Brown-banded Cockroach

What is the brown-banded cockroach?

 Scientific name: Supella longipalpa

Family: Ectobiidae

Order: Blattodea

Risk level: Moderate

Category: Insect

The brown-banded cockroach (Supella longipalpa) is the smallest common household cockroach, measuring 13–14.5 mm. It is identified by two distinct light-brown transverse bands across its wings and abdomen. Unlike other cockroaches, it prefers warm, dry environments rather than damp ones. It tends to hide in elevated places, including inside furniture, books and electronic devices, rather than near water sources.

Life cycle of the brown-banded cockroach

The female lays 14 oothecae, each containing 13–18 eggs, and attaches them inside cavities. Nymphal development takes 8–31 weeks. Adults live for 13–45 weeks.

Distribution of the brown-banded cockroach

It is widespread in hot and tropical regions and can spread through used furniture and electronic equipment.

Health risks and related problems

It is a mechanical carrier of intestinal pathogens. Its presence inside electronic equipment poses a risk to data archives and medical devices in hospitals.

Signs of a brown-banded cockroach infestation

Signs include eggs attached behind furniture and wooden frames; small droppings in drawers and cabinets; and sightings in high areas of walls or inside televisions and other electrical equipment.

Where brown-banded cockroaches are found

They hide in furniture cavities, behind picture frames, inside electrical and electronic equipment, among the folds of books and magazines, and behind plasterboard panels away from water.

Brown-banded cockroach control methods

Treat furniture and storage areas, not just the kitchen. Place gel baits in hiding places and use IGR baits to prevent reproduction. Carefully inspect used furniture before bringing it indoors.

Brown-banded cockroach control products

Gel baits (imidacloprid/hydramethylnon), IGRs and diatomaceous earth in furniture cavities.

Requirements for controlling brown-banded cockroaches in food facilities

FSSC/BRCGS: include this pest in the pest-control plan. Its presence in a packaging area or on factory equipment requires an immediate investigation.

A fact about the brown-banded cockroach

The brown-banded cockroach is one of the most difficult cockroaches to control because it spreads throughout a room instead of gathering only near water and food. A thorough inspection of the room’s contents is therefore required.

Frequently asked questions about the brown-banded cockroach

Q: How does the brown-banded cockroach enter buildings?

A: It often arrives in used furniture, cardboard boxes and electronic equipment. Used purchases should be inspected carefully.

Q: Why does it appear inside televisions and other devices?

A: It is attracted to the warmth of electronic devices and their dry environment. The devices themselves need to be treated, not just the walls and floors
