Questions to Ask Pest Control
These are the questions to ask a pest control company before you agree to treatment, whether it is mice in the attic, ants in the kitchen or something nobody has identified yet. They work just as well as questions to ask an exterminator who is already standing in your hallway with a quote. The list runs in the order the job does: the first call, the inspection, the treatment and its safety around children and pets, the price and contract, and what happens afterwards.

The questions
Each question, and why to ask it
First call
Can you send someone to inspect before you quote?
Why ask it
A price given over the phone is a price for a standard treatment, because all the company has to go on is your description. Until someone has looked for the entry route and the nest, the plan can only be to treat the rooms you mentioned.
Is the inspection free, and if you charge for it, does the fee come off the price of treatment?
Why ask it
Both arrangements are normal, so the point is to know which one you are in before someone is at the door. A free inspection is paid for by the jobs it sells, which is worth remembering when the findings arrive with a same-day offer.
Are you licensed here, and will the technician who comes be certified?
Why ask it
Rules for applying pesticides differ by country and state, and in many places the licence belongs to a person as well as to a company, so ask how it works where you live. Take the number and look it up with the body that issued it. The person who quotes is often not the person who applies, and it is the applicator's certification that matters.
What insurance do you carry, and what happens if the treatment damages something or makes someone unwell?
Why ask it
Stained flooring, a tank of dead fish and a technician's foot through the bedroom ceiling are all things that somebody has to pay for. A certificate of insurance with current dates is a normal thing to be sent, and your own home insurer can tell you how a claim would work if the company's cover fell short.
How often do you deal with this particular pest in homes like mine?
Why ask it
A firm that mostly does wasps and ants may take on bed bugs or a squirrel in the roof without doing either very often. Listen for detail: the usual hiding places, how many visits the job normally takes, the way it tends to go wrong.
Do your own staff do the work, or is it subcontracted?
Why ask it
Subcontracting is common and not automatically a problem, but it changes who is insured, who honours the guarantee and who you call when something goes wrong. Get the answer in writing if a national brand is quoting for local work.
Will the same technician come each time?
Why ask it
Someone who has already seen your crawl space knows which bait station was untouched and which gap was sealed last month. With a different face on every visit, that knowledge lives only in the notes, which makes the notes worth seeing.
How soon can you come, and is there a surcharge for an urgent or out-of-hours visit?
Why ask it
A wasp nest above the back door and a mouse heard once in the garage do not need the same speed. Hear the price of urgency before you request it, and get told what you can safely do while you wait, such as keeping a room shut or food sealed.
Inspection
What do you think it is, and what are you basing that on?
Why ask it
Ask what evidence they found: droppings, gnaw marks, shed skins, live insects, a smear along a joist. Treatment differs sharply between species that look alike, so an answer that names the pest without pointing at anything physical is a guess with a price attached.
How big is the problem, and how long do you think it has been here?
Why ask it
Fresh droppings beside old ones, the size of a nest and the spread across rooms all tell a technician something about age and scale. The answer sets your expectations for how many visits are reasonable, and it is useful to have in writing if you rent or have just bought.
Where do you think they are getting in?
Why ask it
Treatment deals with the animals already inside; closing the route deals with the next ones. If nobody has looked at the roofline, the holes around pipework or the gap under the door, the quote is for repeat visits.
Which parts of the property did you check, and which could you not get to?
Why ask it
Attics, crawl spaces, the void behind the kitchen units and the back of the garage are where the evidence usually is and where a rushed inspection does not go. An honest list of what was not reached tells you how much of the diagnosis is inference.
What is drawing them here in the first place?
Why ask it
Pests stay for food, water or shelter, and there is normally a specific source: a dripping trap under the sink, pet food left down overnight, a compost heap against the wall. Treating without naming it leaves the invitation open.
Is treatment actually needed here, or is this something I could deal with myself?
Why ask it
A handful of ants, one wasp indoors or a single mouse often needs sealing and cleaning rather than a chemical programme. An honest firm will say so, and the willingness to talk you out of a job is the strongest recommendation any of them can offer.
Have they done any damage that someone else should look at?
Why ask it
Rodents chew cable insulation and pipes, and some insects work through timber where nobody sees it. A pest technician can point at the damage but is usually not the person to assess wiring or structure, so ask who they would call.
Will you put what you found in writing, with photographs?
Why ask it
A short report with pictures lets you compare one company's diagnosis with another's instead of comparing prices for unknown jobs. Landlords, managing agents and insurers tend to ask for exactly this document, and it is far easier to get on the day than a month later.
What happens if the source turns out to be next door or in a shared wall?
Why ask it
In a terrace, a duplex or an apartment building, treating one home can send the problem through the wall and bring it back a month later. Some firms will speak to the neighbour or the management company themselves, and who pays for work on a shared wall depends on your lease or the building's rules, so read those too.
Treatment
What are the options for treating this, and why are you recommending that one?
Why ask it
For most pests there is more than one route: traps, baits, dusts, sprays, heat, or sealing the building and waiting. Hearing the alternatives, with what each costs in money and disruption, shows whether the recommendation was chosen for your house or is simply what the van carries.
Could this be done with less pesticide, or none?
Why ask it
Trapping, proofing, vacuuming and heat settle some household problems on their own and cut down what has to be applied for others. If the answer is no, a good technician can explain why this pest in this spot needs a chemical, and that explanation is worth having.
Exactly what product will you apply, and can I see the label and safety data sheet?
Why ask it
The active ingredient is the useful answer, not a brand name or a phrase like professional grade. A registered product should come with a label and a safety data sheet, and a technician who can produce neither may not know what is in the van.
Which rooms and surfaces will you treat, and which will you leave alone?
Why ask it
Kitchen counters, cots and bedding are the places to name one by one, before the visit rather than while it is happening. If the plan is to spray along every wall in the house whatever the pest, have the technician explain what that adds over treating the spots where the pest actually is.
What do I need to do before you arrive?
Why ask it
Preparation is often substantial: emptying kitchen cupboards, stripping beds, moving furniture from walls, pulling up carpet edges. Skipped preparation is a common reason a treatment fails, and a common reason a company gives for not honouring its guarantee.
Do I need to be home for the visit, and how long will it take?
Why ask it
Some jobs need you there to unlock the attic hatch, shut the dog away and hear what was found; an outdoor treatment may not need you at all. If you cannot be in, settle before the day how the technician gets access and how you will be told what was done, so the report is not a card through the door.
How long do we need to be out of the house afterwards?
Why ask it
The product label says how long people and pets stay out, and the answer differs a great deal between a bait, a spray and a fumigation. Get the figure before you book, because arranging somewhere to be for an afternoon is easier than finding out on the doorstep.
Does the plan change with small children, a pregnancy or pets in the house?
Why ask it
Say out loud who lives here, including anyone with asthma, and mention the fish tank, the bird and the reptile as well as the dog. A plan that looks the same after hearing all that has not taken it in. The technician can tell you what the label requires; for a health worry about a particular person, their own doctor is the one to check with.
If you are using bait or rodenticide, what is the risk to my dog and to wildlife?
Why ask it
Poison bait can harm an animal that eats the poisoned rodent as well as one that finds the bait, and dogs dig. The details that matter are whether the bait sits in locked, tamper-resistant boxes, where each box goes, and which product name to give the vet if your dog gets into one.
Will anything be applied outdoors, and what does that mean for the vegetable bed, the pond and the bees?
Why ask it
Perimeter sprays and granules land where children play and where pollinators feed, and some products are harmful to fish if they reach water. You want to hear what goes outside, how close to drains and flowering plants, and whether rain or the sprinkler changes the timing.
What should I do about food, dishes and worktops, and when is it safe to clean?
Why ask it
The instructions pull in two directions: wipe the surfaces where food is prepared, but leave treated edges alone so the residue keeps working. Get told exactly which is which, and how long to hold off mopping, or an ordinary weekend clean can undo the visit.
Will the treatment leave a smell, a stain or a visible residue?
Why ask it
Dusts can show as a pale line along a skirting board, some sprays mark dark fabric or stone, and a few have an odour that lingers for days. Better to hear it now than to find it on a new carpet, and it tells you which rooms to air.
If a rodent dies under the floor or inside a wall, who finds it and who removes it?
Why ask it
Nobody raises this at the quote, and the smell can last for weeks. Retrieval may be included, charged by the hour or not offered at all, and lifting a board or cutting a panel is a bill for somebody. It is also a fair reason to prefer traps, which leave the animal where it can be found.
Price and contract
Is this a single visit or a course of treatment, and how far apart are the visits?
Why ask it
Some problems need a set series timed to the pest's life cycle, so that the second visit catches what hatched after the first; others need one visit and a check. Get the number of visits and the gaps between them as figures, because a late visit in a timed series can mean starting the count again.
What is the total cost, and what would add to it?
Why ask it
Three things commonly move the figure: a second treatment, a panel that has to come off for access, and an infestation larger than it looked. A quote that covers only the first visit makes a course of treatment look far cheaper than it is.
Is sealing the entry points included, or is that a separate quote?
Why ask it
Proofing is often priced apart from treatment, and sometimes it is handed to a different trade altogether. The quote should say who does it, which gaps are on the list and what goes into them, and whether the guarantee depends on that work being finished.
When is payment due, and do you take a deposit?
Why ask it
Paying per visit or on completion leaves the company a reason to come back, which a whole course paid up front does not. If a deposit is asked for, find out what it buys and whether it is returned if the first visit shows the job is smaller than quoted.
Can I take the written quote away and have the same price next week?
Why ask it
A fair quote survives a few days of thought and a second opinion. If the figure only holds while the technician is in your kitchen, that is a sales method, and the pest will still be there on Tuesday for whoever you choose.
Do I need a regular plan once this is dealt with, or is that optional?
Why ask it
Some properties do have steady pressure: a restaurant next door, woodland behind, an old building with a hundred gaps. Many do not, and a one-off job with a check visit is enough. The answer you are after names something about your house, not about houses in general.
Which pests does the plan cover, and which would be charged as extras?
Why ask it
General plans tend to list the common crawling insects and leave out the expensive jobs, typically termites, bed bugs and wildlife in the roof. Read the list against what you are worried about, because a plan that excludes your actual problem is only a subscription.
Am I signing a contract, and how do I get out of it?
Why ask it
Service plans often renew automatically, with the notice period for cancelling somewhere in the small print. Get the minimum term, the notice required and whether the price can rise during it. Rights to cancel something signed at your own door differ by country and state, so check what applies where you live.
Are call-backs between scheduled visits free?
Why ask it
On a quarterly plan the trouble rarely waits for the next appointment. Find out whether an extra visit costs nothing, how quickly it happens, and whether there is a limit on how many you can ask for in a year.
What does the guarantee cover, and what voids it?
Why ask it
Read the exclusions rather than the headline. Guarantees commonly lapse if you do not complete recommended repairs, if you have another company treat the property, or if the pest is deemed to have re-entered rather than survived, which is a distinction they get to make.
Afterwards
What will you leave me in writing after each visit?
Why ask it
You want the product name, the amount, the places it went and the positions of any bait stations or traps. That sheet is what a vet or a doctor would ask for if someone were unwell, and what the next technician needs if you change company.
What should I expect to see in the week after treatment?
Why ask it
With some treatments you see more activity before you see less, and without warning that looks like failure. You also want to know what would not be normal: a smell that stays, staining, a spread to new rooms, a pet behaving oddly.
At what point should I call you back rather than wait for the next visit?
Why ask it
A clear threshold prevents both nuisance calls and the more expensive habit of waiting a month while a problem grows. The useful version is something you can see, such as fresh droppings after the second visit or live insects in a room that was clear, not a feeling that things are not improving.
How will we both know it has worked?
Why ask it
Agree a test in advance: no fresh droppings on a cleaned shelf, untouched bait at two checks in a row, empty monitoring traps, no new bites. Without one, the job ends when the invoices stop and not when the pests do.
Who collects the bait stations and traps when the job is finished?
Why ask it
A bait box nobody collected can sit in a garden or an attic, still loaded, long after anyone remembers it is there. A count of what was put down, and a final visit to take it all away, settles it; if removal is left to you, get the instructions in writing.
What can I do myself to cut down the number of visits I pay for?
Why ask it
The useful answers are dull and specific: a door sweep, wire wool in a particular gap, moving the bird feeder, emptying a bin more often, clearing the wood pile off the wall. A company that has nothing to suggest here is content for you to keep needing them.
Is this likely to come back at a particular time of year?
Why ask it
Mice tend to move indoors as the weather cools, wasps build through the summer, and ants keep a calendar that varies by region. Knowing the season lets you check the seals and clear the attractions a month ahead instead of booking another treatment.
If it does return after the guarantee ends, what would you do differently?
Why ask it
The answer shows whether the firm keeps records and thinks about causes, or simply repeats the same treatment at the same price. A second infestation in the same place usually means an entry point or a food source was missed the first time.
Arranging pest control
Practical guidance for the conversation itself
Before you call anyone
- Photograph what you have seen, including droppings, damage and any insect you can catch in a jar. Identification from a photograph is far more reliable than from a description.
- Write down when and where you see activity, and at what time of day. A week of notes shows a technician where to look and at what hour.
- Note anything that has changed recently: building work next door, a new bin store, a leak, a delivery of firewood, a period away from the house.
- Check whether the problem is yours to pay for. Tenants should tell the landlord or agent first: who is responsible for pests in a rented home depends on the tenancy and on local law, so find out how it works where you live before booking anyone.
- Get two or three quotes for anything beyond a single visit, and have each of them tell you what they found rather than only what they would charge.
Species that change the situation
Termites and other structural pests
The damage is to the structure of the house, so check whether your home insurance covers it before assuming it does. Ask for a written inspection report with a diagram, ask what warranty comes with the treatment and what keeps it valid, and be wary of a quote given without anyone going under the floor or into the roof.
Bed bugs
Preparation and follow-up matter more than the product, and treatment usually takes a defined series of visits. Ask about heat treatment as an option, ask what to do with laundry and mattresses, and do not throw furniture out until you have been told to.
Rodents
Trapping and exclusion address the cause; poison alone usually does not. Ask what happens if an animal dies inside a wall or floor, and whether removal is included or charged separately.
Wasps, bees and hornets
Honey bee colonies can often be removed by a beekeeper rather than destroyed, and some firms will refer you. Ask what species they think it is before agreeing to treatment.
Protected species
Bats, and in some places certain birds and their nests, are legally protected in many countries. Anyone offering to remove them without mentioning that is a reason to stop and check with a local wildlife authority.
Get these in writing before work starts
- What was found, where, and what species it was identified as.
- The product to be used, its active ingredient, and the areas to be treated.
- Re-entry time, ventilation instructions, and any handling advice for food, bedding and pets.
- Number of visits included, the total price, and the cost of anything beyond that.
- The guarantee period with its exclusions, and the contract term with its cancellation notice.
- After each visit, a record of what was applied and where. Keep these; they matter if you sell the property or dispute the outcome.
Signs to be cautious about
- A quote given without an inspection, or a price that drops sharply when you hesitate.
- Same-day pressure, a discount that expires this afternoon, or a request for full payment in cash before work.
- An unsolicited caller who says they noticed something wrong with your property and can treat it now.
- Refusal to name the product or to show the label, or dismissal of questions about children and pets.
- Claims that a treatment is entirely safe or completely non-toxic. Every product has conditions of use, and the honest answer describes them.
- A recommendation to tent or fumigate the whole house with no explanation of why a smaller treatment would not do.
