The Florida woods cockroach, often misunderstood and mistaken for more invasive pests, is a unique species native to the southeastern United States. Known for its distinctive appearance and behavior, this roach prefers outdoor habitats but can occasionally wander indoors, causing concern for homeowners.
This guide dives deep into everything you need to know about the Florida woods cockroach, from its biology and habits to effective control methods. Whether you’re dealing with a potential infestation or simply curious about this insect, this article covers facts, identification, behavior, habitat, and more.
What Is a Florida Woods Cockroach?
The Florida woods cockroach, scientifically named Eurycotis floridana, is a large, outdoor-dwelling roach commonly found in warm, humid environments. Often called the “palmetto bug” or “Florida stink roach,” it thrives in natural settings like forests, wooded areas, and palmetto groves. Unlike household pests such as German or American cockroaches, this species prefers to live outside and only enters homes by accident or in search of food and shelter. Its nickname, “stink roach,” comes from its ability to release a foul-smelling chemical as a defense mechanism.
This roach plays a vital role in ecosystems by breaking down decaying plant matter, contributing to nutrient recycling. However, its occasional indoor presence and off-putting odor make it a pest of interest for homeowners in Florida and nearby states. Understanding what is a Florida woods cockroach is the first step to distinguishing it from other roaches and managing its presence effectively.
Florida Woods Cockroach Facts
Here are some key Florida woods cockroach facts to help you understand this insect better:
- Scientific Name: Eurycotis floridana

- Flight: Lacks fully developed wings and cannot fly, unlike some other roach species
These facts highlight the Florida woods cockroach as a unique species with distinct ecological roles and behaviors. Its preference for outdoor environments sets it apart from more troublesome indoor pests.
Florida Woods Cockroach Identification
Accurate Florida woods cockroach identification is crucial for distinguishing it from other roaches and determining the right control measures. Here’s how to identify this species:
- Size: Adults measure 1.2 to 1.6 inches (30–40 mm) in length and about 1 inch (24 mm) in width, making them larger than many common roaches.
- Color: Reddish-brown to nearly black, with a glossy, armored appearance.
- Wings: Lacks fully developed wings, having only short, leathery wing pads (tegmina) that do not cover the abdomen.
- Body Shape: Wide, oval, and robust, resembling a flattened egg.
- Antennae: Long, nearly the length of the body, extending forward rather than curling back.
- Distinctive Features: Nymphs have pale yellow bands on the thorax, while adults may have cerci (protrusions) at the rear. Females have a V-shaped notch in the rectal area, while males have filaments near the cerci.
- Odor: Emits a strong, unpleasant smell when disturbed, often described as amaretto-like or skunk-like.
Compared to other roaches, the Florida woods cockroach is slower-moving and lacks the sleek, elongated body of species like the American cockroach. Its wingless, stout appearance and defensive odor are key identifiers.

The Florida woods cockroach stands out for its wingless, robust body, outdoor preference, and defensive spray. Unlike German or American roaches, it’s not a prolific indoor pest, but its odor and occasional indoor presence can be unsettling.
Florida Woods Cockroach Habitat
The Florida woods cockroach habitat is primarily outdoor, favoring warm, humid environments rich in organic matter. This species thrives in:
- Wooded Areas: Under tree bark, in tree cavities, or beneath fallen logs
- Palmetto Groves: Hiding under palmetto leaves, earning the “palmetto bug” nickname
- Leaf Litter: In piles of decaying leaves, mulch, or compost
- Woodpiles: Among stacked firewood or lumber
- Shaded Vegetation: Under dense shrubs or in garden beds
- Damp Locations: Near leaking pipes, standing water, or moist soil
In urban settings, Florida woods cockroaches may wander into sheds, greenhouses, or homes, especially in bathrooms or basements where moisture is abundant. They are cold-intolerant, restricting their range to subtropical and tropical climates like Florida, coastal Georgia, Alabama, Mississippi, and the West Indies. Their preference for stable, sheltered habitats makes them less likely to establish indoor colonies compared to other roaches.
Florida Woods Cockroach Behavior
The Florida woods cockroach behavior is distinct, shaped by its outdoor lifestyle and defensive adaptations. Key behaviors include:
- Nocturnal Activity: Active at night, foraging for food and mating while hiding in dark, damp spots during the day.
- Diet: Scavenges decaying plant matter, such as leaves, bark, moss, and wood, but may consume household scraps if indoors.
- Defensive Spray: When threatened, adults release a foul-smelling chemical from a gland beneath the abdomen, effective up to 1 meter. This spray deters predators and may signal other roaches to flee.
- Slow Movement: Unlike faster roaches, they move sluggishly, relying on their armored body and chemical defense rather than speed.
- Reproduction: Females produce oothecae, which they attach to surfaces like leaves or wood using a glue-like saliva. Each egg case contains 20–24 eggs, hatching in about 48–50 days. Nymphs molt 6–8 times over 4–6 months before reaching adulthood.
- Outdoor Preference: Rarely colonizes indoors, as they require high humidity and organic matter not typically found in homes.
This behavior makes the Florida woods cockroach less invasive but still a nuisance when it enters homes, especially due to its odor and large size.
Are Florida Woods Cockroaches Dangerous?
A common question is, are Florida woods cockroaches dangerous? While not as hazardous as indoor roaches, they pose some risks:
- Defensive Spray: The foul-smelling chemical can irritate skin and eyes in humans and pets. Nymphs release a sticky glue-like substance for defense.
- Allergens: Feces, shed skins, and body parts can trigger allergic reactions or asthma, especially in sensitive individuals, though this is rare due to their outdoor nature.
- Bacterial Contamination: While less likely to carry pathogens than German or American roaches, they can pick up bacteria from contaminated surfaces and spread it to food or utensils if indoors.
- Psychological Distress: Their large size, odor, and sudden appearance can cause anxiety or fear, particularly for those with katsaridaphobia (fear of cockroaches).
Compared to other roaches, Florida woods cockroaches are relatively harmless, as they don’t feed on filth or reproduce rapidly indoors. However, their presence can still be unsettling, and precautions should be taken to prevent entry.
Florida Woods Cockroach Infestation
A Florida woods cockroach infestation is rare indoors, as this species is not adapted to thrive in human dwellings. However, outdoor populations can grow near homes, leading to occasional indoor sightings. Signs of a potential infestation include:
- Sightings: Spotting large, dark roaches during the day, especially in damp areas like bathrooms or basements
- Droppings: Small, dark pellets in outdoor areas or near entry points
- Egg Cases: Brown or reddish oothecae in cracks, crevices, or outdoor debris
- Odor: A strong, unpleasant smell in areas where roaches are active
- Nymphs: Wingless, smaller roaches with yellow thoracic bands, indicating reproduction
Unlike German or American roaches, Florida woods cockroaches don’t form large indoor colonies. However, their rapid reproduction (females can produce hundreds of eggs in a lifetime) can lead to significant outdoor populations, increasing the likelihood of indoor encounters. Addressing outdoor habitats is key to preventing infestations.
How to Get Rid of Florida Woods Cockroach
If you’re wondering how to get rid of Florida woods cockroach, a combination of prevention, sanitation, and targeted control methods is most effective. Since these roaches are primarily outdoor pests, focus on both outdoor and indoor strategies:
Outdoor Control
- Remove Hiding Spots: Clear leaf litter, mulch, woodpiles, and yard debris at least 12–24 inches from your home’s foundation. Rake mulch away from the foundation and avoid heavy vegetation near walls.
- Manage Firewood: Store firewood on racks elevated off the ground and away from the house. Inspect wood before bringing it indoors.
- Reduce Moisture: Fix leaking pipes, sprinklers, or spigots. Eliminate standing water in yards or near outdoor structures.
- Trim Vegetation: Keep shrubs, trees, and grass trimmed to reduce shaded, damp areas where roaches hide.
Indoor Prevention
- Seal Entry Points: Use caulk or weatherstripping to close gaps around doors, windows, pipes, and vents. Ensure screens on windows and vents are intact.
- Sanitation: Keep kitchens and bathrooms clean, storing food in airtight containers and promptly cleaning spills or crumbs. Vacuum regularly to remove potential allergens like roach feces or skins.
- Inspect Items: Check groceries, plants, or outdoor items for roaches before bringing them inside.
Control Methods
- Traps: Use homemade traps, such as a jar with a beer-soaked piece of bread and a greased inner lip, placed against walls. Roaches climb in but cannot escape.
- Baits: Apply granular cockroach baits in outdoor areas like flowerbeds or ground cover. Boric acid baits can be placed under sinks or in cabinets, but use caution around pets and children.
- Insecticides: Liquid insecticides can create a barrier around the home’s foundation, reapplied periodically as sun and rain degrade them. Ground silica gel or insect growth regulators can be used in cracks and crevices to dehydrate or disrupt roach reproduction.
- Professional Pest Control: For persistent issues, hire a licensed exterminator. Professionals use eco-friendly methods, such as targeted baits and sprays, and can vacuum up roach carcasses and egg cases to sanitize affected areas.
Since Florida woods cockroaches are slow-moving and unlikely to infest indoors, individual roaches can often be removed manually and released outside. Consistent outdoor maintenance is the most effective long-term solution.
