Authorized service categories (4) under this license
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 — officially including nuisance animals such as rats, mice, skunks, raccoons, and opossums (4 TAC §7.124(1)).
What this license covers:
- Cockroaches, ants, spiders, silverfish, and crickets
- Bed bugs, fleas, ticks, and mosquitoes
- Rats, mice, and rodent control
- Nuisance animals: skunks, raccoons, opossums
- Wasps, hornets, and other stinging insects
- Interior and exterior perimeter treatments
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 Control (Category T)
Category T authorizes the company to inspect for, treat, and prevent termite and other wood-destroying insect 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
- Annual monitoring and warranty programs
Why it matters: Termite treatment requires specialized knowledge of soil chemistry, building construction, and treatment techniques. An incorrect application can fail to protect the structure or cause environmental damage. The T category ensures the company meets TDA standards for termite work.
Commodity Fumigation (Category C)
Category C authorizes fumigation of processed commodities, raw agricultural commodities, and structures normally used to contain them — grain bins, silos, warehouses, and food-storage facilities. It excludes fumigation of agricultural equipment and on-farm commodities.
What this license covers:
- Grain bin and silo fumigation
- Warehouse and food-storage facility fumigation
- Stored-product pest control (weevils, grain beetles, moths)
- Mill and feedlot commodity treatment
- Shipping container and railcar fumigation
- Fumigant monitoring and clearance documentation
Why it matters: Commodity fumigation is a distinct credential from Structural Fumigation (S) — one does not authorize the other. The C category ensures the applicator is trained and certified for commodity and storage-structure fumigation work.
Structural Fumigation (Category S)
Category S authorizes whole-structure fumigation using gaseous pesticides. This is the most restrictive license category due to the hazardous nature of fumigants and the complexity of the process.
What this license covers:
- Whole-structure tenting and fumigation
- Fumigant gas monitoring and clearance testing
- Structure sealing and preparation
- Post-fumigation aeration and safety verification
- Documentation and record keeping for fumigant use
- TDA pre-treatment notification compliance
Why it matters: Fumigation involves lethal gases that require specialized training, equipment, and strict safety protocols. Incorrect procedures can endanger lives. The S category requires the highest level of training and oversight, including specific fumigant certifications. Fumigation of grain bins or commodities requires the separate C category.

Can I do pest control myself instead of hiring a professional?
DIY methods can help with minor issues like occasional ants or spiders. However, infestations of termites, bed bugs, rodents, or recurring roaches typically require professional treatment. Licensed technicians have access to commercial-grade products, specialized equipment, and the training to apply treatments safely and effectively.
What does it mean when a pest control license is inactive?
An inactive license means the company has not renewed their TPCL with the Texas Department of Agriculture. This could be due to business closure, failure to meet insurance requirements, or voluntary non-renewal. Companies with inactive licenses cannot legally perform pest control services in Texas.
What pest control regulations does Texas have?
Texas pest control is regulated by the Texas Department of Agriculture (TDA) under the Texas Structural Pest Control Act. All pest control businesses must hold a TPCL license, employ a certified applicator, maintain insurance, and follow specific rules for pesticide application, record keeping, and consumer protection.
What pesticides do Texas pest control companies use?
Licensed Texas companies use EPA-registered products approved for residential and commercial use. Common categories include pyrethroids (synthetic insecticides for general pest barriers), fipronil (effective against ants and termites), neonicotinoids (for various insects), and growth regulators (which disrupt pest reproduction). Your technician should identify specific products used.
What pests does general pest control cover?
General pest control (Category P) covers common household pests including cockroaches, ants, spiders, silverfish, earwigs, crickets, centipedes, and occasional invaders. Some companies include mosquito and flea treatments in their general service, while others offer these as add-ons.
