What Are Brown Banded Cockroaches?

Brown-banded cockroaches (Supella longipalpa) are a species of small cockroach commonly found in households and commercial spaces. They are one of the most common cockroach species in the United States and can be found in many other parts of the world. Here is an overview of brown-banded cockroaches:

  • Identification: Brown-banded cockroaches are relatively small, measuring about 10 to 14 mm in length. They are light brown to dark brown in color and are distinguished by two distinctive, light-colored bands running across their wings and abdomen, which give them their name. These bands are more pronounced in nymphs (young cockroaches) and may fade in adults.

  • Habitat: Unlike the more well-known German cockroach and American cockroach, brown-banded cockroaches prefer drier and warmer environments. They are often found in areas where there is less moisture, such as high up on walls, ceilings, inside cabinets, and furniture. They tend to avoid kitchens and bathrooms, instead favoring bedrooms, living rooms, and other areas with less humidity.

  • Diet: Brown-banded cockroaches are omnivorous and will eat a wide range of materials, including starchy and sugary foods, cardboard, glue, book bindings, and even dead insects. They can survive on very limited food sources, making them adaptable to various environments.

  • Reproduction: Like other cockroach species, brown-banded cockroaches reproduce quickly. A female can produce up to 14 egg capsules in her lifetime, with each capsule containing around 10 to 18 eggs. These capsules are often hidden in cracks and crevices, making them difficult to find and eradicate.

  • Health Concerns: Brown-banded cockroaches, like their counterparts, can pose health risks to humans. They can carry pathogens and allergens, potentially leading to diseases and respiratory issues. Their droppings and shed skins can trigger allergies in sensitive individuals.

  • Control and Prevention: Controlling brown-banded cockroaches requires a comprehensive approach. It involves eliminating food sources, sealing cracks and crevices where they hide, and implementing effective insecticides or baits. Due to their propensity for hiding in hard-to-reach places, professional pest control may be necessary for complete eradication.

Brown-banded cockroaches are a common household pest known for their distinctive banding and preference for drier environments. Understanding their habits, habitat, and biology is essential for effective control and prevention. If an infestation is suspected, it's advisable to consult with a pest control professional for thorough and expert assistance.

What Do Brown Banded Cockroaches Look Like?

Brown-banded cockroaches (Supella longipalpa) have distinct features that set them apart from other cockroach species. Here's a description of what they look like:

  • Size: Brown-banded cockroaches are relatively small compared to other common cockroach species. They typically measure between 10 to 14 millimeters (about 0.4 to 0.55 inches) in length.
  • Color: These roaches are light to dark brown in color. They have a glossy appearance with a somewhat shiny exoskeleton.
  • Bands: The most distinctive feature of brown-banded cockroaches is the two light-colored bands that run across their bodies, which gives them their name. One band stretches across their wings, and the other is located at the base of the abdomen. These bands are more prominent in nymphs (young cockroaches) and may become less distinct in adult individuals.
  • Antennae: Brown-banded cockroaches have long, slender antennae that are often longer than their bodies. These antennae play a crucial role in sensing their environment and locating food sources.
  • Wings: These roaches have fully developed wings but are not strong fliers. Their primary mode of movement is running, and they are often more agile on the ground.
  • Size Differences: Males and females of this species look very similar in terms of color and banding, but there are slight differences in size. Males tend to have longer wings and are generally smaller than females.
  • Nymphs: Nymphs (young brown-banded cockroaches) are smaller and lighter in color than adults. Their bands are often more pronounced, making them easier to identify.

Brown-banded cockroaches are characterized by their small size, light to dark brown coloration, and the two distinctive bands across their bodies. These bands are the key identifying feature that separates them from other cockroach species, making them relatively easy to recognize when seen in your home or other environments.

Where Are Brown Banded Cockroaches Found?

Brown-banded cockroaches (Supella longipalpa) have specific habitat preferences that differ from other cockroach species. Here's where you might find brown-banded cockroaches:

  • Indoors: Brown-banded cockroaches are primarily indoor pests and are often found in residential and commercial buildings. They prefer drier and warmer conditions, and unlike some other common cockroach species, they tend to avoid areas with high humidity. You can find them in various indoor locations, including:
    1. Bedrooms: Brown-banded cockroaches often hide in and around bedroom furniture, closets, and wall hangings.
    2. Living Rooms: They can be found in upholstered furniture, behind picture frames, and inside electrical outlets.
    3. Office Spaces: These cockroaches may infest office buildings, especially in areas with a lack of humidity, like storage rooms or bookshelves.
    4. Cabinets: They may infest kitchen and bathroom cabinets, especially if these spaces are less humid than other areas of the home.
  • High Locations: Unlike many other roaches, brown-banded cockroaches tend to hide in higher locations. You may find them in ceilings, upper cabinets, and near light fixtures.
  • Electrical Appliances: They are known to hide in and around electrical appliances, such as TVs, radios, and even inside refrigerator motors.
  • Cracks and Crevices: Brown-banded cockroaches are skilled at hiding in small cracks and crevices, making them challenging to spot and eliminate. They can squeeze into tiny spaces, which can be behind baseboards, in wall voids, or within furniture.
  • Transported Items: These roaches can also be inadvertently introduced into new areas through infested items such as furniture or boxes.
  • Warm and Dry Regions: While they can be found in various parts of the world, brown-banded cockroaches are more common in warmer, drier regions where they can thrive due to their preference for lower humidity.

Brown-banded cockroaches are most often found indoors, especially in rooms and spaces with lower humidity. They tend to hide in high places and small cracks and crevices, making them challenging to detect and control. If you suspect an infestation, it's essential to thoroughly inspect your home or commercial space to locate their hiding spots and take appropriate pest control measures.

What Is The Life Cycle Of Brown Banded Cockroaches?

The life cycle of brown-banded cockroaches (Supella longipalpa) is similar to that of other cockroach species and consists of several stages, including egg, nymph, and adult. Here is the life cycle of brown-banded cockroaches:

Egg Stage:

The life cycle begins with the female brown-banded cockroach laying egg capsules. These capsules, also known as oothecae, are protective cases that contain multiple eggs. Each ootheca typically contains 10 to 18 eggs. The female deposits the ootheca in a concealed location, such as in cracks and crevices, or hidden within furniture. The female brown-banded cockroach can produce multiple oothecae throughout her lifetime.

Nymph Stage:

After a few weeks, the eggs within the ootheca hatch, releasing nymphs. Nymphs are young, immature cockroaches that resemble adults but are smaller and lack fully developed wings. Nymphs go through several stages of development, shedding their exoskeletons, or molting, as they grow. During each molt, they develop more adult-like features. Brown-banded cockroach nymphs are highly active and require food and water to support their growth. The duration of the nymph stage varies but typically takes a few months.

Adult Stage:

Once the nymphs complete their development through several molts, they reach the adult stage. Adult brown-banded cockroaches are fully developed and capable of reproducing. They are about 10 to 14 millimeters (0.4 to 0.55 inches) in length, have fully developed wings, and display the characteristic light bands on their bodies.


Adult male brown-banded cockroaches are smaller than females and have longer wings. They produce spermatophores, which are small packets of sperm. The males deposit spermatophores on various surfaces. Females pick up spermatophores to fertilize their eggs, and they use these fertilized eggs to create new oothecae.

Life Span:

The entire life cycle of a brown-banded cockroach, from egg to adult, can typically take several months, depending on environmental conditions and available food and water. Brown-banded cockroaches are known for their rapid reproductive rates, with a single female producing multiple oothecae during her lifetime.

The life cycle of brown-banded cockroaches can be influenced by factors such as temperature, humidity, and food availability. In ideal conditions, they can reproduce quickly, making infestations a concern in homes and other indoor spaces. Effective pest control measures are necessary to manage and prevent infestations of these pests.

What Do Brown Banded Cockroaches Eat?

Brown-banded cockroaches (Supella longipalpa) are opportunistic feeders, which means they can consume a wide range of materials. Their diet is similar to that of many other cockroach species and is influenced by their scavenging behavior. Here is what brown-banded cockroaches eat:

  • Starchy and Sugary Foods: Brown-banded cockroaches have a preference for starchy and sugary foods. They readily consume items such as cereals, grains, bread, pasta, and sweet foods like cookies, candies, and syrups.
  • Cardboard and Paper: These cockroaches are known to feed on cardboard, paper, and book bindings. They are attracted to the glues and adhesives found in these materials.
  • Dead Insects: Brown-banded cockroaches are opportunistic scavengers, and they may feed on dead insects or other small invertebrates when they come across them.
  • Pet Food: If you have pets, brown-banded cockroaches might be attracted to and feed on pet food, especially if it's left out in open containers.
  • Human Food Scraps: They are not selective when it comes to human food scraps. Leftover crumbs, spilled food, and even grease can be a food source for them.
  • Organic Matter: These roaches can feed on a variety of organic matter, including decaying plant material, fungi, and small bits of food waste.
  • Water: While not a direct food source, brown-banded cockroaches require water for survival. They often obtain moisture from the food they consume or from condensation on pipes and surfaces.

Brown-banded cockroaches have a relatively broad diet, and their ability to thrive on limited food sources makes them adaptable to various environments. To prevent and control infestations, it's crucial to keep living spaces clean, store food in airtight containers, and eliminate food and water sources that might attract these pests. Additionally, using effective pest control methods and sealing entry points can help manage brown-banded cockroach populations.
