Brown-banded Cockroach (Supella longipalpa)

Identification: Adult size 11-15mm; this cockroach is small, light brown in colour and is often mistaken for the German cockroach.

Brown-banded cockroaches get their name from the light brown or tan transverse bands that are present on the wings of the adult and across the body of the nymphs.

This cockroach needs hot conditions to survive, it prefers 27°C and over. It is typically found in light switches, electrical appliances, motor housings, etc in multi occupancy accommodation such as student accommodation in Universities.

They prefer to hide in warm, elevated areas near the ceiling, behind wall decorations and loose wallpaper, in closets, beneath or inside upholstered furniture, and in electrical appliances such as TV sets, stereos, radios, and toasters.

Biology: Brown banded cockroach females deposit egg cases in clusters on furniture, draperies, wall decorations, shelving and ceilings. The egg capsule contains 14 to 16 eggs; a female produces 10 to 20 cases in her lifetime. Eggs hatch in 50 to 75 days and nymphs develop in 90 to 270 days, with adults living 150 to 200 days.

Control: Effective treatment depends upon the selection and thorough application of a suitable insecticide. Many insects and egg cases are well hidden; therefore, the insecticide must be placed at and around these harbourages and maintained over the developmental period of the particular species. To control an infestation the insecticide should ideally persist until all egg cases have hatched but continued immigration may demand routine treatments.

A high standard of hygiene is important in the control of cockroaches and involves the following components: Deny access to food and water Deny access to harbourages in buildings or equipment. Practice improved hygiene Monitoring of incoming materials including packaging and laundry.

Use biocides safely. Always read the label and product information before use.
