Texas Pest Control License Types and Permitted Treatments

If you operate or hire in Texas structural pest control for compensation, permission is not a single "pest license." The Texas Department of Agriculture (TDA) Structural Pest Control Service (SPCS) issues location-based business licenses, certifies individuals at multiple tiers, and assigns authority through seven official license categories defined in 4 TAC §7.124. What a person may inspect or treat depends on which categories appear on their technician or certified applicator license - and whether the business location holds a valid Structural Pest Control Business License listing those same categories with at least one actively licensed certified applicator on staff.

This guide is for owners, Responsible Certified Commercial Applicators (RCAs), technicians planning category expansion, property managers evaluating vendors, and out-of-state firms mapping Texas services to credentials. It focuses on permitted treatments and credential scopes - not business formation, insurance filing mechanics, or launch marketing. For those topics, see the Texas startup guide and sibling Phase 2 pages on licensing requirements, insurance, renewals, reciprocity, and technician employment.

Texas uses an agriculture-department licensing model under the Structural Pest Control Act (Texas Occupations Code Chapter 1951) and 4 Texas Administrative Code Chapter 7, Subchapter H. Occupations Code §1951.201 makes TDA the sole authority for licensing persons engaged in structural pest control for compensation. Unlike states that split general-use and restricted-use pesticide authority into separate subcategory examinations, Texas organizes permissions around service-type categories - Pest Control, Termite and Wood Destroying Insect Control, Lawn and Ornamental, Weed Control, Structural Fumigation, Commodity Fumigation, and Wood Preservation. Federal label law always applies: the pesticide label is the law regardless of Texas category. Texas adds business licensing, insurance, training, examination, supervision, and category-matching rules on top.

Geography shapes how Texas operators use these categories in practice. Gulf Coast markets around Houston drive year-round Pest Control volume plus Termite and Wood Destroying Insect Control for subterranean and Formosan termite programs. North Texas suburban growth corridors support recurring Pest Control routes, fire ant work that may implicate Lawn and Ornamental, and steady termite inspection demand across Dallas - Fort Worth. Central Texas Hill Country operators field scorpion and spider calls under Pest Control while termite baiting and liquid barriers require the termite category. West Texas and Panhandle operators may run leaner menus on Pest Control before adding specialized fumigation or wood preservation lines. Category authority is statewide; your service menu should reflect both TDA rules and the pests your territory actually generates revenue from.

Texas structural pest control permissions stack in layers: the business location must hold the correct license with current insurance and a designated RCA; certified applicators and technicians must hold category-matched individual licenses; apprentices must train under supervision until they pass technician exams. Understanding this hierarchy prevents a common compliance error - a company displays a valid Structural Pest Control Business License while advertising termite treatments, structural fumigation, or lawn programs that no certified employee is category-qualified to perform.

Structural Pest Control Business License. Required for any person engaged in structural pest control for compensation (Occupations Code §1951.301; 4 TAC §7.121(a)). A separate business license is required for each business location, including branch offices. The license may reflect only those categories in which at least one certified applicator is actively licensed at that location. A business licensee may not operate at any time without a designated Responsible Certified Commercial Applicator and current general pest control liability insurance meeting 4 TAC §7.123. The license is not transferable (Occupations Code §1951.314). Holding a business license authorizes the firm to operate commercially - it does not by itself expand category authority beyond what certified applicators and properly supervised technicians hold.

Responsible Certified Commercial Applicator (RCA). Each business location must designate and notify one certified commercial applicator responsible for training and supervision of all pest control operations at that location. An individual may serve as RCA for only one business license location at a time, even if the same person holds certified applicator credentials employed at other locations. The RCA provides general supervision; certified applicators perform services without direct supervision in their licensed categories; technicians work under direct supervision.

Certified Commercial Applicator. A person licensed in at least one category who can perform pest control services, identifications, and control measures without direct supervision but under the RCA's general supervision. Certified commercial applicators must pass the general standards examination plus appropriate category examination(s) at 70% or higher and meet an eligibility pathway in 4 TAC §7.126. They may provide services only in categories on their license. A certified commercial applicator must hold a separate license for every business for which they are employed but is not required to hold a separate license for branch offices of the same employer.

Technician License. Technicians are licensed by category and perform pest control services under the direct supervision of a certified commercial or noncommercial applicator. Technicians enter through apprentice registration, complete Department-approved training including a six-hour technician training course, document on-the-job and classroom hours, pass category examinations at 70%+, and renew annually with eight hours verifiable training per calendar year under 4 TAC §7.133. Technicians may provide services only in categories on their technician license.

Apprentice Registration. Apprentices are sales or service employees registered to complete technician training who have not yet passed a technician exam. Registration must occur within ten days of beginning employment or training. Apprentices may work only for the business or noncommercial entity for which they are registered and are subject to strict supervision rules during training. Registration expires at the end of the month one year from the month employment began; the apprentice must pass technician exam(s) before expiration.

Certified Noncommercial Applicator and Responsible Certified Noncommercial Applicator. A separate track serves in-house pest control at qualifying entity types - governmental entities, apartment buildings, day care centers, hospitals, nursing homes, hotels, motels, lodges, warehouses, food-processing establishments, schools, and other noncommercial entities under Occupations Code §1951.303 and 4 TAC §7.121(d) - (e). Noncommercial applicators perform services without direct supervision in licensed categories; a Responsible Certified Noncommercial Applicator oversees training, supervision, and records for noncommercial apprentices and technicians. This track does not replace a commercial business license when services are sold for compensation to third parties.

Texas does not use a standalone "general-use only" technician credential comparable to some states' general-standards-only certification. Instead, individual licensing authority flows through category examinations tied to defined scopes in 4 TAC §7.124, with a general standards examination required for certified commercial applicator candidates.

Certified commercial applicator path. Candidates must pass the general standards examination plus one or more category examinations at a minimum score of 70% (4 TAC §7.125). They must also satisfy an eligibility pathway in 4 TAC §7.126 - such as verifiable industry employment including technician time, out-of-state experience verified by letter from the licensing entity, a qualifying biological-sciences credential, Department-approved training, or a previously held verified license. Each category a certified applicator wishes to hold requires passing that category's examination. Exam scores are valid for twelve months. The examination fee is $64 per category under 4 TAC §7.128.

Technician path. Technicians do not take a separate "general standards only" license that authorizes all Pest Control work without category exams. They complete apprentice registration and training, pass category examination(s) at 70%+, and receive a technician license limited to those categories. To add a category after initial licensing, technicians must complete forty hours on-the-job training and eight hours classroom training recorded on TDA's verifiable training record before testing (4 TAC §7.133(c)).

How this differs from product-tier thinking. Operators sometimes assume that because a product is sold at retail or used on a "standard" residential job, no category credential beyond informal training is needed. That fails whenever the inspection or control activity falls outside the categories on the applicator's or technician's license. A technician licensed only in Pest Control cannot perform termite treatments, structural fumigation, or industrial wood preservation even if the product label might otherwise allow a licensed person to apply it. The business license category list must align as well: if no certified applicator at the location holds Termite and Wood Destroying Insect Control, that category cannot appear on the business license and the location cannot commercially offer those services.

Supervision and category matching. Certified applicators may perform services in their licensed categories without direct supervision. Technicians require direct supervision by a certified applicator and may work only in shared categories. Apprentices require supervision appropriate to their training stage and may not operate independently. The RCA must ensure training, supervision, and records comply with Subchapter H rules. Operating out of category - dispatching a Pest Control technician to a termite job, or advertising fumigation without Structural Fumigation credentials - is an enforcement violation regardless of product availability.

For service-line planning, the Pest Control category supports a broad Texas menu of structural and nuisance pests when labels cooperate: cockroaches, ants, spiders, fleas, ticks, flies, mosquitoes, rats, mice, and many occasional invaders in and around structures. It does not replace Termite and Wood Destroying Insect Control for WDO work, Structural or Commodity Fumigation for fumigant programs, Lawn and Ornamental for defined plant pest work, Weed Control for rights-of-way and structural-adjacent weed programs, or Wood Preservation for industrial preservative treatment of poles, crossties, and similar products.

TDA issues pest control licenses in one or more of seven categories. Official names and scopes below follow 4 TAC §7.124 as reflected in the Texas facts pack. Product choice must still match the federal label; category licensing is necessary but not sufficient without label compliance, business licensing, insurance, and supervision rules.

Pest Control. Scope: inspection or control of pests in and around structures or pest animals which may invade homes, restaurants, stores, and other buildings, attacking their contents or furnishings or being a general nuisance, but do not normally attack the building itself. Official examples include cockroaches, silverfish, ants, fleas, ticks, flies, mosquitoes, rats, mice, skunks, raccoons, and opossums. This is the workhorse category for most commercial residential and light commercial route work - German cockroach clean-outs, ant perimeter programs, rodent control, mosquito treatments around structures, and bed bug programs when conducted within this scope. It explicitly excludes termites and wood-destroying insects (Termite and Wood Destroying Insect Control), fumigation (Structural or Commodity Fumigation categories), and industrial wood product preservation (Wood Preservation). Listing skunks, raccoons, and opossums as example pests does not grant unrestricted wildlife authority; see limitations below.

Termite and Wood Destroying Insect Control. Scope: inspection or control of termites, beetles, or other wood destroying insects and wood preservation by means other than fumigation in buildings, including homes, warehouses, stores, docks, or any other structures. Includes treatment of termites in trees in and around structures. Subterranean termite liquid and bait systems, drywood termite programs where applicable, wood-destroying beetle treatments, and non-fumigation structural wood preservation fall here - not under Pest Control. Texas operators in Gulf Coast, Central Texas, and North Texas termite markets should treat this as a distinct business line with WDIR (Wood Destroying Insect Report) workflow, graphing discipline, and insurance that covers termite operations. Real-estate-driven termite marketing without this category on both the business license and field staff licenses is a high-enforcement-risk mismatch.

Lawn and Ornamental. Scope: inspection or control of pests or diseases of trees, shrubs, or other plantings in a park or in and around structures, business establishments, industrial parks, institutional buildings, or streets. Suburban Texas routes often bundle general Pest Control with turf and shrub programs, but Lawn and Ornamental is a separate category requiring its own examination and CEU category units for certified applicators. Fire ant mound treatments in ornamental beds, shrub insect programs, and tree injection work in defined contexts may require this category rather than Pest Control alone - match the work to Code language before assuming Pest Control covers all outdoor pesticide applications.

Weed Control. Scope: inspection or 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. Weed control along fence lines, industrial yards, and municipal rights-of-way belongs here - not in Pest Control or Lawn and Ornamental. Companies offering vegetation management alongside pest routes need this category on staff and on the business license if they perform the work commercially.

Structural Fumigation. Scope: inspection or control of pests through fumigation of structures not primarily intended to contain food, feed, or grains. Structural fumigation is operationally distinct from route pest control: sealing, tarping, aeration monitoring, placarding, notification, and emergency response planning. TDA requires electronic notifications for covered pre-construction and structural fumigation treatments through its designated system. A firm with Pest Control and Termite categories cannot legally conduct structural fumigation without Structural Fumigation credentials on both individual licenses and the business license.

Commodity Fumigation. Scope: inspection or control of pests through fumigation of processed commodities, raw agricultural commodities, or structures normally used to contain commodities. Explicitly excludes fumigation of agricultural equipment or any agricultural commodity located on the farm. Grain bins, warehouse commodity fumigation, and related programs require this category - not Structural Fumigation. Operators serving agribusiness, food storage, and logistics clients must distinguish commodity scope from structural scope when staffing and advertising.

Wood Preservation. Scope: pest control involving addition of preservatives to wood products to extend life by protecting from damage caused by insects, fungi, and marine borers. Examples include crossties, poles, and posts. Includes re-treatment of power-line poles with wood preservative pesticides including fumigants. This category serves utility, railroad, and industrial wood treatment contexts - not the same as Termite and Wood Destroying Insect Control's non-fumigation structural wood preservation language. Pole and crosstie contractors must hold Wood Preservation; structural termite companies must hold Termite and Wood Destroying Insect Control.

Technicians and certified applicators may hold multiple categories. Each additional category requires passing that category's examination (and for technicians adding categories after initial licensing, completing the required supplemental training before testing). The business license may list a category only when at least one certified applicator at that location actively holds it.

Texas draws a bright line between for-hire structural pest control and qualifying in-house programs at specified entity types.

Commercial track. If you sell pest control services to homeowners, landlords, restaurants, schools, warehouses, property management companies, or any third party for compensation, you need a Structural Pest Control Business License for each business location under Occupations Code §1951.301, a designated Responsible Certified Commercial Applicator at all times, and current general pest control liability insurance meeting 4 TAC §7.123 minimums ($500,000 per occurrence and $1,000,000 annual aggregate on the ALS-1101 certificate form for policies effective on or after January 1, 2024). The business license reflects only categories in which at least one certified applicator is actively licensed. Technicians perform work under direct supervision; certified applicators work in their licensed categories under the RCA's general supervision.

Noncommercial track. Certified noncommercial applicator licenses serve employees of governmental entities, apartment buildings, day care centers, hospitals, nursing homes, hotels, motels, lodges, warehouses, food-processing establishments, schools, educational institutions, and other noncommercial entities who perform in-house structural pest control without holding commercial applicator licenses (Occupations Code §1951.303; 4 TAC §7.121(d)). A Responsible Certified Noncommercial Applicator oversees training, supervision, and records for noncommercial apprentices and technicians. Noncommercial entities do not obtain a Structural Pest Control Business License for in-house work - they use the noncommercial applicator framework instead. Technicians and apprentices on this track still need category-matched licenses and appropriate supervision.

Restricted category expectations on both tracks. Category definitions in 4 TAC §7.124 apply regardless of commercial or noncommercial status. An apartment maintenance team treating units with pesticides needs appropriate categories on noncommercial applicator and technician licenses; a hospital facilities department running a rodent program needs Pest Control category authority. Noncommercial status does not expand category scope beyond examinations passed.

Common cross-track mistakes. A property management subsidiary treats only its own portfolio but sells services to outside HOAs for a fee - commercial business licensing may be required. A "consultant" applies pesticides for compensation without a business license. An in-house school district team performs pest control without noncommercial applicator credentials. A commercial license holder dispatches technicians to categories not on their licenses. A noncommercial applicator performs side jobs for neighbors for pay - commercial licensing applies. Each mistake confuses entity authorization with individual category authority or compensation rules.

Use this matrix as an operator planning tool. It states Texas credential layers only; federal labels, contract scope, local ordinances, and separate trades (wildlife, HVAC, repairs) may add requirements.

Recurring residential general pest (ants, roaches, spiders, wasps, scorpions). Commercial: Structural Pest Control Business License listing Pest Control + certified applicator and technicians licensed in Pest Control + insurance + RCA. Non-commercial in-house: certified noncommercial applicator and technicians with Pest Control category.

Rodent control in and around structures. Commercial: business license with Pest Control category on business and individual licenses. Snap traps and non-pesticide methods may not require pesticide licensing but for-hire structural pest control still triggers business license rules when pesticides are part of the program.

Mosquito treatments around homes and businesses. Pest Control category when inspection and control fall within §7.124(1) scope around structures. Confirm product labels and any local mosquito district rules separately.

Subterranean termite liquid or bait systems. Commercial: business license listing Termite and Wood Destroying Insect Control + certified applicator and technicians licensed in that category + insurance covering operations. Not authorized under Pest Control alone.

Wood Destroying Insect Report (WDIR) inspections and real-estate termite work. Termite and Wood Destroying Insect Control category on all performing and supervising licensed staff; business license must list the category.

Bed bug treatments in apartments, hotels, or homes. Typically Pest Control category when treating pests in and around structures; heavy commercial accounts may require documented IPM plans. Business license required for for-hire work.

Fire ant and ornamental shrub programs in suburban yards. May implicate Lawn and Ornamental rather than Pest Control alone when work targets plant pests and diseases in defined ornamental contexts - match job scope to §7.124(3) language.

Rights-of-way and industrial weed control. Weed Control category; not Pest Control.

Tent fumigation of a residential or commercial structure (non-food-primary). Structural Fumigation category on all staff performing the work; business license must list Structural Fumigation; TDA electronic notification requirements apply to covered treatments.

Grain bin or warehouse commodity fumigation. Commodity Fumigation category - not Structural Fumigation. Excludes on-farm agricultural commodity fumigation per rule.

Utility pole or crosstie preservative treatment. Wood Preservation category - including re-treatment of power-line poles with wood preservative pesticides including fumigants. Distinct from Termite and Wood Destroying Insect Control structural work.

General-use-only startup route. Commercial business license listing Pest Control + RCA + certified applicator(s) and technicians licensed in Pest Control + insurance. Add categories before marketing termite, fumigation, lawn, weed, or wood preservation lines.

When expanding menus, complete training, pass examinations, update individual licenses, ensure a certified applicator at the location holds the new category, amend the business license category list, and adjust insurance and CEU tracking before purchasing category-specific products or scheduling jobs. Examination fee is $64 per category; certified applicator original and renewal license fee is $125; business license original and renewal is $300 under 4 TAC §7.128.

Texas structural pest control credentials authorize inspection and control within Act, Occupations Code, and 4 TAC bounds. They do not grant universal "pest" or "wildlife" authority.

Wildlife beyond pesticide scope. Pest Control lists skunks, raccoons, and opossums as example nuisance pests, but live trapping, relocation, and many exclusion-only wildlife businesses may fall under Texas Parks and Wildlife Department rules, local ordinances, or separate nuisance wildlife control licensing - not TDA category exams alone. Native protected species, bat colonies in protected contexts, and bird species beyond structural nuisance scenarios implicate other laws. Marketing "wildlife control" based on a Pest Control category alone without confirming legal authority for the specific method (live trap, relocate, lethal control) is a permissions and customer-trust risk.

On-farm commodity fumigation exclusion. Commodity Fumigation explicitly excludes fumigation of agricultural equipment or agricultural commodity located on the farm. Ag operators near Amarillo, Lubbock, or Rio Grande Valley production areas need distinct regulatory paths for on-farm work.

Structural vs commodity fumigation firewall. Structural Fumigation and Commodity Fumigation are separate categories with separate examinations. Cross-advertising without both credentials violates category rules.

Business license vs individual category. A valid Structural Pest Control Business License does not authorize treatments in categories absent from both the business license and the performing technician's or applicator's license. The RCA must hold certified applicator credentials but category authority still flows from individual category licenses across the team.

Insurance and service scope. Commercial business licensees must maintain general liability insurance meeting 4 TAC §7.123 for structural pest control operations. Occupations Code §1951.312 also describes a bond/security alternative at statute level - confirm current TDA acceptance paths before relying on bond in lieu of insurance. Performing services excluded from coverage creates business and compliance risk even when staff hold correct categories.

Reciprocity does not expand categories automatically. Under Occupations Code §1951.306, waiver and endorsement are discretionary - not automatic upon showing an out-of-state credential. Endorsement requires establishing Texas residence and department determination that out-of-state examination qualifications meet Texas standards. Waiver and endorsement do not replace business license, insurance, RCA designation, or category-specific licensing. No official source reviewed authorizes structural pest control for compensation in Texas before required Texas credentials and insurance are in place.

Apprentice and technician supervision. Apprentices may not perform pest control without appropriate licensed supervision during training. Technicians cannot exceed their licensed categories even when a certified applicator supervisor holds broader categories - the technician's license is the field ceiling.

Separate trades. Home repair after termite damage, structural engineering, HVAC fumigation unrelated to TDA categories, and purely mechanical wildlife exclusion without pesticides may fall outside structural pest control licensing. Category authority and insurance must match the services on your price book.
