The Best Ant Killer of 2026: Brand-by-Brand Comparison for Homeowners Who Want Ants Gone for Good
You sprayed the counter, wiped up the trail, and felt like the problem was solved — then two days later, a fresh line of ants appeared from somewhere completely different. That experience is not bad luck, and it is not your fault. It is exactly what most store-bought sprays are designed to do: kill the ants you can see, while the colony underneath stays completely intact.
Finding the best ant killer means understanding one uncomfortable truth: the ants on your counter are not the problem. According to pest control experts, killing visible ants with contact sprays can actually split colonies and make infestations worse — because the colony sends out new scouts, sometimes branching into multiple satellite nests (Source: Wirecutter, 2025). The real target is the queen, and she never comes to your kitchen.
Most homeowners focus entirely on the visible ants without ever locating the source of the infestation, which is why the problem keeps returning no matter how much product they use (Source: Knox Pest Control).
This guide covers everything you need to make one confident purchase: indoor vs. outdoor products, how to identify your ant species, a head-to-head brand comparison with cost-per-application breakdowns, and honest pet safety ratings. No more trial and error.
Why Most Ant Killers Fail (And What to Look for Instead)
The hardware store aisle is full of products that promise fast results. Most of them deliver — for about 48 hours. Understanding why they fail is the first step toward buying something that actually works.
The Surface-Kill Trap: Why Sprays Feel Like They Work
Contact sprays kill ants on impact, which is deeply satisfying in the moment. The problem is that a typical ant colony contains thousands of workers, and the ones you see foraging represent only a small fraction of the population.
Killing surface scouts signals danger back to the colony. The remaining ants reroute, the colony adapts, and new trails emerge within days. The infestation is not smaller — it may actually be spreading.
Colony Kill vs. Contact Kill: The Only Metric That Matters
A good ant killer does not aim to kill ants. It aims to collapse the colony. That distinction drives every recommendation in this guide.
Slow-acting bait products work by exploiting ant behavior: foragers carry toxic bait back to the nest, share it with other workers through a process called trophallaxis, and eventually deliver it to the queen. When the queen dies, the colony collapses. This process takes days, not minutes — and that delay is a feature, not a flaw.
Homeowners who focus only on visible ants without addressing the colony source guarantee that the problem returns (Source: Knox Pest Control). The colony is the problem. Every product decision should flow from that.
The 3 Things Any Good Ant Killer Must Do
Tip Box — The 3 Evaluation Criteria Used in This Guide
(1) Colony elimination vs. surface kill — Does the product reach and kill the queen, or only the workers you can see?
(2) Speed of effectiveness — How long before the infestation is fully resolved, not just visibly reduced?
(3) Safety profile — Is the product safe for use around pets and children in the areas where you need to apply it?
Every product reviewed in this article is evaluated against these three criteria. A product that scores well on speed but fails on colony elimination is not a good ant killer — it is a temporary fix.
Black Ant vs. Carpenter Ant: Identify Your Ant Before You Buy
Using the wrong product for the wrong ant species is one of the most common reasons DIY treatment fails. A bait that works perfectly on odorous house ants may have no effect on carpenter ants nesting in your wall studs.
How to Tell the Difference at a Glance
The size difference alone usually tells the story. Carpenter ants are large — typically 6 to 12mm — and are most often black or dark brown, sometimes with a reddish mid-section. Common black ants (including pavement ants and odorous house ants) are much smaller, usually 1.5 to 4mm, and tend to travel in dense, well-organized trails.
Another quick check: where are you seeing them? Carpenter ants near wood structures, window frames, or damp areas suggest nesting activity inside the home. Small ants streaming from a gap near the baseboards are almost certainly foragers from an outdoor colony.
| Feature | Black Ant (Common) | Carpenter Ant |
|---|---|---|
| Size | 1.5–4mm | 6–12mm |
| Color | Black, brown, or reddish-brown | Black, dark brown, or black with red mid-section |
| Where they nest | Soil, outdoor colonies, wall voids | Moist or damaged wood, wall voids, tree stumps |
| Damage potential | Low — primarily a nuisance | High — can cause structural damage to wood |
| Recommended treatment | Slow-acting liquid bait or granules | Bait plus targeted void treatment; may need inspection |
Why Carpenter Ants Require a Different Treatment Approach
Carpenter ants do not eat wood — they excavate it. That means they are not foraging for food the same way smaller ant species are, which makes standard sugar-based baits significantly less effective against them.
Carpenter ant treatment typically requires protein-based baits, direct void injection, or a combination approach. If you are seeing large black ants emerging from wall voids or wood trim, especially in a home with any moisture damage, treat this differently than a standard kitchen ant problem.
Other Common Species: Odorous House Ants, Fire Ants, and Pavement Ants
Odorous house ants are the most common culprit behind tiny ants in the kitchen — they are drawn to sweets and moisture and respond very well to liquid bait like TERRO. Fire ants require outdoor granule treatments applied to mound and perimeter areas. Pavement ants, found along foundations and driveways, respond well to perimeter granule applications combined with entry-point sealing.
Once you know what you're dealing with, picking the right product becomes straightforward — here's how the top brands stack up.
Best Ant Killer Products of 2026: Head-to-Head Brand Comparison
Ant bait products have been rated the top choice by leading review outlets in 2026 for long-term colony elimination, consistently outperforming contact sprays for resolving infestations at the source (Source: Wirecutter, 2025). That does not mean sprays have no role — but bait should be the foundation of any serious treatment plan.
Here is how the top brands compare across every dimension that matters.
TERRO Liquid Ant Bait: Best Overall for Indoor Colony Elimination
Best used for: Odorous house ants, small black ants, sugar ants — indoors
TERRO uses borax as its active ingredient suspended in a sweet liquid that foragers cannot resist. Workers carry the bait back to the colony, share it through trophallaxis, and the slow-acting formula ensures they reach the queen before dying. This is exactly the colony-kill mechanism that makes bait superior to spray.
Time to results: Expect to see peak ant activity around the bait stations within 24–48 hours — this is normal and means it is working. Full colony elimination typically takes 3–7 days, sometimes up to two weeks for large colonies.
Cost per application: A 6-pack of TERRO T300 bait stations retails for approximately $7–9. For most small-to-moderate indoor infestations, one pack is sufficient for a full treatment cycle. That works out to roughly $1.25–$1.50 per station.
Pet/child safety: ⚠️ Use With Caution — Borax is low-toxicity but should be placed out of reach of pets and small children. Pre-filled bait stations reduce the risk of direct contact.
AMDRO Ant Block: Best Outdoor Perimeter Defense
Best used for: Outdoor perimeter treatment, fire ants, pavement ants, multi-species colonies entering from outside
AMDRO Ant Block uses hydramethylnon as its active ingredient in a granule format designed to be broadcast around the home's foundation and across yard perimeters. Workers carry the granules back to the colony as food, where the delayed-action toxin eliminates the nest over several days.
Time to results: Perimeter activity reduction within 1–2 weeks. Full colony collapse typically within 2–4 weeks depending on colony size and species.
Cost per application: A 24 oz. container (covers approximately 1,080 linear feet) retails for around $12–16. For a standard home perimeter treatment, one container typically covers two to three full applications, bringing the cost per treatment to approximately $5–8.
Pet/child safety: ⚠️ Use With Caution — Keep pets and children off treated areas until granules have been watered in and the area is dry. Not for indoor use.
Ortho Home Defense: Best Indoor Spray for Fast Knockdown
Best used for: Immediate visible ant elimination, creating indoor barrier lines, supplementing bait programs
Ortho Home Defense is a bifenthrin-based spray that kills on contact and leaves a residual barrier along baseboards, entry points, and wall edges. It is the strongest case for keeping a spray in your rotation — not as a primary treatment, but as a fast-knockdown tool when you need immediate results while waiting for bait to work.
Time to results: Immediate on contact. Residual barrier remains effective for up to 12 months indoors when applied to undisturbed surfaces.
Cost per application: A 1.33-gallon jug retails for $18–22 and covers up to 400 linear feet. For a typical home perimeter interior application, one container provides several full treatments, putting the per-application cost at roughly $6–9.
Pet/child safety: ⚠️ Use With Caution — Allow treated surfaces to dry completely before allowing pets or children in the area. Do not apply near food surfaces.
Raid Ant Killer: Budget Pick With Limitations
Best used for: Spot treatment, immediate knockdown of visible trails, temporary relief
Raid Ant Killer spray is widely available, inexpensive, and effective at killing ants on contact. Its limitations are the same as any contact spray: it does not reach the colony, and it can disrupt ant trails in ways that interfere with bait programs if used simultaneously.
Time to results: Immediate on contact. No residual colony effect.
Cost per application: Approximately $5–7 per can. Short-term contact kill only — not a cost-effective long-term strategy.
Pet/child safety: ⚠️ Use With Caution — Contains pyrethrins and cypermethrin. Keep away from pets and children during application; allow to dry fully.
Syngenta Advion Ant Gel: Best Professional-Grade Bait for Serious Infestations
Best used for: Severe infestations, multiple ant species, situations where TERRO has not resolved the problem
Advion uses indoxacarb as its active ingredient — a delayed-action compound that is the same class of product used by licensed pest control professionals. The gel format allows precise placement in cracks, along baseboards, and inside wall voids where liquid bait stations cannot reach.
Time to results: Forager activity typically peaks within 24–72 hours. Colony elimination in 1–2 weeks for most infestations.
Cost per application: A 4-tube box retails for approximately $25–35. Each tube covers significant square footage, and one box typically handles multiple full treatments, bringing the per-application cost to around $8–12.
Pet/child safety: ✅ Safe when dry and applied out of direct reach — indoxacarb has a favorable safety profile at application-level concentrations. Allow to dry before pet/child access.
Quick Comparison Table: Brand, Use Case, Speed, Cost Per Application, Pet Safety
| Brand | Best Use Case | Time to Colony Effect | Cost Per Application | Pet/Child Safety |
|---|---|---|---|---|
| TERRO Liquid Bait | Indoor colony elimination | 3–7 days | ~$1.50/station | Use With Caution |
| AMDRO Ant Block | Outdoor perimeter defense | 2–4 weeks | ~$5–8 | Use With Caution |
| Ortho Home Defense | Indoor fast knockdown + barrier | Immediate (contact) | ~$6–9 | Use With Caution |
| Raid Ant Killer | Budget spot treatment | Immediate (contact) | ~$5–7/can | Use With Caution |
| Syngenta Advion Gel | Severe/persistent infestations | 1–2 weeks | ~$8–12 | Safe (when dry) |
AMDRO vs. TERRO: Which Is the Best Ant Killer for Your Situation?
TERRO is the better choice for indoor infestations because its liquid bait is specifically formulated to attract sugar-feeding ants indoors, and the borax formula works slowly enough for workers to carry it back to the queen. AMDRO is the better choice for outdoor perimeter control because its granule format is designed for broadcast application around foundations and yards, and it handles a broader range of outdoor species including fire ants. For complete coverage, using both together gives you the most thorough indoor-outdoor defense.
How Each Product Works Differently
TERRO relies on liquid boric acid bait delivered via pre-filled stations — a passive, placement-based approach that requires no mixing or measuring. AMDRO uses hydramethylnon granules that need to be broadcast and watered in to activate, making it better suited to outdoor application where coverage area matters more than precision.
The active ingredients are different, the application methods are different, and the target environments are different. Comparing them as if they compete directly is like comparing a mousetrap to perimeter fencing — both have roles.
Indoor Use: Why TERRO Has the Edge
TERRO — Indoor Pros: - Ready-to-use, no measuring or mixing - Highly effective on the most common indoor species (odorous house ants, sugar ants) - Pre-filled stations reduce mess and limit exposure - Widely available and extremely affordable
TERRO — Indoor Cons: - Not effective against all species, especially protein-feeding ants - Requires patience — initial increase in ant activity before colony decline - Stations need to be replaced if bait dries out
Outdoor Use: Why AMDRO Wins the Perimeter Battle
AMDRO — Outdoor Pros: - Designed for large-area broadcast application - Effective against fire ants, pavement ants, and multiple outdoor species - Granule format resists washing away in light rain (though heavy rain requires reapplication) - Creates a sustained barrier when applied correctly
AMDRO — Outdoor Cons: - Not appropriate for indoor use - Requires watering in for activation - Longer time to full results compared to TERRO for visible ant reduction
When to Use Both Together
If ants are entering your home from outside — which is the case for the vast majority of kitchen ant problems — treating only indoors addresses symptoms while the source remains untouched. Apply AMDRO around your foundation perimeter and along the yard edge, and place TERRO bait stations at interior entry points simultaneously. This two-front approach cuts off the supply chain while eliminating the ants already inside.
How to Use Ant Killer Indoors: Tiny Kitchen Ants and Beyond
Small ants appearing in the kitchen are almost always odorous house ants or pavement ants foraging from an outdoor or wall-void colony. They are not random — they are following invisible chemical trails laid down by scouts who found a food or moisture source in your home.
Why You're Seeing Tiny Ants in Your Kitchen (And Where They're Coming From)
Kitchen ants are not a cleanliness problem — they are an access problem. A colony within 30 feet of your home can send foragers through gaps as thin as 1/16 of an inch around pipes, window frames, and utility penetrations.
The trail you see is the visible end of a supply line that extends back to thousands of ants you cannot see. Every time you spray and disrupt that trail, new scouts explore alternative routes — sometimes deeper into the home.
Step-by-Step: How to Place Bait Stations for Maximum Effectiveness
- Do not spray before placing bait. Residual sprays repel ants and disrupt the trails foragers use to find bait stations. If you have recently sprayed, wait 48–72 hours before placing bait.
- Identify active trails first. Watch where ants are traveling and place stations directly along the trail, not in random locations.
- Place stations near entry points. Look for gaps around pipes under sinks, along baseboards near doors, and behind appliances.
- Use multiple stations. For a kitchen infestation, 2–4 stations placed along the same trail network are more effective than one station.
- Do not move the stations. Once ants find a bait station, displacing it breaks the trail and resets the process.
- Leave the ants alone. Resist the urge to kill ants you see near the bait — they are doing exactly what you need them to do.
- Replace stations when bait runs out. Dry or empty bait stations are ignored. Check every 3–5 days during active treatment.
If you would rather skip the guesswork of selecting, sourcing, and combining products yourself, Remedy DIY Pest Control delivers a professionally formulated kit built for your specific location, ant species, and home type — the same class of products professionals use, at a fraction of exterminator costs. It is the practical middle ground between ineffective store-bought sprays and expensive pest control contracts.
⚠️ Warning: Spraying visible kitchen ants with a contact spray immediately before or during bait treatment is one of the most common ways to undermine your own results. Residual spray chemicals repel foragers, preventing them from reaching the bait and carrying it back to the colony. Worse, certain spray chemicals can signal danger to the colony, triggering it to split into satellite nests in new locations — potentially making the infestation harder to resolve (Source: Wirecutter, 2025). If you have already sprayed, give the area time to clear before deploying bait.
Common Indoor Application Mistakes That Undo Your Progress
The biggest mistake is panicking when bait activity increases. Seeing more ants around a bait station in the first 24–48 hours means the product is working. Removing or moving the station at this point restarts the process.
The second most common mistake is placing bait too far from active trails. Ants do not forage randomly — they follow pheromone highways. Bait placed even six inches off a trail may go untouched for days.
How Long Before Indoor Bait Starts Working?
Most homeowners see a significant reduction in visible ant activity within 3–5 days of correct bait placement. Full colony elimination takes 1–2 weeks depending on colony size and species. If activity has not decreased after two weeks, the bait is likely not on an active trail, has dried out, or you are dealing with a species that does not respond to sugar-based bait.
How to Use the Best Ant Killer Outdoor: Protecting Your Home's Perimeter
Outdoor treatment is where most homeowners have the biggest gap in their strategy. If ants are entering your home, they are coming from somewhere within a reasonable distance — and addressing the outdoor source is what prevents the cycle from repeating.
Where to Apply Outdoor Granules and Sprays for Maximum Coverage
The foundation line is your first priority. Broadcast granules or apply liquid bait in a continuous band around the entire perimeter of your home, extending 2–3 feet out from the foundation and 2–3 feet up the wall where possible.
Pay specific attention to entry points: door thresholds, utility penetrations, expansion joints in concrete, and any area where the foundation meets the soil. These are the highways ants use to move indoors.
How Often to Reapply Outdoor Treatments (And What Weather Does to Them)
Outdoor products degrade faster than indoor applications due to UV exposure, rain, and soil activity. Granule-based products like AMDRO need reapplication after significant rainfall (1 inch or more) and on a regular schedule during active ant season.
| Product Type | Recommended Reapplication Frequency | Rain Resistance |
|---|---|---|
| Granules (e.g., AMDRO) | Every 4–8 weeks, or after 1"+ rain | Low — water activates but heavy rain dilutes |
| Liquid perimeter spray | Every 90 days, or after heavy rain | Moderate — needs dry surface to bond |
| Outdoor liquid bait stations | Refill or replace every 30 days | High — enclosed stations protect liquid |
Creating a Full Perimeter Defense: The 3-Zone Strategy
3-Zone Perimeter Defense — Application Guide
Zone 1 — Foundation and Entry Points: Apply granules or residual spray in a 2–3 foot band directly against the foundation. Target all visible entry points with focused bait placement. Best product: Granules (AMDRO) or residual liquid spray.
Zone 2 — Yard Perimeter: Broadcast granules along the outer edge of your lawn or landscaping beds, especially areas adjacent to structures or pavement. Best product: Granules for broad coverage.
Zone 3 — Active Ant Mounds and Nesting Areas: Apply directly to visible mounds, rotting wood, tree bases, and any identified nesting sites. Use targeted drench or bait depending on species. Best product: Mound drench or bait granules for fire ants; borate bait for carpenter ants near wood.
Outdoor Pet and Child Safety: What You Need to Know
Most outdoor granule products require that pets and children stay off treated areas until the granules are fully watered in and the surface is dry — typically 30–60 minutes under normal conditions. Do not allow pets to eat granules directly, as product-level concentrations can cause digestive issues.
For homes with pets who have access to the full yard, liquid outdoor bait stations in enclosed housings offer a safer alternative to broadcast granules since the bait is contained and access is limited.
Long-Term Ant Prevention: How to Make Sure They Don't Come Back
Treating an active infestation resolves today's problem. Prevention is what stops the same problem from appearing every spring and summer. Most homeowners skip this step — which is why their store-bought products appear to "stop working" over time.
Sealing Entry Points: The Most Overlooked Step
Caulk is cheap. Replacing it around window frames, door thresholds, utility pipes, and foundation cracks once a year removes the physical access ants need to enter. No product compensates for a home that is structurally open to ant entry — foragers will simply find the unsealed gap.
Focus on the kitchen and bathrooms first, since these areas offer both access and the food and moisture sources ants are seeking.
Food and Moisture Control Inside the Home
Ants do not enter clean, dry homes by accident — they are following a signal. Remove that signal and you remove the incentive. Store open food in sealed containers, fix any leaking pipes under sinks immediately, and keep counters free of sticky residues that are invisible to you but obvious to a foraging ant.
Pet food bowls are one of the most overlooked ant attractants in the home. If you leave filled bowls out overnight, you are providing a consistent food source that will draw scouts regardless of what products you apply.
Seasonal Ant Activity: When to Treat Before Infestations Start
Ant colonies become most active in late spring as temperatures rise and the queen begins ramping up egg production. Applying perimeter granules in early spring — before the first signs of activity — is significantly more effective than responding to an active infestation.
A proactive application in March or April, followed by a second application in early summer, covers the peak activity window for most common species in temperate climates.
How a Maintenance Schedule Beats a One-Time Treatment Every Time
Products do not fail because they are weak. They fail because they are applied once and forgotten (Source: Knox Pest Control). A colony that is disrupted but not eliminated will rebuild. A perimeter barrier that degrades without reapplication leaves the home exposed.
A quarterly outdoor treatment schedule combined with indoor bait station replacement every 30–60 days during active season creates the sustained pressure that collapses colonies and prevents reinfestation. One-time treatments create the illusion of control — consistent maintenance creates actual control.
Homeowners often still have specific questions about timing, pet safety, and when to stop treating on their own — the FAQ below addresses the most common ones directly.
When to Call a Professional (And When You Definitely Don't Need To)
DIY ant control is effective for the vast majority of typical home infestations. Knowing where that line is saves you either money (by not calling unnecessarily) or time and structural damage (by not waiting too long when professional help is genuinely needed).
Signs Your Infestation Is Beyond DIY Control
Call a professional if: - You have seen large (6mm+) ants emerging from wall voids, ceilings, or wood trim — especially near moisture damage — suggesting active carpenter ant nesting inside the structure - Multiple DIY treatment cycles over 4–6 weeks have produced no reduction in activity - You are finding ant damage to wood — sawdust-like frass piles, hollow sounds in wall studs, or bubbling paint near wood structures - You have a confirmed fire ant infestation in a yard where children or pets are regularly present and mound counts are high - You suspect the colony is located inside a structural wall void that you cannot safely access
Try DIY first if: - You are seeing a trail of small ants entering from outdoors through a visible gap - Ants are confined to the kitchen or one area of the home - The infestation appeared recently (within the last 2–4 weeks) - You have not yet tried slow-acting bait — most infestations respond well to correctly placed bait - There is no visible structural damage or evidence of nesting inside walls
The Real Cost of Hiring an Exterminator vs. DIY Treatment
A single professional pest control visit for ant treatment typically runs $150–$300 for an initial treatment, with quarterly follow-up contracts ranging from $400–$800 per year. A complete DIY bait-and-perimeter program using professional-grade products costs $30–$80 for a full treatment cycle, with maintenance products adding $50–$100 annually.
For the overwhelming majority of typical household infestations, professional intervention is not necessary — it is just the default assumption when DIY products have failed.
Why Carpenter Ant Infestations Sometimes Need Professional Assessment
Carpenter ants nesting inside your home's structure present a unique challenge: the nest may be deep inside a wall void, and eliminating it requires locating and treating the void directly — not just placing bait at the surface. If you have identified carpenter ants (large, dark, near wood or moisture sources) and bait treatment has not resolved the issue within 3–4 weeks, a professional assessment for structural nesting is worth the cost. The risk is not the ants themselves — it is the structural damage that accumulates if the colony is allowed to continue excavating.
Frequently Asked Questions
What is the fastest-acting ant killer available?
Contact sprays like Raid and Ortho Home Defense provide the fastest visible knockdown — ants die on contact within seconds. For full colony elimination, Syngenta Advion Gel typically works faster than other bait options, with most colonies showing collapse within 1–2 weeks. If speed is the priority, use a contact spray for immediate relief and fast-acting gel bait simultaneously to address the colony.
Is TERRO safe for pets and children?
TERRO's active ingredient, borax, is low in toxicity at the concentrations used in bait stations, but it should not be treated as completely harmless. Pre-filled bait stations significantly reduce exposure risk because the liquid is enclosed. Place stations in areas pets and small children cannot access directly — behind appliances, under sinks, or inside a tamper-resistant bait station housing.
How long does it take for ant bait to kill the whole colony?
Most liquid bait products eliminate the majority of a colony within 1–2 weeks when placed correctly on active trails. Larger colonies or those in hard-to-reach locations can take up to four weeks for full collapse. The key indicator that bait is working is a surge in activity around the station in the first 24–72 hours, followed by a gradual decline.
Can I use outdoor ant killer inside my home?
No. Products labeled for outdoor use, including AMDRO granules, are not formulated for indoor application and should not be used inside the home. Outdoor products are designed for soil contact, larger application areas, and higher exposure tolerance. Using them indoors can result in overexposure to active ingredients and is not labeled or tested for interior use.
Why do I keep getting ants in my kitchen no matter what I do?
Recurring kitchen ants almost always mean one of three things: the colony was never eliminated (only surface ants were killed), entry points were never sealed, or a consistent food or moisture source is still attracting new scouts. Check for leaking pipes, unsealed food containers, and gaps around utility penetrations. A slow-acting bait program combined with perimeter treatment and entry-point sealing breaks this cycle.
What is the difference between ant bait and ant spray, and which works better?
Sprays kill ants on contact — fast, visible, and temporary. Bait exploits ant colony behavior to deliver a slow-acting toxin to the queen, collapsing the entire colony over days to weeks. For permanent elimination, bait is more effective. Sprays are useful for immediate knockdown and perimeter barriers but do not address the colony. The best approach combines both: bait as the primary treatment, spray as a supplementary barrier.
Do I need a different product for carpenter ants vs. regular black ants?
Yes. Common small black ants (odorous house ants, pavement ants) respond well to sugar-based liquid baits like TERRO. Carpenter ants are protein feeders and often do not respond to sugar bait — they require protein-based or dual-attractant bait formulas, and severe structural infestations may require void injection. Identifying your ant species before purchasing is the single most important step in selecting an effective product.
The Right Product for Your Situation — Make the Call Today
If you are seeing a trail of small ants moving through your kitchen, start with TERRO liquid bait stations placed directly on the trail. That resolves the majority of common household infestations within two weeks for under $10. If you are dealing with outdoor colonies entering from the yard or foundation, add AMDRO perimeter granules to cut off the source at the same time.
If the infestation has persisted through multiple treatment attempts or the ants keep coming back season after season, the issue is usually not the products — it is the formula, timing, or placement. Getting those three variables right is exactly where most DIY efforts break down.
