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. The questions to ask before hiring an exterminator come down to a short, scannable checklist covering license, insurance, guarantee, treatment approach, safety, written pricing, and contract terms. Run through them before you let anyone treat your home.
Quick answer
The key questions to ask before hiring an exterminator: 1) What is your license number? 2) Are you insured and bonded? 3) What is your written re-service guarantee? 4) Do you use an IPM (integrated pest management) approach? 5) How do your treatments affect pets and children? 6) Will I get a written estimate? 7) What are the contract and cancellation terms? 8) Do you have experience with my specific pest? How easily a company answers these tells you as much as the answers themselves.

The 8-question checklist
Print this, screenshot it, or just read it off your phone while you're on the call. Each question is built to surface a different thing: legitimacy, accountability, method, safety, or cost. Work through them in order and pay attention to how smoothly the answers come.
Here's the checklist, then the detail behind each one.
- 1. Are you licensed? Ask for the license number and how to verify it.
- 2. Are you insured and bonded? Confirm your property is covered if something goes wrong.
- 3. What's your guarantee? Get the written re-service and callback terms.
- 4. Do you use an IPM approach? Inspect and target first, spray as part of a plan, not the whole plan.
- 5. Are treatments safe for pets and children? Ask about products and the safe re-entry window.
- 6. Will I get a written estimate? Free, itemized, no-obligation.
- 7. What are the contract and cancellation terms? Schedule, length, and how to cancel.
- 8. Do you have experience with my specific pest? Local track record with your exact problem.
1 and 2: License, insurance, and bonding
Start here, because nothing else matters if the company isn't legitimate. A license means the state holds them to a standard. Insurance protects you financially if a technician damages something on your property, and bonding adds another layer of protection if work is left unfinished or done improperly. Any reputable pro answers these without pausing.
If someone can't or won't give you a license number, that's the end of the call.
- What is your pest control license number, and how can I verify it with the state?
- Are you fully insured and bonded, and does that coverage protect my property during service?
- Is the technician coming to my home a certified or registered applicator?
3: The guarantee and re-service terms
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?
- On a recurring plan, are callbacks between scheduled visits free?
4: The treatment approach (IPM)
What makes treatment work is knowing the pest. The strongest pros lean on integrated pest management, or IPM, which means they inspect, identify, and target the source first, then use products as part of a plan rather than the entire plan. That usually means sealing entry points, removing what's attracting pests, and applying treatment where it actually matters.
Their answer reveals something else too. Do they inspect first, or just show up and spray? A company that builds the plan around your home, not a standard template, is the one you want.
- Do you use an IPM (integrated pest management) approach?
- Will you inspect and identify the pest before recommending anything?
- Is the plan customized to my home, or pulled from a standard template?
5: Pet and child 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?
6 and 7: Written estimate and contract terms
Clear pricing you can read in writing is what separates a trustworthy provider from a vague one. You want a free, itemized, no-obligation estimate, and you want to know the recurring schedule, the length of any agreement, and exactly how to cancel.
Most quality plans pair a discounted or free first visit with an annual agreement, and many include an early-cancellation fee. That's standard: the first treatment costs the most to deliver, so the agreement is what lets a company discount it and still guarantee the work all year. The thing to insist on is that the schedule, billing, and cancellation terms are in writing, and that any recurring auto-billing is set up with your clear written consent.
As a general sense of the range, first general pest visits often run as low as $99 with quarterly service around $45/mo, and one-time jobs land somewhere between $199 and $400. Mosquito setups start around $75 with treatments near $99 each. The exact number should always come back as a free, written quote tied to your specific home.
- Will you give me a free, written, itemized estimate with no obligation?
- What is the recurring schedule, how long is the agreement, and what is your cancellation policy?
8: Experience with your specific pest
A company that treats termites every week is a different proposition from one that mostly does general pest and is taking a swing at your termite problem. Ask how often they handle your exact pest and how long they've worked in your area. Local experience matters, because the species, the seasons, and the construction styles all change the playbook.
The right answer is specific. A pro who handles your pest regularly can describe how the problem usually behaves and what the plan looks like before they've even seen your home.
- How long have you worked in my area, and do you handle this pest often?
- What does a typical plan for this pest look like?

How to read the answers
Notice how easily a company answers, not just what it says. A strong local pro gets through all eight 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.
Or skip the calls and get matched
Working this checklist across three or four companies is real work.
