Every company says they're licensed, thorough and guaranteed. Here are the nine questions that actually tell them apart — and the three answers that should end the call.

Search once and you'll get a dozen options, all claiming the same four things: licensed, experienced, eco-friendly, guaranteed. Picking a pest control company in Kennewick is hard precisely because the marketing is identical — so the only useful approach is to ask questions the weak ones can't answer well. These nine do it in about five minutes on the phone.
Verify the Washington licence, insist on a real inspection before any price is quoted, get the guarantee in writing (free re-service between visits is the standard worth holding out for), read the term and cancellation terms before signing, and be suspicious of any price quoted before someone has looked at your house. If a company can't answer questions 1, 4 and 7 below without hesitating, keep dialling.
This is non-negotiable and it's the fastest filter. Anyone applying pesticides commercially in this state must be licensed through the Washington State Department of Agriculture — a licensed applicator, working for a licensed pest control business. A legitimate company answers this instantly and offers to show you. Hesitation, deflection or "the owner handles all that" is your answer.
Ask about insurance in the same breath. General liability coverage protects you if something is damaged at your property. Any established company carries it and will say so without flinching.
The single biggest quality signal. Pest pressure at a 1,400 sq ft home backing onto farmland near Road 68 is a completely different job from a 3,200 sq ft house on an interior street in Southridge — different perimeter length, different entry points, different species. A company that quotes a firm number over the phone without asking anything about your property is selling a route stop, not a solution.
A ballpark range on the phone is perfectly fine and honest. A final price with no inspection is a flag.
Ask them to identify what they find and explain it. Odorous house ants, pavement ants and carpenter ants look similar to a homeowner and need three genuinely different approaches — bait chemistry, placement, and whether there's structural moisture to address. A technician who says "ants, we'll spray for it" is guessing, and guessing costs you a whole season.
Same for rodents. Deer mice and house mice call for different placement and, in deer mouse country, different cleanup precautions. See 7 Common Pests in Kennewick, WA: Complete Guide for what's actually here.
"Guaranteed" means nothing until you pin down the mechanics. Ask directly:
Free re-service between visits is the standard to hold out for, and plenty of companies here offer it. A "guarantee" that turns out to mean a discounted callback in ten days is not the same product.
This is where most bad experiences in this industry actually start — not with the treatment, with the paperwork. Ask what the term is, what the cancellation fee is, whether the price can change mid-term, and whether it auto-renews. Then read the agreement before you sign it, on your own time.
Term agreements aren't automatically bad — they're often how you get the discounted first visit. But you should know exactly what you're agreeing to, and month-to-month should be available if you want it. We offer month-to-month with no contract for exactly this reason; nobody should feel trapped into pest control.
Continuity matters more than people expect. A technician who has been to your property before knows which corner of the garage the widows keep coming back to, which vent screen failed, that your neighbour's woodpile is the ant source. Companies that rotate a different stranger through every quarter lose all of that, and you end up re-explaining your house four times a year.
Get the initial fee, the recurring price, the frequency, and anything that's extra. The common trap is a headline first-visit price attached to a recurring cost that isn't mentioned until the paperwork.
For reference, here's ours in plain numbers: first visit as low as $149 (a standalone one-time treatment is $249), then $59–109 a month depending on home size, on a monthly, bi-monthly or quarterly schedule. Free re-service between visits. Interior treatment optional. Month-to-month available. Any company should be able to lay theirs out just as plainly.
A good answer sounds specific: cover the aquarium and switch off the pump, keep everyone off interior treated surfaces until dry (1–2 hours), rodent bait only in locked tamper-resistant stations, we'll keep applications off the vegetable beds, and interior work is optional if you'd rather skip it. A vague "oh it's totally safe, don't worry about it" is a worse answer than a careful one. More on that in Is Pest Control Safe for Kids and Pets? 6 Facts.
You can also ask for the product label or safety data sheet for anything applied at your home. The EPA's Citizen's Guide to Pest Control spells out what you're entitled to ask, and a good company hands it over without a fuss.
Local knowledge is not a marketing line here — it's the whole job. Our pest calendar is driven by irrigation and harvest, not by cold weather. A company that plans around the autumn rodent wave from the Columbia Basin harvest, knows which streets back onto canals, and knows that July ant calls are about water rather than food is going to get you a better result than one running a national script. Ask what they expect to find at your address before they've seen it — the answer tells you everything.
One more, softer flag: a quote that's dramatically below everyone else's. In this trade that usually means fewer minutes on site, exterior-only where interior was needed, or a term agreement that recovers it later. Fair pricing beats cheap pricing every time.
Star ratings are close to useless on their own; the text is where the information is. Skip the five-word raves and read the three-star reviews — that's where you learn how a company behaves when something goes wrong, which is the only thing you're really buying. Look specifically for whether they came back, how quickly, and whether it cost the customer anything. Photos in reviews and named technicians are good signs. Two hundred reviews all posted the same month is not.
If you only have time for three questions, use these: Are you licensed in Washington and can I see it? Will someone inspect before quoting? If pests come back between visits, do you return free of charge, in writing? Companies that answer those three well are almost always fine on the rest.

Most Tri-Cities homes land around $149 for a discounted first visit and $59–109 a month for ongoing service, depending on square footage and add-ons. A standalone one-time treatment runs about $249. Anything dramatically cheaper usually means less time on site or a term agreement recovering it later.
Ask the company directly — they should produce it without hesitation — and verify through the Washington State Department of Agriculture, which licenses both pesticide applicators and pest control businesses in this state.
Not with every company. Term agreements are common because they fund the discounted first visit, but month-to-month should be available if you'd rather not commit. Always read the cancellation terms before signing.
Often, yes. A quote well below everyone else's usually means a shorter visit, exterior-only service where interior work was needed, or a term that recovers the difference. Compare total first-year cost, not the headline number.
Two or three is plenty, and it's worth doing. Ask each the same questions so you're comparing like for like — especially the guarantee terms and the total first-year cost.
"If pests come back between scheduled visits, do you come back free of charge — and is that in writing?" It's the question that tells you what happens when things go wrong, which is the part you're actually paying for.
