Brown-banded cockroaches
Brown-banded cockroaches (Supella longipalpa), often called light brown cockroaches or brown cockroaches, are pests that thrive in homes, offices, and other indoor environments.
Unlike other roach species, such as the American or German cockroach, brown-banded roaches prefer drier areas and avoid moist, humid spaces. This makes them unique and sometimes more challenging to control, as they often hide in less obvious places, such as attics, bedrooms, or living rooms, rather than kitchens and bathrooms.
First recorded in North America in the early 20th century, brown-banded cockroaches have now spread across the continent. Their ability to thrive in dry, warm conditions makes them a common concern for homeowners and business owners alike.
These light brown cockroaches can quickly establish themselves in homes or commercial spaces, hiding in furniture, behind picture frames, and even within electronic devices.
Characteristics
Brown-banded cockroaches are relatively small, measuring about ½ an inch to ⅝ of an inch when fully grown.
A distinguishing feature is the two light brown or yellowish bands that stretch across their wings and abdomen, giving these particular cockroaches their name. These bands are present in adult males and females, but adult males have more pronounced wings extending beyond the tip of their abdomen, enabling them to glide short distances. Adult females, on the other hand, have shorter wings and are darker in color.
Brown-banded cockroach nymphs (juveniles) also exhibit the characteristic bands across their bodies but lack fully developed wings. They are fast movers and can hide in various dry, warm spaces.
Eradicating brown-banded cockroaches can be a challenge, as these pests are resilient. Learn more about getting rid of cockroaches.
Identification
Identifying brown-banded cockroaches is essential to choosing the right pest control strategy. The two light brown bands across their wings and abdomen are their distinguishing feature, separating them from other roach species.
Adult brown-banded roaches are smaller than American cockroaches but slightly larger than German cockroaches. Males are generally more active and capable of gliding short distances.
A key trait that differentiates brown-banded cockroaches from others is their habitat preference. While other species gravitate toward moist areas like kitchens and bathrooms, brown-banded roaches prefer drier areas like living rooms, bedrooms, and attics. They tend to hide in high places like inside furniture, behind picture frames, and even within electronics, making them more difficult to detect.
The life cycle of a brown-banded cockroach takes around 90 to 270 days, depending on the environment's temperature. A female cockroach usually carries an egg capsule for 24-36 hours and then attaches it to surfaces in hidden areas. The capsule contains about 13-16 eggs which incubate for 50-75 days before hatching.
Proper identification is the first step in implementing targeted control measures, as the size, behavior, and breeding habits of brown-banded cockroaches differ from those of other roaches like German or American cockroaches. Recognizing these characteristics early on is essential for preventing a full-blown infestation.

Habitat
Brown-banded cockroaches are highly adaptable and thrive in dry, warm environments.
Unlike other cockroach species that prefer humid areas, brown-banded cockroaches are more likely to be found in bedrooms, living rooms, or attics. They often hide in high, concealed places, such as behind picture frames, inside clocks, or within the crevices of furniture.
These roaches may also infest electronic devices, using the warmth and shelter provided by these devices to hide and breed. This behavior can lead to damage, as their waste and secretions may interfere with the operation of electronics.
The versatility of their preferred habitats makes them particularly challenging to eliminate. Brown-banded cockroaches can quickly spread infestations through walls, air ducts, and electrical outlets in multi-unit housing complexes or commercial buildings.
Brown-banded cockroaches in America
First reported in the United States in the early 1900s, brown-banded cockroaches likely arrived through international trade. Since then, they have spread across much of North America, particularly in warmer regions such as the southern United States, where the dry, warm climate aligns with their preferences.
Brown-banded cockroaches are typically found indoors in cooler climates, using heated homes and offices as shelter. Their survival ability in less humid environments gives them a competitive advantage over other cockroach species that rely on moisture.
Infestations are widespread in urban areas, where cockroaches can easily spread between neighboring buildings. Older buildings with cracks and structural damage provide ideal hiding spots for brown-banded roaches, making infestations even more difficult to detect and control.
Brown-banded cockroach behaviors, threats, or dangers
Brown-banded cockroaches are nocturnal and prefer to hide during the day, making it challenging to spot an infestation early. They are highly agile and capable of squeezing into small cracks and crevices, which helps them avoid detection.
When food sources are limited, brown-banded cockroaches feed on starch-based materials, such as glue, wallpaper paste, and book bindings. They also scavenge for human food scraps, pet food, and organic waste, posing a potential health risk.
Brown-banded cockroaches are known carriers of bacteria and pathogens like roach species. As they move through an environment, they can spread harmful microbes, including E. coli and Salmonella, which can contaminate food and surfaces, leading to foodborne illnesses.
Their droppings and shed skin can also trigger allergic reactions and asthma attacks, particularly in children or individuals with respiratory issues.
Are brown-banded cockroaches hard to get rid of?
Yes, brown-banded cockroaches can be quite difficult to eliminate. They can hide in high, dry areas, such as behind furniture or inside electronics, and remain undetected for long periods. By the time an infestation is discovered, their population may have multiplied, making them harder to control.
DIY methods, such as setting traps or applying insecticides, may provide temporary relief, but these approaches often fail to address the full extent of an infestation. Learn more about the steps you can take to get rid of cockroaches.
Professional pest control services are usually necessary to thoroughly assess the infestation, locate all potential hiding spots, and treat both adult cockroaches and their eggs. Integrated pest management techniques, including baits and residual insecticides, are often the most effective for complete eradication. If you suspect a cockroach infestation, contact Ehrlich today!
Is one brown-banded cockroach an infestation?
Seeing a single brown-banded cockroach can be an early sign of a larger infestation. These cockroaches are social creatures, hiding in groups and nesting in hard-to-reach areas. Because they are nocturnal, it's unlikely that you will spot many during the day, but their activity at night may indicate a growing infestation.
Brown-banded cockroaches reproduce quickly. A single female can produce numerous offspring within a few months, leading to a significant population increase if the problem is left untreated.
If you spot a brown-banded cockroach in your home, it’s essential to act quickly. Conduct a thorough inspection, paying close attention to dry areas where food and shelter are accessible. If additional cockroaches are found, consider contacting a professional pest control service to address the issue before it worsens.
Frequently asked questions
Why do I have brown-banded roaches?
You likely have brown-banded cockroaches because your home provides a dry, warm environment with accessible food and shelter. These pests may enter homes or businesses through cracks and crevices or be brought in via packages or second-hand furniture. Poor sanitation, clutter, and food waste can also contribute to an infestation.
What kills brown-banded roaches?
Residual insecticides, bait traps, and roach-specific treatments can kill brown-banded cockroaches. However, due to their tendency to hide in hard-to-reach areas, professional pest control treatments are often the most effective option for completely eradicating an infestation.
Where do brown-banded cockroaches like hiding?
Brown-banded cockroaches typically hide in warm, dry places such as behind furniture, inside electronics, or behind picture frames. They are often found in attics, living rooms, and bedrooms, away from the moisture-rich environments preferred by other cockroach species.
Do brown-banded cockroaches live outside?
While brown-banded cockroaches primarily prefer indoor environments, they can occasionally be outdoors in warm, dry climates. However, they are more commonly found in homes or businesses with access to food, warmth, and shelter.
