Pest control red flags:what to avoid in Phoenix
Updated July 2026
Because pest control is regulated differently than most trades on this site, through the state's Pest Management Division rather than the ROC, it is worth knowing what to check specifically, along with the usual warning signs of a bad operator.
Red flags in a quote or company
Be cautious of a company that cannot provide its PMD Business License information, will not name the specific product or method being used, pressures you into a long-term contract on the first visit, insists on cash only, or uses high-pressure scare tactics about an infestation without a clear inspection first. A legitimate pest control company should be able to explain what pest they found, what they are using, and why.
What's safe to DIY vs. what benefits from a licensed pro
Sealing gaps around doors and windows, removing debris and standing water near the foundation, and store-bought traps or baits for a minor, isolated issue are reasonable for many homeowners. Termite treatment, structural exclusion work, and any recurring or spreading pest problem are better handled by a licensed pest management professional, both for effectiveness and because some treatment products require professional application.
How to verify before you hire
Check the company's PMD Business License and the technician's Certified Applicator credential against the Arizona Department of Agriculture's public records before you sign anything, or check our verify page. If a company cannot provide this information, get a quote from someone else. See our how-to-hire guide for the full list of questions to ask.
Frequently asked questions
How do I know if a pest control company is legitimate?
Ask for their Arizona Department of Agriculture Pest Management Division business license information and verify it against the state's public licensee records. This is a different check than the ROC license search used for most other trades on this site.
Can I treat scorpions or termites myself?
Basic exclusion (sealing gaps, reducing debris) is reasonable DIY work. Chemical scorpion treatment and, especially, termite treatment are generally better left to a licensed pest management professional, since termite products in particular require specific application methods to be effective and termite damage compounds if treatment is delayed or ineffective.
