How to Start a Pest Control Business in South Carolina

Pest control is built on recurring service: quarterly or monthly treatments for homes, restaurants and commercial buildings. Startup costs are modest, but pesticide use is closely regulated. Your state agriculture or pesticide agency decides which certifications and business licenses you need.

South Carolina requirements for this business

  • Anyone opening a business that performs Category 7A (industrial, institutional, structural and health-related) pest control needs a Pesticide Business License from Clemson's Department of Pesticide Regulation. [source]
  • Each business location needs a Designated Certified Applicator who holds a 7A license, is assigned full time to that location, and has a natural-science degree or at least two years of verifiable pest control experience. [source]
  • Applying 7A pesticides to others' property for pay requires a commercial applicator license, earned by passing the SC Core and category exams; the new license fee is $50. [source]
  • The business license fee is $150 and the DCA license fee is $50; business licenses run January 1 to December 31 and renew annually. [source]
  • Technicians use the Verifiable Technician program launched in February 2025: online training with a $50 initial fee and free annual retraining. [source]

Equipment and supplies

  • Backpack and compressed-air sprayers
  • Hand and bulb dusters
  • Bait stations, traps and insect monitors
  • Flashlight, inspection mirror and moisture meter
  • Respirator, gloves, eye protection and other PPE the labels require
  • Spill kit and locking chemical storage in the vehicle

Licenses and registration

  • If you form an LLC or corporation, register it with your state; if you use a business name other than your own, file a trade name (DBA) where your state requires it (in some states that's the county).
  • EPA requires any person who applies or supervises the use of restricted use pesticides (RUPs) to be certified; state, territorial and tribal authorities certify applicators, with EPA oversight, so contact your state's certifying agency. [source]
  • EPA notes that many states require all commercial applicators, not only those using RUPs, to be certified. [source]
  • Many states also license the pest control business itself and set categories for structural, termite, fumigation or lawn work; check your state agriculture or pesticide regulatory agency.
  • Follow every pesticide label exactly — labels set the rules for use, PPE and re-entry.
  • Commercial clients and general contractors often ask for a certificate of insurance, a W-9 and proof of license.
  • Get a free Employer Identification Number (EIN) from the IRS if you will hire employees or form an LLC or corporation. Beware of sites that charge for this. [source]
  • To find your state's business registration office, use the SBA's state-by-state registration lookup. [source]

Insurance to consider

  • General liability with a pest control or pesticide endorsement
  • Commercial auto for service vehicles
  • Workers' compensation once you hire
  • Errors and omissions, often requested for termite inspections
  • Surety bond if your state requires one for business licensing

Get quotes from several carriers or an independent agent; coverage needs depend on your contracts, state and staff.

Financing options

  • SBA 7(a) loans — the SBA's main guaranteed loan program, made through participating lenders. [source]
  • SBA Microloans — smaller loans delivered through nonprofit intermediary lenders. [source]
  • SBA Lender Match — a free tool that connects you with interested SBA lenders. [source]
  • Free counseling from your local SBDC or SCORE chapter can help you build the business plan lenders ask for. [source]
