Short answer
The useful questions are about process rather than price: will the pest be identified before anything is treated, what exactly is in the quoted scope, is the follow-up included, and will you get written findings. Companies that answer those plainly tend to be the ones doing the work properly.
Pest control is an industry where the customer usually cannot evaluate the work directly. You do not see what is in the crawl space, you cannot tell a thorough inspection from a quick one, and the result takes weeks to judge. That makes process questions the best proxy available.
Questions worth asking on the phone
- Will you identify the pest before quoting treatment? Identification first is the single clearest marker of competence. Treatments do not interchange between species.
- What exactly is in the scope? Interior, exterior, crawl space, attic, outbuildings. Vague scope is where disputes come from.
- Is a follow-up included? For roaches, bed bugs, fleas and ants, one visit is rarely the whole job. Included follow-ups say something about how a company prices.
- Do I get written findings? What was found, what was done, and what needs attention from your side.
- What happens if it comes back? The answer tells you whether you are buying a visit or a result.
Reading a quote properly
Compare scope rather than headline numbers. A cheaper quote that covers an interior spray and nothing else is not competing with one that includes the exterior perimeter, the crawl space and a follow-up; it is a different product at a different price.
- Itemised scope beats a lump sum with no detail
- Published market ranges, where they exist, should be presented as planning figures rather than as the company's price
- Inspection and treatment quoted separately is a good sign, especially on termite work
- Repairs and cleanup listed separately from treatment, because they are different trades and different numbers
- Materials named for exclusion work, since foam-only sealing is the most common failure we are called to redo

Warning signs
None of these is proof of anything on its own, and all of them are worth noticing.
- A quote before an inspection on anything structural. Nobody can price termite or exclusion work from a description.
- Pressure to decide today. Pest problems that are genuinely urgent, stinging insects, something biting, get handled urgently; the contract does not need to be signed at the door.
- Only ever one recommendation. A company that always recommends fumigation, or never does, is telling you about its equipment rather than your house.
- Treating open surfaces indoors in a home with children and pets, when bait and crack-and-crevice work would do the job better.
- Reluctance to put findings in writing. If it is not worth writing down, it is hard to hold anyone to.
Questions specific to this area
A company working San Jose should be able to tell you, without hesitating, that the roof rat is the dominant rodent here, that Argentine ants run supercolonies that make repellent sprays counterproductive, and that older neighborhoods carry both subterranean and drywood termite pressure. Local knowledge shows up in how someone describes your problem before they have seen it.
They should also be straightforward about what they will not do. Any honest operator declines some jobs, refers others, and tells you when the right answer is a plumber, a roofer or a carpenter rather than a pest technician.
What reviews do and do not tell you
Reviews are useful for one thing: how a company behaves when something goes wrong. Scan for the negative ones and read the responses rather than counting stars, because every operator has unhappy customers and only some handle them well.
What reviews cannot tell you is whether the crawl space got inspected, whether the right species was identified or whether the sealing used mesh or foam. Those are process questions, and they only come from asking.
The cheapest useful test
Describe your problem on the phone and listen to the questions you get back. Somebody asking when you see it, where, what it left behind and what changed recently is working the problem. Somebody who skips to booking a visit and a price is working the sale.
