Which agency regulates the Tennessee Structural Fumigation (FUM) license?
- The Tennessee Department of Agriculture (TDA), Pesticide Section
- The Tennessee Department of Health
- The University of Tennessee
- The U.S. Environmental Protection Agency
- The Tennessee Department of Environment and Conservation
Show answer
Tennessee's Structural Fumigation (FUM) license is regulated by the Tennessee Department of Agriculture (TDA) under the Tennessee Application of Pesticides Act (TAPA) and related rules. The University of Tennessee provides study materials and training, while the Department of Health, EPA, and Department of Environment and Conservation have other roles. TDA is the regulator for Tennessee fumigators.🔗 Source
In Tennessee, the Structural Fumigation (FUM) license covers:
- Soil fumigation of agricultural fields
- Control of pests by application of a gas on sites other than soil
- Household pest control by liquid sprays
- Mosquito control in public waters
- Right-of-way weed control
Show answer
Tennessee's Structural Fumigation (FUM) license covers the control of pests by application of a gas on sites other than soil - pesticides that are solid or liquid when handled but turn to gas when dispensed. Soil fumigation of fields is the separate FUS category, household liquid spraying is GRC work, and mosquito and right-of-way work fall under other licenses. A FUM (or WDO) license is also required to make a custom application for wood-destroying beetles. Holding FUM authorizes structural fumigation in Tennessee.🔗 Source
Before obtaining a Tennessee FUM license, an applicant must first be commercially certified in which category, and pass which exam?
- Category C01, then pass a free exam
- No certification or exam is required
- Category C07, then pass the $150 License exam (questions plus specimen ID) at 70%
- Only a federal EPA exam
- Category C05, then pass a $25 exam
Show answer
Tennessee requires a FUM license applicant to first be commercially certified in Category C07 (Industrial, Institutional, Structural and Health-Related Pest Control) and then pass the operational License examination - which costs $150 and includes both written questions and specimen identification - with a score of 70%. C01 (agricultural) and C05 (aquatic) are not the prerequisite for FUM, certification and an exam are required, and a federal-only exam does not substitute. The certification-then-license structure governs Tennessee fumigation licensing.🔗 Source
Under Tennessee's charter rules, a new company holding a FUM (or WDO, GRC, or BDC) licensee must post:
- No bond at all
- Only a $20 fee
- Only automobile insurance
- An additional $50,000 bond, on top of the charter's base $10,000 bond and liability insurance
- A $5 million cash deposit
Show answer
Tennessee requires a new company holding a WDO, GRC, FUM, or BDC licensee to post an additional $50,000 bond, on top of the base charter requirements of a $10,000 surety bond and liability insurance of $250,000 per incident and $500,000 aggregate. No bond, a $20 fee, auto-only insurance, or a multimillion-dollar cash deposit do not match the rule. These financial-responsibility requirements protect consumers who hire a fumigation firm. Knowing the FUM bonding requirement is part of operating a compliant Tennessee fumigation business.🔗 Source
To offer fumigation services for compensation in Tennessee, a firm must hold:
- Only a federal EPA number
- No permit of any kind
- Only a county business license
- Only a University of Tennessee certificate
- A pest control charter (required for each business location), with at least one FUM licensee listed
Show answer
Tennessee requires a firm offering custom (for-hire) pesticide application, including fumigation, to hold a pest control charter for each business location, and the charter must list at least one licensee for each category of service offered - here a FUM licensee. A federal number, no permit, a county license, or a university certificate do not substitute, and operating without a charter is a Class A misdemeanor. The charter-plus-licensee structure is the business requirement for Tennessee fumigation firms.🔗 Source
Which gas is the primary fumigant for Tennessee structural fumigation?
- Sulfuryl fluoride, an odorless and colorless gas
- Carbon dioxide
- Chlorine bleach vapor
- Propane
- Ordinary air
Show answer
University fumigation references identify sulfuryl fluoride as the primary structural fumigant; it is odorless, colorless, and non-flammable, and it penetrates wood to reach hidden pests. Carbon dioxide, bleach vapor, propane, and ordinary air are not the structural fumigant. In Tennessee, fumigation is used for drywood termites, wood-boring beetles, and similar 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.🔗 Source
Structural fumigation is appropriate for which pest, and NOT appropriate for which?
- Appropriate for subterranean termites only
- Appropriate for drywood termites and wood-boring beetles; not for subterranean termites, which live in the soil
- Appropriate for turf weeds
- Appropriate for pond algae
- Appropriate only for surface-visible pests
Show answer
University references explain that whole-structure fumigation is appropriate for pests that live within the structure, such as drywood termites and wood-boring beetles (and bed bugs), but not for subterranean termites, which live in the soil and are controlled with soil treatments or baits. Fumigation is not for turf weeds, pond algae, or only surface-visible pests. Because Tennessee is dominated by the eastern subterranean termite, understanding that fumigation targets drywood (not subterranean) termites prevents misapplication.🔗 Source
Why is a warning agent such as chloropicrin used in fumigation?
- To make the gas smell pleasant
- To speed the treatment
- Because the fumigant is odorless and colorless, the warning agent's eye and respiratory irritation alerts people and deters entry into the sealed structure
- To replace the tarps
- To fertilize the wood
Show answer
University fumigation references explain that, because sulfuryl fluoride is odorless and colorless, a warning agent such as chloropicrin is introduced; its 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, replacing tarps, or fertilizing wood. The warning-agent step is a core fumigation safety practice in Tennessee and elsewhere.🔗 Source
