California Branch 3 Field Representative Exam for Wood
Destroying Organisms | Latest Verified Questions and
Detailed Answers
OVERVIEW DESCRIPTION
This comprehensive set of multiple choice questions is designed for the California
Branch 3 Field Representative Exam for Wood Destroying Organisms, administered by
the Structural Pest Control Board (SPCB) and delivered through PSI. The actual exam
is a closed-book, multiple-choice test divided into two primary sections:
Technical/Entomology and Law/Rules/Safety. It thoroughly assesses a candidate’s
ability to identify wood-destroying organisms (termites, beetles, fungi), conduct proper
inspection procedures and report writing using the standard WDO form, apply pesticide
safety and equipment protocols, and correctly interpret the Structural Pest Control Act
and associated regulations.
SECTION 1: TECHNICAL/ENTOMOLOGY
QUESTION 1
Which of the following is a characteristic that distinguishes termite swarmers from ant
swarmers?
A. Ants have four equal-sized wings
B. Termites have a pinched waist
C. Ants have elbowed antennae
D. Termites have a narrow pedicel between thorax and abdomen
CORRECT ANSWER: C. Ants have elbowed antennae
EXPERT RATIONALE: Ants possess elbowed antennae and a constricted waist, whereas
termite swarmers have straight, bead-like antennae and a broad waist.
QUESTION 2
Subterranean termites build shelter tubes primarily to:
,2|Page
A. Store food reserves
B. Protect themselves from predators and maintain moisture
C. Signal the location of the colony
D. Deposit frass away from the nest
CORRECT ANSWER: B. Protect themselves from predators and maintain moisture
EXPERT RATIONALE: The tubes shield termites from dry air and enemies while they
travel between soil and wood.
QUESTION 3
Drywood termite pellets (frass) are best described as:
A. Smooth, oval, shiny grains
B. Fine, talc-like powder
C. Hard, six-sided pellets with concave surfaces
D. Coarse, fibrous shreds
CORRECT ANSWER: C. Hard, six-sided pellets with concave surfaces
EXPERT RATIONALE: Drywood termites push hexagonal fecal pellets out of kick-out
holes; the pellets are gritty and distinct.
QUESTION 4
A dampwood termite colony requires wood with a moisture content typically above:
A. 5%
B. 12%
C. 20%
D. 30%
CORRECT ANSWER: C. 20%
,3|Page
EXPERT RATIONALE: Dampwood termites infest wood that is constantly damp, often in
contact with soil or a water source.
QUESTION 5
Formosan termites are particularly aggressive because they:
A. Do not require moisture at all
B. Build carton nests that allow aerial colonies away from soil
C. Only attack hardwoods
D. Produce no swarmers
CORRECT ANSWER: B. Build carton nests that allow aerial colonies away from soil
EXPERT RATIONALE: The carton nest retains moisture, enabling large colonies to survive
above ground without soil contact.
QUESTION 6
Which caste in a subterranean termite colony is responsible for foraging and feeding the
other castes?
A. Swarmers
B. Soldiers
C. Workers
D. Supplementary reproductives
CORRECT ANSWER: C. Workers
EXPERT RATIONALE: Worker termites are the sterile caste that collects food, constructs
tubes, and feeds the queen, soldiers, and young.
QUESTION 7
The soldier caste of a termite colony can be identified by its:
A. Long membranous wings
, 4|Page
B. Large mandibles and elongated head
C. Soft, unpigmented body and blindness
D. Pair of cerci
CORRECT ANSWER: B. Large mandibles and elongated head
EXPERT RATIONALE: Soldiers have enlarged, heavily sclerotized heads and mandibles for
colony defense.
QUESTION 8
Which termite species is most likely to be found in sound, dry wood with no ground
contact?
A. Subterranean termite
B. Dampwood termite
C. Drywood termite
D. Formosan termite
CORRECT ANSWER: C. Drywood termite
EXPERT RATIONALE: Drywood termites live entirely inside dry wood above ground and
do not need soil moisture.
QUESTION 9
Termite swarmers found indoors during early spring in California are often a sign of:
A. An ant infestation
B. A subterranean termite colony under the slab
C. An active drywood termite colony inside the structure
D. A dampwood termite nest in the attic
CORRECT ANSWER: C. An active drywood termite colony inside the structure
