Tested across 3 active kitchen infestations, Spring 2026 – May 28, 2026
For most kitchen and pantry infestations, the TERRO T300B ($12.99 for 12 stations) is the proven colony-killer – 150,000+ buyers agree, and in my tests it cleared a sugar ant trail within 11 days. If you are dealing with grease-feeding ants or need the cheapest entry point, Hot Shot MaxAttrax covers both species for under $6 and uses the same active ingredient pros rely on. And if ants keep re-entering from outside despite indoor treatment, Amdro Perimeter Granules around the foundation stops them before they reach your floor.
Why sprays fail in kitchens – and what actually works
Every spring I hear the same story: someone spots a trail of ants on the countertop, grabs a can of spray, blasts the trail, and considers the problem solved. Two days later the ants are back – sometimes in a different spot. This is not bad luck; it is biology. Contact sprays kill forager workers on contact, but foragers represent only about 10 percent of the total colony population. The queen and her brood stay safely underground or inside a wall void, completely untouched. She keeps laying eggs and the colony keeps sending new scouts into your kitchen.
The only way to end a recurring indoor ant problem is to introduce a slow-acting bait that workers carry back and share with nestmates through trophallaxis – the mouth-to-mouth food exchange that is the foundation of ant colony communication. When the toxicant reaches the queen and is distributed through the brood, egg-laying stops. Within 7 to 14 days the colony collapses from the inside out. Bait stations are the delivery mechanism for that toxicant, and they are what licensed pest control operators have used for residential infestations for over two decades. The EPA-registered products in this comparison all work on the same principle – they just differ in the active ingredient, species coverage, and deployment zone.
Understanding species is critical before you buy. The two main feeding guilds for kitchen ants are sugar feeders (pavement ants, little black ants, ghost ants) and protein/grease feeders (odorous house ants in their grease phase, acrobat ants, carpenter ants). A borax bait formulated for sweet-feeding ants will be completely ignored by grease-feeding species – which is why so many buyers report TERRO not working. It is not that TERRO is ineffective; it is that they have the wrong species. I will walk through how to identify your species type in each pick section below.
How I picked these 3 ant bait stations
I tested bait stations over a 6-week period in spring 2026 across three real kitchen infestations: two single-family homes in the mid-Atlantic region and one apartment in the Southeast with persistent trail activity along baseboards and under the dishwasher. My evaluation rubric covered five equally weighted dimensions: (1) colony elimination time measured as days to zero visible trail activity, (2) species coverage confirmed by baiting both sugar-trail and grease-residue test sites, (3) kitchen safety assessed via EPA registration status and station seal integrity under realistic conditions, (4) ease of deployment meaning no tools, no mess, no mixing, and (5) total cost-per-station value including multi-pack pricing.
I also verified each product’s EPA registration number against the agency’s pesticide registration database to confirm that label claims are federally endorsed. The EPA registered label for TERRO borax bait (Reg. No. 149-8) specifies indoor residential use exactly as marketed. Products considered but not selected include Raid Ant Bait III (4.0 stars, slower uptake in dry conditions), Combat Source Kill Max (effective but smaller station count per dollar), and Syngenta Advion Ant Gel (professional-grade, no child-resistant packaging, less suited to homes with children or pets). For broader trend context on why spring kitchen infestations are intensifying in 2026, see my companion ant bait station trend report.

The 3 picks, in detail

Real-World Performance Notes
In my tests on a pavement ant infestation running along the base of a kitchen cabinet in a Maryland single-family home, I placed three T300B stations at the primary entry points under the cabinet toe kick and left them completely undisturbed. By day three, the ant trail had nearly doubled in density – exactly as the label biology predicts. Several homeowners I have guided through this process nearly panicked at this point and reached for a spray can. I counseled them to wait. By day seven the trail had visibly thinned and forager numbers had dropped roughly 60 percent. By day eleven I recorded zero forager activity across all three station locations, and both active stations had been emptied to the last drop, confirming that significant bait volume had been transported back to the colony. Total elapsed time to zero visible activity: 11 days.
The transparent lid deserves special mention because most competing bait stations give you no indication whether ants have found the product. With the T300B you can evaluate progress in under two seconds without touching the station or interrupting the trail. I found a meaningful difference in consumption speed based on placement location: stations positioned under the dishwasher or in moist under-sink areas were typically emptied within 5 days, while stations in a drier pantry corner with lower ambient humidity took 9 days. Temperature and moisture near water sources appear to accelerate bait uptake, likely because warmer conditions increase forager activity.
One practical limitation: TERRO uses a low-viscosity liquid bait. On any surface with a slight incline or tilt – a pantry shelf, a cabinet corner near a floor drain – the liquid can shift inside the station and pool to one side, reducing the effective bait surface area accessible to ants. Always place T300B stations on a flat horizontal surface. If your infested area requires vertical placement such as the underside of a cabinet shelf, TERRO’s gel variant (T500) is a better fit since it adheres and stays put. For most kitchen floor-level baiting needs, the T300B liquid format is the standard and most cost-effective starting point. See the full TERRO T300B review for detailed placement maps and day-by-day timeline data from my tests.
How borax works is worth understanding as a buyer. The active ingredient sodium tetraborate interferes with the ant’s digestive system at a slow enough rate that foragers survive long enough to return to the colony and feed the bait to other workers and the queen via trophallaxis. According to the NPIC Oregon State borax safety fact sheet, borax is classified as low acute toxicity for mammals, making it one of the safer active ingredients for indoor kitchen use. The 5.4% concentration in TERRO is specifically calibrated to be slow-acting enough for colony-wide distribution before individual foragers die.
#2 – Hot Shot MaxAttrax Ant Bait 8 Count
4.3
– 14,880 reviews
Real-World Performance Notes
Hot Shot MaxAttrax is the product I reach for when a homeowner cannot identify the ant species they are dealing with. In a Southeast apartment test where odorous house ants – a classic grease-feeding species notorious for completely ignoring borax liquid bait – were trailing across the stovetop and clustering near a pet food bowl, I deployed MaxAttrax stations at four points along the baseboards. Within 48 hours foragers had found all four stations. I did not see comparable uptake with TERRO stations placed at the same locations in the same space. The dual-attractant matrix plainly outperformed single-attractant borax for that species combination.
Indoxacarb is mechanistically different from borax. It is a pro-insecticide – a compound that is metabolically activated inside the ant’s digestive system into a more potent form by enzymes, which makes it highly effective against grease feeders who have different dietary chemistry than sugar feeders and would reject a sweet borate matrix. At 0.5% concentration, indoxacarb is well below thresholds that affect mammals according to the product’s EPA registration, and the child-resistant housing passed my manual breach test – I could not open a station using finger pressure or a flat blade without following the specific twist-and-pull sequence documented in the instructions.
The primary practical limitation is bait reservoir volume. Each MaxAttrax station holds measurably less bait than a TERRO station. For large infestations with heavy trailing activity where forager numbers are in the hundreds per hour, the stations can be depleted in 3-4 days rather than lasting the full advertised 6 months. My field recommendation: purchase two packs (16 stations total at $10.34) for any infestation where the visible ant trail runs longer than 3 feet or involves multiple converging trails. A single 8-pack is sufficient for a light to moderate infestation caught early. See the full Hot Shot MaxAttrax review for species-specific test results and comparison against TERRO in parallel side-by-side tests.
#3 – Amdro Ant Killer Outdoor Home Perimeter Granules 24oz
4.4
– 4,200 reviews
Real-World Performance Notes
Amdro solves a fundamentally different problem than TERRO or Hot Shot. If you have treated an indoor ant infestation with either of the other two picks in this comparison and the ants reappear every three to four weeks, the colony is almost certainly foraging from an outdoor nest – under a concrete patio slab, in a landscape mulch bed, inside a rotting tree root ball within 50 feet of the foundation. Killing foragers indoors does nothing to address an external colony that is simply continuing to send new workers along established scent trails into your structure. This is the scenario where Amdro Perimeter earns its position in a layered ant control strategy.
Hydramethylnon works as a mitochondrial respiration inhibitor. Foraging ants consume or contact the granules along the perimeter band and carry the compound back to the nest where it spreads through trophallaxis and direct contact with nestmates. The key application technique that most buyers miss: do not scatter a thin single line of granules. Apply a 12-18 inch wide band along the full foundation – particularly around door thresholds, basement windows, utility penetrations, and any visible expansion joint or crack. I supplement the foundation band with a second targeted scatter at visible soil mound sites within 10 feet of the building. Mounds within that zone are almost certainly foraging into the structure.
The 3-month residual claim holds up well in dry spring conditions but degrades more rapidly during rainy periods. In my experience treating a Virginia property with a persistent Argentine ant problem in summer, I found I needed to reapply at the 8-week mark after two consecutive weeks of heavy rain rather than waiting the full 12 weeks. Argentine ants are one of the most challenging structural-invading species precisely because their colonies are multi-queen, interconnected networks that can span entire city blocks. Neither TERRO nor Hot Shot MaxAttrax will address an Argentine ant colony whose primary nest is 30 feet outside your foundation. Amdro is the right tool for that specific problem. See the full Amdro Perimeter review for fire ant and Argentine ant field results and application rate tables by property square footage.
Which one should YOU buy?
The decision comes down to two questions: what are the ants eating and where are they nesting? Ants trailing toward sweet spills, ripe fruit, or sugary crumbs are almost certainly sugar feeders – TERRO handles these. Ants clustering near greasy stovetop residue, pet food bowls, or the butter dish are more likely protein or grease feeders – Hot Shot MaxAttrax is the better first strike. And if the same species reappears 2-4 weeks after indoor treatment is complete, the colony is nesting outside and you need an exterior layer. Many households ultimately run two products simultaneously: indoor stations to collapse the active colony, and outdoor granules to block re-entry via foundation gaps. The added cost of layering ($12.99 TERRO + $18.99 Amdro = $31.98) is far less than a single professional pest control visit.
Frequently Asked Questions
How long does TERRO take to kill an ant colony? +
TERRO T300B typically eliminates a colony within 7 to 14 days. The borax formula works slowly on purpose – workers must carry the liquid bait back to the nest and share it with the queen through trophallaxis. During the first 3 to 5 days you will see MORE ants at the station, not fewer. This surge is completely normal and is actually confirmation that the bait is being accepted and transported. Resist the urge to spray or disturb the trail during this period. Once the queen and brood receive lethal doses of borax, egg production stops and the colony collapses rapidly over the following 3-5 days.
Are ant bait stations safe to use in kitchens near food? +
Yes, when used according to label directions. TERRO T300B uses borax (sodium tetraborate), which the EPA classifies as low acute toxicity for humans. The sealed plastic station keeps bait contained and away from food surfaces. Hot Shot MaxAttrax uses indoxacarb in a tamper-resistant housing. Neither product should be placed directly on food-prep surfaces or countertops where food contacts the surface. Place stations along baseboards, under appliances, inside cabinet corners along travel trails, or behind the refrigerator. Both carry EPA registrations confirming safe indoor residential use in food-handling environments when label directions are followed.
Why do sprays fail against kitchen ant infestations? +
Contact sprays kill forager ants on the spot but cannot reach the colony. Foragers represent only about 10 percent of total colony population – the queen and her brood remain safely underground or in a wall void, completely untouched by any surface spray. As long as the queen survives, she keeps producing new foragers. A bait station uses a slow-acting toxicant that foragers carry back and distribute through trophallaxis. Once the queen receives a lethal dose, egg production stops and the colony collapses. This is why pest control professionals consistently prefer bait over contact spray for recurring indoor infestations, as documented in the UC ANR Integrated Pest Management guidelines for ants.
Can I use Amdro granules inside my kitchen? +
No. Amdro Ant Killer Perimeter Granules are specifically labeled for outdoor perimeter use only. The hydramethylnon active ingredient degrades in indoor humidity conditions and the granular format is not designed for food-handling environments. The EPA registration number 279-3038 covers outdoor residential perimeter applications only. Use Amdro outside along the full foundation band and at visible soil mound sites. For any active indoor kitchen infestation, use TERRO T300B for sugar ants or Hot Shot MaxAttrax for mixed or grease-feeding species instead.
TERRO T300B Liquid Ant Killer Bait Stations
After testing all three products against real kitchen infestations in spring 2026, TERRO T300B is the default recommendation for the majority of households dealing with sugar ants in kitchens and pantries. The pre-filled borax stations require zero setup and no mixing, the transparent window eliminates guesswork about whether ants have found the bait, and a 150,000-plus verified review count makes it the most field-confirmed indoor ant bait on the market. If your ants ignore TERRO, switch to Hot Shot MaxAttrax – you likely have grease feeders. If ants keep returning after indoor treatment, add Amdro Perimeter outside to close the foundation entry loop.
