Authorized service categories (2) under this license
General Pest Control (Category P)
Category P authorizes the company to perform general structural pest control services. This is the most common license category and covers the identification, treatment, and prevention of common household and commercial pests.
What this license covers:
- Cockroaches, ants, spiders, silverfish, and crickets
- Bed bugs, fleas, ticks, and mosquitoes
- Wasps, hornets, and other stinging insects
- Scorpions, centipedes, and occasional invaders
- Interior and exterior perimeter treatments
- Preventive pest management programs
Why it matters: Category P is the foundation license for most pest control companies. It ensures the company has trained technicians who understand pest biology, proper pesticide application, and safety protocols for treating homes and businesses.
Termite Treatment (Category T)
Category T authorizes the company to inspect for, treat, and prevent termite infestations. This is a specialized license requiring additional training in termite biology, soil treatment, and structural assessment.
What this license covers:
- Subterranean termite treatment (liquid barriers and bait systems)
- Drywood termite treatment (localized and whole-structure)
- Formosan termite identification and treatment
- Pre-construction termite prevention for new buildings
- Termite inspections and WDI (Wood-Destroying Insect) reports
