Pest Control
Ask three pest control companies what a job costs and you will get three numbers, sometimes with a gap wide enough to make you assume someone is trying it on. Usually nobody is. Pest control is one of the trades where the same address genuinely supports very different quotes, because the price is assembled from a handful of inputs that are never printed on the invoice, and because two technicians can walk the same property and reach different conclusions about what is actually happening in it.
This page carries no dollar amounts. Not because the numbers are secret, but because a figure lifted from a national average is worse than useless when the inputs below vary this much between one metro and the next, and between two houses on the same street. What travels is the anatomy: which inputs exist, which ones move the number a lot, and which ones homeowners worry about that barely move it at all. For real local figures, our Phoenix partner publishes what pest control actually runs in the Phoenix area, priced against the market they work in rather than against a countrywide blend.
Every pest control price, however it is presented to you, is the sum of four judgements the company made before writing it down. What the pest is. How far it has already got. What the building and the lot make necessary. And what finishing the job is going to mean in visits. Change any one of those and the number moves, which is precisely why quotes diverge: the four judgements are made by people, from an inspection, and people inspecting the same house do not always see the same house.
Take them in order, because they are roughly in order of how much they matter.
Species is the single biggest lever, and it is bigger than most homeowners expect, because species does not just change the product - it changes the entire shape of the work. Something that responds to a perimeter treatment and a follow-up is a fundamentally cheaper job than something that requires interior work, or void treatment, or a sequence timed to a life cycle, or heat, or exclusion carpentry. Two pests that look equally unwelcome in the kitchen can sit at opposite ends of the price range purely because of how they have to be dealt with.
This is also where misidentification does its damage. Getting the species wrong does not merely waste one treatment; it wastes the interval, because you find out it failed only after the time it should have taken to work. The National Pesticide Information Center's guidance on where to start with a pest problem puts identification ahead of product choice for that reason, and a company that quotes without telling you what it thinks you have is quoting on an assumption you have not been shown.
When you are getting quotes, the useful question is not what will you use. It is what do you think this is, and what would change your mind. A technician who answers that well is inspecting. One who cannot is guessing, and you are being asked to pay for the guess.
The second lever is population and harborage - how established the problem is, and whether it is living where you are seeing it. A few individuals arriving from outside is a boundary problem. A breeding population inside the structure is a different job with a different price, because knocking it down takes more product, more placements and more return visits before it is genuinely finished rather than temporarily quiet.
Homeowners systematically underestimate this one, because the visible evidence scales very badly with the actual population. You see what wanders into the open. What matters commercially is what is behind the appliance, in the wall void, under the slab edge or in the garage boxes you have not opened since you moved in. This is the input most likely to make an honest quote higher than the one you were hoping for, and it is also the input a company cannot properly assess without being allowed to look properly.
Third comes the property itself, and here the intuition most people bring is wrong. Interior square footage is a weak driver. The perimeter, the construction and the surroundings are strong ones.
The treatable boundary is what gets serviced, so a long perimeter costs more to treat than a short one regardless of how many bedrooms sit inside it. Construction decides how many routes exist: slab edges, expansion joints, block wall cavities, weep holes, attached garages, crawl spaces and utility penetrations are all entry infrastructure, and a house with more of them needs more attention per visit. Surroundings decide the pressure: a lot that backs onto open desert, a wash, a greenbelt or a neighbouring property with its own untreated problem is under constant re-supply, and treating it is closer to holding a line than clearing a room.
Access is the quiet part of this. If the technician can walk the full boundary, the job is priced on the work. If half the perimeter is behind locked gates, stored material, dense planting or a dog, the job takes longer and either the price reflects it or the service quietly does not happen along that stretch.
The fourth input is how many visits it takes before the problem is resolved rather than suppressed - which for most pests is more than one, because the treatment lands on the population that is present and the cycle keeps producing for a while afterwards. This is why an initial service and an ongoing service are different numbers, and why the initial one is usually the larger.
Whether the ongoing part should continue indefinitely is a separate argument with a genuine case on both sides, and we have made it at length elsewhere rather than repeating it here - see our breakdown of one-time versus recurring pest control. The point for pricing is narrower: any quote you are comparing has an assumption baked into it about how many visits are included, and if you do not extract that assumption you are not comparing prices at all.
If you want the short version, rank them like this. Species first, because it selects the method and the method is the cost. Establishment second, because it decides how much work the method has to do and how many times. Perimeter and pressure third, because they set the size of the surface being defended and how hard the outside world is pushing on it.
Everything else - the brand of product, the size of the company, whether the technician arrives in a wrapped truck - moves the number far less than any of those three, and is where most homeowner attention gets spent. If two quotes differ and the three inputs above are genuinely identical in both, then you are looking at a margin difference and you can negotiate it like any other. If they are not identical, the cheaper quote is usually cheaper because it is smaller, and finding out how it is smaller is the whole exercise.
Two of the most commonly searched problems sit outside the ordinary perimeter programme, and it is worth knowing why before you read a quote for either.
Rodent work is part pest control and part carpentry. Trapping and baiting handle the animals present; they do nothing about the gap the animals are using, and a rodent job that does not close entry points is buying you a pause. That exclusion work - sealing, screening, hardware over vents and weep points, sometimes roof and soffit repair - is real labour on a ladder, so rodent pricing behaves more like a small building job than like a spray schedule. Cleanup and contamination handling can add another layer again. When you compare two rodent quotes, the question that separates them is almost never the traps; it is how much exclusion is included and whether the company will state where the animals are getting in. Our Phoenix partner handles this as its own service line rather than as an add-on, which is the right structure - see how they scope rodent work in Phoenix.
Cockroach work is priced by species and by how established the population is, and the two big categories behave completely differently. The large outdoor-origin roaches that wander in from sewers, drains and irrigation are largely a boundary and moisture problem. A German cockroach infestation is an interior breeding problem, and it is one of the few residential jobs where a single treatment is nearly always the wrong plan - it typically needs a sequence, plus sanitation changes, plus follow-up, because the population rebuilds from what the first treatment did not reach. A quote for one that has been priced as if it were the other is the most common way a roach job goes wrong, and you can usually detect it by asking which species the price assumes. The same site's cockroach service splits it that way too.
Three costs routinely arrive after the number you agreed to, and none of them is a scam - they are simply outside what a treatment can do.
The first is exclusion and repair, as above: the gap, the vent, the door sweep, the screen. The second is the conditions that made the property attractive in the first place - standing water, irrigation overspray, dense planting against the wall, stored material against the structure, food waste handling. A company can treat around all of that indefinitely, and some will happily do so, but the conditions are what keeps the programme necessary. The third is anything structural, which is a different inspection and a different trade of work altogether; if the concern is termites, do not fold it into a general pest quote - our guide to the early signs of termites covers what to look for and why it is assessed separately.
Reduce both quotes to the same five facts and the comparison becomes trivial. Target pest, by name. Boundary and areas included. Number of visits in the price, and over what period. The ongoing figure after the initial work. Re-treatment terms if it comes back in between.
A company that will not put those in writing is not necessarily dishonest, but it is selling you something you cannot evaluate, and the request is ordinary enough that resistance to it is itself information. The EPA's citizen's guide to pest control and pesticide safety is worth ten minutes before you sign anything, particularly its point that you are entitled to know what is being applied and to ask what the non-chemical alternatives were.
One last piece of advice that costs nothing: get the inspection before you get the price, and treat any company that produces a number without walking the property as having quoted a category rather than your house. The four inputs at the top of this page cannot be assessed from a phone call, and a number produced without assessing them is a placeholder that will be revised on the day - usually upward, and usually while a technician is already standing in your kitchen.
If you are in the Phoenix area and want the local version of all of this, including what the market actually charges, start with how a general pest programme is scoped there.
Usually because they are not quoting the same job, even though you asked both of them the same question. One may have priced a single treatment of the area you pointed at; the other may have priced a perimeter programme with a follow-up built in, or included an interior treatment, or spotted harborage in a place you had not mentioned and priced for it. Species assumptions differ too - a technician who believes you have one kind of ant and one who believes you have another are pricing two different methods. Before you treat the gap as one company being greedy, get both to state the target pest, the areas included, the number of visits and what happens if it does not work. In our experience most of the difference disappears once the two quotes are described in the same terms, and the part that remains is the part worth negotiating.
Very often, and there is a real reason rather than a sales reason. The initial service is where the inspection, the identification and the heavy work happen: knocking down an established population, treating harborage, sealing or recommending exclusion, and setting whatever monitoring the programme uses. Later visits are largely maintenance against re-entry, which takes less product and less time. That is why a programme quoted as a low ongoing figure will usually carry a larger first number, and why comparing only the ongoing figure between two companies tells you very little. Ask for both halves of every quote before you compare anything.
Less than people expect, because the number that matters is usually not interior square footage but the perimeter and what surrounds it. A modest house on a large lot backing onto open desert or greenbelt can be a harder job than a larger house in the middle of a dense block, because the pressure from outside is higher and the treatable boundary is longer. Construction matters too: block walls, slab edges, expansion joints, crawl spaces and attached garages all give pests routes that a technician has to account for. Ask what boundary the quote covers rather than assuming it scales with the size of the house.
You can buy products, but you are usually buying the least important part of the job. What a competent technician sells is identification, placement and timing - knowing which species you actually have, where it is living rather than where you are seeing it, and what its cycle means for when a second treatment has to land. The EPA's own homeowner guidance leads with identification and with trying non-chemical steps first for exactly this reason. DIY is a reasonable answer for a small, correctly identified, early problem. It is a poor answer for anything established, anything structural, and anything where a wrong identification wastes a season.
At minimum: the target pest by name, the areas and the boundary included, how many visits are in the price and over what period, what the ongoing figure is once the initial work is done, and the re-treatment terms if the problem returns between visits. If the company is treating for something structural, get the inspection findings in writing rather than in conversation. A quote that is a single number with a service name above it is not a quote you can compare to anything, and asking for it to be broken out is a normal request that a good company will not resist.
