Brown-banded Cockroach

When differentiating the brown-banded cockroach from the German cockroach during an inspection, which anatomical feature is a distinguishing characteristic?

• The presence of two dark lengthwise stripes on the pronotum
• A clear and unmarked pronotum edge ✓
• Wings that reach over the abdomen
• A darker, shorter-winged body shape

Answer: A useful tell is the pronotum (the shield behind the head): on this roach its edge is clear and unmarked. The look-alike German cockroach, by contrast, carries two dark lengthwise stripes there.

During an inspection, which finding is considered the clearest evidence of an active brown-banded cockroach population and harborage?

• A single wandering insect near a floor level
• The presence of two dark stripes on the pronotum
• Quarter-inch egg capsules glued in hidden spots like under drawers or inside electronics ✓
• Finding the roaches exclusively in the kitchen sink area

Answer: The clearest evidence is the quarter-inch egg cases glued in hidden spots — under drawers and furniture and inside appliances and electronics — which point straight to harborage.

• Apply perimeter sprays immediately upon sighting a single insect.
• Confirm the species and map the harborage. ✓
• Focus only on the kitchen and bathroom areas.
• Wait for the outdoor season to end.

Answer: Confirm the species and map harborage before treating; this roach is notoriously hard to control with baits and hides in scattered spots, so treatment must be thorough and aimed at population sources.

An applicator is treating a building and finds the brown-banded cockroach is difficult to control. According to the text, what is a primary reason for this difficulty?

• The species is a structural pest that destroys wood.
• Harborage is scattered and they are notorious for being hard to control with baits. ✓
• They only breed during specific outdoor seasons.
• They require high moisture to survive, making bait ineffective.

Answer: Professional Recommended: yes when confirmed indoors — harborage is scattered and baiting is difficult... this roach is notoriously hard to control with baits and hides in scattered spots.

Which of the following describes the typical habitat preference of the brown-banded cockroach compared to other roach species?

• They prefer moist environments like kitchen and bathroom sinks.
• They prefer dark, damp areas in restaurants and stores.
