ACE ACE Urban & Structural Pest Management 2 — Questions and Answers
Question 1: Which rodent is known for its ability to fit through a hole as small as 1/4 inch in diameter?
- Norway rat (Rattus norvegicus)
- Roof rat (Rattus rattus)
- House mouse (Mus musculus) (Correct answer)
- Deer mouse (Peromyscus maniculatus)
Correct answer: House mouse (Mus musculus)
The house mouse can squeeze through openings as small as 1/4 inch (6 mm) due to its flexible skeletal structure.
Question 2: Which of the following best describes the nesting preference of the Norway rat?
- Prefers elevated areas like attics and upper cabinets
- Burrows in the ground near foundations and walls (Correct answer)
- Nests inside wall voids near electrical wiring
- Lives exclusively in sewers and does not enter buildings
Correct answer: Burrows in the ground near foundations and walls
Norway rats are burrowing rodents that typically nest in underground burrows near building foundations.
Question 3: In urban pest management, 'crack and crevice' application refers to:
- Applying pesticides broadly across floors and walls
- Directing pesticide into tight spaces where pests harbor (Correct answer)
- Spraying perimeter foundations during rain
- Injecting pesticide into deep soil near tree roots
Correct answer: Directing pesticide into tight spaces where pests harbor
Crack and crevice treatment targets pesticides into voids and gaps where pests rest and breed, minimizing non-target exposure.
Question 4: Which cockroach species is commonly found outdoors and is considered a peridomestic pest?
- German cockroach
- Brown-banded cockroach
- American cockroach (Correct answer)
- Asian cockroach
Correct answer: American cockroach
The American cockroach (Periplaneta americana) is a peridomestic species that lives outdoors but readily enters buildings.
Question 5: What is the primary purpose of an insect light trap (ILT) in a food-handling facility?
- To attract and kill flying pest insects near food prep areas (Correct answer)
- To measure humidity levels that attract stored product pests
- To sterilize air and kill airborne bacteria
- To lure and capture crawling insects like cockroaches
Correct answer: To attract and kill flying pest insects near food prep areas
ILTs use UV light to attract flying insects, which are then captured on a sticky board or electrocuted, helping monitor and reduce fly populations.
Question 6: Carpenter ants (Camponotus spp.) differ from termites primarily in that carpenter ants:
- Eat wood for nutrition
- Excavate wood for nesting but do not eat it (Correct answer)
- Produce mud tubes along foundation walls
- Live entirely in the soil and never enter structures
Correct answer: Excavate wood for nesting but do not eat it
Carpenter ants tunnel through wood to create nesting galleries but do not consume wood as food, unlike termites.
