Authorized service categories (4) under this license

P

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.

T

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.

L

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.

W

Weed Control (Category W)

Category W authorizes the inspection and control of weeds in rights-of-way, around homes, in parks, and in and around structures, business establishments, industrial parks, institutional buildings, streets, and industrial environs. It is the herbicide category — TDA does not issue a wildlife removal license.

What this license covers:

  • Pre-emergent herbicide applications (crabgrass, annual bluegrass)
  • Post-emergent broadleaf weed spot treatments
  • Fence line, driveway, and hardscape vegetation management
  • Commercial and industrial bare-ground programs
  • Rights-of-way weed control
  • Bundled lawn weed and feed programs

Why it matters: Herbicide application requires training in product selection, turf sensitivity, drift management, and environmental protection. The W category ensures the applicator passed the TDA weed control examination. Looking for animal removal? That work is covered by the Pest Control (P) category or is exempt from TDA licensing when done with live traps.

What should I do before a pest control visit?

Before your appointment, clear counters, move furniture slightly away from walls, secure food and pet dishes, cover fish tanks, and ensure the technician can access areas like garages, attics, and crawl spaces. Your provider will give specific preparation instructions based on the treatment type.

Can I report a pest control company in Texas?

Yes. Complaints against licensed pest control companies can be filed with the Texas Department of Agriculture. You can report unlicensed operators, unsafe practices, or unsatisfactory service. The TDA investigates complaints and can take enforcement action including fines and license suspension.

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.

How do I get rid of fleas in my home?

Effective flea elimination requires treating three areas simultaneously: pets (consult your veterinarian), the home interior (professional spray targeting carpet, furniture, and pet resting areas), and the yard (outdoor treatment of shaded areas). A single flea can lay 50 eggs per day, so complete treatment is essential to break the life cycle.
