Permit Requirements in Castell
Know when you need a permit to ensure your project is legal and safe
General Rules
In Texas, anyone applying pesticides for hire — including residential and commercial pest control — must hold a valid license from the Texas Department of Agriculture (TDA). This applies to both general pest control (roaches, ants, spiders) and more specialized treatments (termites, rodents, weeds).
Unlicensed individuals cannot legally apply restricted-use pesticides for pay. Even for general-use products, many local and state regulations require certified applicators for commercial or residential pest control services.

- Any commercial pest control service performed for a fee, including general household pest treatments
- Termite inspections, treatments, and fumigations
- Rodent control services using bait stations or chemical applications
- Mosquito control spraying or fogging on residential or commercial properties

- Structural fumigations in homes, apartments, or commercial buildings
- Businesses or landlords treating common areas in multi-unit properties
Common Exemptions
- Homeowners applying over-the-counter pesticides on their own property (no permit needed)

Permit Process
Confirm Licensing Requirements
First, determine whether the pest control service requires a certified applicator license. In Texas, commercial pest control businesses must employ licensed applicators certified by the TDA. Verify that any professional you hire holds a current TDA Structural Pest Control license.
Check Local Llano County Rules
Castell is an unincorporated community in Llano County, so county-level regulations may apply. Contact Llano County's environmental health or code enforcement office to check for any local pesticide application ordinances, setback requirements, or notification rules.
Request Proof of Insurance and Licensing
Before any work begins, ask the pest control provider for proof of their TDA license, liability insurance, and workers' compensation coverage. Licensed professionals are required to carry these and should provide them upon request.
Review the Treatment Plan and Notice
Licensed applicators must provide a written pest control agreement or service plan before treatment. This document should outline the pests being treated, the products to be used, and any safety precautions. Review it carefully before giving consent.
Document Post-Treatment Compliance
After treatment, the applicator should leave a detailed service record including the date, products used, application method, and any re-entry precautions. Keep these records for your files — they may be needed for future inspections or property disclosures.
Compliance Tips
- ✓ Always verify a pest control company's TDA license by checking the Texas Department of Agriculture's online license lookup tool before hiring.
- ✓ Ask for a written service agreement that clearly states the treatment plan, products used, and any re-entry or safety precautions.
- ✓ Keep all service records and receipts — they serve as proof of compliance and may be needed for property sales or warranty claims.
- ✓ If you're a landlord or property manager, remember that you may need a licensed applicator to treat common areas, even if tenants handle their own units.
- ✓ Be cautious of unlicensed operators offering cash-only pest control — unlicensed work can lead to fines and liability if something goes wrong.
- ✓ For termite treatments or fumigations, confirm that the company holds specific endorsements on their TDA license for those specialized services.
Special Considerations
HOA Rules
If your Castell property is part of a homeowners' association, the HOA may have additional rules about exterior pesticide applications, notification to neighbors, or pre-approval for termite treatments. Always check your HOA covenants before scheduling pest control work.
Zoning
Pest control operations serving commercial properties in Castell must comply with Llano County zoning regulations. Agricultural exemptions may apply for properties zoned for farming or ranching. Commercial applicators storing pesticides on-site may need additional permits for chemical storage and handling.
Historic Properties
Castell and Llano County contain historic structures and properties. For any pest control work on a designated historic building or property, additional review may be required. Treatment methods may need to be approved to avoid damage to historic materials. Consult with the Llano County Historical Commission if your property has historic designation.
