TREATMENT EXAM PREP 2026/2027 |
VERIFIED QUESTIONS, ANSWERS &
RATIONALES
• This document is a comprehensive 200-question exam prep resource for the
Kentucky Category 12 Wood Treatment Pesticide Applicator Certification
(2026/2027), featuring verified questions, bolded correct answers, and
detailed EXPERT RATIONALE to reinforce understanding.
• To maximize results, read each question carefully, attempt an answer
before checking the correct option, then study the EXPERT RATIONALE —
focus extra time on any topic where you answer incorrectly.
1. Which of the following is the most economically destructive wood-
destroying insect in the United States?
A. Carpenter ant
B. Carpenter bee
C. Powderpost beetle
D. Subterranean termite ✓
E. Old house borer
Correct Answer: D — Subterranean termite
EXPERT RATIONALE: Subterranean termites cause billions of dollars in structural
damage annually in the United States, making them the most economically significant
wood-destroying insect. They live in underground colonies and access wood through soil
contact or mud tubes.
2. What is the primary purpose of mud tubes constructed by subterranean
termites?
A. To store food for the colony
B. To house the queen
,C. To lay eggs safely
D. To protect workers from desiccation and predators while foraging ✓
E. To mark territory from other colonies
Correct Answer: D — To protect workers from desiccation and predators while
foraging
EXPERT RATIONALE: Subterranean termites require high moisture and are vulnerable to
desiccation. Mud tubes (also called shelter tubes) are constructed from soil, wood
particles, and saliva to maintain humidity and protect workers traveling between the soil
nest and wood food sources.
3. Which termite caste is solely responsible for reproduction within a
subterranean termite colony?
A. Workers
B. Soldiers
C. Nymphs
D. Reproductives (alates and queen) ✓
E. Pseudergates
Correct Answer: D — Reproductives (alates and queen)
EXPERT RATIONALE: The reproductive caste includes the primary queen and king, as
well as supplementary reproductives and winged alates (swarmers). Workers and
soldiers are sterile and perform colony maintenance and defense respectively.
4. Formosan subterranean termites (Coptotermes formosanus) differ from
Eastern subterranean termites primarily in that they:
A. Build no mud tubes
B. Only infest dead trees, not structures
,C. Form much larger colonies and can cause damage more rapidly ✓
D. Are found only in dry climates
E. Do not swarm
Correct Answer: C — Form much larger colonies and can cause damage more
rapidly
EXPERT RATIONALE: Formosan subterranean termite colonies can contain millions of
individuals compared to hundreds of thousands for Eastern subterranean termites. This
larger colony size enables them to cause structural damage significantly faster and
makes them particularly destructive.
5. Which of the following is a key distinguishing characteristic of drywood
termites compared to subterranean termites?
A. Drywood termites require soil contact
B. Drywood termites build extensive mud tubes
C. Drywood termites do not require contact with soil or a moisture source ✓
D. Drywood termites are found only in Kentucky
E. Drywood termites are smaller than subterranean termites
Correct Answer: C — Drywood termites do not require contact with soil or a
moisture source
EXPERT RATIONALE: Drywood termites can live entirely within dry wood and obtain all
necessary moisture from the wood itself and metabolic processes. This independence
from soil makes them uniquely difficult to control with conventional soil barrier
treatments.
6. The presence of frass (fecal pellets) with six flattened sides is a
characteristic sign of infestation by:
A. Subterranean termites
, B. Carpenter ants
C. Drywood termites ✓
D. Powderpost beetles
E. Carpenter bees
Correct Answer: C — Drywood termites
EXPERT RATIONALE: Drywood termites produce hard, six-sided fecal pellets called frass
that they push out of kick-out holes in infested wood. This distinctive frass is one of the
most reliable diagnostic signs of a drywood termite infestation.
7. What does the term "swarmers" or "alates" refer to in termite biology?
A. Aggressive soldier termites
B. Termites that attack predators
C. Winged reproductive termites that leave the colony to establish new ones
✓
D. Worker termites that forage long distances
E. Immature termites in early developmental stages
Correct Answer: C — Winged reproductive termites that leave the colony to
establish new ones
EXPERT RATIONALE: Alates (swarmers) are winged reproductives that disperse from the
parent colony in large swarms, typically in spring. After landing, they shed their wings
and attempt to pair and establish new colonies. Swarms are often the first visible sign of
a termite infestation.
8. How can you distinguish termite swarmers from ant swarmers?
A. Termite swarmers are always larger
