The Bottom Line
When you see ants traveling in your home, there’s only one thing to do, and that is to get rid of them. When you only kill the ants you can see, you’re targeting the worker ants. The remainder of the colony will stay safe if you aren’t getting to the source.
Terro Outdoor Liquid Ant Baits are made to not only kill the ants you see traveling, but also the ants you don’t see back in the colony. Terro’s formula contains borax which is highly toxic to ants and other pests, but they’ve made it a slow-acting kill allowing the ants to eat some and take some back to feed their colony multiple times before killing them all off.

Terro Outdoor Liquid Ant Baits Review
Terro Outdoor Liquid Ant Baits are easy-to-use, pre-filled bait stations that attract and kill all common household ants that you see and the ones you don’t. You can place these bait stations anywhere. The package comes with stakes to set the stations on so you can put them in the ground without fear of them coming out. If your ant issue is on a deck or in your garage, these bait stations will also work well without the stakes.
Ease of Use
Terro ant baits are easy to set up since all six liquid ant bait stakes in a package are pre-filled and ready-to-use. Whether you need to use them in your yard with the stakes, or just flat on your deck or garage, the baits are an easy solution. When you find the trail of ants, press the top down and twist to break the seal on the inside. Once the seal breaks, the liquid bait flows into the reservoir to attract and kill the ants after they ingest the liquid. You might see an influx of ants at first, but they will die off after a few days.
Active Ingredients
For these outdoor liquid ant baits, Terro used borax as their main ingredient. It has a low level of toxicity for humans, but it is deadly to ants. It’s slow killing, which allows for each worker ant to return to the colony and share the bait with the rest of them. It also gives enough time for each ant to make multiple trips between the colony and the bait, creating a trail of pheromones. This trail indicates to the other ants that a food source has been found and helps lead more ants there.

Borax is also toxic to pets. If you have pets that roam around the backyard unattended, this product might not be the best for you.
Is Terro Outdoor Liquid Ant Bait Safe for my Family and Pets?
Because the active ingredient is Borax, it is safe for humans to be around due to its low toxicity level. It is still toxic if ingested, so make sure it’s in a place where children can’t get a hold of it. Borax is also toxic to pets. If you have pets that roam around the backyard unattended, this product might not be the best for you. The bait containers are mostly closed and have small ramps on the bases that allow the ants to travel in and out, but they are not pet-proof. If a dog decided to chew on the bait station, it might break through to get to the liquid inside.
Do Terro Outdoor Liquid Ant Baits Work?
Terro receives rave reviews for its outdoor liquid ant baits. We read through hundreds of Amazon reviews where customers even left updates on just how well these bait stations have worked for them over long periods. This product has proven to work on the most stubborn ants, such as carpenter ants, Argentinian ants, and black ants.
A few customers had issues with the set-up of the bait station as the white cap is meant to be pushed down and twisted a little to break the seal on the liquid. These customers mentioned that the lid is a bit flimsy. However, once pushed down into position, it is clipped on tightly by four surrounding clips. Another customer had an issue with raccoons stealing the stations, but the product itself worked great.

Suggested Application
These baits are ideal for large ant infestations because they come with a pre-filled cup of a liquid solution that will take care of your ant problem. Terro suggests that you place them near areas where you’ve seen ants, and to secure baits with the provided stakes if you are putting them in the ground. If you are placing them in a garage or on a deck where they can’t go into the ground, place them near where you see ants, but make sure to secure the station down if you have pets or other outdoor creatures that travel through that area. They are weather-proof bait stations, which prevents them from drying out or becoming contaminated by rain.

How do Terro Outdoor Liquid Ant Baits Work?
The best way to use Terro Outdoor Liquid Ant Baits is to find where the trail of ants is and where they’re coming from so that you can accurately place the bait station near the ants’ path. These ants that you see marching in plain view are the worker ants, and they will eat the liquid bait and carry it back to feed to the rest of the colony.
The active ingredients in Terro’s formula will ultimately kill the worker ant, but instead of the kill being immediate, it will slowly interfere with the ant’s digestive system, giving the ant more than enough time to return to the colony with bait to share. By doing this, Terro gets rid of the ants you see and the ones you don’t to offer complete control.
Check the traps periodically so you know when it’s time to replace. They’ll usually last about 30 days, or until all the bait is gone.

Terro Outdoor Liquid Ant Baits vs. Amdro Ant Block Home Perimeter Ant Bait Granules
Both Terro liquid ant baits and Amdro granules are made to kill the entire colony instead of just the ones trying to enter your home, and both are extremely affordable products. Some of the main differences between Amdro’s ant bait granules and Terro’s outdoor liquid ant bait is that Amdro’s is a granule, which means it is not weather-proof. You would need to reapply after it has rained, but only after the ground has dried. Terro’s is a weather-proof container that allows its bait to keep working even after it has rained heavily. Neither product is safe to use around pets, but Amdro claims it is OK for pets to be around once the dust has settled.
While they both work hard to keep ants out of your home, Terro is more convenient to use because it is a set and forget bait station that comes pre-filled. Amdro Ant Block Home Perimeter Ant Bait Granules need to be spread around the entire perimeter of your home.
Terro Outdoor Liquid Ant Baits vs. Terro Ant Killer Plus Shaker Bags
Terro Outdoor Liquid Ant Baits and their Ant Killer Plus Shaker Bags are similar products as far as what they are made to do. The shaker bags from Terro are an easy way to spread granules around the perimeter of your home, and they kill ants, fire ants, cockroaches, fleas, and other insects. The Outdoor Liquid Ant Baits are only made to kill ants. However, The Shaker Bag from Terro is a granule product and needs to be done by hand around your home, which is a lot more work than their Outdoor Liquid Ant Bait.
Terro Outdoor Liquid Ant Baits vs. Terro T2600Perimeter Ant Bait Plus
Terro Perimeter Ant Bait Plus is a granule that kills outdoor ants, cockroaches, crickets, earwigs, silverfish, slugs, and snails. While this perimeter ant bait eliminates more than just ants, it doesn’t work on all types of ants. Terro Outdoor Liquid Ant Baits work on the most stubborn ants, like Argentinian ants. Both products are weather-proof and long-lasting.
The Terro Outdoor Liquid Ant Bait Plus is a set-and-forget product meaning you can set the bait station up and leave it to do its work, taking care of all the ants without you worrying about reapplying until the liquid is gone. Terro Perimeter Ant Bait Plus needs to be placed around the outside of the house and reapplied. From customer reviews, it doesn’t seem to be an excellent long-term solution.
