Sample questions
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
Show 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.🔗 Source
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
Show 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.🔗 Source
What is a notable biological difference between male and female brown-banded cockroaches?
- Males are shorter-winged and darker than females.
- Females are capable of flight, while males cannot.
- Males have wings that reach over the abdomen, while females are shorter-winged and cannot fly.
- Males are roughly half an inch long, while females are only 13mm.
Show answer
The sexes differ too: a male's wings reach over the abdomen, while the broader, darker female is shorter-winged... Adult males can fly when warm; females cannot.🔗 Source
Which of the following is a recognized health risk associated with brown-banded cockroach infestations?
- They cause structural damage to building foundations.
- They are primary pollinators for indoor plants.
- Their residue can flare up allergy and asthma symptoms, especially in children.
- They are beneficial decomposers in residential settings.
Show answer
The residue a roach leaves behind — bits of its saliva, droppings, and molted skins — can flare up allergy and asthma symptoms, with children most affected.🔗 Source
In terms of treatment strategy, what should an applicator do before applying broad chemical treatments?
- 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.
Show 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.🔗 Source
What is the estimated reproductive potential of a single female brown-banded cockroach in one year?
- Approximately 14 eggs total
- About 14 capsules containing 14-18 eggs each
- Over 600 roaches when including offspring
- Approximately 160 roaches
Show answer
It adds up fast: one female and her offspring can yield over 600 roaches in a year.🔗 Source
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.
Show 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.🔗 Source
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.
- They favor warm, dry, and elevated spots throughout a building.
- They exclusively reside under kitchen cabinets and sinks.
Show answer
A small indoor cockroach that favors warm, dry, elevated spots throughout a building... unlike most relatives, favors dry, warm, high spots and scatters all over a home instead of staying under the kitchen sink.🔗 Source
