RequiredClemson University Department of Pesticid…
South Carolina's Pesticide Control Act puts licensing in Clemson University's hands — the 'Director' is the head of Clemson's Division of Regulatory and Public Service Programs, and license fees stay with Clemson to run the program (S.C. Code §§ 46-13-20, 46-13-230). Structural pest control is regulated by the director under § 46-13-55.
Any business performing Category 7A work (industrial, institutional, structural and health-related pest control) needs a Pest Control Business License ($150) with a Designated Certified Applicator licensed in 7A ($50) in place first — and no one may be DCA for more than one location. Technicians complete Clemson's Verifiable Technician Training ($50) with annual retraining.
Category 7A and 7B (fumigation) applicators must carry at least $100,000 combined-single-limit liability insurance; coverage lapses suspend the license automatically (§ 46-13-60(e)). Everything expires December 31 each year.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing is entirely state-level through Clemson DPR; cities and counties issue no pest control trade license. The local layer is the business license tax, standardized by § 6-1-400 with a May 1 – April 30 license year, owed wherever the company does business — the City of Charleston, Columbia, Greenville, or Myrtle Beach, or unincorporated Charleston, Richland, Greenville, or Horry County.
The local offices section below names the exact permit desk for every South Carolina county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Business and applicator licenses all expire December 31; work or advertising after that date without renewal violates the Pesticide Control Act.
Renewing after January 1 adds 25% of the original fee; not renewing by April 1 means taking the exam again (§ 46-13-80(C)).
ID cards from the pre-2025 Registered Technician program are still accepted, but those technicians may not apply Restricted Use Pesticides.
A practical sequence for a new pest control contractor in South Carolina. Actual agency processing times are noted in the ledger above.
Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Wilfully working without the appropriate commercial applicator license or Pest Control Business License is a misdemeanor.
In addition to license action, the director may assess civil penalties against anyone paid to apply pesticides who violates the act.
An applicator whose financial responsibility lapses is suspended automatically until proof of coverage is provided.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
Every fact in this file was checked against these official sources on October 2026.
Pending verification: DPR exam fees · Whether termite (wood-destroying organism) work requires any credential beyond Category 7A — the categories page lists no separate WDO category · The DPR licensing page describes five-year blocks ending 2019/2024/2029 for private applicators, while the recertification page sets the commercial block at 2024–2028; the commercial figure is used here · Jurisdiction-specific business license rates and any local trade-license overlays in Charleston, Columbia/Richland County, Greenville, and Horry County/Myrtle Beach were not researched for this record — see the local office records
