Most homeowners pick a pest control company the same way they pick a plumber: a Google search, the highest-starred result, the lowest quote. That works fine when the problem is a wasp nest. It works terribly when the problem is termites, scorpions, rodents, or anything else that requires real technical depth and ongoing relationship.
Here’s the framework we use when we vet pest companies. It takes about 20 minutes to apply to a candidate company. The 20 minutes is worth it.
1. Verify the Texas Department of Agriculture license
Every pest control company operating in Texas must hold a TPCL (Texas Pest Control License) issued by the Texas Department of Agriculture. The license number is required on all marketing material, vehicles, and contracts. You can look it up directly at texasagriculture.gov.
What to check: license number is real, license is active, and the categories listed (pest control, termite control, lawn and ornamental) cover what they’re selling you. A company without the right license category for the work they’re proposing is operating outside their license — walk away.
2. Check the certifications stack
The certifications that matter for residential work: QualityPro (industry’s highest accreditation, requires background checks and protocol standards above state requirements) and GreenPro (eco-conscious treatment certification). For commercial work in specific environments: QualityPro Schools, Food Safety, and Health. For technical depth: at least one ACE-certified entomologist on staff (Associate Certified Entomologist via the Entomological Society of America — requires 5+ years documented experience and a comprehensive exam).
What to check: certifications listed on the website should be verifiable via the issuing organization’s registry. NPMA’s QualityPro registry is searchable. ESA’s ACE directory is searchable. If a company claims credentials that don’t appear in the issuing registry, they’re lying.
3. Look at the contract structure
Annual contracts with cancellation fees are standard at the national chains (Orkin, Terminix, Aptive). Service agreements without lock-in are the standard at the best regional companies. Service agreements are better for the homeowner. If the service is good, you’ll stay. If it isn’t, you should be free to leave without a penalty fee.
What to check: read the agreement. Look for “minimum term,” “cancellation fee,” “early termination fee,” and any auto-renew clauses. If a contract has any of these and the company won’t modify them, ask why a quality company needs to lock you in.
4. Confirm the response time guarantee
What you want: same-day response for calls received before some cutoff (typically 3:00 PM). Sub-2-hour response for emergencies. Documented in writing, not promised verbally.
What to check: ask “if I call you at 10 AM with an active pest problem, when does someone show up?” Get a specific answer. Confirm what happens if they miss the window.
5. Confirm the re-service and refund guarantee
What you want: free re-service when pests return between scheduled visits. Full refund if multiple treatments fail to resolve the same problem. Documented in writing.
What to check: read the warranty terms. Look for exclusions (“weather events,” “non-target species”). The best companies have minimal exclusions. The worst companies have exclusion clauses that cover every realistic scenario.
6. Verify technician credentials
Every applicator working in Texas must hold a TDA certification (Certified Applicator or Apprentice). The technician at your door should be able to show you their credential card and license number. The best companies assign one consistent technician to your property; the worst companies rotate strangers through.
What to check: ask the company who will be the assigned technician for your account. Get a name. Ask about that technician’s certifications and years of experience.
7. Review the documentation standard
What you want: written service ticket after every visit, including technician name and license number, date and time, treatment performed, materials used (product name, EPA number, concentration, volume), and conditions observed. For commercial accounts, additional documentation tied to your operating environment.
What to check: ask to see a sample service ticket. If they hand you a generic receipt, that’s your documentation standard. For routine residential service this may be acceptable; for any commercial account or any property where pest control may matter at resale, it isn’t.
The companies we’d call
We applied this framework to every licensed pest control company operating in the Austin metro over the past six months. The companies that pass all seven points are not the cheapest. They are also not the most expensive. The pricing-quality fit at the top of the market is real — and the gap between the top of the market and the bottom is much larger than the price difference suggests.
