Choosing a pest control company is different from hiring most trades, because you are inviting someone to apply regulated chemicals inside the place your family sleeps. That raises the stakes on getting it right, and it is why the EPA publishes its own guidance on selecting a company rather than leaving it to the market.
This guide covers how to verify the licence — which runs through an authority most people never think of — what a genuinely good approach to your problem looks like, the questions worth asking, and the specific sales tactics the EPA tells consumers to walk away from.
Verify the Licence — and Know Who Issues It
Pest control licensing does not sit with a contractor board. A company applying pesticides must employ at least one certified, licensed commercial pesticide applicator, and every other person doing the work must be a certified applicator or a licensed technician working under direct supervision.
Those licences are verified through your State Department of Agriculture. That is the single most useful thing to know here, because “we’re fully licensed” is unverifiable until you know where to check.
The EPA also suggests asking the company directly for three things: their licence, the labels for the pesticides they intend to use, and the application rates. A professional produces all three without hesitation. For rodent work specifically, the EPA adds two more — confirm the company carries insurance, and that employees are bonded, meaning the company reimburses you for damage.
| What to check | Where to check it |
|---|---|
| Applicator licence and certification | Your State Department of Agriculture |
| Complaints about pesticide misuse | State agriculture department, state attorney general, BBB, or the EPA |
| Liability insurance | A certificate from the insurer or agent |
| Bonding, for rodent and trapping work | Ask the company and confirm what it covers |
| Time at the current location | Ask directly — the EPA suggests this as an experience question |
The Approach Matters More Than the Product
Ask a company how they will deal with your problem, and listen for whether the answer starts with inspection or with spraying.
The EPA’s position is that a responsible company provides a service contract built around inspections, applying pesticide only where an inspection shows it is warranted — rather than routine applications on a fixed schedule regardless of what is happening at your property. It also expects a good company to suggest non-chemical control methods where those apply.
That approach has a name in the industry: integrated pest management, or IPM. It means identifying the pest properly, finding out what is attracting or admitting it, using physical and environmental measures first, and applying chemicals in a targeted way where they are actually needed — with monitoring afterwards to see whether it worked. The EPA recommends IPM specifically for bed bug work, where ongoing monitoring is part of the plan rather than an optional extra.
A company that leads with the product rather than the diagnosis is selling you a treatment. A company that wants to inspect first, then tells you which gaps to seal and which leak to fix alongside what they will treat, is solving the problem.
The question that sorts companies fastest
“What will you do before you apply anything, and what would make you decide not to apply it at all?” A company practising integrated pest management has a real answer. A company selling scheduled applications will struggle with the second half of the question.
Match the Company to Your Pest
General pest control and specialist work are different skill sets, and the EPA is explicit about this for the hardest pests.
Bed bugs
Look specifically for a professional experienced in treating bed bug infestations, and check the company’s credentials rather than assuming general pest experience transfers. Expect a plan involving inspection, taking furniture apart where necessary, vacuuming, heat and pesticides — and expect multiple visits, because the EPA notes that very few infestations are controlled with a single treatment. You will also have preparation to do, including laundering and cleaning.
One more point from the EPA that costs people money: do not spend weeks trying to treat bed bugs yourself first, because the delay can let the infestation spread.
Rodents
Ask about exclusion work, not just baiting. Sealing the entry points is what stops the next one getting in, and a company that only sets bait is signing you up for a recurring problem. This is also the category where the EPA’s advice about insurance and bonded employees matters most, since trapping and exclusion work involves crawlspaces, roofs and structural gaps.
Termites
Ask what the guarantee covers, for how long, and what voids it — and whether an annual inspection is required to keep it alive. Termite work is expensive enough that the guarantee is a meaningful part of what you are buying.
Questions to Ask Before You Book
- What is your applicator licence number, and which state authority issued it?
- How long have you operated at this location, and can I speak to two customers with the same pest problem?
- Will a certified applicator do the work, or a supervised technician?
- Can I see the labels and application rates for what you plan to use?
- What will you inspect before deciding on a treatment?
- What non-chemical measures do you recommend alongside it?
- How many visits does this normally take, and are follow-ups included?
- What preparation do I need to do, and how long must people and pets stay out?
- What guarantee applies, how long does it run, and what voids it?
- Does the contract auto-renew, and what notice do I need to cancel?
Raise anything that changes the risk profile before booking rather than on the day: young children, pregnancy, pets, a fish tank, beehives, a vegetable garden, or anyone in the house with asthma or another respiratory condition. Those details should change what gets used and where.
The Tactics the EPA Tells You to Avoid
Several of these are specific to this industry and would not register as warning signs otherwise.
- Pricing by the gallon. The correct amount of pesticide is what the label specifies for the situation, not a volume you are sold.
- Claims of a “secret formula”. Every legally used pesticide carries a registered label. There is nothing secret to have.
- Any claim of government approval or endorsement. Agencies do not endorse pest control companies.
- Package deals and pressure to sign immediately.
- Door-to-door sales, or a company with no listed phone number.
- Warnings of structural damage used to push a treatment. Ask to be shown the damage, and get an independent opinion before agreeing to anything expensive.
The EPA’s framing is worth carrying into the whole decision: judge on quality and value rather than price alone, and take the time to research rather than choosing in a hurry, because a hasty decision here can cost you in health or property terms and not only in money.
Comparing Contracts, Not Just Prices
Two plans at similar annual prices can differ enormously once you read what is in them. Line them up on the same points.
- Which pests are covered, and which are explicitly excluded — termites and bed bugs commonly sit outside general plans.
- How many visits, at what intervals, and whether the first one is priced differently.
- Whether visits are inspection-led or fixed applications.
- Whether call-backs between scheduled visits are free if the problem returns.
- What happens if treatment fails — a repeat at no charge, or a new invoice.
- Interior and exterior coverage, and whether garages, crawlspaces and attics are included.
- Contract length, auto-renewal, price escalation and cancellation notice.
- Whether you receive a written report after each visit saying what was found and what was applied.
That last item is worth insisting on. A record of what was applied where, visit by visit, is what you need if a problem persists, if someone in the house reacts to something, or if you sell the property. If you also want the published price ranges to check a quote against, our breakdown of what pest control costs by pest and service type sets them out.
