This article will introduce you to the top rodent species found in Lake Charles and provide insights into their behaviors, habitats, and risks.

Why Rodents Thrive in Lake Charles

The warm, humid climate and the abundance of water sources like lakes, rivers, and swamps make Lake Charles a perfect environment for rodents. These conditions allow rodents to thrive year-round, and the urban areas provide even more opportunities for them to find food and shelter.

Whether you’re a homeowner or a business owner, you’re likely to encounter some of these critters at some point, so knowing how to spot and manage them is essential.

Appearance: Stocky body, blunt nose, shaggy fur, and a tail that is shorter than the length of their body.
Color: Usually brown or gray.

Habitat and Behavior

Norway rats are known for burrowing and are often found in basements, crawl spaces, and near building foundations. They commonly build nests in burrows outside but will enter buildings if they find access. These rodents are excellent swimmers, which is no surprise given the waterways in and around Lake Charles.

Risks

They can chew through almost anything, including wood and plastic, causing structural damage.
Norway rats are known carriers of diseases like leptospirosis and salmonella.

2. Roof Rats (Rattus rattus)

Habitat and Behavior

True to their name, roof rats are excellent climbers. They prefer elevated areas, such as attics, roofs, and treetops. You might also find them in high shelves or storage areas in your home or business.

Risks

Roof rats are notorious for contaminating food and food preparation areas.
They can damage wiring, which increases the risk of electrical fires.

3. House Mice (Mus musculus)

Description

Habitat and Behavior

House mice are among the most common rodents in urban areas like Lake Charles. They can nest almost anywhere, from wall voids to storage boxes, and they tend to stay close to food sources. These mice are nocturnal and can reproduce rapidly, leading to infestations if not addressed promptly.

Risks

House mice can spread diseases such as hantavirus through their droppings and urine.
They can cause damage by gnawing on wires, furniture, and stored items.

4. Deer Mice (Peromyscus maniculatus)

Risks

Deer mice are primary carriers of hantavirus, which can pose serious health risks.
They may damage household items by gnawing on them.

Protecting Your Home or Business from Rodents

Rodents can cause significant damage and introduce health risks, so prevention is key. Here are some practical steps to keep them at bay:

Seal Entry Points: Use steel wool or caulk to seal gaps and cracks around doors, windows, and foundations.
Declutter and Clean: Clear away piles of debris, long grass, and unused items that may provide hiding spots.
Store Food Securely: Keep food in rodent-proof containers and dispose of waste promptly.
Regular Maintenance: Inspect for signs of rodent activity, such as droppings, gnaw marks, or scratching sounds.

If you suspect an infestation, it’s best to act quickly. Professional pest control services can help identify the source of the problem and provide effective solutions.
