Adult Brown-Banded Cockroach
Brown-Banded Male Cockroach
Brown-Banded Female Cockroach
- Size: About 1.1 to 1.5 cm long
- Color: Light brown with darker bands

- Detection Element: Insects mainly living in dry areas, such as upholstered furniture, behind picture frames, under electronic devices.
The brown-banded cockroach is a small domestic insect recognized by its size, varying between 10 and 14 mm, and its flat and oval body. This shape allows them to slip into narrow spaces. Their color is primarily dark brown, but what really distinguishes them are the light brown or yellowish bands marking their pronotum, the structure that protects the head.
Regarding their wings, there is a noticeable difference between the sexes. Males have wings that fully cover the body and extend slightly beyond the abdomen, while females have shorter wings that do not completely cover the abdomen. Despite their ability to fly, these cockroaches prefer to run or climb to move around. Their behavior is mainly nocturnal, and they tend to avoid light.
The long antennae of the brown-banded cockroach, composed of many segments, are another characteristic feature, giving them great sensitivity to environmental stimuli. They are often found indoors, particularly in warm and humid places like kitchens and bathrooms. Recognizing these characteristics is crucial to distinguish them from other cockroach species and to adopt appropriate management measures in case of infestation.
Brown-Banded Cockroach Nymph
Brown-Banded Cockroach Nymph
- Size: About 0.2 to 1 cm long
- Color: Generally more uniformly dark brown
- Distinctive Feature: Lack of wings, more rounded body
- Habitat: In dry areas, such as upholstered furniture, behind picture frames, under electronic devices.
The nymphs of the brown-banded cockroach, although similar to adults, are distinguished by several features. Smaller in size, measuring between 2 and 10 mm depending on their stage of development, they lack functional wings, although wing buds may be observed in advanced stages of their growth. Their coloration varies from light brown to dark brown, with indications of bands on the pronotum, although these are less pronounced than in adults.
During their development, nymphs undergo several molts, gradually increasing in size. They share with the adults a preference for warm and humid environments and a predominantly nocturnal lifestyle. The presence of nymphs often indicates an active infestation, as they generally remain close to their birthplace. Their identification is crucial for effective intervention against infestations, requiring an interruption of their life cycle.
Brown-banded cockroaches are often found in human buildings, such as houses, apartments, hotels, and healthcare facilities. They prefer warm and dry places, unlike other species that seek moisture. They are frequently found in furniture, behind picture frames, in electrical appliances, and even in wall cracks or baseboards. Their ability to live in dry environments means they can establish themselves in rooms other than kitchens or bathrooms, such as bedrooms and living rooms.
Distinguishing Brown-Banded Cockroaches from Other Insects
The brown-banded cockroach is distinguished from the German cockroach by its size and markings. The German cockroach is smaller, typically measuring between 13 and 16 mm, and has a paler coloration. It has two dark longitudinal bands on its pronotum. German cockroaches are also faster and more agile, often found in humid areas such as kitchens and bathrooms.
The American cockroach is significantly larger than the brown-banded cockroach, reaching up to 40 mm in length. It is reddish-brown in color with a shiny pronotum. The American cockroach prefers warm and humid environments but is more commonly found in places like basements and sewers, unlike the brown-banded cockroach which favors indoor living spaces.
The red flour beetle, a common pest of stored products, differs significantly from the brown-banded cockroach. It is much smaller, measuring about 4 mm in length, and has a uniform reddish-brown color without distinctive markings. It is primarily found in grain products like flour, where it feeds and reproduces, unlike the brown-banded cockroach which has a more varied diet and habitats.
Bed bugs are very different from brown-banded cockroaches. They measure about 5 mm in length, are oval and flattened in shape, and reddish-brown in color. They do not have wings and are known for their habit of feeding on human blood. Bed bugs often hide in beds or furniture and are mainly active at night. They do not have the same markings as the brown-banded cockroach and have very distinct lifestyles and feeding habits.
