LOUISIANA STRUCTURAL PEST CONTROL STUDY GUIDE WITH 350
QUESTIONS AND CORRECT RATIONALES
This study resource is specifically tailored for individuals
pursuing the Louisiana Category 1 Structural Pest Control
License. It focuses on the technical, legal, and biological
knowledge required by the Louisiana Department of
Agriculture and Forestry (LDAF) to effectively manage and
treat wood-destroying insects.
1.What is the most important factor in the successful control of German
Cockroaches?
Answer: Sanitation and food removal.
Rationale: German cockroaches have a high reproductive rate; without removing
their food and water sources, chemical treatments will only provide temporary
relief.
2. Which law gives the LDAF the power to inspect a pest control company’s
records?
Answer: The Louisiana Structural Pest Control Act.
Rationale: This state law mandates that all licensed businesses must keep
accurate records and make them available to state inspectors upon request.
3. What is the common name for the "pupal" stage of a flea?
Answer: The Cocoon.
Rationale: The flea larva spins a silk-like cocoon that is sticky and collects dust,
making it nearly invisible and highly resistant to many liquid insecticides.
4. How does a "Contact" pesticide kill a pest?
, Answer: By being absorbed through the pest’s body wall (cuticle).
Rationale: Unlike stomach poisons that must be eaten, contact poisons kill the
insect simply by it walking across a treated surface.
5. Which rodent is most likely to live in a "burrow" in the ground outside a
building?
Answer: Norway Rat.
Rationale: Norway rats are "ground dwellers" and prefer nesting in soil tunnels
near foundations, unlike Roof rats which prefer high places.
6. What is "Pressure Rinshing"?
Answer: Using a special nozzle to wash the inside of a pesticide container.
Rationale: This is a faster alternative to triple-rinsing that uses high pressure to
ensure no chemical residue remains in the jug.
7. Which ant species is considered "Tramp" species because they move
frequently?
Answer: Pharaoh Ants.
Rationale: Pharaoh ants are notorious for "budding" (splitting the colony) if they
sense stress, such as the application of a repellent spray.
8. What does a "Surfactant" do when added to a spray tank?
Answer: It reduces the surface tension of the water.
Rationale: This allows the pesticide droplets to spread out more evenly and
"stick" better to waxy surfaces like leaves or insect bodies.
9. What is the "Abdomen" of an insect?
Answer: The rear body segment.
Rationale: The abdomen contains the insect's digestive system, reproductive
organs, and the spiracles used for breathing.
10. Why is it dangerous to mix Chlorine Bleach with Ammonia-based cleaners?
Answer: It creates toxic chloramine gas.
Rationale: In pest control sanitation, mixing incompatible cleaning chemicals can
lead to fatal respiratory injuries.
11. Which fly is often found breeding in the "schmutz" or film inside floor drains?
Answer: Drain Fly (Moth Fly).
Rationale: Their larvae feed on the gelatinous organic film that builds up in poorly
maintained plumbing.
12. What is the "Pre-Harvest Interval" (PHI)?
Answer: The minimum time between the last application and harvesting a crop.
Rationale: This ensures that pesticide residues have broken down to safe levels
before the food is consumed.
13. Which pest is known to cause "Mechanical Transmission" of disease?
Answer: House Fly.
Rationale: Flies carry pathogens on their feet and mouthparts from waste matter
directly to human food without being infected themselves.
, 14. What is "Incompatibility" in a spray tank?
Answer: When two or more pesticides cannot be mixed safely or effectively.
Rationale: Some chemicals may clump together or lose their killing power if
mixed in the same tank.
15. What is the primary reason for "Wood Decay Fungi" to grow in a crawlspace?
Answer: Excessive moisture (over 20% moisture content).
Rationale: Fungi require water to survive; reducing humidity and fixing leaks is
the only permanent way to stop wood rot.
16. Which term describes the "instinct" of a cockroach to stay in contact with a
surface?
Answer: Thigmotactic.
Rationale: Cockroaches prefer tight spaces where their back and belly touch
surfaces simultaneously, which is why crack and crevice treatments work so well.
17. What is "Pesticide Persistence"?
Answer: How long a pesticide remains active in the environment.
Rationale: Persistent pesticides are good for long-term termite control but can be
a liability if they leach into soil or water.
18. What should you do if your spray hose bursts and spills pesticide on a
customer's lawn?
Answer: Contain the spill, soak it up with absorbent material, and notify your
supervisor.
Rationale: Immediate containment prevents the chemical from spreading into
sewers or deeper into the soil.
19. Which pest has a "flat" body that allows it to hide in the seams of mattresses?
Answer: Bed Bug.
Rationale: Their physical shape is an adaptation for hiding in very narrow cracks
near their human hosts.
20. What is the "Statement of Practical Treatment" on a label?
Answer: The First Aid section.
Rationale: This section tells you exactly what to do if the product is swallowed,
inhaled, or touched.
21. What is "Point Source" contamination?
Answer: Pollution that comes from a specific, identifiable location.
Rationale: A spill at a mixing site is a point source, whereas general runoff from a
field is "non-point source."
22. Which beetle is a "secondary" pest of grain, meaning it eats grain already
damaged by other pests?
Answer: Confused Flour Beetle.
Rationale: These beetles cannot break into whole, undamaged kernels and rely
on grain dust or pre-damaged flour.
23. What is the minimum PPE required for most Category 1 applications?
, Answer: Long-sleeved shirt, long pants, shoes, and socks.
Rationale: These are the standard "base" requirements to prevent skin exposure,
though the label may require more.
24. What is a "Desiccant" dust?
Answer: A dust that kills insects by drying them out.
Rationale: Products like Diatomaceous Earth or Silica Gel strip the waxy coating
off the insect's body, causing them to lose water and die.
25. Which ant is famous for having "multiple nodes" (two bumps) on its waist?
Answer: Pavement Ant.
Rationale: Identifying the number of nodes is the first step in the "Key" used by
entomologists to identify ant species.
26. What is "Emulsifiable Concentrate" (EC)?
Answer: A liquid active ingredient dissolved in an oil-based solvent.
Rationale: When mixed with water, it turns milky white and requires little
agitation.
27. What is the purpose of "Space Spraying" or "Fogging"?
Answer: To kill flying insects or pests currently out in the open.
Rationale: Fogging provides no residual control; it only kills the pests that are
touched by the mist at that moment.
28. What is "IPM Monitoring"?
Answer: The regular checking of traps and sightings to track pest levels.
Rationale: Monitoring tells the technician if the population is growing or shrinking
and if treatment is actually necessary.
29. Which rodent is the best "jumper," able to leap 36 inches vertically?
Answer: Norway Rat.
Rationale: Their physical strength and agility allow them to bypass many physical
barriers.
30. What is "Solubility"?
Answer: The ability of a pesticide to dissolve in a liquid (usually water).
Rationale: Highly soluble pesticides are more likely to leach into groundwater.
31. What are "Spiracles"?
Answer: Breathing holes along the side of an insect's body.
Rationale: Many oils and soaps kill insects by clogging these holes, causing the
insect to suffocate.
32. What is "Synergist"?
Answer: A chemical that makes the pesticide more effective but doesn't kill on its own.
Rationale: Piperonyl Butoxide (PBO) is the most common synergist used to
"knock down" cockroaches faster.
33. Which moth is identified by the "coppery" color on the outer half of its wings?
Answer: Indian Meal Moth.
