How to Vet a Pest Control Company Before Hiring

Pest control involves letting someone into your home who's licensed to apply chemicals around your family and pets — it's worth five extra minutes of checking before you book. Here's exactly what to look at and where to look.

Why does licensing matter for pest control?

Pest control technicians who apply pesticides are required to be licensed or certified in nearly every state, and the company itself usually needs a business license or registration as a pest control operator. Licensing means someone has passed a test on safe, correct pesticide use and is accountable to a state regulatory body if something goes wrong.

An unlicensed operator isn't just a legal risk — it's a practical one. If a treatment is done incorrectly, applied at the wrong concentration, or causes damage, you have far less recourse if the company was never licensed to begin with.

How do I check if a pest control company is licensed?

Most states let you verify a pesticide applicator license online, usually through the state's pesticide regulatory agency — often housed in the department of agriculture or a consumer protection office. Searching "[your state] pesticide applicator license lookup" is typically the fastest way to find it. Enter the company name or the technician's license number (ask them for it directly) to confirm it's active and in good standing.

If you can't find an online lookup tool for your state, ask the company directly for their license number and cross-check it with the state agency by phone — that works just as well.

If a company won't give you a license number when asked, or the number doesn't come up in the state lookup, treat that as a serious red flag — see our guide on pest control scams and red flags for more warning signs.

What insurance should a pest control company carry?

At minimum, look for general liability insurance, which covers property damage or accidents that happen during the job. Many companies also carry workers' compensation, which protects you if a technician is injured on your property. Ask for a certificate of insurance (COI) — a legitimate company can produce this quickly, often by email, without pushback.

Insurance matters most if something goes wrong: a spilled chemical that damages flooring, an allergic reaction, or an injury on your property. Without insurance, you could be left covering those costs yourself.

How do I actually check licenses and insurance? (step by step)

1. Ask for the company's business license number and the technician's applicator license number before scheduling, either by phone or in writing.
2. Look up the license on your state's pesticide regulatory agency website to confirm it's active, not expired or suspended.
3. Request a certificate of insurance showing general liability (and workers' comp, if they have employees) coverage.
4. Confirm the coverage is current, not expired — COIs list effective and expiration dates.
5. Save copies of both documents in case you need them later for a dispute or insurance claim.

Do they actually handle your kind of pest?

This step gets skipped, and it wastes people a lot of time. A license and an insurance certificate tell you a company is legitimate. Neither one tells you the company does your kind of work.

We looked at 18,941 calls from homeowners to pest control companies between January and July 2026, across 13 pest control companies, and tracked how often a caller reached a company that doesn't handle the pest they were calling about:

• Wildlife (bats, raccoons, squirrels): 19.3% of those calls
• Wasps and hornets: 11.2%
• Termites: 10.6%
• Bed bugs: 10.3%
• Cockroaches: 3.8%
• Mice and rats: 3.8%

The pattern is worth knowing before you start dialing. Everyday bug and rodent work is available almost everywhere, but bats, termites, bed bugs and stinging insects are specialist trades — and somewhere between 1 in 10 and 1 in 5 of those callers ended up with a company that couldn't help them.

So name your pest first and ask directly: "Do you handle bats?" or "Do you do termite treatment, not just general pest control?" It takes ten seconds and it can save you a wasted appointment.

How should I read online reviews?

Look past the star rating and read the actual text, especially recent reviews (last 6–12 months) that mention the service you need — a pattern of complaints about no-shows, upselling, or pests returning is more useful than a single bad review. Also check whether the company responds to negative reviews professionally, which is a decent signal of how they'll handle a problem if one comes up with your service.

Be cautious of profiles with only 5-star reviews and no detail, posted in a short burst of time — that pattern can indicate incentivized or fake reviews rather than organic feedback.

What other signals suggest a company is trustworthy?

Beyond license, insurance, and reviews, a few practical signals are worth checking. Does the company have a real physical address and a working landline, not just a cell number? Have they been in business for more than a couple of years — long enough to build a track record locally? Do they show up in your state's business registry under the name they're using to market themselves?

It also helps to notice how the company communicates before you've even hired them. A trustworthy provider answers questions about pricing and process directly, sends written estimates, and doesn't rush you into scheduling same-day work for a non-emergency problem. If a salesperson is more focused on getting a signature than answering your questions, treat that as a signal to slow down and compare other options.

What questions should I ask before booking?

Beyond license and insurance, ask what's included in the price, whether there's a guarantee if pests return, what chemicals or methods they use, and how long the treatment takes to work. Our guide on questions to ask a pest control company covers this in more detail, and our pest control contracts explained guide is worth reading before you sign anything with a recurring plan.

You can browse vetted categories of providers, including exterminators, general pest control, and termite control, or search by city to compare local options.

When to call a professional

If you're dealing with anything beyond a minor DIY-able problem — an infestation, a structural pest like termites, a health-risk pest like bed bugs or rodents, or a recurring issue — it's time to bring in a licensed pro rather than continue troubleshooting yourself. Vetting the company properly up front (license, insurance, reviews) means you're not adding a second problem — an unreliable contractor — on top of the pest issue you already have.
