Terro Liquid Ant Bait Station 2oz 6-Pack (T300)

Terro’s liquid ant bait stations solve the spring ant invasion problem that Montana homeowners face when pavement ants emerge from winter dormancy. The 5.4% borax formula in a 94.6% sweet attractant base draws worker ants in, then the slow-acting poison gives them time to haul it back to the colony. Three to four days later, the queen’s dead and the colony’s done.

Each pack includes 6 pre-filled stations totaling 2.2 fl oz of bait. No mixing, no spilling — just snap off the tab and set them down. The transparent housing shows exactly how much bait remains and whether ants are taking it.

Colony Elimination Through Worker Distribution

The borax concentration hits the sweet spot for ant control. Too much borax and ants reject the bait. Too little and it won’t kill the colony. Terro’s 5.4% sodium tetraborate decahydrate balance means worker ants live long enough to share the poison throughout the nest before dying. The digestive system disruption spreads from workers to larvae to the queen.

The formula targets ten specific ant species: Argentine, ghost, cornfield, pavement, acrobat, white-footed, little black, odorous house, crazy, and big-headed ants. It won’t work on carpenter, fire, or harvester ants — those species need different baits. Pavement ants plague Montana properties after freeze-thaw cycles crack concrete and create nesting sites. Odorous house ants — the ones that smell like rotten coconut when crushed — also take this bait readily.

Strategic Placement Maximizes Results

Place stations along baseboards, under kitchen appliances, on windowsills, in corners near ant trails, and under sinks. For large infestations, deploy all 6 stations rather than holding some back. More bait points mean more workers find it faster.

The initial ant swarm around stations disturbs some users, but that surge means the bait’s working. Ants increase before they disappear — patience pays off as the colony-wide poisoning takes 3-4 days. Keep other pesticides away from bait stations. Spraying near the bait repels ants and ruins the whole operation.

Replace stations every 3 months or when empty. The stay-fresh tab seal maintains bait quality until opened, so unopened stations store well for next season. The liquid can get sticky if stations tip over — place them on flat, stable surfaces.

For Montana’s indoor ant problems — particularly when pavement ants invade during spring thaw or odorous house ants seek winter shelter — these ready-to-use stations offer a proven solution that targets the entire colony, not just visible workers. The borax formula’s track record, combined with strategic placement and a few days’ patience, delivers consistent colony elimination.

Frequently Asked Questions

Q: Will these work on carpenter ants in my log home? A: No. Terro liquid bait only attracts sweet-eating ants. Carpenter ants, fire ants, and harvester ants need different bait types. Carpenter ants require protein-based baits or direct nest treatment.

Q: How long before I stop seeing ants? A: Expect more ants initially as workers recruit nestmates to the bait. Colony death typically occurs in 3-4 days, though stragglers may appear for another few days as the nest fully collapses.

Q: Can I use these outdoors in Montana weather? A: The stations work in enclosed patios and garages, but they’re designed for indoor use. Terro makes specific outdoor stakes for exterior ant problems. Montana’s temperature swings and moisture would degrade indoor stations quickly.

Q: Why do the ants ignore my bait stations? A: Ants’ dietary needs shift seasonally. Spring ants often crave proteins for larval development, while summer ants want sugars for energy. If you’re dealing with non-sweet-eating species like carpenter ants, they won’t take this bait. Try protein-based baits or call a professional.

Q: Are these safe around pets? A: The EPA signal word is “CAUTION” and stations feature child-resistant design. While borax has relatively low mammalian toxicity, keep stations where pets can’t chew them open. The sweet bait attracts dogs as readily as ants.
