It can be difficult to eliminate them because they form massive colonies and can hide from people.

Terro Ant Bait is a highly recommended product from one of the oldest pest control manufacturers in the industry. It kills many different species of ants and comes in convenient, no-spill cups so people can use them around their homes.

But is all of the hype about Terro true?

This review aims to find out!

Below is an in-depth product review which takes the pros and cons of Terro Ant Bait into consideration.

SECTION: 1 The Rating

Terro is a big name in the industry and manufactures a variety of products designed to capture and get rid of annoying ants. One of the most popular products is the liquid ant bait, which can be bought in packages with multiple stations.

The ant bait can be used indoors and outdoors and features a versatile design which doesn't leak. This product is useful for people who don't want to handle pesticides or need to have a trap that can be placed in multiple locations like cabinets, the garage, or the back patio.

But can Terro Ant Bait really eliminate the entire colony?

The main ingredient in the bait is boric acid, which is derived from borax. Borax is a pesticide approved by the EPA for general use and is a moderately toxic substance. It can kill entire colonies of ants within a week, but can take up to two weeks for maximum efficiency.

SECTION 3: The Key Features

So, why would you want to use Terro Ant Bait over other products?

Easy To Use

The instructions for Terro Ant Bait are extremely simple.

  1. Remove baiting stations from package.
  2. Place around home or yard.
  3. Pick up and dispose of stations when done.

The convenience of Terro is that there are no complicated procedures involved. See the below video for a demonstration of how the Terro ant bait works.

Flexible Implementation

Unlike some other ant baits and pesticides, the Terro bait can be placed inside or outside your property. The baiting stations won't be affected by the rain and are small enough to use in all of the corners of your home. The bait is also covered by a plastic sheath which is difficult for pets and children to get through.

You Don't Have To Handle Chemicals

A lot of ant baits on the market require you to handle pesticides, whether it's the poisoned granules themselves or toxic liquids. Terro features an ant bait which comes inside intact baiting stations. Ants can reach the attractive toxins, but it's difficult for you, your pets, and your family from touching them.

You should still keep pets and children away from the product and wash your hands after use, but you don't have to work with the raw chemicals yourself.

Fast-Acting Formula

Ants who ingest the bait will die within a few hours to a few days, but not before bringing the bait back to the colony. It can take one week for the majority of the colony to perish, and two weeks for the entire group to die.

People facing serious infestations can rest easy knowing that their problem will be partially alleviated almost immediately.

Effective On Different Ants

Terro Ant Bait specializes in the elimination of sweet-eating ants but can work on most species which enter a household. Common black ants, pavement ants, cornfield ants, and pharaoh ants are all affected by the product, as are a half dozen others that can annoy you and your family.


When evaluating products, we use five criteria:

  • Company Reputation
  • Active Ingredient
  • Easy Of Use
  • Pet and Child Safety Rating
  • Overall Effectiveness

Reputable Company/Customer Service:

The Woodstream Corporation owns the Terro brand and offers a broad range of pest control products for the general consumer.

Terro Liquid Ant Bait was first introduced in 1915 and is considered to be the "Gold Standard" when it comes to ant reduction and elimination.

Despite some of its negative feedback across consumer reviews, many MANY clients praise the company's customer service. If you have a problem with the Terro Ant Bait, you can conveniently contact a representative to discuss the problem and either receive a new product or a refund.

With how difficult it is to eliminate ants, it's helpful to receive aid from a business without further setbacks.

The company additionally performs the majority of its own research for the projects to ensure their safety and efficiency for consumers like you. 

Active Ingredient:

The active ingredient in Terro Ant Bait is boric acid, which is the derivative of the common borax. Boric acid is a highly effective pesticide which can eliminate many different types of pests, including ants, weeds, spiders, and mold.

Boric acid disrupts the stomachs of ants and can then target the nervous system, causing failure throughout the body. The granules can also scratch the ant's interior.

Humans should avoid all contact with boric acid granules because it can cause poisoning, seizures, and even death. However, the sealed baiting stations help lower the risks from coming into contact with the pesticide.

Finally, boric acid occurs naturally in the environment and is relatively harmless in small doses. Too much can kill plants, and the product is slightly toxic to freshwater fish, but most birds, fish, frogs, and even bees are unaffected.

Ease of Use:

As mentioned earlier, Terro Ant Bait is extremely easy to use and only requires unwrapping the packaging and placing the stations throughout the affected area. This feature is useful for people who don't want to handle pesticides or who don't want a complicated process.

Is This Pet and Child Safe?

The bait itself is not pet and child safe and should be kept away from curious hands and snouts. Terro uses baiting stations (the chemicals are inside a plastic container) which can help limit exposure and make it easier to use the pesticide throughout the house with minimal risks.

Overall Effectiveness:

Terro bait is effective against most ant types and works almost immediately to eliminate pesky pests. The product can take one to two weeks to wipe out a colony, but is versatile and comes with protective packaging.

SECTION 5: “How Does It Compare Against Competitors?”

  1. Harris Borax Liquid Ant Killer
  2. Maxforce Liquid Ant Bait Gel
  3. Advion Ant Bait

Terro Ant Bait vs. Harris Borax Liquid Ant Killer

Both of these products are already near the top of the pest control market because of their flexible use. The two ant baits are EPA-registered for indoor and outdoor use and can be placed almost anyway.

Terro and Harris additionally use similar ingredients because both borax or a borax-derivative to eliminate ants in an environmentally friendly manner. 

However, in terms of use, Harris Liquid Ant Killer poses one, serious extra risk when compared to Terro Ant Bait. The baiting stations are open and easily accessed by pets and children. Users pour the liquid into a clear station which is easy to tip over or spill.

People with young children or curious pets could be putting their loved ones at risk, so I would not recommend it to those groups.

Terro Ant Bait vs. Maxforce Ant Bait Gel

Terro and Maxforce developed baits which are effective against numerous types of ants, including pesky pharaoh and odorous house ants. Both products can be used indoors and come with baiting stations for flexible placement.

Unlike Terro, Maxforce does not have bait stations. Instead, you have a syringe of liquid that you'll need to apply the chemical to the affected area. This means that pets and children can easily access the toxin and could be poisoned.

This product can be beneficial for people who live alone or have older children, but I would not recommend it to individuals with pets and children.

Take a look below to see how you would deploy Maxforce Ant Bait.

Terro Ant Bait vs. Advion Ant Bait Gel

Both of these products can be used indoors or outdoors and feature powerful toxins that can eliminate an ant infestation fairly quickly.

Similar to Max Force, Advion also comes in a syringe and has to be applied to specific areas.

No products found.

Advion is great and has been knocking down ant colonies for a long time, but we simply like the convenience of the Terro Ant Baiting system. 

If you go with an Advion or a Max Force, you're either going to have to be okay with putting the chemicals directly into the surface ares around your home or shell out a little bit more money to buy baiting stations.

Also, liquid ant baits such as Advion and Max Force don't work as well when deployed outdoors, whereas Terro can be left just about anywhere.

To give you an idea of how this type of bait works, take a look below at the timelapse video of ants eating Advion bait on a widow.

SECTION 6: The Bottom Line

People with serious ant infestations should consider investing in Terro Ant Bait because it comes with its own stations and is carefully sealed to prevent human contact with the toxins.

The product works against numerous ant types, and the stations can be easily disposed of after use. Boric acid is also an environmentally friendly alternative to other pesticides and causes minimal damage.

Finally, the company who produces Terro remains trustworthy and reliable while also dedicating a large amount of time to customer service.

I highly recommend this product to people seeking an effective, relatively safe alternative to other liquid pesticides and ant baits.
