How to Choose a Pest Control Company (Without Getting Ripped Off)

I spent four years working for a pest control company before I moved into the publishing side of the industry. I've seen how the sausage gets made. Some of it is great. Some of it is embarrassing. Here's what I wish every homeowner knew before they picked up the phone.

"Exterminator" vs "Pest Control" Means Nothing

There's no legal distinction between these terms. A company can call itself an exterminator, a pest control operator, a pest management professional, or a "bug guy" and hold the exact same license. The word "exterminator" sounds dramatic, which is why smaller companies use it in their Google ads. Larger companies prefer "pest management" because it sounds more corporate. The license, the training, and the chemicals are identical.

What actually matters is whether they hold a valid pesticide applicator license from your state's department of agriculture. Every state requires one. Every state has a public database where you can look it up. If a company can't give you a license number, or if that number doesn't come back valid when you check, walk away. Unlicensed operators are more common than you'd think, especially in neighborhoods with a lot of door-to-door sales.

How to Read Reviews (Most People Do This Wrong)

Ignore 5-star reviews with no text. They're often solicited -- the tech hands you a card after the first visit and says "would you mind leaving us a review?" You haven't even seen results yet. Of course you're going to say something nice.

Look for reviews that mention specific situations. "They found the mouse entry point under the AC line and sealed it with steel mesh" tells you something. "Great service, very professional" tells you nothing. The best reviews describe what the tech actually did and whether the problem came back.

Three-star reviews are the most honest. People who leave 3 stars aren't angry and they're not obligated. They're reporting reality. "Took three visits to get the roaches under control but they're gone now" is more useful than 50 five-star reviews that say "friendly tech." If you're dealing with something specific like bed bugs or termites, filter for reviews that mention your pest by name.

Check the response to negative reviews. A company that responds with "we're sorry you had this experience, let's make it right" is one thing. A company that argues with the customer, blames them, or ignores complaints entirely is telling you exactly how they'll treat you if something goes wrong.

Red Flags That Should Kill the Deal

No written estimate. Any company that won't put the scope of work and price in writing before starting is a company that will surprise you on the invoice. A good company gives you a written estimate after the inspection, before any chemicals go down.

Pressure to sign a contract on the first visit. "This price is only good today" is a car dealership tactic, not a pest control one. Your ant problem will still be an ant problem tomorrow. Take the estimate home, get two more quotes, compare. Anyone who won't let you do that doesn't want you to see what the competition charges.

Vague about what they'll use. Ask what products they're applying and where. A professional will tell you: "I'm putting Advion gel bait in the kitchen, dusting the wall voids with boric acid, and placing IGR discs under the sinks." If the answer is "don't worry about it" or "it's our proprietary formula," that's a tech who either doesn't know what's in the truck or doesn't want you to know.

No inspection before quoting. If someone quotes you a price over the phone for German roaches or rodents without seeing the property, they're guessing. The price for rodent exclusion on a ranch-style house with a crawl space is completely different from a two-story colonial with a complex roofline. A real company sends someone out first.

What a Good First Visit Looks Like

The tech should spend at least 20 minutes on the inspection before touching any equipment. They should look in your attic, crawl space, or basement if it's a rodent or termite issue. They should check behind appliances for roaches. They should walk the exterior perimeter.

After the inspection, they should tell you what they found, what they recommend, what it costs, and what you can expect in terms of timeline. "You've got German roaches in the kitchen, probably came in with groceries, I recommend gel bait plus IGR, two follow-up visits at two-week intervals, total cost $450" is a good answer. "You've got bugs, I'll spray, that'll be $200" is not.

A tech who spends 5 minutes "inspecting" and 20 minutes selling you an annual contract isn't there to solve your problem. They're there to hit a sales quota.

Questions to Ask Before Hiring

What's your state license number? (Look it up yourself afterward.)

What specific products will you apply? (They should name brands and active ingredients, not vague categories.)

How many visits does this treatment require? (One-visit promises for bed bugs or German roaches are a red flag.)

What's your callback or warranty policy? (Good companies will come back for free within 30-90 days if the problem returns.)

Do you carry liability insurance? (They should. Ask for the certificate if something goes wrong -- like a chemical stain on your countertop or a pet reaction.)

Is there anything I need to do to prepare? (If they say "nothing," that's suspicious. Most treatments require some prep. If you're getting ready for a professional visit, our pest-proofing guide covers what to do beforehand.)

One-Time Service vs Annual Contract

Annual contracts make sense if you live in an area with persistent pest pressure. In the Southeast, where you've got roaches, ants, spiders, and mosquitoes most of the year, quarterly service at $40-60 per visit is reasonable. The tech treats the exterior perimeter, checks bait stations, and addresses any new issues.

Annual contracts do NOT make sense if you have a single, one-time pest issue. Found one mouse? You don't need a 12-month rodent plan. You need someone to find the entry point, seal it, set traps, and check back in two weeks. That's a one-time service for $200-400.

Here's the industry secret: the profit margin on annual contracts is massive. A quarterly service plan at $200/year costs the company maybe $40 in labor and materials per visit. That's why the upsell pressure is intense. Some companies pay their techs a commission on contract sales. Keep that in mind.

When Pest Control Is Worth It

German roaches in an apartment or townhome -- absolutely. You can't solve a shared-wall roach problem without professional help. Read our renter's guide to pest control for more on that.

Termites, period. The stakes are too high and the treatment too technical for DIY in most cases.

Bed bugs. The success rate for DIY bed bug treatment is somewhere around 5%. Don't be that statistic.

Any pest where you've tried DIY for two weeks with no improvement. Two weeks is a fair trial period. If the problem isn't getting better, it's getting worse, because most pest populations double every few weeks.

When You're Probably Wasting Money

A couple of sugar ants on the kitchen counter. A $7 pack of Terro bait and a tube of caulk will handle this faster than scheduling and waiting for a service call.

Spiders in the garage. Unless they're brown recluses or black widows, a perimeter spray you apply yourself will do the job. The spiders are there because other bugs are there. Fix the bug problem and the spiders leave.

Stink bugs in fall. No chemical treatment stops them. Caulk and weatherstripping are the only real answers.

A single mouse. Twelve snap traps and an afternoon of sealing entry points costs under $30. A pest control company will charge $200+ for the same result.

The Bottom Line

Get three quotes. Check the license. Read the 3-star reviews. Ask what products they'll use and how many visits it'll take. Don't sign an annual contract for a one-time problem. And if a company won't give you a written estimate, thank them for their time and call the next one.
