Which office issues the Virginia Category 7-C (Fumigation) certification?
- The VDACS Office of Pesticide Services (OPS)
- The Virginia Department of Health
- Virginia Tech
- The U.S. Environmental Protection Agency
- The Virginia Department of Motor Vehicles
Show answer
Virginia's Category 7-C (Fumigation) certification is issued by the Office of Pesticide Services (OPS) within the Virginia Department of Agriculture and Consumer Services (VDACS), under the Virginia Pesticide Control Act and 2VAC5-685. Virginia Tech publishes the training manuals and the DMV hosts some exams, but neither issues the credential, and the Department of Health and EPA have other roles. VDACS-OPS is the certifying authority for Virginia fumigators.🔗 Source
Virginia's Category 7-C (Fumigation, non-agricultural) is for:
- General household pest control without fumigants
- Using fumigant pesticides to control pests in structures and items other than soils and raw agricultural commodities
- Wood-destroying pest control without fumigants
- Soil fumigation of crops
- Aquatic weed control
Show answer
Virginia's Category 7-C, Fumigation (non-agricultural), is for using fumigant pesticides to control pests in structures and items other than soils and raw agricultural commodities. General pest control (7-A) and wood-destroying pest control (7-B) specifically exclude fumigants, soil/crop fumigation is agricultural, and aquatic work is a different category. Holding 7-C authorizes non-agricultural fumigation in Virginia.🔗 Source
To certify in Virginia Category 7-C, a Commercial Applicator must pass:
- The 7-A exam only
- No exam, with experience only
- The Core examination plus the 7-C category examination
- A federal EPA exam only
- The 7-B exam only
Show answer
Virginia requires a Commercial Applicator to pass the Core examination plus at least one category examination - here Category 7-C - to be certified. Passing only the 7-A or 7-B exam, no exam, or a federal-only exam do not certify a person for fumigation. Each category is earned by its own exam on top of the Core. This ensures a 7-C applicator has demonstrated fumigation-specific knowledge.🔗 Source
What is the Virginia Commercial Applicator certification application fee, and how often is the certificate renewed?
- $300, renewed every five years
- It is free and never expires
- $1,000, renewed monthly
- $25 (government employees exempt), renewed biennially by June 30
- $25, but it never needs renewal
Show answer
Virginia charges a $25 application fee for Commercial Applicator certification (government employees are exempt) and the certificate is renewed biennially by June 30 of the year on the certificate, with biennial recertification by approved courses or re-testing. It is not $300/five-year, free/permanent, or $1,000/monthly, and it does require renewal. Knowing the modest fee and the biennial cycle helps a Virginia fumigator stay current.🔗 Source
A Virginia business performing fumigation for hire must:
- Do nothing beyond hiring staff
- Hold only a federal EPA number
- Register only its vehicles
- Obtain only a county permit
- Hold a Virginia Pesticide Business License (separate for each location) and employ a certified Commercial Applicator
Show answer
Virginia requires any business that applies or recommends pesticides commercially, including fumigation, to hold a Virginia Pesticide Business License - a separate license for each business location - and to employ a certified Commercial Applicator responsible for the safe application of pesticides. Hiring staff, a federal number, vehicle registration, or a county permit do not meet the requirement. The business-license-plus-certified-applicator structure is the business requirement for Virginia fumigation firms.🔗 Source
Which gas is the primary fumigant used in Virginia non-agricultural (structural) fumigation?
- Sulfuryl fluoride, an odorless and colorless gas
- Carbon dioxide
- Household ammonia
- Propane
- Steam
Show answer
University fumigation references identify sulfuryl fluoride as the primary structural fumigant; it is odorless, colorless, and non-flammable, and penetrates wood to reach hidden pests. Carbon dioxide, ammonia, propane, and steam are not the structural fumigant. In Virginia, fumigation is used for drywood termites, wood-boring beetles, bed bugs, and other pests where whole-structure treatment is appropriate, while the dominant subterranean termites are treated in the soil. Recognizing sulfuryl fluoride as the fumigant is foundational for a 7-C applicant.🔗 Source
What is the purpose of the chloropicrin warning agent in a sulfuryl fluoride fumigation?
- To give the gas a pleasant smell
- Sulfuryl fluoride is odorless and colorless, so chloropicrin's eye and respiratory irritation warns people and deters intruders
- To make the treatment faster
- To avoid sealing the structure
- To add moisture to the wood
Show answer
University fumigation references explain that chloropicrin is introduced as a warning agent because sulfuryl fluoride cannot be smelled or seen; its strong irritation of the eyes and airways at low concentrations warns anyone present that gas is in use and deters intruders from entering the sealed structure. It is not for pleasant smell, speed, skipping the seal, or adding moisture. The chloropicrin warning step is a core fumigation safety practice in Virginia.🔗 Source
Why is a monitored fumigation preferred?
- It removes the need to seal the structure
- It lets occupants remain inside
- It confirms the gas reaches and holds a lethal concentration, giving the highest treatment success
- It provides permanent protection
- It eliminates the warning agent
Show answer
University fumigation references note that a monitored fumigation, using gas-monitoring lines inside the structure, has the highest rate of treatment success because it confirms the gas reaches and maintains a lethal concentration; nonmonitored fumigations may not develop enough concentration and can fail. Monitoring does not remove the need to seal, let occupants stay, provide permanent protection, or eliminate the warning agent. Choosing monitored fumigation improves reliability for a Virginia fumigator.🔗 Source
