Authorized service categories (2) under this license

P

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.

T

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
  • 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.

Frequently Asked Questions

Common questions about pest control services in Houston, TX

What questions should I ask before hiring a pest control company?

Key questions include: Are you licensed by the Texas Department of Agriculture? What is your TPCL number? What specific treatment do you recommend and why? What products will you use? Do you offer a guarantee or warranty? Are your technicians certified applicators? What preparation is needed on my part?

What happens if pests come back after treatment?

Most pest control companies offer re-treatment guarantees — if pests return between scheduled visits, they will re-treat at no additional charge. This is standard with ongoing service plans. For one-time treatments, ask about the warranty period. Persistent issues may indicate entry points that need sealing or environmental factors that need addressing.

Should I get multiple quotes before choosing a pest control company?

Yes. Getting 2–3 estimates is recommended. Compare not just price but also the scope of service, products used, guarantees offered, and customer reviews. The cheapest option is not always the best — look for licensed, well-reviewed companies that clearly explain their treatment plan.

What is a certified applicator in Texas pest control?

A certified applicator is an individual who has passed the TDA examination demonstrating knowledge of pest identification, pesticide safety, application techniques, and state regulations. Texas law requires every pest control business to designate a certified applicator who supervises all pest management activities performed by the company.

What are the different pest control license categories in Texas?

The TDA issues licenses with specific category codes: P (General Pest Control), T (Termite Treatment), L (Lawn & Landscape), W (Wildlife Removal), C (Crack & Crevice), S (Structural Fumigation), and D (Waste Disposal). Each category authorizes different types of pest management work.

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 types of termites are found in Texas?

Texas has three main termite types: Eastern subterranean termites (most common, found statewide), Formosan subterranean termites (aggressive species in Southeast Texas and coastal areas), and drywood termites (found in attics and furniture, mainly in South and Coastal Texas). Each requires different treatment approaches.

Are there dangerous spiders in Texas?

Texas has two medically significant spider species: the brown recluse (found statewide, especially in Central Texas) and the black widow (found throughout the state). Brown recluse bites can cause tissue necrosis, while black widow bites can cause muscle pain and systemic symptoms. Most other Texas spiders are harmless.

What pest control challenges are unique to Texas?

Texas faces unique challenges including Formosan termite colonies in the Gulf region, fire ant infestations across most of the state, extreme heat that drives pests indoors, a long warm season that keeps pests active year-round, and a diverse geography ranging from humid coastlines to arid deserts, each with different pest pressures.

What is heat treatment for pests?

Heat treatment involves raising the temperature of an infested area to 130–145°F using industrial heaters. It is the most effective treatment for bed bugs and can also treat drywood termites in localized areas. The high temperature kills all life stages including eggs. No chemicals are used, and rooms can typically be re-occupied the same day.
