptability and reliance on human habitats contribute to their prevalence across the state.

Are Norway Rats Dangerous?

If left untreated, Norway rats can certainly be dangerous. 

Norway rats can damage foundations, slabs, garden crops, and plants as they burrow and gnaw to find food and shelter. Inside homes these pests may cause extensive damage when nesting in walls and attics. Accounts of rodents starting fires through the gnawing of electrical wires have been widely reported. Chewed, exposed wires inside walls can spark, causing interior walls to catch fire.

When foraging for food, these rats consume and contaminate food meant for humans, pets, and livestock. Salmonella, leptospirosis, and rat-bite fever are among the dozens of diseases spread by Norway rats.
