GA Dept of Agriculture

The Georgia Wood-Destroying Organism (WDO) credential is Category 30 under the Georgia Department of Agriculture's Structural Pest Control program. To become a certified operator, candidates need roughly two years of verifiable structural pest control experience (or a related degree plus about one year) and must pass a core (general standards) examination plus the WDO category examination, each with at least 70%; the exam fee is $45 per category. WDO operators control subterranean, drywood, and Formosan termites, powderpost and wood-boring beetles, and wood-decaying fungi by means other than fumigation, and they issue the Official Georgia Wood Infestation Inspection Report (WIIR), which carries a 90-day apparent-freedom guarantee. Content spans WDO biology and identification, liquid and bait control methods and Georgia treatment standards, the WIIR, Georgia structural pest law, and pesticide safety. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1In 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?
A.Category 21 (General Pest Control)
B.Category 30 (Wood-Destroying Organism Control)
C.Category 41 (Fumigation)
D.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.
2Which agency administers the Certified Operator examination and licensing for Wood-Destroying Organism control in Georgia?
A.U.S. Environmental Protection Agency (EPA)
B.Georgia Department of Agriculture / Structural Pest Control Commission
C.Georgia Department of Natural Resources
D.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.
3Which subterranean termite caste is responsible for the wood damage that makes termites economically important?
A.Soldiers
B.Workers
C.Alates (swarmers)
D.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.
4A homeowner reports a swarm of winged insects indoors in spring. Which feature most reliably distinguishes a termite alate from a winged ant?
A.Termites have a pinched (constricted) waist; ants do not
B.Termites have two pairs of wings that are equal in length; ants have unequal wing pairs
C.Termites have elbowed antennae; ants have straight antennae
D.Termites are always larger than winged ants
Explanation: A termite alate has four wings of roughly equal length, straight bead-like antennae, and a broad waist. A winged ant has a pinched waist, elbowed antennae, and forewings longer than hindwings. The equal-length wings are a key diagnostic for termites.
5The most common and economically important subterranean termite genus in Georgia structures belongs to which genus?
A.Cryptotermes
B.Reticulitermes
C.Kalotermes
D.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.
6Why do subterranean termites build mud (shelter) tubes across foundation walls and other exposed surfaces?
A.To attract mates during swarming
B.To maintain moisture and protect themselves from light, dry air, and predators while traveling
C.To store cellulose food for winter
D.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.
7An 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?
A.Subterranean termites
B.Lyctid (true) powderpost beetles
C.Carpenter ants
D.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.
8Which family of powderpost beetles typically infests hardwood sapwood and is identified by frass that feels like fine talcum powder?
A.Anobiidae
B.Lyctidae
C.Bostrichidae
D.Cerambycidae
Explanation: Lyctid (true) powderpost beetles in the family Lyctidae attack the sapwood of hardwoods such as oak, ash, and hickory and produce smooth, flour-like frass that feels like talc. Anobiid frass is gritty; cerambycids are the larger round-headed/longhorn borers.
9Anobiid powderpost beetle infestations most often originate in which part of a Georgia structure?
A.Sun-exposed exterior siding
B.Damp, poorly ventilated crawlspaces and substructures
C.Painted interior trim in heated living areas
D.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.
10Hard, six-sided (hexagonal) fecal pellets that resemble tiny seeds or coffee grounds and accumulate below kick-out holes are a hallmark of which organism?
A.Subterranean termites
B.Drywood termites
C.Lyctid powderpost beetles
D.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.

About the Georgia WDO Exam

The Georgia Wood-Destroying Organism (WDO) credential is Category 30 under the Georgia Department of Agriculture's structural pest control program. Certified operators control termites, powderpost and wood-boring beetles, and wood-destroying fungi by means other than fumigation, and they issue the Official Georgia Wood Infestation Inspection Report (WIIR). Candidates must pass a core exam and the WDO category exam with at least 70%.

Exam sponsor: Georgia Department of Agriculture (Structural Pest Control Commission). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Georgia WDO: Suggested Study Strategy

1Master termite identification first: termites have equal-length wings, straight antennae, and no waist, while ants have unequal wings, elbowed antennae, and a pinched waist
2Know the WIIR cold: it covers termites, powderpost/wood-boring beetles, and wood-decay fungi (not mold/mildew), is limited to accessible areas, and carries a 90-day apparent-freedom guarantee
3Understand non-repellent termiticides (e.g., fipronil) and the transfer effect, versus repellent pyrethroid barriers and bait IGRs (noviflumuron/hexaflumuron) that kill at the next molt
4Memorize Georgia treatment standards such as the six-inch minimum trench depth and the rule to apply within the labeled minimum-to-maximum concentration
5Review pesticide safety: signal-word order CAUTION < WARNING < DANGER, dermal as the main exposure route, and the spill response of Control, Contain, Clean up
6Complete all 100 practice questions and review every miss with the AI tutor before sitting the exam

Frequently Asked Questions

What is the Georgia WDO (Category 30) license?

Category 30 is the Georgia Department of Agriculture's Wood-Destroying Organism control category. It covers controlling termites, powderpost and wood-boring beetles, and wood-destroying fungi by means other than fumigation, and authorizes issuing the Official Georgia Wood Infestation Inspection Report (WIIR).

What score do I need to pass the Georgia WDO exam?

You need at least 70% to pass. Certified operator candidates must pass both the core (general standards) examination and the Wood-Destroying Organism category examination, each at a minimum of 70%.

How much does the Georgia structural pest control exam cost?

The examination fee is $45 per category. WDO candidates also take the core exam, and separate license fees and continuing-education requirements apply through the Georgia Department of Agriculture.

What experience do I need before taking the WDO exam?

Georgia generally requires about two years of verifiable structural pest control experience, with one year within the last five years, or a related degree such as entomology plus about one year of structural pest control service experience.

What is the Georgia WIIR and what is its 90-day guarantee?

The Official Georgia Wood Infestation Inspection Report (termite letter) is a visual inspection of readily accessible areas for wood-destroying organisms. It includes a 90-day guarantee: if a covered infestation from which apparent freedom was certified is found within 90 days, the issuing company must treat the structure free of charge.
