Quick verdict
The TERRO T300B liquid ant bait stations are my top pick for most homes. The borax-based liquid attracts worker ants that carry it back to the colony, targeting the queen and nest rather than just the ants you see, and the 12 ready-to-use stations need no setup indoors.
Terro
The TERRO T300B uses a borax-based liquid that worker ants carry back to the nest, which the maker says kills the queen and the entire colony rather than just visible ants. The 12 ready-to-use stations need no setup and sit along baseboards, corners and countertops where ants travel. It targets common household ants and keeps working for weeks as ants keep feeding.

Why you should trust this guide
I look at ant bait stations the way someone watching a trail of ants cross the kitchen counter would, focusing on how the bait works, whether it targets the whole colony, and where each station is meant to be placed. The key thing to understand is that good baiting kills slowly on purpose, because worker ants need time to carry the bait back to the nest and the queen, so a station that wipes out visible ants too fast can actually leave the colony intact.
My goal is to help you choose between ready-to-use and refillable stations, and between indoor and outdoor placement. Ready-to-use baits are convenient, refillable stations are economical and let you pick your own bait, and outdoor stakes stop ants before they get inside. I try to be honest about the trade-offs, because refillable stations need you to buy bait separately, and colony control takes patience regardless of brand.
How we evaluated
I evaluated these stations on whether the bait is designed to reach the colony and queen, whether they come ready-to-use or need your own bait, their indoor or outdoor placement, and safety features like child-resistant or covered designs. Since these are registered pest products, I relied on each maker’s stated approach and active ingredient rather than inventing efficacy numbers.
I did not deploy these against an ant infestation myself, so I am not quoting kill rates or timelines from personal use. My assessment rests on comparing what each maker states about the bait, the colony-targeting method and the intended placement, checking those claims for consistency, and pointing out where a station is refillable, outdoor-only, or otherwise suited to a particular situation.
What to look for
- Colony targeting: the best baits are carried back to the nest to reach the queen, not just the visible ants.
- Ready-to-use or refillable: ready stations are convenient, refillable ones are economical but need separate bait.
- Indoor or outdoor: match the station to placement, with stakes for the perimeter and enclosed stations for counters.
- Active ingredient: borax-based liquids are a common, proven approach for household ants.
- Number of stations: more stations let you cover trails, entry points and multiple rooms at once.
- Safety design: child-resistant or covered stations are safer around kids and pets.
- Patience: colony control often takes two to four weeks, so give the bait time to work.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking.

They are placed indoors in corners, along walls and near entry points, and the eight-count pack covers common problem areas. Place all baits at once for best effect.

Effective baits are carried back to the nest to reach the queen, so they target the whole colony, not just visible ants.
Ready-to-use or refillable
Ready stations are convenient, while refillable holders are economical but require you to supply your own bait.
Placement
Match the station to indoors or outdoors, using ground stakes for the perimeter and enclosed baits for counters.
Active ingredient
Borax-based liquid baits are a common, proven choice for a range of household ant species.
Number of stations
More stations let you cover trails, entry points and multiple rooms in one placement.
Safety design
Child-resistant or covered stations are safer to place around children and pets.
Our verdict
The TERRO T300B liquid ant bait stations are my top pick for most homes. The borax-based liquid attracts worker ants that carry it back to the colony, targeting the queen and nest rather than just the ants you see, and the 12 ready-to-use stations need no setup indoors.
FAQs
That is normal at first. Worker ants need to feed and carry the bait back to the colony, so you may see more activity before numbers drop. Full colony control often takes two to four weeks.
They can be. Reusable stations like the Qualirey and Catchmaster let you choose your own liquid bait and use them year after year, but remember the bait is sold separately and they need refilling and cleaning.
Use indoor stations along baseboards and counters where ants travel, and outdoor stakes around the perimeter to intercept colonies before they enter. Many homes benefit from using both together.
Look for child-resistant or covered designs, like the Raid baits or stacked Catchmaster stations, and always follow the label. Place stations where curious pets and children are less likely to reach them.
