- Termite swarm indoors
- Heavy rodent problem
- Roaches overrunning kitchen
Within a day or two

- Mosquito or tick program
- Termite check for a sale
The full list, in the guide's words
Safety first: A sting or bite followed by trouble breathing, swelling of the face, tongue or throat, dizziness, or hives spreading across the body is an emergency. Call 911 right away, and use an epinephrine auto-injector if one is prescribed. A bat in a room where someone slept, or a bite or scratch from a bat, raccoon, skunk or other wild mammal, can carry a rabies risk. Wash the wound with soap and water and call a doctor or your local health department right away.
Emergency: call now
- An aggressive stinging-insect nest by a doorway, or where an allergic person, an older adult, an infant or a pet has to walk
- A wild animal loose inside the living space (raccoon, squirrel, bat, skunk)
- A live termite swarm coming out of an indoor wall
- A sudden heavy rodent infestation in a home with an infant, an older adult or someone with a weakened immune system
- A cockroach infestation overrunning the kitchen
Within a day or two
- Confirmed bed bugs. It is urgent for you, but treatment needs prep, so it is never same-hour
- The first clear signs of rodents: droppings, gnawing, scratching in the walls
- A wasp nest in a low-traffic spot, carpenter ants or termites with no active indoor swarm, or ants or roaches that are spreading
Can wait: schedule it
- Recurring protection plans, one-time treatments, and mosquito and tick programs
- Termite inspections for a home sale, and all quotes
This is general guidance, not a diagnosis. If anyone is in danger, call 911 first.
What's on a pest control quote
InspectionAsk: free, flat fee or credited?
Whether the first visit is free, a flat fee, or credited toward the treatment.
Initial treatmentAsk: what does the first visit clear?
A heavier first service meant to clear an active problem.
Recurring planAsk: schedule, pests, extra charges?
The visit schedule, what pests are covered, whether inside and outside are both included, and what triggers an extra charge.
Exclusion & repairsAsk: is sealing entry points separate?
Sealing entry points for rodents and wildlife. Often a separate line from trapping and baiting.
Termite protectionAsk: re-treatment only, or damage too?
A one-time treatment or a bond or warranty that may need yearly renewal. Know whether it covers re-treatment only or damage repair too.
Re-service & guaranteeAsk: free return visits, how long?

What a good estimate spells out9 things to look for
- The contractor's legal name, license number if one applies, and contact details, plus your name and address.
- What work is included, and what is not.
- The brand, model and size of major equipment and materials, not just standard or builder grade.
- Who pulls the permit and who pays for it and for inspections.
- Cleanup, and what happens to the old materials.
- A start date and a realistic finish date, and what happens if the schedule slips.
- Warranty terms: what is covered, for how long and who honors it.
- When and how you pay, tied to finished stages of work rather than just dates.
- How changes are handled: a written price for any change before the work happens.

Red flags
4 of 12Plan with no schedule or terms
Ask about renewal and cancelling.
Free inspection, urgent upsell
Always urgent, always to sign today.
Fogging as the first answer
The same heavy spray for every pest.
Product not named
Ask which product and where it goes.
8 more red flags
Termite treatment with no written warranty or bond terms.
Pressure to sign today, or a price that is only good right now.
A fair quote is still fair tomorrow.
No written quote, or a quote that is a single total with no detail about what is included.
A large payment up front, or a request for cash only.
Some states limit how much a contractor can ask for before work starts.
A license number that does not check out.
Where your state licenses this trade, look the number up yourself on the state licensing board's site.
No proof of insurance.
Ask for a certificate sent to you directly by the insurer or the agent.
A price far below every other quote, followed by extras once the work has started.
Someone who knocks on your door uninvited, or who will not give recent local references.
Where homeowners say it goes wrong
- They're grossed out or scared (roaches, rodents, a bat in the bedroom) and want someone NOW
- They're worried about pesticide safety around children, pets, and food
- They feel embarrassed (especially with bed bugs or roaches) and want discretion
- They don't trust whether they need a one-time spray or a real plan, and fear being upsold into a contract
- They got wildly different quotes and can't tell who's legitimate/licensed
- A termite or WDI issue is holding up a home sale and they're on a deadline
- A previous company sprayed once and 'the bugs came right back' so they doubt anything works
- For bed bugs/termites they're overwhelmed by the prep, cost, and multi-visit process
Ask every pest control company
What exactly will you apply and where, and what do I do about kids, pets and food before and after?
What does the plan cover (which pests, inside and out), how often are the visits, and what costs extra?
What do you do to keep them from coming back (sealing entry points, moisture and clutter fixes), and what is your re-service policy?
2 more questions
Are you licensed where this work requires it, and insured? Can I see the license number and a certificate of insurance sent to me by your insurer?
What exactly does the warranty cover, for how long, and who honors it (you, the manufacturer, or both)? Will you put it in writing?
Permits
This work rarely needs a permit, although exceptions exist when it touches structure, electrical, plumbing or gas.
Pest control is not a building-permit job, but applying pesticides for hire is regulated. In most states the company and its applicators need a state license, and termite treatments and fumigation are more tightly controlled. Ask for the license number and the treatment plan.
- Your building department decides what applies at your address. Rules differ by city and county, and HOA, condo or historic-district rules can add more.
- Ask who pulls the permit. Normally the licensed contractor does and the price includes it. If a contractor asks you to pull it in your own name, ask why: it can shift responsibility for the work to you.
- If you are unsure, call your local building department before you sign. Unpermitted work can cause problems with insurance and when you sell.
Words you'll see
IPM (Integrated Pest Management)
An approach that combines prevention, monitoring and targeted treatment instead of routine spraying. Ask how a provider uses it.

Paying for it
Before you finance anything6 basics, then the financing guide
Most home projects can be paid in cash or financed. A few basics before you sign anything:
- Ask for the cash price and the financed price in writing, for the same scope of work. They can differ, because a financing fee (sometimes called a dealer fee) may be built into the financed price.
- Compare the total you will pay over the whole loan, not just the monthly payment.
- Read the fine print on same-as-cash and zero-interest offers, especially what happens if the balance is not paid in full by the end of the promotional period.
- PACE financing is repaid through your property tax bill and can place a lien on your home. Read the terms closely, and consider asking your mortgage servicer how it is treated, before you agree.
- Utility and state programs sometimes offer low-rate loans for efficiency work. Check yours before accepting the contractor's offer.
- Take loan paperwork home and read it. A sign-it-today loan is a reason to slow down.

Types, pros, cons and lifespan6 notes, each with its source
- Integrated pest management: IPM monitors and identifies the pest first, prevents problems at the source, and then picks effective, lower-risk controls such as traps before targeted pesticides. Broadcast spraying of non-specific pesticides is a last resort.EPA: Integrated Pest Management (IPM) Principles (opens in a new tab)
- Liquid soil barrier for termites: The most common treatment is a soil-applied barrier with a termiticide labeled for that use. If done improperly it can contaminate the home and nearby drinking water wells and will not protect against termites, so hire a licensed, trained professional.EPA: Termites, How to Identify and Control Them (opens in a new tab)
- Termite baits: Bait systems use cellulose baits with a slow-acting insecticide and were introduced to reduce overall insecticide use.EPA: Termites, How to Identify and Control Them (opens in a new tab)
- Physical barriers: Steel mesh and sands of particular sizes work as barriers against termites, and are typically built in during construction. Borates are commonly sprayed on wood during new construction.EPA: Termites, How to Identify and Control Them (opens in a new tab)
- Traps and bait stations: These can control some pests with low exposure risk if kept out of reach of children and pets and used by the label.EPA: Smart Pest Control to Protect Your Health (opens in a new tab)
- Which termite: The common type in most of the U.S. is the native subterranean termite. Drywood and invasive Formosan termites are others, and control techniques differ for each, so identify the type first.EPA: Termites, How to Identify and Control Them (opens in a new tab)
