What does a pest control service do?

A good one inspects first, identifies the pest, finds how it's getting in and what's feeding it, then treats in targeted places (baits, crack-and-crevice sprays, dusts, traps, exterior barriers), seals or recommends sealing entry points, and comes back to check results. A routine quarterly visit is usually much simpler: knocking down webs, spreading granules around the foundation and spraying the exterior perimeter.

How do I choose the best pest control company?

Check the state license (your state pesticide agency can confirm it), get a written inspection and estimate from two or three companies, ask what products they'll use and how many visits are included, read the guarantee and cancellation terms, and skip anyone selling door to door or quoting without looking.

Should I sign up with a door-to-door pest control salesperson?

Pest pros themselves usually say no. Door-to-door crews often sell one- or two-year contracts with cancellation fees around $200, on the strength of claims about your neighbors. If you already signed, act fast: the FTC Cooling-Off Rule generally lets you cancel a sale of $25 or more made at your home until midnight of the third business day, in writing, for a full refund.

Is residential pest control safe for kids and pets?

When products are applied according to the label, mostly in cracks, baits and exterior perimeters, exposure is low. Keep kids and pets away until sprays dry, ask for the product names and EPA registration numbers, and tell the technician about fish tanks, pregnancy and allergies.

Is there non-toxic pest control?

Many problems can be solved with low-toxicity methods: sealing, sanitation, traps, vacuuming, heat, baits in closed stations, boric acid and diatomaceous earth. Ask companies for an IPM or 'green' program; it should mean less pesticide, not no inspection.

How often do you need pest control?

For a specific infestation, usually one to three visits (German cockroaches almost always need more than one). For prevention in warm, pest-heavy regions, many homeowners use quarterly exterior service. In cold climates or homes without recurring problems, you may not need a contract at all.

Big national company or small local one?

Either can be good, but r/pestcontrol technicians repeatedly recommend established local companies: quotes tend to be lower, the owner's reputation is on the line, and there's less pressure to sell contracts. National firms can be the better pick for termite warranties that cover repairs.

Pest Control: How It Works and How to Choose a Company

Pest control is the professional service of finding, treating and preventing insects, rodents and other pests in a home or business, using inspections, targeted pesticides, traps and sealing of entry points. A good pest control company works out why pests are there and fixes that, rather than just spraying baseboards on a schedule.

This page explains what a pest control service actually does, how residential treatment works for common pests, what to ask before hiring, and what to do before and after a visit.

What a pest control service does

Most US companies follow some version of integrated pest management (IPM), the approach the EPA recommends. In practice a first visit looks like this:

Inspection. The technician asks where you've seen activity, then checks kitchens, bathrooms, basements, attics, the exterior and the crawl space. They look for droppings, rub marks, frass, mud tubes, nests and entry gaps.
Identification. German cockroach or American? Pavement ant or carpenter ant? House mouse or Norway rat? The species decides the treatment, and misidentification is the most common reason treatments fail.
Treatment plan. Usually a mix: baits (gel, granular, bait stations), crack-and-crevice sprays, dusts in wall voids, traps, an exterior perimeter band, and sealing.
Sanitation and exclusion advice. Where food, water and gaps are feeding the problem, and what you need to fix.
Follow-up. One or more return visits to check monitors and re-treat. Most infestations need more than one visit.

You should get a written service report listing the products used (with EPA registration numbers), where they went and any re-entry instructions. The National Pesticide Information Center (NPIC) suggests keeping a record of each product's name, registration number, formulation (gel, spray, dust) and where it was applied, plus the technician's name and the visit dates.

What a routine quarterly visit actually is

A first visit for an active problem and a routine "general pest" visit are very different jobs. Technicians describe a standard quarterly service on a home with no active problem as: knocking down webs on eaves, windows and outbuildings, spreading insecticide granules in a band around the foundation, and spraying a liquid residual on the lower foundation and around doors and windows. It often takes 10 to 20 minutes. That's useful as prevention in the South and Southwest, where ants, roaches, spiders and scorpions keep coming in from outside. It does little for a problem that lives indoors, like German cockroaches, bed bugs or mice in the walls.

How to choose a pest control company

Check the license. Every state requires commercial applicators to be certified through its pesticide regulatory agency (usually the state department of agriculture). Most states have an online lookup. NPIC also suggests checking that the license covers the right category: structural pest control, and wood-destroying organisms for termite work. Ask whether the person treating your home is licensed or working under a licensed supervisor, and whether the company carries liability insurance.

Get an inspection before a price. A real quote comes after someone has looked. A big number over the phone, or a "today only" discount, is a red flag.

Ask these questions:

What pest do you think this is, and how sure are you?
What products will you use, and where? Can I see the labels?
How many visits are included, and what happens if they come back?
What do I need to do: prep, sanitation, repairs?
Is this a one-time service, or are you signing me up for a contract? Can I cancel?

Read the guarantee. "Guaranteed" can mean free re-treatment between scheduled visits, a refund, or (for termites) repair coverage. Get it in writing, with the conditions.

Compare two or three companies. Check reviews for patterns (no-shows, upselling, recurring problems) rather than star averages. Membership in a state pest control association or the National Pest Management Association is a plus but not a guarantee.

Be wary of: door-to-door sales crews pushing multi-year contracts, anyone who won't name the products, treatment that is only "fogging", and companies that never mention sealing or sanitation.

Quick checklist

Green flag	Red flag
Inspects before quoting	Price over the phone or by text
Names the pest and explains why it's there	"We treat for everything"
Gives product names and EPA Reg. Nos.	Won't name products
Includes follow-up visits in writing	Cheap first visit, paid follow-ups
Talks about sealing, moisture, sanitation	Spray only, every time
Clear cancellation terms	Auto-renewing 1–2 year contract, cancel fee
Local references, years in business	Door-to-door, "your neighbors just signed up"

Non-toxic and low-toxicity pest control

"Green" or "eco" pest control usually means IPM with a preference for exclusion, traps, baits in enclosed stations and lower-toxicity products like boric acid, diatomaceous earth, insect growth regulators and botanical oils. It can work very well for cockroaches, ants, mice and silverfish. It is not a magic category: some "natural" products are minimum-risk pesticides exempt from EPA registration and have little efficacy data. Ask what they'll actually do differently.

About fogging

Total-release foggers and space fogging look impressive but are rarely the right tool indoors. The droplets settle on open surfaces while cockroaches, bed bugs and ants hide in cracks, and repellent fogs can scatter insects deeper into walls. Foggers also cause real harm: a CDC review found 466 fogger-related illnesses and injuries in just eight states from 2001 to 2006, 85 percent of them in homes, mostly from people not getting out in time, going back in too early or using too many cans. Explosions from pilot lights and other ignition sources were a factor in about 4 percent of cases. A professional who leads with fogging for an indoor infestation is worth questioning.

Before and after a treatment

Bedroom prepared for treatment: bed taken apart, mattress against the wall, belongings bagged

Before: follow the company's prep sheet. Typically: clear under sinks and the edges of floors, put food and dishes away, vacuum, move pets' bowls, cover fish tanks and turn off their pumps, and arrange for kids and pets to be out during the treatment if they'll be spraying indoors.

After:

Stay out until sprays have dried or for the time on the label (often 1 to 4 hours).
Don't wipe or mop treated baseboards and cracks for a couple of weeks; wipe counters and tables where food goes.
Don't spray your own products over gel baits; it contaminates the bait.
Expect to see more insects for a few days after a cockroach or ant treatment as they are flushed out and die.
Keep the service report.
Don't add your own sprays between visits unless the company agrees. Technicians on r/pestcontrol say homeowners who "help" with store-bought sprays often push roaches and ants around and make the problem harder to fix. If pests come back, call for the free re-treatment your guarantee includes.

What people who've hired pest control say

Threads in r/pestcontrol, r/homeowners and r/HomeImprovement keep coming back to the same points, many of them from technicians:

The sales model causes most of the complaints, not the chemicals. Typical story: a door-to-door rep offers a "$99 today" first visit, then $149 to $160 a quarter on a one- or two-year contract that costs around $200 to cancel. Several people said they were told a neighbor had just signed up, which turned out to be false. Under the FTC Cooling-Off Rule you generally have three business days to cancel a door-to-door sale of $25 or more in writing.
Small local companies get recommended over big brands again and again, including by technicians at the big brands. Former techs at national firms describe production pay (paid per stop) and new hires being sent on first visits, which leads to rushed work.
You're mostly paying for the technician's time and knowledge. Pros and their own customers point out that the products are largely the same ones sold online to homeowners. The value is in correct identification, placement and follow-up.
One visit rarely fixes an indoor problem. For German cockroaches, technicians usually expect at least three visits. A company that offers a single "treatment" for a roach problem, or diagnoses it from a text message, gets a lot of skepticism.
Check the work before signing off on big jobs. In one widely shared thread, a homeowner was charged about $8,000 for attic rodent cleanup and insulation, and vent screening listed on the contract was never done. The advice: have them walk you through what was done before you pay.
Plenty of homeowners don't need a contract at all. A few spiders, ants or a stray mouse are normal. People who cancelled routine service and did basic prevention themselves often reported no difference.

DIY or professional?

Many problems (a few ants, the odd mouse, silverfish, fruit flies) are well within DIY range with the right method. Termites, bed bugs, heavy German cockroach infestations, rats in walls and anything in a multi-unit building usually need a professional.
