Roaches are one of the most common pests that homeowners deal with in South Louisiana. But not all roaches are created equal—some are more likely to invade your pantry, while others prefer hanging out in your attic or crawl spaces.
Two cockroach species that often get confused are the American cockroach (a.k.a. palmetto bug) and the Smokybrown cockroach.
Knowing which one you’re dealing with can make a big difference when it comes to getting rid of them effectively.
Key Takeaways
• American and Smokybrown cockroaches may look alike, but they live in different places and have different colors.
• Smoky browns like attics and gutters, while American roaches hang around sewers, basements, and crawl spaces.
• Moisture, food, and small openings around the home can all lead to a cockroach infestation if ignored.
• Professional pest control helps by using the right bait and treatment for the exact roach species inside.
American vs. Smoky Brown Cockroaches: Key Differences
American and Smoky brown cockroaches might seem similar at first, but there are some clear differences between them. Take a look at this side-by-side comparison to see how they stack up.
| Features | American Cockroach | Smokybrown Cockroach |

| Wings | Yes, strong fliers | Yes, strong fliers |
| Preferred Habitat | Sewers, basements, crawl spaces, pantries | Attics, gutters, mulch, woodpiles |
| Common Entry Points | Drains, crevices, and utility openings | Rooflines, attic vents, and tree branches |
| Life Span | Up to 1 year | Around 1 year |
How to Get Rid of American and Smokybrown Roaches
Both types of cockroaches are resilient and fast-breeding, which is why quick action is key. Here’s how we recommend handling an infestation the smart way.
1. Figure Out What Type of Roach You’re Dealing With
Like the Oriental cockroaches, American roaches are sometimes called water bugs. They are reddish-brown with long antennae and are usually found in basements, sewers, or near water sources.
The Smokybrown cockroach is a darker, almost mahogany or dark brown color. They’re known for nesting in attics, gutters, and even under mulch or leaf litter.
You may also spot their oothecae (egg cases) or nymphs, which are smaller versions that haven’t reached maturity yet. Each species has a different life cycle, and understanding that helps with treatment planning.
2. Address Moisture and Entry Points
Roaches love climates with high humidity, and in South Louisiana, they’ve got plenty of it. But there are still ways to make your home less inviting.
Fix any plumbing leaks, and make sure crawl spaces and attics are well-ventilated. Clean out clogged gutters and remove debris like woodpiles that can trap moisture. Inspect your home for crevices, cracked seals, and gaps around vents or doors.
3. Eliminate Their Food Sources
Cockroaches don’t need much to survive. Even a few crumbs or leftover pet food can attract them. Clean up food spills right away, seal dry goods tightly in pantries, and don’t leave dirty dishes overnight.
Remember, they’re constantly in search of food sources, so the less available, the better.
Also, don’t forget to remove pet food bowls overnight and clean up grease buildup behind stoves. Even small amounts of residue can support a cockroach infestation.
4. Use the Right Baits—Not Just Sprays
You might be tempted to grab store-bought sprays, but overuse of these can actually push roaches deeper into hiding or make them avoid professionally applied baits. Plus, sprays often don’t reach where they hide—like inside walls, behind appliances, or in cluttered garages.
At LaJaunie’s Pest Control, we use targeted bait systems and cockroach control methods that are tailored to the specific types of cockroaches found in your home.
While American roaches respond well to granular baits, other species like the German cockroach or brown-banded cockroach require a different approach.
5. Work With a Pest Control Pro
Roaches are hardy pests that can carry pathogens and allergens from unpleasant feces or droppings. And if you’re seeing more than one, you’re likely dealing with a bigger problem than you realize.
