Winter in New Orleans doesn’t bring snow, but it does bring a shift in the local wildlife. As temperatures drop, many pests that were thriving outdoors start looking for a warmer place to stay. Unfortunately, that often means your home. Knowing which critters are likely to show up can help you protect your space.
This guide will walk you through the most common winter pests in New Orleans, explaining why they’re a problem and what you can do about them. Read on to learn how to keep your home pest-free this winter.
Common Winter Pests in New Orleans
While summer might be peak pest season, winter brings its own unique set of unwelcome guests. Mild Louisiana winters mean that many pests remain active, seeking shelter, food, and warmth inside homes and businesses. Here are the main culprits to watch for.
Rodents (Rats and Mice)
Rodents are perhaps the most common winter intruders in New Orleans. As their outdoor food sources become scarce and the weather cools, mice and rats are drawn to the warmth and reliable food supply inside our homes.
- Signs of Infestation: Look for droppings in pantries, drawers, or under sinks. You might also find gnaw marks on food packaging, furniture, or wires. Scratching and scurrying sounds in walls or ceilings, especially at night, are another clear indicator.
- Risks: Rodents aren’t just a nuisance; they pose significant health risks. They can contaminate food and surfaces, spreading diseases like salmonellosis and hantavirus. Their constant gnawing can also damage electrical wiring, creating a serious fire hazard.
Cockroaches
New Orleans is no stranger to cockroaches, and winter doesn’t offer much of a break. Species like the American cockroach and the German cockroach will readily move indoors to escape the cold. They are incredibly resilient and can find everything they need to survive and multiply within your walls.
- Signs of Infestation: Spotting a live cockroach, especially during the day, often points to a larger infestation. Other signs include small, dark droppings that resemble coffee grounds, oval-shaped egg casings (oothecae) in hidden spots, and a musty, unpleasant odor.
- Risks: Cockroaches are known carriers of bacteria, including E. coli and Salmonella. They can trigger allergies and asthma attacks, particularly in children.
Spiders
While spiders are present year-round, you might notice more of them inside during the winter. They follow their food source, so if other insects like flies and roaches have moved into your home, spiders won’t be far behind.
- Signs of Infestation: The most obvious sign is an increase in spider webs, particularly in corners, basements, and attics. While most house spiders are harmless, New Orleans is home to the venomous black widow and brown recluse, which prefer dark, undisturbed areas.
- Risks: A bite from a black widow or brown recluse spider requires immediate medical attention. Even non-venomous spiders can be a nuisance and indicate a larger pest problem.
Termites
In Louisiana’s climate, termites—especially the destructive Formosan “super-termite”—can remain active throughout the winter. While swarming season is typically in the spring, a warm winter day can still trigger activity. An indoor colony will continue to eat away at your home’s structure 24/7, regardless of the season.
- Signs of Infestation: Keep an eye out for mud tubes on foundation walls, discarded wings near windowsills, or wood that sounds hollow when tapped. Sagging floors, peeling paint, or tiny holes in drywall are also red flags.
- Risks: Termites cause billions of dollars in structural damage to U.S. properties each year. An untreated infestation can compromise the safety and integrity of your home.
