One phone call can tell you almost everything you need to know about an exterminator. A strong local pro answers every question clearly. A shaky one starts hedging after the first few. These ten questions cover licensing, treatments, guarantees, and pricing, so run through them before you let anyone treat your home.
Quick answer
Before hiring an exterminator, ask for their license number and proof of insurance, whether the technician is a certified applicator, if they inspect before treating, what products they use and the safe re-entry window, the written re-service guarantee, and the recurring schedule and cancellation terms. How easily they answer tells you as much as the answers.

Questions about credentials
First, make sure the company is legitimate and properly covered. A license protects you legally. Insurance protects you financially if a technician damages something on your property. Any reputable pro answers these without pausing.
- What is your pest control license number, and how can I verify it?
- Is the technician coming to my home a certified or registered applicator?
- Are you fully insured, and does that coverage protect my property during service?
Questions about experience and approach
What makes treatment work is knowing the pest. The more a company understands the species common to your area and the way your specific problem behaves, the better the plan they build.
Their answers also reveal something else. Do they inspect first, or just show up and spray?
- How long have you worked in my area, and do you handle this pest often?
- Will you inspect my property and identify the pest before recommending anything?
- Is the plan customized to my home, or pulled from a standard template?
Questions about treatments and safety
You have every right to know what gets applied in and around your home, and how it affects the people and animals who live there. A trained professional talks through products openly and hands over documentation when you ask.
Get specific. Ask how the products affect children and pets, whether you need to leave during the treatment, and how long before it's safe to walk back into a treated room. A company that turns vague or defensive about chemicals just told you something.
- What products will you use, and will you provide a Safety Data Sheet on request?
- How do these treatments affect children and pets, and what is the safe re-entry window?
Questions about guarantees
Some infestations don't clear in a single visit. A service guarantee is how a good company stands behind its work when that happens. You want a written re-service promise at minimum, plus free callbacks between visits on recurring plans if the pests come back.
Pin down the scope and the length of that guarantee now, before any surprises later. A company confident in its own methods will put it in writing.
- What does your written re-service guarantee cover, and how long does it last?
Questions about pricing and contracts
Transparent pricing is what separates a trustworthy provider from one leaning on lock-in tactics. You want to know the recurring schedule, the cancellation terms, and whether that first inspection is free or quietly credited toward your service.
Watch out for two things. Deep-discount first-visit promos that bind you to a long contract with steep cancellation fees. And recurring auto-billing set up without clear written consent.
- What is the recurring schedule, and what is your cancellation policy?
- Is the first inspection truly free, with a written, no-obligation estimate?
How to read the answers
Notice how easily a company answers, not just what it says. A strong local pro gets through all ten questions without dodging. Plenty of providers handle five or six and then start getting evasive. That gap is exactly what you're testing for.
Then check the answers against recent reviews on more than one platform. When what a company tells you on the phone matches what past customers describe, you've probably found a pro worth hiring.
