Terro Ant Bait Review: Finding the Ants for You

An ant eating a bait

No matter how careful you are about keeping your house clean, it seems that ants always find a way to invade the kitchen and bathrooms, their miniature armies marching toward food and water sources that you can't even begin to guess at. Before you panic, read this Terro ant bait review to see if these easy-to-use bait stations might be a good solution to your unwanted visitors.

What Are TERRO T300 Liquid Ant Baits?

Terro Liquid Ant Baits are small, single-use stations that come preloaded with a chemical attractant and poison. Worker ants find the bait and then take it back to the rest of their colony. Their chemical trail then leads other ants to the stations that are now recognized as a food source.

This system takes care of one of the worst things about ants: the fact that you only see a small portion of the ants that actually make up the colony that is invading your home. Terro liquid ant bait works slowly. This leaves plenty of time for the workers you see to take it back to feed to the rest of their colony. It can effectively destroy ants at virtually every stage of their life cycle so that you can kill an entire colony with one application of bait stations.

Product Specs

Terro Liquid Ant Baits use a little over five percent of borax (Sodium Tetraborate Decahydrate) to effectively poison many types of ants. The borax is suspended in a sweet-tasting solution that is designed to attract ants seeking food and water. This type of bait will not work on fire ants or carpenter ants, but it is used to target many of the sugar-loving species that commonly invade your home.

How to Ensure Success


Terro Liquid Ant Baits are a relatively inexpensive product that makes pretty big claims about killing ant colonies. They fall on the lower end of the pricing range that covers all the ant baits in this Terro Ant Bait review, which is roughly $5 to $10.

A Terro Ant Bait Review: How It Compares

We picked a few similar products available on the market to see how they compare in our Terro ant bait review:

  • Harris Ant Killer, 3oz Liquid Borax Value Pack
  • Ortho 0464812 Home Defense Liquid Ant Bait
  • RESCUE! Ant Baits

Product Comparison Table 

TERRO T300 Liquid Ant Baits

  • Ease of Use
  • Design Quality

This bait station is an incredibly simple design. The clear plastic allows you to monitor both ant activity and the remaining levels of the sweet bait and poison in each station. While these are not made with high-end materials, they are more than sufficient for a temporary bait station designed to keep kids and pets out.

Harris Ant Killer, 3oz Liquid Borax Value Pack

While these Harris Ant Killer liquid bait stations contain the same active ingredient at their Terro counterparts, they are much more complicated to use. In fact, these are the only bait stations in our Terro ant bait review that require you to handle the poison by placing it into empty stations. On the other hand, this package comes with a very generous 3-ounce bottle of bait/poison and nine individual bait stations.

If you have small children or pets, then you will want to be extra careful in placing these stations where they cannot be accessed. This is because the bait is placed into open-topped trays where a child or pet could easily touch or eat it.

  • Ease of Use
  • Design Quality

While it doesn't have an inherently bad design, this liquid ant bait pales in comparison to the others in our Terro ant bait review. The trays have open tops so children and pets can easily access the poison. However, because the bait is added to the stations as needed, they may last longer than other, preloaded bait stations. If cost is a concern, this could be your best choice.

Ortho 0464812 Home Defense Liquid Ant Bait

This is the only product in our Terro ant bait review that uses a chemical other than Borax. Instead, Ortho has opted to utilize low levels of Spinosad poison to eliminate ants at all stages of their life cycle.

Ants are attracted to the water and food inside each bait station. Once they gather some up, they take it back to their colony where it is shared with other ants, including larvae and the queen. This is designed to effectively destroy the colony and eliminate your ant infestation.

  • Ease of Use
  • Design Quality

Snap the end and set the trap: it really is that straightforward to use these Ortho bait stations. We did notice in our Terro ant bait review that you have to handle the used bait station to check poison levels. This is in contrast to the Terro stations, where clear plastic construction allows you to see at a glance if any bait remains.

RESCUE! Ant Baits

These ant bait stations attract numerous types of household ants with two distinct types of bait. One is for ants that are attracted to sugary or sweet foods. The other is rich in protein for ants who find that more appealing. Each is packed with the chemical Borax.

As ants carry the bait back to the colony, it is fed to workers, the queen, and larvae. This means that Rescue! Ant bait can wipe out not only the ants currently invading your space but also the ones that haven't fully developed yet.

  • Ease of Use
  • Design Quality

If an ant bait station could be cute or decorative, then the Rescue! Ant Baits would win that accolade in our Terro ant bait review. They are small square bases with holes for ants to get in and out through. A slightly opaque top allows a somewhat obstructed view of bait levels within the station.
Although these are listed as resistant to tampering by children, we felt their simple, almost block-like design might actually attract a youngster.


Overall, this Terro ant bait review awarded a score of 4.5 to the easy to use liquid ant baits. We were very impressed with the preloaded and easy to open stations, which are designed so you never have to touch the poison inside.
