Pest Control & Termite Extermination Point-Earning｜The Real Win Is Choosing a Contractor Whose Workmanship, Chemicals, and Warranty Are Solid for Thorough Extermination and Recurrence Prevention — Routing Cashback on a Bulk Quote Rides on Top

Q: If pests appear in a rental property, should I call a contractor myself or contact the landlord/property manager first?

In a rental, contact the landlord or property manager before calling a contractor yourself. The reasons: ① if the cause is a structural issue (termite pathways, rat entry points in the building fabric, etc.), the lessor may bear the extermination cost; ② arranging treatment or work without permission can cause disputes over restoring the property to its original condition or violate the lease; ③ in shared buildings, pests can affect other units too, so building-wide treatment may be necessary. Generally, whether the cost falls on the tenant (e.g., a cockroach infestation caused by insufficient cleaning) or the building owner depends on the root cause. Contact the property manager first to report the situation, confirm their response plan and cost allocation, then proceed. If you end up paying out of pocket, routing through Pointnavi for a bulk quote will at least get you some cashback. Also check your lease for any pest-control clauses.

Q: I had it exterminated, but the same pest came back. Should I ask the previous contractor or a different one?

First confirm whether it's within the warranty period of the previous work. If it's within the warranty and "free re-treatment on recurrence" is stated, asking the previous contractor for free handling is the default (have the warranty document and applicable conditions ready before contacting them). Conversely, if the warranty period has passed or it's outside the warranty's scope (e.g., only inspection was free), getting fresh estimates from multiple companies to compare is reasonable. Recurrence means the previous method or work range didn't suit the situation, or the entry-route blocking was insufficient. Tell the next contractor "what work was done last time and when it recurred," and have them propose something that accounts for the recurrence cause (entry route, chemical, range). To avoid repeating the same mistake, check the warranty contents even more carefully than last time.

Point-earning with pest control — pick a contractor on "thorough extermination and recurrence prevention," then take the quote-routing cashback as a bonus

When you hire a contractor for pest control — termites, cockroaches, wasps, rats — a bulk-quote or application is sometimes a point-site completion offer. Termite extermination and under-floor treatment in particular can get expensive, and comparing several contractors alone can make a difference of tens of thousands of yen. "Since I'm getting quotes anyway, I might as well route for cashback" is a perfectly sensible idea.

But in this category, points are thoroughly secondary. Pests differ wildly by type in how damage progresses, how dangerous they are, and how urgent the response needs to be. If a contractor chosen "because they're cheap or have a high cashback rate" can't achieve thorough extermination, you'll be paying twice when it recurs. The four axes for choosing a contractor are: ① does the contractor do a proper on-site inspection? ② Is the workmanship and chemicals appropriate for the pest type and current situation? ③ What exactly does the warranty cover, including free re-treatment on recurrence? ④ How safe are the chemicals (for children and pets)? The routing cashback comes after all that — purely a "might as well take it" bonus. This article covers pest-type-specific considerations, contractor-selection fundamentals, reading warranties, chemical safety, and the DIY/professional line alongside the point-earning mechanics. See also house cleaning, home security, and renovation quotes.

Pest type changes the urgency, how you choose a contractor, and how much point-earning matters

"Pest control" sounds like one thing, but termites, cockroaches, wasps, and rats differ completely in the nature of the damage, how fast it spreads, and what response is needed. Identifying the pest accurately is where contractor selection starts.

Pest	Nature of damage	Urgency	Key contractor criteria
Termites	Eat wood from the inside, eroding the foundation, pillars, and flooring. The later you find them, the wider the damage spreads.	Act as soon as found	On-site under-floor inspection is essential. Compare work scope, chemicals, and warranty period across several contractors.
Cockroaches	Breed fast; cause sanitary damage and significant stress. Where the nest is changes the treatment approach.	Sooner rather than later; not a crisis	Check the treatment method (bait/spray/prevention plan) and what happens if they recur.
Wasps (giant hornets, etc.)	Stings can cause anaphylactic shock. The bigger the nest, the higher the risk during removal.	High; self-treatment is dangerous	Urgency is high. Safety and certainty beat point-earning. Verify the contractor's equipment and track record.
Rats	Gnaw food and wiring (fire risk); droppings cause sanitary problems. Sealing entry points is key.	Sooner rather than later; don't ignore	Check whether extermination and entry-point sealing are done together, and what the recurrence policy is.

For high-urgency, high-danger situations like a giant-hornet nest, skip the point-earning for now and call a contractor immediately. Routing cashback is not worth risking your life. Termite damage is hard to see and easy to miss — if you notice flying ants indoors, creaking floors, or soft-feeling pillars, request an on-site inspection sooner rather than later. Home center guide also covers preventive supplies.

White ants (termites) are especially scary because they "progress where you can't see," so knowing the early-detection signs lets you minimize damage. Typical signs are: ① winged ants swarming indoors from spring into early summer (especially the bathroom, entrance, window areas), ② mud "shelter tubes" (ant roads) running along the foundation or post bases, ③ floors that feel spongy or creak, ④ a light hollow sound when you tap a post or threshold, ⑤ small holes or wood dust on tatami or woodwork. The moment you notice such signs, rather than judging on your own and scattering store-bought chemicals, requesting an on-site survey to accurately grasp the damage range ends up saving cost and effort. An "early survey" before damage spreads leads to reliable extermination and saving money.

The heart of contractor selection — on-site inspection quotes, not phone quotes, compared across several contractors

The single most important thing when choosing a pest-control contractor is getting a quote that comes after an actual on-site inspection. Ballpark estimates over the phone or via a web form are prone to generating extra costs after the work begins, and the right scope and chemicals can't be decided without seeing the property.

First, check whether the on-site inspection is free: Some contractors charge for the inspection; others don't. If you're contacting multiple contractors, ask upfront whether the on-site visit is free of charge.
Get quotes from at least three contractors: For termite extermination in particular, the work scope, chemicals, and methods vary considerably between contractors. Wide price differences for the same property are common, so multi-contractor comparison matters both for cost and for certainty.
Confirm the work scope and method in detail: "Soil treatment, wood treatment, or both?" "The entire under-floor area, or just the affected sections?" — cheaper quotes sometimes cover a limited scope. Check that the written quote specifies the exact work to be done.
Be wary of quotes that are extremely cheap: Some contractors quote low to get in the door, then push additional work. Always compare workmanship and total cost.

If the bulk-quote service is a point-site offer, you can run multi-contractor comparisons while also capturing the routing cashback. Check the offer and earning condition (quote only / request / work required) on Pointnavi before applying. Paying high contractor fees with a tap-payment cashback method adds another layer of reward on top.

What to watch for in choosing a contractor is "inspection sales" that use a "free inspection" as the entry point, stir up anxiety, and press you to sign on the spot. There are cases where someone visits saying "we'll look under your floor for free," then excessively plays up a sense of crisis like "your house will collapse if left like this" to force an immediate decision on expensive work. Even if there really is damage, the iron rule is to not sign on the spot and to decide only after comparing on-site survey estimates from multiple companies. Even if shown inspection photos, calmly confirm whether they're of your home and whether it's truly urgent. If you do sign on the spot, door-to-door sales can sometimes be canceled via cooling-off within a set period. For preparing against such housing-related contract troubles, our household-contracts roundup is also helpful.

Reading the warranty — recurrence-free re-treatment, duration, and conditions vary widely between contractors

Even when a contractor advertises a "5-year warranty," the real value depends entirely on the details. Taking recurrence as a given and checking the warranty's applicability conditions is the crux of genuine extermination certainty.

Check item	Good example	Watch-out example
Response on recurrence	Free re-treatment	"Inspection only is free; re-treatment is charged"
Warranty period	5–10 years (longer is reassuring for termites)	1 year only, or not stated
Conditions for coverage	No mandatory inspections; no special conditions	Requires periodic inspections; floor renovation required, etc.
Scope stated explicitly	All treated areas covered	Only part of the treated area; scope not specified

For termite prevention, contractors affiliated with the Japan Termite Control Association meet a certain standard (membership is a useful data point, but don't rely on it alone — always check the work scope and warranty as well). The most important thing to check is whether the written quote explicitly states "free re-treatment if termites recur." Always obtain the warranty certificate, and confirm the conditions before work begins.

Chemical safety and post-treatment precautions — households with children or pets must ask in advance

Pest-control chemicals vary widely in type, and safety profiles and post-treatment precautions differ by contractor and product. Households with young children or pets can ease a lot of worry by asking the right questions beforehand.

Ask for the chemical type and its safety data: You can ask the contractor: "What chemicals will you use? Can I see the Safety Data Sheet (SDS)?" A trustworthy contractor will explain clearly.
Check whether you can stay home and how long to ventilate: Under-floor treatment alone often allows you to stay home, but if there's indoor spraying involved you may need to be out for several hours to half a day. Confirm before the work date.
Pets need specific attention: Cats, small dogs, fish, and birds can be sensitive to certain chemicals. Get explicit instructions from the contractor on relocating pets and covering fish tanks before and after treatment.
Allergies or chemical sensitivity in the household: Disclose this upfront. Some contractors can accommodate low-volatility or plant-based alternatives.

⚠️

Even a contractor that emphasizes "safe, odor-free" may still require ventilation or a brief period away from home after treatment. Tell the contractor "we have a child aged X / we have a cat" before the job, and confirm the specific steps they'll take. To avoid "nobody told me that" after the fact, get the chemicals used and post-treatment precautions in writing.

The DIY/professional line — "prevention and light treatment you can do yourself" vs. "situations where you need a contractor"

Not every pest problem requires a contractor. But reckless DIY can also spread damage or create danger. Having a clear sense of "should I handle this or call someone?" protects you on both cost and safety fronts.

Where DIY works: Cockroach bait traps (early-stage, small numbers); rat repellents to deter light incursions; off-the-shelf ant barrier products around entrances. This only applies when damage is minor and breeding hasn't spread yet.
When you need a contractor: Termite damage (or multiple flying ants found indoors); a wasp nest (especially giant hornets or a large nest); rat entry points that go into walls or the attic; a large cockroach infestation or one where the breeding site can't be found.
Prevention has the best ROI: Termite preventive treatment is generally recommended every 5–7 years. Remediation after damage appears typically costs far more, so preventive treatment while there's "zero damage now" is smarter in the long run.
Know the limits of off-the-shelf products: Even fast-acting retail insecticides can't eliminate a nest or seal entry points. If problems keep recurring, consider bringing in a professional.

Prevention and periodic inspection typically cost far less than a first-time extermination. Combining plumbing renovation and housekeeping services for a planned approach to home maintenance is worth considering.

In the end, the most cost-effective pest measure is "prevention before damage appears." Extermination after damage worsens tends to widen the work range and inflate both cost and effort, whereas preventive treatment and periodic inspection often take a relatively light load. Periodic termite prevention, everyday efforts to block cockroach and rat entry routes, managing the under-floor and water areas so moisture doesn't build up — building such "maintenance that keeps damage at zero" into your home plan lets you avoid both sudden large expenses and the stress of recurrence. When requesting inspection or work for prevention too, you can take referral rewards as a bonus, but the axis for choosing is always "whether it's a contractor that can reliably prevent."

How pest-control point-earning works — mechanics and step-by-step

Lock in your contractor-selection criteria (on-site inspection, workmanship, warranty, chemical safety), then stack the routing cashback and payment cashback as a "bonus on top." That's the correct sequence for pest-control point-earning. The earning condition differs by offer (quote request only / work required). Check on Pointnavi before applying.

① Identify the pest, assess the damage and urgencyThe right approach differs completely for termites, wasps, cockroaches, and rats. In urgent cases (a giant-hornet nest, etc.), safety beats point-earning.
② Check offers and earning conditions on the point siteIf the bulk-quote service is an offer, route through Pointnavi before applying. Confirm whether it's "quote-only earns" or "work required" before submitting.
③ Request on-site inspection quotes from 3+ contractorsCompare on-site-inspection quotes, not phone estimates. Line up work scope, methods, chemicals, and warranty details for a fair comparison. renovation quotes guide.
④ Verify warranty content and chemical safety before choosingConfirm "free re-treatment on recurrence" is stated in writing, and confirm chemical safety for children and pets before signing.
⑤ Pay the contractor fee with a cashback payment methodHigh-cost work like termite extermination benefits from a cashback payment method on top. tap-payment guide.
⑥ Consolidate earned points and use them before they expirePool points from routing and payment into your main ecosystem. expiry-prevention guide.

💡

The most common way to miss out in pest-control point-earning is forgetting to route before applying. If you go directly to the bulk-quote service, you earn zero. Instead of bookmarking the service directly, make it a habit to search via Pointnavi every time. Also remember that "quote only earns" vs. "work required" are very different — always check the condition before you apply.

Mini glossary — key terms for pest control without confusion

Knowing the vocabulary around quotes, warranties, and chemicals is often enough to avoid unexpected extra costs and recurrence. Run through these before contacting a contractor.

Term	Meaning	Watch out for
On-site inspection quote	A formal quote issued after visiting the property in person	Phone-only estimates are prone to generating extra costs later
Bulk-quote service	A service that sends your request to multiple contractors at once	Check the earning condition (quote only vs. work required) before routing
Recurrence warranty	A warranty that covers free re-treatment if pests return	Conditions like "inspection only is free" must be verified in writing
Soil treatment / wood treatment	The main methods used for termite prevention	Cost varies significantly depending on whether the full area or only affected sections are treated
SDS (Safety Data Sheet)	A document listing a chemical's ingredients and safety information	Households with children or pets should always ask to see it
Preventive treatment	Treatment applied before any damage has occurred	Typically costs less than remediation after damage appears

With these terms in hand, you can evaluate "does this contractor offer thorough extermination and recurrence prevention?" before you even think about price or cashback. The right sequence: compare on-site inspection quotes from multiple contractors, confirm the recurrence warranty and chemical safety, then take the bulk-quote routing cashback as a bonus. For high-urgency, high-danger situations like wasp nests, safety always comes first. Check offers on Pointnavi.

FAQ

How often should termite treatment be done?

The effective lifespan of preventive treatment is generally targeted at 5–7 years, and re-treatment and periodic inspection on that cycle are recommended (varies by chemical and method). Preventive treatment with zero current damage is usually cheaper than remediation after damage appears. Check how long it has been since your last treatment and what the warranty from that time states, then consult a contractor.

Can you trust a contractor's "warranty included" claim? What exactly should I check on the warranty document?

How good the warranty is depends entirely on what it says. Check: ① whether recurrence triggers "free re-treatment" (sometimes only inspection is free; re-treatment is charged); ② the warranty period (5+ years is common for termites); ③ the conditions for coverage (does it require periodic paid inspections?); ④ the scope (does it cover all treated areas?). Confirm everything in writing before signing, and always take the warranty certificate with you.

Can I remove a wasp nest myself?

Off-the-shelf aerosol insecticides can work in limited cases — small nests at low heights, or small honey-bee or paper-wasp colonies. Giant hornets, large nests, or nests inside walls or attics pose a serious risk of multiple stings without professional protective equipment. A wasp sting triggering anaphylactic shock can be fatal. If there is any doubt, call a contractor. In that case, deprioritize point-earning entirely and focus on safety and speed.

For an offer that requires work, do I earn nothing if I only get a quote?

Correct. Offers split into "earning completes on quote/request alone" and "work must be placed." Always check the earning condition on the Pointnavi offer page before applying. For work-required offers, a quote alone earns nothing. Also: if after routing you navigate away from the point site to go directly to the contractor's website, the tracking cookie breaks and you fall out of scope. Stay in the same browser session all the way through to completing the application.

What should I do on the day of treatment when I have children or pets?

Tell the contractor in advance "we have a child aged X / we have a cat," and confirm specifically which chemicals they'll use, ventilation time needed after treatment, and whether you need to vacate. Under-floor-only treatment usually lets you stay home, but indoor spraying may require you to leave for several hours to half a day. Fish and birds can be particularly sensitive to certain chemicals — ask the contractor for specific instructions about moving them and covering tanks. Get post-treatment precautions in writing, not just verbally.

Is it rude to contact multiple contractors for quotes? How do I turn one down?

Contacting multiple contractors for quotes is something they fully expect — it's not rude. The polite approach is to say upfront "I'm comparing quotes from several contractors." To decline, a simple phone call or email saying "I've decided to go with another contractor this time" is enough. There's no need to explain in detail. Using a bulk-quote service lets you notify multiple contractors in one step, which saves time as well.

How much does pest control typically cost, and how can I avoid overcharges?

Costs vary widely by pest type, extent of damage, property size, and method — there is no single reliable figure. Termite extermination depends on floor area and scope; wasp nest removal depends on nest size, location, and species; rat control depends on whether entry-point sealing is included. For that reason, "comparing on-site inspection quotes from multiple contractors to find the right price for your home" is far more reliable than trusting any published figure. Key ways to avoid overcharges: ① always get a formal written quote based on an actual on-site inspection; ② compare at least three contractors on the same work scope, method, chemicals, and warranty; ③ be wary of contractors who pressure you to sign on the spot with "discount if you decide today" — don't sign under pressure; ④ confirm the total cost and whether any extra charges could arise before work begins; ⑤ be alert to extremely cheap quotes that may narrow the work scope and then push add-ons. In Japan, cooling-off rights may apply to door-to-door sales contracts within a certain period. Using a bulk-quote service via Pointnavi lets you compare and earn cashback at the same time.

If pests appear in a rental property, should I call a contractor myself or contact the landlord/property manager first?

In a rental, contact the landlord or property manager before calling a contractor yourself. The reasons: ① if the cause is a structural issue (termite pathways, rat entry points in the building fabric, etc.), the lessor may bear the extermination cost; ② arranging treatment or work without permission can cause disputes over restoring the property to its original condition or violate the lease; ③ in shared buildings, pests can affect other units too, so building-wide treatment may be necessary. Generally, whether the cost falls on the tenant (e.g., a cockroach infestation caused by insufficient cleaning) or the building owner depends on the root cause. Contact the property manager first to report the situation, confirm their response plan and cost allocation, then proceed. If you end up paying out of pocket, routing through Pointnavi for a bulk quote will at least get you some cashback. Also check your lease for any pest-control clauses.

I had it exterminated, but the same pest came back. Should I ask the previous contractor or a different one?

First confirm whether it's within the warranty period of the previous work. If it's within the warranty and "free re-treatment on recurrence" is stated, asking the previous contractor for free handling is the default (have the warranty document and applicable conditions ready before contacting them). Conversely, if the warranty period has passed or it's outside the warranty's scope (e.g., only inspection was free), getting fresh estimates from multiple companies to compare is reasonable. Recurrence means the previous method or work range didn't suit the situation, or the entry-route blocking was insufficient. Tell the next contractor "what work was done last time and when it recurred," and have them propose something that accounts for the recurrence cause (entry route, chemical, range). To avoid repeating the same mistake, check the warranty contents even more carefully than last time.

Should I sign up for the "periodic inspection / prevention plan" the contractor recommends?

Pests (especially termites) are cost-effective to prevent, so a periodic inspection / prevention plan itself is a reasonable option. But there are points to confirm before signing: ① whether the inspection/prevention frequency and content suit your home's situation (age, whether it's wood-frame, how damp it is), ② the fee, contract term, and mid-term cancellation conditions, ③ whether it becomes a form of "inspection is free but you're urged to add work every time," ④ if bundled with a warranty, whether "receiving periodic inspection" is made mandatory in the warranty's applicable conditions. The prevention idea is sound, but some contractors try to get you to sign with excessive frequency or unnecessary options. "Prevention matters" and "signing as told" are different things. It's safer to scrutinize the plan contents and compare prevention plans from multiple companies before deciding. If you feel it's unnecessary you may decline, and even then, taking it home to think it over lets you judge more calmly.
