Authorized service categories (3) 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.
Lawn & Ornamental (Category L)
Category L authorizes the inspection and control of pests and diseases of lawns, ornamental plants, and trees — in parks and around homes, businesses, industrial sites, and streets. It is the outdoor plant-pest category, separate from structural pest control.
What this license covers:
- Fire ant treatment and yard management
- Grub and chinch bug treatment in turf
- Mosquito yard treatments and barrier sprays
- Flea and tick outdoor applications
- Tree and ornamental insect and disease treatment
- Lawn pest prevention programs
Why it matters: Lawn and ornamental pesticide application requires understanding of turf grass species, plant sensitivity, environmental considerations like runoff, and proper timing for effective treatment. The L category ensures the applicator is trained in outdoor-specific pest management. Herbicide weed work is licensed separately under category W.

Are organic or natural pest control options effective?
Organic methods such as diatomaceous earth, essential oil repellents, and boric acid can be effective for certain pests. However, they often work more slowly and may not be sufficient for severe infestations. Many Texas companies offer green or low-toxicity options that balance effectiveness with environmental responsibility.
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.
Are eco-friendly pest control methods effective?
Modern eco-friendly methods including botanical insecticides, essential oil repellents, diatomaceous earth, and biological controls can be effective for many common pests. They work best as part of an IPM program that emphasizes prevention and monitoring. For severe infestations, conventional products may be needed initially before transitioning to green maintenance.
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.
What venomous snakes are found in Texas?
Texas has four types of venomous snakes: rattlesnakes (Western diamondback, timber, and others), copperheads (common in East and Central Texas), cottonmouths/water moccasins (near water sources), and coral snakes (Southeast Texas). If you cannot identify a snake, keep your distance and call a wildlife removal professional.
