Brown-banded Cockroach

The brown-banded cockroach, Supella longipalpa is a small cockroach (10-15 mm) that can be seen in tropical and subtropical regions of the world. It is commonly found in homes, apartments, hotels and hospitals and less frequently in stores, restaurants and kitchens. The brown-banded cockroaches do not require as much moisture as the German cockroach, Blattela germanica, so they are normally found in rooms other than those containing wet areas such as kitchens or bathrooms. This widespread habitat of the brown-banded cockroach makes them very difficult to control.

Brown-banded cockroach enter buildings during the dry warm months of the year. These insects feed on clothing and papers particularly those stained by food and perspiration. Females pack their eggs in a tough leathery capsule called an ootheca and glue them with saliva to a surface, often inside a dark drawer or cupboard. Then they conceal the egg case with bits of debris or excrement. The deposition and concealment may take several hours. The egg case is about 4-5 mm in length and contains about 16 eggs. After fourty days, the eggs hatch.3

This cockroach species carries a variety of microorganisms, as a vector for pathogenic bacteria in urban environments and it has also been reported as a source of allergens. Bacteria isolated from this species include: Enterobacteria, Klebsiella, Citrobacter, Escherichia coli, Salmonella spp., Proteus, Salmonella, Serratia, Staphylococcus, and Bacillus. The brown-banded cockroach is involved in the spread of drug resistant bacteria and increases the possibility of contacting human environment to drug resistant bacteria.
