Check Price on Amazon

This three-pack delivers eighteen liquid bait stations built around the proven borax–sugar formula that targets the entire colony, not just the scouts. Users consistently report a noticeable drop in ant activity within 48 hours and complete clearance by day four, with many noting the colony remains gone for months afterward. The clear plastic housing lets you monitor the liquid level without opening the station, which is a practical detail when you are tracking bait consumption across multiple rooms.

EPA registration adds a layer of regulatory credibility, and the liquid bait’s slow action ensures workers have enough time to carry it back to the nest before dying. The borax ingredient is safe enough to use near pets when placed out of direct licking reach, and the traps work on a wide range of sweet-eating species including Argentine, odorous house, and ghost ants. Several long-term reviewers describe this as the only trap that solved recurring invasions that sprays and granules could not touch.

The liquid can spill if the station is tipped over, and the opening mechanism requires a slight twist that can be frustrating for some users. Once placed flat on a counter or baseboard, the station stays stable, but avoid placing it on uneven outdoor surfaces where wind or rain could knock it sideways. Overall, this is the most reliable colony eradicator in the lineup for typical household ant species.

The two-pack Terro T300 is the classic entry point into liquid baiting and is especially lethal against Argentine and sweet-eating ants. Verified owners describe a scenario where ants swarm the station for the first day or two, then taper off dramatically by day three, and vanish entirely within four days. The borax–sugar solution is identical to the larger pack, so you are getting the same colony-killing chemistry in a smaller, cheaper dose for light infestations.

Reviewers highlight the safety profile of borax around children and pets; multiple cat owners confirmed the traps worked without any adverse effects on their animals when placed in out-of-reach spots. The liquid bait is designed so ants drink it and share it, which is the mechanism that collapses the colony rather than just culling the visible foragers. The stations are ready to use out of the box with no mixing or activation required.

The main trade-off is that two stations may not cover a large multi-room infestation, and the liquid can leak slightly if the station is handled roughly during shipping or placement. Some users recommend putting the trap on a small piece of cardboard to catch any seepage. For a single kitchen counter or bathroom corner, this is the most cost-effective solution that still delivers full colony kill.

Ortho’s offering uses Abamectin B1 instead of borax, which makes it faster on initial contact but less effective at spreading through deep colonies over time. The eight stations include four different food-based attractants, a strategy designed to appeal to a broader range of ant species including acrobat, Argentine, odorous house, and pharaoh ants. However, the manufacturer explicitly excludes carpenter, fire, and harvester ants, so verify your species before buying.

The child-resistant plastic housing is built with ant-sized entry holes that prevent tiny fingers from accessing the gel, and the sealed stations leave no sticky residue on floors or baseboards. Users report visible results within 24 hours and complete clearance in three to four days for mild infestations. The plastic construction is more durable than the Terro liquid stations, making it a better fit for apartments or commercial spaces where traps might be bumped or moved during cleaning.

The downside is that Abamectin B1 works faster than borax, which can kill workers before they return to the nest, potentially reducing colony-wide impact. Some reviewers found the traps ineffective on outdoor patios and front steps, suggesting the gel dries out faster in sun-exposed areas. For indoor use in a controlled environment, the stations are clean and safe, but for heavy infestations requiring deep colony penetration, the borax-based Terro options remain superior.

The Pic HomePlus stands apart because of its metal tin construction, which resists chewing from dogs and other animals—a common failure point for plastic stations left in garages or on patios. Users with large dogs report placing these under bricks or rocks with no damage to the housing. The stations use four food-based attractants and start killing worker ants within 24 hours, though the active ingredient formula is not disclosed as specifically as Terro’s borax content.

The child-resistant design requires a screwdriver to open the holes, which adds an extra layer of safety but also means you need a tool on hand to activate each station. Long-term buyers have used these for years during spring ant invasions, placing them between window screens and glass to intercept ants before they enter the home. The weatherproof metal housing holds up through rain, sun, and seasonal temperature swings without warping or cracking.

The main limitation is that users report slower colony elimination compared to liquid baits, with some seeing only a reduction in ant numbers rather than complete clearance. The metal tin is not transparent, so you cannot monitor bait consumption without opening the station. For outdoor perimeter defense and areas where plastic would be chewed through, this is a durable alternative, but it may not deliver the deep colony kill that borax liquid baits provide.

This bulk Terro pack provides eighteen pre-filled liquid bait stations that cover multiple rooms or a moderate-sized home with ease. The same borax-based formula that has made Terro the most-recognized name in ant bait is delivered here in a value configuration that reduces per-station cost without sacrificing performance. Verified users describe initial ant swarming on day one followed by a wave die-off by day three, with the colony fully eliminated by day four.

The stations are ready to use straight from the box, and the liquid bait does not dry out quickly, giving you a treatment window of several weeks. Reviewers specifically note that this pack is the best option for tiny black crazy ants and Argentine ants, two species that are notoriously difficult to control with sprays. Some users pair these indoor stations with outdoor granular baits for a perimeter defense strategy that keeps ants from re-entering after the colony is wiped out.

The sticky liquid can create a mess if the station is tipped or the opening is handled carelessly, and some customers recommend taping the stations to a piece of cardboard for added stability. The clear plastic housing is less robust than the Ortho plastic stations, so rough handling during shipping can cause minor leaks. For homeowners who want maximum coverage with a formula that has decades of proven results, this bulk pack delivers the best per-station value in the premium tier.
