ADAI Pest Control License Categories Explained (Alabama)
This page is a plain-English reference to the Alabama Department
of Agriculture and Industries (ADAI) pest control license categories. It
is the detail companion to the shorter ADAI
licensing overview. Use this page to verify which category a
prospective service provider must hold for the specific work you need.
Governing law & agency
The Alabama Department of Agriculture and Industries, Pesticide
Management Section (1445 Federal Drive, Montgomery, AL 36107; (334)
240-7240) administers all pest-control licensing in Alabama. The
statutory basis is Chapter 28, Title 2, Code of Alabama 1975 (the
Alabama Pesticide Act / Pest Control Industry Act). The regulatory
basis is Chapter 80-1-13 of the Alabama Administrative Code.
Two-tier licensing model
- Individual certification — the human
applicator must be certified as a Private Applicator, Commercial
Applicator, or Custom Applicator, in one or more categories. - Business license — the company must hold a
Structural Professional Services Permit (for HPC / WDC / FC work) or
a Horticultural Professional Services Permit (for OTPS / SLP work).
Structural pest control categories (the relevant set)
| Code | Category | Required for |

| HPB | Household Pest Control — Branch Supervisor | Supervising branch offices. |

Recertification

- Up to 10 of the 30 may come from approved Distance Learning
courses (not repeatable in cycle). - Renewal deadline: 28th of original issue month.
Insurance & recordkeeping
General liability insurance is required. Pesticide application
records must be maintained. All applications must be consistent with
product label / labeling per federal FIFRA and state law.
How this matters for the caller
When the dispatched licensed operator quotes work, the category
held determines what they may legally perform. If the work is a
termite letter (NPMA-33 / WIR), the inspector must hold WDC. If the
work is a whole-structure fumigation tent, the technician must hold
FC. For routine pest service (cockroach, mosquito, ant, bed bug),
HPC is the operative category.

Frequently asked questions
Are the technicians ADAI-licensed?
Yes. Every operator the call routes to is certified by the Alabama Department of Agriculture and Industries (ADAI) under HPC (Household Pest Control), WDC (Wood Destroying Organisms — required for termite letters / NPMA-33), or FC (Fumigation Pest Control). ADAI licensing is administered under Chapter 28, Title 2, Code of Alabama 1975 and Chapter 80-1-13 of the Alabama Administrative Code.
What’s the typical response time?
Routine dispatch: under 60 seconds on the call. On-site arrival: 2–4 hours during business hours (7am–9pm CT, 7 days) for most Mobile County and Baldwin County service areas. Emergency calls are routed to operators on 24/7 on-call rotation.
Do you cover my area in Mobile or Baldwin County?
The network covers all of Mobile County and Baldwin County, including Mobile, Daphne, Fairhope, Spanish Fort, Foley, Gulf Shores, Orange Beach, Bay Minette, Saraland, Tillman’s Corner, Theodore, and surrounding zip codes. See the full service area list.
What does pest control cost?
Pricing is set by the dispatched licensed operator, not by Mobile Alabama Exterminators. Published industry ranges: general pest service $90–$280/month, termite treatment $1,200–$2,500+, WDO inspection $100–$199, bed bug heat $1,500–$4,500+. See termite cost and bed bug cost guides.

Alabama is one of the strictest states in the country on structural pest control regulation. The ADAI Structural Pest Control Section regulates four primary applicator categories — WDC (Wood Destroying Organisms Certified Operator), WDS (WDO Supervisor), FC (Fumigation Pest Control Certified Operator), and GPC (General Pest Control) — each with separate testing, continuing education, and annual renewal.
