Permit Requirements in Cost
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, pest control is regulated at the state level by the Texas Department of Agriculture (TDA) under the Texas Structural Pest Control Act. Any person or business applying pesticides for hire must hold a valid Commercial Applicator License or Non-Commercial Applicator License from the TDA.
Local municipalities may also impose business license or registration requirements. Because Cost is an unincorporated community in Gonzales County, county-level regulations may apply in addition to state requirements.
When Permits Are Required
A permit or license is typically required for the following pest control activities:
- Applying any restricted-use or state-limited-use pesticide for hire
- Performing structural pest control (termite treatments, fumigation, general indoor/outdoor pest management)
- Operating a pest control business serving commercial properties such as restaurants, warehouses, schools, and office buildings
- Using fumigants or any pesticide classified as a 'dangerous' substance by the TDA
- Performing wood-destroying insect (WDI) inspections for real estate transactions
Common Exemptions
Certain activities may not require a TDA applicator license:
- A homeowner applying general-use pesticides on their own residential property
- Routine janitorial or maintenance work that uses only non-toxic pest control methods (traps, exclusion, sanitation)
- Agricultural pesticide applications on farms or ranches, which fall under separate TDA agricultural rules
- Licensed veterinarians applying pesticides directly to animals
Even when a license is not required, all pesticide use must follow label directions. Local business license requirements may still apply.

Permit Process
1. Verify Contractor Licensing
Ask the pest control company for their TDA Commercial Applicator License number and verify it through the Texas Department of Agriculture's online license lookup. This ensures the business is authorized to apply pesticides in Texas.
2. Request a Service Plan & Pesticide List
A compliant pest control company should provide a written service agreement detailing the pest to be controlled, the pesticides to be used, application methods, and any precautionary notices. Review this before work begins.
3. Confirm Insurance Coverage
Licensed pest control operators in Texas are required to carry liability insurance. Ask for proof of insurance and verify it covers pesticide application and any potential property damage.
4. Check Local Business Licensing
Contact Gonzales County or the City of Cost municipal office (if applicable) to ask if a local business license or registration is required for pest control operators working in the area. Some counties have additional registration requirements.
5. Review Post-Treatment Requirements
After treatment, the applicator must provide you with a written notice (often a door hanger or form) listing the pesticide used, the active ingredients, and any re-entry or re-occupancy restrictions. Keep this document for your records.
Compliance Tips
- ✓ Always verify a pest control company's TDA license number before hiring — you can check it online through the Texas Department of Agriculture's license search tool.
- ✓ Request a written pest control plan before treatment begins. Compliant companies will clearly document the pest, treatment method, and products used.
- ✓ Keep all service records and pesticide labels provided after treatment. These documents are important for your records and may be needed for real estate transactions or warranty claims.
- ✓ Be cautious of companies offering 'no-license-needed' services or heavily discounted rates without providing license information — this is a red flag for unlicensed operation.
- ✓ If you have pets, children, or sensitive individuals in the home, ask about low-toxicity options and re-entry times before any treatment is applied.
- ✓ For commercial properties (restaurants, daycares, offices), additional compliance requirements under the FDA Food Code or OSHA may apply — ensure your pest control provider is familiar with these standards.
Special Considerations
HOA Rules
If your property in or near Cost is part of a homeowners association (HOA), the HOA may have additional rules regarding pesticide application, notification of neighbors, or advance approval for exterior treatments. Some HOAs restrict visible pest control equipment or require landscaping-friendly treatment methods. Review your HOA covenants before scheduling service.
Zoning
Pest control businesses operating in Cost must comply with Gonzales County zoning regulations. Commercial pest control operations may face restrictions on storage of pesticides, waste disposal, and vehicle parking in residential zones. If you're a business owner, verify that your operational location and service routes comply with local zoning and land-use ordinances.
Historic Properties
If your property is listed on or eligible for the National Register of Historic Places, or located in a designated historic district, special care may be needed. The Texas Historical Commission may need to review treatment plans for wood-destroying insects or fumigation to protect historic materials. Always ensure pest control methods are compatible with historic preservation guidelines.
