Question 1
During a structural inspection you collect a winged insect from a swarm. Which single feature would confirm it is a termite rather than an ant?
- A broad waist and two pairs of equal-length wings
- Elbowed antennae and a sharply pinched, narrow waist
- Front wings that are clearly longer than the hind wings
- A hard outer shell divided into three distinct segments
Show answer & explanation
Correct answer: A - A broad waist and two pairs of equal-length wings
Question 2
Beneath a wooden window sill that has no soil contact and shows no mud tubes, you find small piles of hard, six-sided fecal pellets. These findings are MOST characteristic of:
- Subterranean termites
- Dampwood termites
- Drywood termites
- Carpenter ants
Show answer & explanation
Correct answer: C - Drywood termites
Question 3
On a California Wood Destroying Pests and Organisms Inspection Report, an earth-to-wood contact with no current damage but likely to lead to future infestation is recorded as a:
- Section I finding, because any earth-to-wood contact is active
- Diagram notation only, with no written section entry needed
- Item that is omitted until actual damage can be confirmed
- Section II finding, a condition likely to lead to infestation
Show answer & explanation
Correct answer: D - Section II finding, a condition likely to lead to infestation
Question 4
A kitchen has a heavy infestation of small ants identified as Pharaoh ants. Why is broadcast spraying with a residual insecticide the WRONG first approach?
- Pharaoh ants are a protected species that may not legally be sprayed
- It splits the colony, which buds and scatters into new nests
- Residual sprays carry no label allowance for any indoor ant work
- These ants are already resistant to every registered insecticide
Show answer & explanation
Correct answer: B - It splits the colony, which buds and scatters into new nests
Question 5
Two products are on your truck. Product A has an oral LD50 of 30 mg/kg; Product B has an oral LD50 of 1,200 mg/kg. Which statement is correct?
- Product A is more acutely toxic and would carry the word DANGER
- Product B is more acutely toxic and would carry the word DANGER
- Both carry the same signal word because both are pesticides
- LD50 rates effectiveness, not toxicity, so neither is more hazardous
Show answer & explanation
Correct answer: A - Product A is more acutely toxic and would carry the word DANGER
Question 6
Sulfuryl fluoride, a common structural fumigant, is odorless and colorless. For this reason California fumigations require the release of chloropicrin, which functions as a:
- Secondary fumigant added to boost the overall lethal kill rate
- Warning agent that irritates the eyes to force evacuation
- Neutralizing agent that speeds up aeration after exposure
- Sealant additive that helps the tarps hold in the gas
Show answer & explanation
Correct answer: B - Warning agent that irritates the eyes to force evacuation
Question 7
Under California rules for structural fumigation, the licensed fumigator must be physically present at all of the following times EXCEPT:
- While the fumigant is actively being released into the structure
- At the time ventilation (aeration) of the structure is commenced
- During the sealed exposure period while no one is on the site
- At the time the structure is released for reoccupancy by people
Show answer & explanation
Correct answer: C - During the sealed exposure period while no one is on the site

- Perform pest control work only for a registered company
Show answer & explanation

- Increase the subarea ventilation elsewhere in the structure
- Treat only the surrounding soil with a residual termiticide
Show answer & explanation
Correct answer: A - Separate the wood from the soil, e.g., on a concrete base
