Question 1Actual Hawaii and Georgia pesticide qualification boundaries

In Georgia's structural pest control licensing scheme, which category covers the control of termites, powderpost beetles, wood-boring beetles, and wood-destroying fungi by means other than fumigation?

  1. Category 21 (General Pest Control)
  2. Category 30 (Wood-Destroying Organism Control) Correct answer.
  3. Category 41 (Fumigation)
  4. Category 24 (Wood-Destroying Organism Inspection only)

Explanation

Georgia designates Wood-Destroying Organism (WDO) Control as Category 30, covering all measures to control termites, powderpost beetles, wood-boring beetles, and wood-destroying fungi in structures and adjacent areas by means other than fumigation. Fumigation is a separate category.

Question 2Actual Hawaii and Georgia pesticide qualification boundaries

Which agency administers the Certified Operator examination and licensing for Wood-Destroying Organism control in Georgia?

  1. U.S. Environmental Protection Agency (EPA)
  2. Georgia Department of Agriculture / Structural Pest Control Commission Correct answer.
  3. Georgia Department of Natural Resources
  4. National Pest Management Association (NPMA)

Explanation

Structural pest control in Georgia, including the WDO category, is administered by the Georgia Department of Agriculture through the Structural Pest Control Commission and Act. The EPA registers pesticides nationally but does not issue Georgia operator licenses.

Question 3Actual Hawaii and Georgia pesticide qualification boundaries

Under Georgia rules, the Official Georgia Wood Infestation Inspection Report (WIIR) reports evidence of which group of organisms?

  1. Only subterranean termites
  2. Subterranean termites, drywood termites, powderpost/wood-boring beetles, and wood-decaying fungi Correct answer.
  3. All household pests including roaches and rodents
  4. Mold and mildew only

Explanation

The WIIR reports visible evidence of wood-destroying organisms: subterranean termites, drywood termites, powderpost and other wood-boring beetles, and wood-decaying fungi. It specifically excludes molds and mildew, which are not wood-destroying organisms.

Question 4Pest identification, monitoring and integrated management

An integrated pest management (IPM) approach to wood-destroying organisms emphasizes:

  1. Maximum pesticide use as the only solution
  2. Combining inspection, moisture/conducive-condition correction, exclusion, and targeted treatment for long-term control Correct answer.
  3. Treating only after the structure collapses
  4. Relying solely on the homeowner to identify pests

Explanation

IPM for WDOs integrates thorough inspection, correction of moisture and conducive conditions, removal of wood-to-soil contact, exclusion, and judicious, targeted chemical treatment. This multi-tactic strategy provides more durable, environmentally responsible control than relying on chemicals alone.

Question 5Label interpretation, exposure and protective boundaries

Before applying any termiticide, the applicator's first and most authoritative source for mixing rate, application method, and required PPE is:

  1. The product's EPA-approved label and labeling Correct answer.
  2. A coworker's past experience
  3. The customer's preference
  4. A general pest control textbook

Explanation

The actual applicable product labeling supplies the permitted use and required safety conditions, alongside relevant current legal requirements. A familiar product name, rate from another job or generic guide is not a substitute. This is a source-of-authority question, not a chemical mixing or application instruction.

Question 6Label interpretation, exposure and protective boundaries

The phrase on a label that tells how the pesticide enters the body and what acute effects it may cause (e.g., 'harmful if absorbed through skin') is found in which section?

  1. Directions for Use
  2. Precautionary Statements / Hazards to Humans and Domestic Animals Correct answer.
  3. Storage and Disposal
  4. Ingredient Statement

Explanation

The Precautionary Statements, specifically Hazards to Humans and Domestic Animals, describe routes of entry and acute hazards and specify required personal protective equipment. The Directions for Use cover where and how to apply, not the human-hazard warnings.

Question 7Label interpretation, exposure and protective boundaries

Which represents the correct order of pesticide toxicity signal words from least to most acutely toxic?

  1. DANGER, WARNING, CAUTION
  2. CAUTION, WARNING, DANGER Correct answer.
  3. WARNING, CAUTION, DANGER
  4. CAUTION, DANGER, WARNING

Explanation

The listed sequence compares the usual acute-hazard signal-word categories, with DANGER above WARNING above CAUTION. It does not compare every chronic or environmental risk, and a product can carry the highest category for severe local injury rather than identical systemic toxicity by every route. Read the actual hazard statements.

Question 8Calibration, formulation and supplied quantity models

A liquid soil termiticide that termites cannot detect and will tunnel through, picking up a lethal dose and transferring it to nestmates, is best described as:

  1. A repellent termiticide
  2. A non-repellent (undetectable) termiticide Correct answer.
  3. A fumigant
  4. An insect growth regulator bait

Explanation

Non-repellent termiticides (such as fipronil or chlorantraniliprole) are undetectable to termites, so they tunnel through treated soil, contact the active ingredient, and can transfer it to nestmates through grooming and contact. Repellent products instead deter termites from entering treated soil.

Question 9Calibration, formulation and supplied quantity models

Which active ingredient is a widely used non-repellent soil termiticide?

  1. Bifenthrin
  2. Fipronil Correct answer.
  3. Permethrin
  4. Cypermethrin

Explanation

Fipronil (e.g., Termidor) is a non-repellent (undetectable) termiticide that termites tunnel through and carry back to the colony. Bifenthrin, permethrin, and cypermethrin are pyrethroids, which act primarily as repellent barrier treatments.

Question 10Calibration, formulation and supplied quantity models

Termite baiting systems such as those using noviflumuron or hexaflumuron eliminate colonies because these active ingredients are:

  1. Fast-acting neurotoxins that kill on contact
  2. Chitin synthesis inhibitors that prevent termites from successfully molting Correct answer.
  3. Repellents that drive termites away from the structure
  4. Fumigant gases released inside the wood

Explanation

The named active ingredients act as chitin synthesis inhibitors and disrupt successful molting under appropriate exposure conditions. Colony control depends on the actual system, feeding, monitoring and environment; the mechanism alone does not guarantee elimination in every structure. Follow actual applicable labeling and competent management rather than a universal bait prescription.

Question 11Drift, runoff, soil movement and sensitive receptors

What are the primary ways pesticides can contaminate groundwater?

  1. Only through direct spills into wells
  2. Through leaching (downward movement through soil), point-source contamination (spills, back-siphoning, improper disposal), and sinkholes or improperly constructed wells Correct answer.
  3. Only through surface water runoff
  4. Groundwater contamination from pesticides cannot occur

Explanation

Pesticides reach groundwater through several pathways: leaching (the active ingredient moves downward through the soil profile with water), point-source contamination (mixing/loading spills near wells, improper container disposal, back-siphoning during tank filling), and preferential flow paths (sinkholes, fractured bedrock, poorly sealed wells). Sandy soils, shallow water tables, and persistent, water-soluble pesticides increase leaching risk.

Question 12Drift, runoff, soil movement and sensitive receptors

What soil characteristics increase the risk of pesticide leaching to groundwater?

  1. High clay content and high organic matter
  2. Sandy or coarse-textured soils with low organic matter, high permeability, and shallow depth to the water table Correct answer.
  3. Only soils in arid regions
  4. Only acidic soils

Explanation

Soils with high leaching risk have: coarse texture (sand, gravel) that allows rapid water movement, low organic matter (less adsorption of pesticides), high permeability, and shallow depth to the water table. Additionally, soils with preferential flow paths (cracks, root channels, worm holes) can rapidly transmit pesticides to groundwater. Clay soils and high organic matter content help bind pesticides and reduce leaching.

Question 13Drift, runoff, soil movement and sensitive receptors

What is "surface water runoff" and how can pesticide applicators reduce it?

  1. Water running off the surface of plant leaves; it cannot be reduced
  2. Water moving across the soil surface carrying dissolved or suspended pesticides to streams, lakes, or wetlands; reduced by maintaining vegetated buffer strips, avoiding application before rain, and reducing erosion Correct answer.
  3. Water that evaporates from the soil surface
  4. Irrigation water flowing off the end of a field

Explanation

Surface water runoff occurs when water flows across the soil surface, carrying dissolved pesticides and pesticide-laden soil particles to surface water bodies. Applicators can reduce runoff by: maintaining vegetated buffer strips along waterways, not applying before predicted heavy rain, incorporating soil-applied pesticides, using reduced tillage to improve infiltration, following label setback requirements from water, and timing applications to avoid wet soil conditions.

Question 14Wood-destroying organisms, inspection evidence and Georgia reports

Which subterranean termite caste is responsible for the wood damage that makes termites economically important?

  1. Soldiers
  2. Workers Correct answer.
  3. Alates (swarmers)
  4. The queen

Explanation

The worker caste forages for cellulose, feeds the other castes, and excavates wood and tunnels; it is therefore responsible for the structural damage. Soldiers defend the colony and reproductives reproduce, but neither feeds on wood to cause damage.

Question 15Wood-destroying organisms, inspection evidence and Georgia reports

A homeowner reports a swarm of winged insects indoors in spring. Which feature most reliably distinguishes a termite alate from a winged ant?

  1. Termites have a pinched (constricted) waist; ants do not
  2. Termites have two pairs of wings that are equal in length; ants have unequal wing pairs Correct answer.
  3. Termites have elbowed antennae; ants have straight antennae
  4. Termites are always larger than winged ants

Explanation

The relative wing-length comparison supports distinguishing the supplied termite alate from a winged ant, together with other features such as antennae and waist. Damaged specimens or incomplete observations can limit identification. A matching feature does not by itself prove the extent or activity of a structural infestation.

Question 16Wood-destroying organisms, inspection evidence and Georgia reports

The most common and economically important subterranean termite genus in Georgia structures belongs to which genus?

  1. Cryptotermes
  2. Reticulitermes Correct answer.
  3. Kalotermes
  4. Zootermopsis

Explanation

Native eastern subterranean termites of the genus Reticulitermes (notably Reticulitermes flavipes) are the most widespread and damaging termites in Georgia. Cryptotermes and Kalotermes are drywood termites; Zootermopsis are dampwood termites of the western U.S.

Question 17Actual Hawaii and Georgia pesticide qualification boundaries

Who is legally authorized to issue the Official Georgia Wood Infestation Inspection Report?

  1. Any licensed home inspector
  2. A real estate agent representing the seller
  3. A company licensed and a certified operator in the Wood-Destroying Organism category Correct answer.
  4. Any registered pest control employee, regardless of category

Explanation

Only a pest control company licensed in the WDO category, working through a certified operator (or properly registered employee under that operator), may issue the Official Georgia WIIR. Home inspectors and real estate agents are not authorized to issue it.

Question 18Actual Hawaii and Georgia pesticide qualification boundaries

When visible evidence of active or previous WDO infestation is found during a Georgia inspection, what must be attached to the WIIR?

  1. A copy of the inspector's license only
  2. A diagram identifying the structure(s) and showing the location of the evidence Correct answer.
  3. A laboratory soil analysis
  4. Photographs of every room

Explanation

Georgia rules require that when visible evidence is found, a diagram identifying the inspected structure(s) and showing the location of the evidence be attached to the WIIR. This graph documents exactly where activity or damage was observed.

Question 19Actual Hawaii and Georgia pesticide qualification boundaries

A Georgia WIIR inspection is limited to what kind of areas?

  1. All areas, including behind finished walls and inside sealed voids
  2. Only readily accessible areas; inaccessible areas not inspected must be disclosed Correct answer.
  3. Only the exterior of the structure
  4. Only areas the buyer specifically requests

Explanation

A WIIR is a visual inspection of readily accessible areas. Inspectors cannot dismantle the structure, so they must note inaccessible or obstructed areas that were not inspected. This protects both the consumer and the inspector by clarifying the scope.

Question 20Actual Hawaii and Georgia pesticide qualification boundaries

On the Official Georgia WIIR, how must the inspector handle areas that are obstructed, finished, or otherwise not accessible for inspection?

  1. Certify them as free of infestation anyway
  2. List or note them as inaccessible areas that were not inspected Correct answer.
  3. Ignore them since they are not the inspector's responsibility
  4. Charge an extra fee to inspect them later without disclosure

Explanation

Because a WIIR is limited to readily accessible areas, the inspector must clearly disclose inaccessible or obstructed areas that were not inspected. Certifying unseen areas as free of infestation would misrepresent the inspection and expose the company to liability.

Question 21Actual Hawaii and Georgia pesticide qualification boundaries

A WIIR is most commonly requested in connection with which transaction?

  1. Annual income tax filing
  2. Real estate sale, refinance, or mortgage (including HUD/VA) closings Correct answer.
  3. Renewal of a vehicle registration
  4. Applying for a business license

Explanation

The WIIR (termite letter) is most often required for real estate sales, refinances, and mortgage closings, including HUD and VA loans, to document the wood-destroying organism status of a property before the transaction completes.

Question 22Actual Hawaii and Georgia pesticide qualification boundaries

To qualify as a Certified Operator in the Georgia WDO category, a candidate must pass which combination of examinations?

  1. Only the WDO category exam
  2. The core (general standards/competency) exam plus the WDO category exam Correct answer.
  3. Only the core exam
  4. A fumigation exam plus the WDO exam

Explanation

Georgia requires Certified Operator candidates to pass the core (general standards) examination and an examination in each category they wish to be licensed in, such as Category 30 WDO. The core covers general pesticide safety, law, and application principles common to all categories.

Question 23Actual Hawaii and Georgia pesticide qualification boundaries

A registered (non-certified) employee performing WDO treatments in Georgia must work:

  1. Completely independently with no oversight
  2. Under the supervision and responsibility of a certified operator licensed in the WDO category Correct answer.
  3. Only after passing the core exam alone
  4. Only on commercial, never residential, properties

Explanation

Registered employees may perform WDO work only under the supervision and responsibility of a certified operator licensed in that category. The certified operator is accountable for the company's pesticide use and for the work performed by registered employees.

Question 24Actual Hawaii and Georgia pesticide qualification boundaries

Under Georgia law, applying a pesticide in a manner inconsistent with its EPA-approved labeling is:

  1. Permitted if results improve
  2. A violation of both federal and Georgia pesticide law Correct answer.
  3. Allowed if the customer signs a waiver
  4. Only a concern for agricultural, not structural, applicators

Explanation

Use inconsistent with labeling violates FIFRA and Georgia's structural pest control law. The label is a legal document; deviating from rates, sites, methods, or safety directions can result in penalties, license action, and liability.

Question 25Actual Hawaii and Georgia pesticide qualification boundaries

Georgia rules require pest control companies to keep records of WDO treatments and inspections primarily so that:

  1. Customers can be charged twice
  2. The company and the Department can verify what product was used, where, when, and at what rate Correct answer.
  3. Records can replace product labels
  4. Inspectors can avoid doing follow-up visits

Explanation

Treatment and inspection records document the product used, target site, date, rate, and applicator, enabling the company and the Georgia Department of Agriculture to verify proper, legal application and to investigate complaints. Accurate recordkeeping is a core regulatory requirement.

Question 26Actual Hawaii and Georgia pesticide qualification boundaries

The Georgia agency body that adopts the rules governing structural pest control practice (including WDO) is the:

  1. Georgia Public Service Commission
  2. Georgia Structural Pest Control Commission Correct answer.
  3. Georgia Real Estate Commission
  4. Georgia Environmental Protection Division

Explanation

The Georgia Structural Pest Control Commission, within the Department of Agriculture, adopts and enforces the rules (Chapter 620 series) governing licensing, treatment standards, and the WIIR for structural pest control, including the WDO category.

Question 27Actual Hawaii and Georgia pesticide qualification boundaries

Which scenario would most likely be an enforceable violation of Georgia structural pest control law?

  1. Diluting a termiticide exactly to the labeled rate
  2. Issuing a WIIR certifying apparent freedom for areas the inspector never accessed, without disclosing them as inaccessible Correct answer.
  3. Reporting all visible evidence accurately on the diagram
  4. Recommending moisture correction to the homeowner

Explanation

Certifying apparent freedom for areas that were not actually inspected, without disclosing them as inaccessible, misrepresents the inspection and violates the rules governing the WIIR. Accurate reporting and disclosure of inaccessible areas are mandatory.

Question 28Actual Hawaii and Georgia pesticide qualification boundaries

If an inspector cannot enter a crawlspace because the access is sealed or too low, the correct WIIR practice is to:

  1. Assume the crawlspace is infested and report it as active
  2. Note on the report that the crawlspace was inaccessible and not inspected Correct answer.
  3. Certify the crawlspace as free of infestation
  4. Skip the report entirely

Explanation

When an area cannot be accessed, the inspector must document it as an inaccessible area not inspected on the WIIR. Neither assuming infestation nor certifying freedom is appropriate, because the area was not actually observed.

Question 29Actual Hawaii and Georgia pesticide qualification boundaries

The WIIR is fundamentally what type of inspection?

  1. A destructive inspection requiring opening walls
  2. A visual inspection of readily accessible areas at a point in time Correct answer.
  3. A guarantee that the structure will never have termites
  4. A structural engineering damage assessment

Explanation

The actual state-defined inspection reports relevant observations in the examined accessible areas at the inspection time, with the required limitations and conditions. It is not an unlimited structural soundness assessment or a promise that concealed infestation cannot exist. Consult current Georgia requirements for actual issuance and guarantee interpretation.

Question 30Label interpretation, exposure and protective boundaries

The most common route of pesticide exposure for a structural applicator handling concentrates and treating crawlspaces is:

  1. Ocular (eyes) only
  2. Dermal (through the skin) Correct answer.
  3. Auditory (through hearing)
  4. Through the fingernails only

Explanation

Dermal (skin) exposure is the most common route for applicators because skin contacts spray, drift, and contaminated equipment throughout the workday. This is why labels emphasize chemical-resistant gloves, long sleeves, and washing exposed skin.

Question 31Label interpretation, exposure and protective boundaries

In this task the actual product label specifies a compatible nitrile glove option. Which listed selection follows the chemical-resistance and label requirement rather than treating every glove material as suitable?

  1. Cotton or leather gloves
  2. Chemical-resistant gloves such as nitrile or as specified on the label Correct answer.
  3. Thin latex examination gloves
  4. No gloves, to maintain dexterity

Explanation

Labels specify chemical-resistant gloves (commonly nitrile or other barrier materials) for handling concentrates. Cotton and leather absorb pesticides and hold them against the skin, increasing exposure rather than protecting against it.

Question 32Label interpretation, exposure and protective boundaries

Why must an applicator avoid letting termiticide contaminate a well or cistern during a soil treatment?

  1. It changes the water color only
  2. It can contaminate drinking water, harming people and violating the label and law Correct answer.
  3. It improves the water taste
  4. Labels encourage treating near wells

Explanation

Termiticide reaching a well or cistern can contaminate drinking water, posing a serious health risk and violating label restrictions and Georgia law. Labels include specific setbacks and prohibitions around wells; applicators must locate and protect these before treating.

Question 33Label interpretation, exposure and protective boundaries

The Safety Data Sheet (SDS) for a termiticide is most useful to an applicator for:

  1. Setting the retail price
  2. Detailed hazard, first-aid, handling, and emergency information about the product Correct answer.
  3. Choosing the company logo
  4. Scheduling customer appointments

Explanation

The SDS provides detailed information on hazards, composition, first aid, firefighting, accidental-release (spill) measures, handling/storage, exposure controls, and toxicology. It complements the label and is essential for emergency and medical response.

Question 34Label interpretation, exposure and protective boundaries

Proper pesticide storage for a structural pest control company requires that products be:

  1. Stored next to food and animal feed
  2. Kept in original labeled containers in a secured, ventilated area away from food, feed, and unauthorized access Correct answer.
  3. Transferred into unlabeled drink bottles for convenience
  4. Stored in direct sunlight to keep them warm

Explanation

Pesticides must remain in their original labeled containers and be stored in a secure, ventilated location away from food, feed, water sources, and children/unauthorized persons. Transferring pesticides into beverage containers is dangerous and illegal.

Question 35Calibration, formulation and supplied quantity models

In a standard liquid soil treatment of a structure, what is the primary objective of the termiticide application?

  1. To attract termites away from the structure
  2. To establish a continuous treated soil zone (barrier) between the soil and the wood Correct answer.
  3. To sterilize the soil so no plants can grow near the foundation
  4. To raise the soil pH to repel termites

Explanation

Conventional liquid soil treatment aims to create a complete, continuous treated zone in the soil along foundations, around piers, and beneath slabs so termites cannot reach the wood without contacting the termiticide. Gaps (untreated spots) are the most common cause of treatment failure.

Question 36Calibration, formulation and supplied quantity models

In a monitoring-and-baiting program, what is the purpose of in-ground bait stations placed around a structure before active bait (toxicant) is installed?

  1. To immediately kill the colony on contact
  2. To intercept and detect foraging termites so active bait can then be added Correct answer.
  3. To repel termites from the soil
  4. To serve as a permanent soil barrier

Explanation

In monitoring-based systems, untreated wood or cellulose monitors first intercept foraging termites. Once activity is confirmed, the active bait matrix is added so foragers feed and distribute the slow-acting toxicant to the colony. Newer systems may install active bait from the start.

Question 37Calibration, formulation and supplied quantity models

What is the most common cause of a liquid soil termiticide treatment failing to stop subterranean termites?

  1. Using the labeled product
  2. Gaps or untreated areas leaving a discontinuity in the treated zone Correct answer.
  3. Treating during the day
  4. Using a non-repellent active ingredient

Explanation

Treatment failures most often result from gaps in the treated zone, untreated areas where termites bypass the termiticide, such as missed plumbing penetrations, expansion joints, or inaccessible spots. A continuous, complete treated zone is essential.

Question 38Calibration, formulation and supplied quantity models

An advantage of a colony-elimination baiting system over a conventional liquid barrier is that baiting:

  1. Always works faster than liquids
  2. Can eliminate the termite colony itself and uses very little active ingredient in the environment Correct answer.
  3. Requires no monitoring
  4. Creates a continuous chemical barrier in the soil

Explanation

An appropriate baiting programme can target colony processes with relatively small quantities of active ingredient in suitable conditions. It does not guarantee colony elimination or establish that every baiting plan is preferable to every other option. Compare actual organism, site, labeling and monitoring evidence before a real management decision.

Question 39Calibration, formulation and supplied quantity models

When calibrating a soil-treatment rig, the applicator must know the application rate in order to:

  1. Set the truck's road speed
  2. Deliver the correct labeled volume/concentration of termiticide per linear or square foot of treated soil Correct answer.
  3. Determine the color of the finished mix
  4. Decide the customer's price only

Explanation

Calibration ensures the rig delivers the correct labeled volume and concentration of finished termiticide per linear foot of trench or per square foot of soil. Without calibration, the applicator may under-treat (failure) or over-treat (illegal, environmental hazard).

Question 40Wood-destroying organisms, inspection evidence and Georgia reports

Why do subterranean termites build mud (shelter) tubes across foundation walls and other exposed surfaces?

  1. To attract mates during swarming
  2. To maintain moisture and protect themselves from light, dry air, and predators while traveling Correct answer.
  3. To store cellulose food for winter
  4. To mark territory against competing colonies

Explanation

Subterranean termites have soft, thin cuticles and quickly desiccate. They construct mud tubes from soil, saliva, and feces to keep humidity high and shield themselves from light, dry air, and predators as they travel between soil and wood.

Question 41Wood-destroying organisms, inspection evidence and Georgia reports

An inspector finds clean, round exit holes about 1/32 to 1/16 inch in diameter in hardwood flooring with a pile of fine, flour-like powder beneath. This is most characteristic of which wood-destroying organism?

  1. Subterranean termites
  2. Lyctid (true) powderpost beetles Correct answer.
  3. Carpenter ants
  4. Drywood termites

Explanation

Lyctid powderpost beetles attack the sapwood of hardwoods and produce small round exit holes with frass that is fine and feels like talcum powder. Subterranean termites leave mud, not clean holes; carpenter ants leave coarse shavings; drywood termites eject six-sided fecal pellets.

Question 42Wood-destroying organisms, inspection evidence and Georgia reports

Anobiid powderpost beetle infestations most often originate in which part of a Georgia structure?

  1. Sun-exposed exterior siding
  2. Damp, poorly ventilated crawlspaces and substructures Correct answer.
  3. Painted interior trim in heated living areas
  4. Roof sheathing in a ventilated attic

Explanation

Anobiid powderpost beetles prefer wood with higher moisture content, so infestations typically begin in moist, poorly ventilated crawlspaces, basements, and substructures. Improving ventilation and reducing moisture is a key control and prevention measure.

Question 43Wood-destroying organisms, inspection evidence and Georgia reports

Hard, six-sided (hexagonal) fecal pellets that resemble tiny seeds or coffee grounds and accumulate below kick-out holes are a hallmark of which organism?

  1. Subterranean termites
  2. Drywood termites Correct answer.
  3. Lyctid powderpost beetles
  4. Wood-decay fungi

Explanation

Drywood termites push their characteristic hard, six-sided fecal pellets out of small kick-out holes, forming small piles below the infested wood. They live entirely in dry wood without soil contact, unlike subterranean termites.

Question 44Wood-destroying organisms, inspection evidence and Georgia reports

Which statement best distinguishes drywood termites from subterranean termites?

  1. Drywood termites require constant contact with soil moisture
  2. Drywood termites live entirely within the wood and do not require soil contact Correct answer.
  3. Drywood termites build mud tubes over foundations
  4. Drywood termites are the most common WDO in Georgia structures

Explanation

Drywood termites obtain moisture from the wood itself and from metabolic water, so they infest dry, sound wood without any soil connection. Subterranean termites must maintain contact with soil moisture and build mud tubes to travel.

Question 45Wood-destroying organisms, inspection evidence and Georgia reports

Brown rot fungus attacking structural lumber typically produces what characteristic appearance in the decayed wood?

  1. A bleached, stringy, white fibrous appearance
  2. Wood that is darkened and breaks into dry, cubical cross-grain pieces Correct answer.
  3. Smooth round exit holes with talc-like powder
  4. Hard six-sided fecal pellets

Explanation

Brown rot fungi consume the cellulose and leave the brown lignin, so decayed wood darkens, shrinks, and cracks into cubical (checkered) pieces that crumble to powder when dry. White rot, by contrast, leaves a bleached, stringy appearance.

Question 46Wood-destroying organisms, inspection evidence and Georgia reports

Wood-decay (rot) fungi generally require wood moisture content above approximately what level to grow and cause decay?

  1. About 5%
  2. About 12%
  3. About 20% Correct answer.
  4. About 50%

Explanation

Decay fungi typically require wood moisture content at or above roughly 20% (near or above the fiber saturation point) to become active. Keeping structural wood below about 20% moisture, by controlling leaks and ventilation, prevents most decay.

Question 47Wood-destroying organisms, inspection evidence and Georgia reports

A soldier subterranean termite is most easily recognized by which feature?

  1. A pair of long, membranous wings
  2. An enlarged, darker head with prominent mandibles Correct answer.
  3. A swollen, egg-laying abdomen
  4. Compound eyes and elbowed antennae

Explanation

Soldiers have an elongated, darker, sclerotized head bearing large mandibles used to defend the colony against ants and other invaders. They cannot feed themselves and depend on workers for nourishment.

Question 48Wood-destroying organisms, inspection evidence and Georgia reports

Carpenter ants differ from termites in that carpenter ants:

  1. Eat the wood they tunnel through for nutrition
  2. Excavate galleries for nesting but do not eat the wood, leaving coarse sawdust-like shavings Correct answer.
  3. Build soil mud tubes across foundations
  4. Produce six-sided fecal pellets

Explanation

Carpenter ants do not digest cellulose; they hollow out galleries for nesting and push out coarse, fibrous wood shavings (often mixed with insect parts). Their smooth, clean galleries and shavings distinguish them from the soil-packed galleries of subterranean termites.

Question 49Wood-destroying organisms, inspection evidence and Georgia reports

Which conducive condition most directly promotes subterranean termite access to a structure and should be noted on a Georgia inspection?

  1. Vinyl siding installed over house wrap
  2. Wood-to-soil (earth-to-wood) contact such as form boards, wood debris, or buried scrap lumber Correct answer.
  3. A properly sloped concrete driveway
  4. An insulated, conditioned attic

Explanation

Wood-to-soil contact gives subterranean termites a direct, hidden path from the ground into structural wood. Form boards left in place, scrap lumber, and wood debris under the structure are classic conducive conditions an inspector must report.

Question 50Wood-destroying organisms, inspection evidence and Georgia reports

A primary safety concern unique to crawlspace soil treatment is that the applicator must:

  1. Avoid drilling any holes
  2. Be aware of the location of heating/AC ducts, water wells, drainage, and sub-slab utilities to prevent contamination Correct answer.
  3. Never wear a respirator in a confined space
  4. Apply at twice the labeled rate to compensate for the enclosed area

Explanation

Before treating, applicators must identify and avoid HVAC ducts, plenums, wells, cisterns, drainage systems, and buried utilities so termiticide does not contaminate water or living-space air. Many labels prohibit treatment that could introduce product into these systems.
