7 Best Ant Baits of 2019

If you have an ant problem, you need the best ant bait to get rid of your problem quickly. Bait lasts 24 to 48 hours, and these baits are slow to digest because the ant needs to be able to make it to the queen.

You can kill off any worker ant you want, even hundreds, but if the queen is not targeted, the colony will live on.

Bait is also just a small portion of an ant’s diet, so you may need to reapply the bait often to be able to kill off a colony.

We’ve done a lot of research and we believe that we have found the best ant bait on the market.

2. Best Indoor Ant Bait: Terro T300

TERRO 2 Liquid Ant killer

Terro has a lot of great products, many are on this list, and this is a cheap, easy solution for indoor use. I have used this ant bait to kill ants in my office, and it will attract ants from everywhere.

I had ants walking in a line that was hundreds of feet long to gather the bait.

It was an interesting experience, and initially, it will attract more ants than you’ll ever want to see in your home. But after a few days, the trail of ants will grow smaller and smaller until the point where there aren’t any ants left.

Bait stays fresh until opened, and it’s easy to use:

  • Open the bait
  • Place it where you see ants
  • Monitor your placement
  • Replace every three months as needed

Borax is used as the active ingredient, and it’s one of the best solutions to control ants. The trap is also clear, so you’ll be able to see ants going in and out of the bait station.

Pros
  • Works using Borax
  • Attracts ants you never knew existed
  • Lasts for months
Cons
  • Attracts an absurd amount of ants

My only complaint is that you’ll see dozens or hundreds of ants swarming the bait. It can be a startling process, and for me, I made the mistake of putting the bait on my office desk. I was watching ants all day for a few days, but then I also watched them start declining to the point that the infestation was completely gone.

 

3. Best Ant Bait Gel: Syngenta TRTD11568

Syngenta TRTD11568

Syngenta is another great company, and they offer ant bait in gel form. Gel is the ideal option when you have ants comes in from cracks and crevices. The active ingredient has been proven to kill:

  • Carpenter ants
  • Ghost ants
  • Fire ants
  • Harvester ants
  • Other ant species

What’s ideal about gel ant bait, this product in particular, comes with four tubes of gel and a plunger. You use the plunger to put the gel in cracks and crevices that ants use to come into the home.

Ants that are sneaking in from outdoors or from the walls of the home will eat the gel and bring the bait back to the queen ant.

Thiamethoxam is the active ingredient in this ant bait, and it has been approved for outdoor and indoor use. Brood, worker ants and queen ants will not be able to stand a chance – they’ll die.

Pros
  • Attractive formula that attracts ants
  • Thiamethoxam active ingredient
  • Syringe allows for easy application to crevices and cracks
Cons
  • Gel can dry and doesn’t work well if it gets wet

One complaint I do have, and you’ll see this with a lot of gel products, is that it will begin to dry over time. You’ll also notice that when applied outdoors, the bait seems to be far less effective if it rains.

But when ants are making their way into your home through cracks and crevices, gel is the best method to stop these ants in their tracks.

 

4. Terro Multi Surface Ant Baits

Terro Multi Surface Ant Baits

Terro’s multi surface ant baits come in one, two and five packs, but they’re different than the liquid ant bait that we reviewed prior. Sometimes, you do not want the world to know that you have an ant infestation.

Terro works wonders, and it’s discreet.

Two-color designs match most decor, and these are adhesive strips that you use for discreet baiting. All you need to do is attach the adhesive in a hard-to-see location, and ants will be attracted to it.

Ants will be attracted to the bait, carry it back to the rest of the colony, and kill the entire mound.

Stay-fresh tabs allow you to keep the bait good until it’s time to use it. You will want to keep the bait out of reach of pets and children.

Pros
  • Discreet adhesive
  • Kills most common ants
  • Two colors to match decor
Cons
  • Doesn’t kill carpenter ants

These adhesive strips will not kill carpenter ants or other hard-to-kill ants, but it will kill other common ants. Sleek and discreet, this is an effective ant trap that can be placed right on the wall or under a cabinet.

It’s the best way to kill ants without them crawling in front of all of your house guests.

 

5. Advance 375a Ant Bait

Advance 375a Ant Bait

Do you have hard-to-control ants? If so, Advance 375a has incorporated a variety of attractants into their formula to attract ants directly to their death. Ideal for outdoor use, this ant poison kills:

  • Fire ants
  • Pavement ants
  • Black ants
  • Field ants
  • Pharaoh ants
  • Crazy ants

And this is just the start of the different ant species that 375a Advance can kill. Using a protein-based bait, this formula is a delayed-action insecticide containing: Abamectin. You’ll want to place the bait around the exterior of the home so that the ants will come in contact with it and carry it back to their ant mound.

This ant bait can be used indoors or outdoors, but it’s best used outdoors and out of reach of pets and children.

Pros
  • Designed to eliminate difficult-to-kill ants
  • Multiple attractants attract ants of all species
  • Kills ants quickly
Cons
  • Often leads ants indoors

It’s funny, but there are times when the bait is so effective that the ants are lead back indoors. You’ll want to make sure that when using this bait, you use an indoor bait, too. Ants are very smart, and they will be able to detect the best ant bait and actually avoid it.

 

6. Ortho Fire Ant Killer

Ortho Orthene Ant Killer

Ortho’s 12-ounce fire ant killer is able to treat up to 162 ant mounds. Hundreds of thousands of ants can be killed with a single bottle. The mound, worker ants and queen will die.

There’s no watering-in required, and the product is guaranteed to kill or you’ll get your money back.

You’ll want to treat mounds as they appear, and it’s best to treat when it’s 65 – 90 degrees outside. A two-action formula does two things:

  • Kill the mound
  • Protect the ground

But keep in mind that this product is designed to kill fire ants. Fire ants are very resilient, and if it kills fire ants, it will kill other pests. Consumers have had success with killing roaches, crawdads and other insects with this bait.

Pros
  • Offers dual protection for all of your ant-killing needs
  • Kills fire ants and roaches with ease (other insects, too)
  • Works very quickly
Cons
  • Smells horrible

You’ll want to be very cautious when placing this ant bait outside of your home. A lot of people put the bait outside of their windows, but the smell is overpowering. The strong smell can permeate into the home, which no one wants.

But this ant bait is an effective killer and will quickly get your ant infestation under control.

 

7. Terro 1806 Outdoor Ant Bait

Terro Outdoor Liquid Ant Baits

Terro has a new product that I wanted to review because it’s similar to the liquid ant bait that I reviewed previously. But this product is specifically designed for outdoor use. The product comes in a six-pack, so that’s more than enough bait stations to place outdoors.

Baiting outdoors works, and one ounce is included in each product. Safe around pet and kids, the active ingredient is borax.

All you do is place the stakes out, give it a twist and stake the bait station to the soil. Simply place these products against the exterior wall of the home. You can also hide them behind bushes so that they offer a discreet method of ant control.

Attracts all common species of house ants.

Pros
  • Stakes keep the ant bait from flying away
  • Fits nice and snug against the exterior wall of the home
  • Contains borax and is safe for animals
Cons
  • Attracts racoons and opossums

I have read that a lot of people have their ant bait traps stolen or the liquid drained out of the trap by various pests. Racoons and opossums seem to be the biggest culprit, but as an outdoor ant bait, it’s something that you need to expect.

Terro has done a wonderful job with the 1806, and with the addition of stakes, this may be my best choice for a discreet outdoor ant killer.

 

Ant Bait Buying FAQs

When Should You Use Ant Bait?
What’s great is that you’ll find indoor and outdoor ant baits. The best ant baits may include gels, granules or other forms of bait that work to attract ants. Often using a sweetener, these ant baits will attract the ant to eat it and then bring the bait back to the queen.

Sometimes the ant will not make it back to the queen, but given enough time, a worker ant will reach the queen.

And since the queen is the one that is responsible for laying eggs, once she is dead, the colony will soon die.

You’ll want to use ant bait when you:

  • See an ant mound in your yard
  • See multiple ants in the home (dozens)

If you see one or two ants roaming about, there’s really no need to use a spray, bait or gel.

Can You Use Ant Bait Indoors?
Yes, but you need to find an insect bait that mentions that it’s for indoor use. There are some baits for ants that are meant only for outdoor use.
Are Dogs or Cats in Danger of Ant Bait?
Yes. If you have animals or small children, you’ll want to ensure that they’re kept away from any ant bait that you use. While the animals may not die from the substance, smaller animals definitely can.

The insecticides or poison within the ant bait are not safe for consumption.

It’s important to either keep your dog out of the room where the bait is located, or keep them out of the yard when the bait is present. Otherwise, you never know if your animal will have a reaction to the bait or even die.

If you have to place the bait in your yard, I recommend reading through our guide on how to get rid of ants outside.

How Long Does Ant Bait Last?
Bait may last a day or weeks – it depends. Gels, for example, may work until they become wet or dry. A lot of different gel ant baits will dry out and become far less effective in the process.

Outdoor granules will often be less effective or stop working completely when it rains.

But some forms of bait can last up to three months. If you look at the instructions on the ant bait, you’ll find that the duration of the bait will be listed.

If you’re wondering how long the ant bait will last inside of the ant’s system, this will also vary. You’ll find certain types of ant bait to be far more effective and deadly than others. There are also some ants that seem to be more durable than others.

What I mean is that some ants will die rapidly, but most ants will die within 24 to 48 hours of consuming the ant bait.

Will Ant Bait Work on Every Ant?
No, not all types of ants will be able to be killed with ant bait. Average ants will die when they take the bait and will be successfully eradicated with bait. But with over 10,000 species of ants, some ants will be more resilient to the bait than others.

Bait effectiveness will also differ from one bait to another.

If you have fire ants or carpenter ants, you’ll want to buy bait that is specifically designed to kill them. Fire ants are especially difficult to kill, and since they have stingers, they’re often the first ant species that you’ll want to remove from your yard.

Bait must be slow-acting to be able to allow for time for the ant to get back to the colony.

You also have to consider that ants eat a variety of food. Ants may flock to bait on some occasions, but the bait is just a small portion of the ant’s complete diet.

Should I Use Ant Bait With Traps?
The words bait and traps are often used interchangeably. But there are traps that ants will enter and granules or gel forms of bait that ants will consume. I recommend using granules for outdoor use.

Indoors, you’ll want to use traps and also gel.

Why?

Traps or bait stations can be placed in areas where ants traverse most often. Gels or pastes can be applied to cracks and crevices in the home. You want to take a whole home approach to ant control if you really want to rid yourself of ants.

By ensuring that your yard and indoors are both treated properly, you’ll kill ant mounds outside and also ant mounds that may have been made in areas that you don’t expect. Some people claim to have ants in their walls, and using paste or a trap is the best solution – you can’t easily get inside of your home’s walls.
