Permit Requirements in Mertens
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, structural pest control is regulated by the Texas Department of Agriculture (TDA). Anyone who applies pesticides for a fee — residential or commercial — must be a licensed Structural Pest Control applicator. This includes exterminators, termite treatment specialists, and commercial fumigators. Businesses must also carry proper insurance and employ at least one certified applicator who supervises all treatments. Homeowners performing DIY pest control do not need a state license but must still follow all pesticide label directions, which carry the force of law.
When Permits Are Required
A pest control license or permit is required in these situations:
- Hiring a professional pest control company — The company and its applicators must hold valid TDA structural pest control licenses.
- Commercial fumigation — Special certified applicator endorsements are required for fumigation work.
- Termite pre-treatments for new construction — Must be performed by a licensed company with a proper treatment plan filed with the TDA.
- Applying restricted-use pesticides — Only certified applicators can purchase and apply these products.
- Operating a pest control business in Mertens — In addition to TDA licensing, you may need a local business license or permit from the City of Mertens or Hill County.
Common Exemptions
Situations that may not require a permit or license:
- Homeowners applying over-the-counter pesticides on their own property.
- Property owners using general-use pesticides for minor pest issues without hiring a professional.
- Employees of a property owner applying non-restricted pesticides on that owner's land (no fee exchanged).

Important: Even when exempt from licensing, you must always follow label instructions. Violations can result in fines even without a license.

Permit Process
Determine the Type of Work Needed
Identify whether your project requires general pest control (roaches, ants, rodents), termite treatment, or fumigation. Each category may require different applicator endorsements under TDA rules.
Verify the Contractor's License
Before hiring, ask for the company's TDA Structural Pest Control license number. You can verify it through the Texas Department of Agriculture's online license lookup tool to ensure the business and its applicators are current and in good standing.
Check Local Business Requirements
Contact the City of Mertens or Hill County offices to ask if a local business license or permit is needed for pest control operations. Some municipalities require an additional local permit even if the state license is active.
Obtain a Written Pest Control Agreement
Texas law requires licensed pest control companies to provide a written inspection report and treatment plan before starting work. This document should outline the pests, treatment methods, and any warranties.
Confirm Post-Treatment Documentation
Once the work is complete, the applicator should provide a service record detailing what was applied, where, and in what quantity. This documentation is important for compliance and future reference.
Compliance Tips
- ✓ Always verify your pest control provider's TDA license number before any work begins — it's a quick check that protects you and your property.
- ✓ Keep copies of all pest control service records, including inspection reports, treatment plans, and invoices, for at least two years.
- ✓ For termite treatments, ensure the company provides a re-treatment warranty in writing — Texas law has specific requirements for termite control guarantees.
- ✓ If you're a property manager or landlord, remember that tenants must be notified before pest control treatments in multi-unit dwellings.
- ✓ Never purchase or apply restricted-use pesticides without proper certification — doing so can result in significant fines from the TDA.
- ✓ When in doubt about a permit or chemical restriction, call the Texas Department of Agriculture's Structural Pest Control Service or your local Hill County Extension office for guidance.
Special Considerations
HOA Rules
If your property is part of a homeowners' association in Mertens or the surrounding Hill County area, the HOA may have additional rules regarding pest control treatments. Some HOAs require advance notice for exterior spraying, restrict certain chemicals, or require board approval for termite tenting. Always review your HOA covenants and notify your association before scheduled treatments.
Zoning
Zoning regulations in Mertens and Hill County may affect where pest control operations can be based or conducted. Commercial pest control storage of pesticides may be restricted in residentially zoned areas.

Historic Properties
Mertens has historic structures and may have properties listed or eligible for listing on the National Register of Historic Places.
