When an ant infestation hits your home or yard, it’s natural to look for quick and easy solutions. One remedy that has been circulating for some time now is the use of grits – yes, the type you might have for breakfast – to control or even kill ants. This intriguing idea could seem like a simple and affordable solution to your ant problem, but does it work? Settle in as we debunk the myth, explain the science, and provide you with effective strategies to tackle an ant infestation.

  • Grits, a food made from ground, dried corn, does not kill or harm ants. The myth that grits can lead to the death of ants by causing them to burst when digested is not accurate as adult ants can’t digest solid food, including grits.
  • Ants, when they encounter grits, perceive this substance as a barrier rather than food. They can walk around or over the grains but will not ingest them.
  • Although grits alone aren’t effective in handling ant infestations, they can help in different ways when combined with other strategies. They can act as a bait carrier to deliver ant-killing substances or a deterrent to repel the ants. They can also help in tracing ant routes to identify their origins or the regions they infest.
  • Killing ants and managing their infestations require methods like commercial ant baits, insecticides, sealing off potential entry points, and maintaining cleanliness in your home. It might also be necessary to seek professional help from pest control services when the situation becomes unmanageable.
  • Ant infestations should be handled with care, considering the safety of the pets and the entire household. Some substances or chemicals used to control ants might be harmful to human beings or pets, so it’s best to always read labels and ask experts when in doubt.

What is the Efficacy of Grits on Ants?

What is grits and how is it commonly used?

Grits is a common food in the American South, made from ground, dried corn. Traditionally boiled and served with butter for breakfast, they provide a filling start to the day. Grits’ rough texture and absorbent nature led to the myth that they could play a role in pest control, specifically ants.

How does grits affect ants?

Contrary to popular belief, grits don’t have a harmful effect on ants. The myth proposes that when an ant eats grits, the grains would expand in their stomach, causing the ant to burst. This couldn’t be further from the truth, as ant physiology doesn’t allow digestion of solid food like grits.

Does grits kill ants?

Simply put, no. Grits do not kill ants. This is a common misconception based on the faulty understanding of ant anatomy and dietary habits.

Will instant grits kill ants?

Even instant grits won’t lethal to ants because ants cannot eat or digest this solid substance in its original state.

How did the myth originate?

The myth that grits can kill ants probably arose from the pest control industry. Some ant bait products use corn grits as a carrier of insecticide. Misunderstanding might have led to people believing that it was the grit itself, not the poison it carried, that killed the ants.

What happens when ants encounter grits?

From the ants’ perspective, grits are not food but rather a barrier. When they encounter grits, they may walk around or over the grains but will not consume them. Any ants dying near a pile of grits would likely be coincidental, not a result of eating the grits.

Understanding Ant Physiology and Diet

What is the scientific explanation that debunks the myth that grits can kill ants?

Ant physiology defies the myth that they can die from consuming grits. Adult ants cannot digest solid food, instead, they ingest liquids, primarily from fruits, nectar, or honeydew produced by aphids.

How do ants digest food?

When ants find solid food, such as bread crumbs or grits, they carry it back to their colony instead of eating it directly. The juvenile ants – or larvae – are able to digest solid food and convert it into a nutrient-rich liquid. This liquid is then shared with the adult ants in the colony.

Why can’t ants digest solid foods?

Ants cannot digest solid food because of their unique digestive system. Adult ants have a narrow passage in the middle of their bodies called the “waste canal” that only allows for liquids to pass through. So, it doesn’t matter in what form the food is initially found, it must be converted into a liquid before adult ants can digest it. This is the job of the larvae, who take solid food, break it down and convert it into a liquid that can be shared with the rest of the colony. Therefore, anything solid—including grits or other grainy substances—simply can’t be digested by adult ants.

Why can’t grits alone eliminate ant colonies?

Grits cannot eliminate ant colonies because even if the ants bring the grits back to the colony, the larvae will process it, turning it into a digestible liquid form. No ant will consume whole grits that could potentially expand and kill them. Therefore, ants are not threatened by grits alone.

Does Grits Kill Various Types of Ants?

Does grits kill fire ants?

No, grits do not kill fire ants. While fire ants are notorious for their painful stings and aggressive nature, using grits as a means to control or eliminate them is ineffective. Even though they might carry the grits back to their colony, the grits will not harm the ants.

Do grits kill black ants?

Just like fire ants, black ants won’t be harmed by grits either. Black ants, like all ant species, have physiology and digestion systems that enable them to handle solid foods like grits without any adverse effects.

Does grits kill sugar ants?

Grits won’t kill sugar ants or any other species of ants. Sugar ants, named for their attraction to sweet foods, still won’t be able to ingest solid foods like grits. They will carry it back to their colony, where it will be processed into liquid form for consumption.

Does grits kill red ants?

Contrary to the myth, grits do not kill red ants. Red ants, like other ant species, only consume liquids and cannot eat or process solid foods like grits that would swell up and harm them.

Could Grits Serve Any Role in Ant Control?

Can grits act as an attractant or carrier for ant poisons?

While grits alone don’t harm ants, they can act as a carrier for insecticides or ant baits. Ants are attracted to the carbohydrate-rich grits and will carry tainted grains back to their colony. However, it is essential to understand that it is the poison, not the grits, causing harm to the ants.

Is there any other ways grits could be used to control ants?

While grits alone are not an effective method for killing ants, there are several alternative strategies that involve grits and may potentially impact ant behavior. However, it’s important to realize that the effectiveness of most of these methods is questionable:

Grits as a Bait Carrier

You can use grits as a medium to carry other ant-killing substances, such as boric acid. In such cases, it would be the added substance, not the grits themselves, that has the euthanizing effect on the ants.

Grits as a Deterrent

Though ineffective at killing ants, scattering grits around areas you want to protect from ants may deter them from entering these spaces. This is likely to offer a only temporary respite from the ants.

Tracking Ant Movements

Grits, or any other granular foodstuff, can potentially be used to trace the routes of ants, helping you determine their origins or destinations. This can be beneficial when deciding on the most effective locations to place other ant control measures.

Combination with Other Methods

Some individuals choose to combine the use of grits with other ant control methods, under the assumption that the ants might be more attracted to the grit-containing areas and hence come into contact with other ant-killing substances.

Feeding Birds

While not directly related to ant control, scattering grits may attract birds, which could help with broader insect control. However, this could also attract other harmful or unwanted animals to your property, so proceed with caution.

If your primary focus is on finding non-toxic methods for controlling ants, it’s worth considering proven alternatives such as diatomaceous earth, boiling water, or commercial ant control products specifically labeled as safe for pets and livestock. Always remember to carefully read labels and consult with pest control experts if you have any doubts or concerns.

What Are Effective Methods to Kill Ants?

How do you kill fire ants?

Effective ways to kill fire ants include using baited insecticides or contacting professional pest control services. These treatments contain toxins that the worker ants will carry back to the colony, sharing with the rest of the ants, eventually leading to their elimination.

What are some fire ant killers safe for chickens?

As a chicken owner, dealing with pests such as fire ants necessitates caution. Below are methods safe for chickens:

Mechanical Methods:

  • Boiling Water: Pouring boiling water over the mound is a non-toxic way to kill ants on contact. It might require several applications.
  • Digging: Manually removing the mound and ants provides a physical solution. This method is labor-intensive and might lead to the ants merely relocating their mound.

Organic and Natural Chemicals:

  • Diatomaceous Earth: Food-grade diatomaceous earth is safe for chickens and can treat ant mounds effectively. However, its effectiveness diminishes when it gets wet.
  • Boric Acid Baits: These are safe if used cautiously and kept out of reach from the chicken. Ants take the bait back to the colony, impacting the entire group.
  • Lemon Juice and Water: A mixture of lemon juice and water can disrupt the ants’ tracking senses, but it often serves as a temporary solution.
  • Neem Oil: An organic solution that deters ants and remains safe for chickens.
  • Organic Sprays: You can use commercially available, organic ant killer sprays made from plant oils like peppermint and rosemary. Always check the label to ensure they’re safe for chickens.
  • Vinegar: Spraying a water and vinegar mixture on ant mounds can disrupt ant activities. Beware, vinegar can harm plants, so spray cautiously.
  • Spices and Herbs: Scattering spices like cinnamon, cayenne pepper, or garlic around the mound can deter ants. While not a permanent solution, it’s safe for chickens.


  • Always Read Labels: Even products labeled as ‘natural’ or ‘organic’ can sometimes contain harmful ingredients for chickens.
  • Test Small Areas First: Before applying any substance over a large area, test it on a small scale to ensure effectiveness and safety for your chickens.
  • Consult a Vet: When in doubt, it’s best to consult a veterinarian for advice tailored to your specific situation.
  • Monitor Chickens: After implementing any treatment, closely observe your chickens for any signs of distress or poisoning.
  • Keep Chickens Away Temporarily: For certain treatments, it might be best to restrict chicken access to treated areas until no harmful residues remain.

Does boiling water kill fire ants?

Pouring boiling water into an ant mound can kill many of the ants and disturb their colony, but it may not kill the queen. Moreover, this method can be dangerous to the person pouring the water and harmful to the surrounding vegetation.

Is magnesium citrate effective against ants?

Research shows that a dilute solution of magnesium citrate can be effective at killing certain types of ants when they ingest it. However, for a broad and effective control of an ant infestation, commercial ant baits and insecticides are generally the best solution.

Is there a red ant bait?

Yes, there are commercially available ant baits specifically designed to attract and kill red fire ants. These baits often contain a slow-acting insecticide mixed with foods that attract fire ants. The ants pick up the bait and take it back to the colony where it’s shared, leading to broader control over an infestation.

How to Deal with Fire Ant Mounds Specifically?

How to kill a fire ant mound?

There are a few effective ways to kill a fire ant mound:

  • Insecticide: Use a product specifically branded for fire ant mounds. Follow the instructions on the package for best results.
  • Drenching: A hot water or insecticide drench can be used to flood the mound. This method is particularly effective but requires caution due to the danger of boiling water or potent chemicals.
  • Baits: Apply targeted fire ant baits around the perimeter of the mound. The worker ants will carry the bait back to the colony, effectively distributing the insecticide. Baits usually take some time to show results but are relatively low-effort.
  • Professional Pest Control: If all else fails, or the infestation is overbearing, enlist the help of a professional pest control service. They have access to commercial-grade products and the expertise to eliminate fire ant colonies effectively.

How to get rid of fire ant mounds?

Getting rid of fire ant mounds requires a combination of integrated pest management strategies:

  • Baiting: Apply ant bait around mounds. Worker ants will carry the bait into the mound to share, killing unseen ants including the queen.
  • Mound Treatment: Treat individual mounds by drenching them with an approved insecticide for immediate results.
  • Preventive Treatment: Use approved long-lasting insecticides to treat your entire home perimeter to prevent new mounds from forming.
  • Yearly Professional Inspection: Regularly scheduled inspections by pest control professionals ensure you get rid of mounds as soon as they form.

How does a fire ant killer work on mounds?

Fire ant killer usually contains a slow-acting poison which worker ants carry back to the colony. The worker ants share this poison as food with the queen and other ants in the colony. Given enough time, the poison will kill all the ants, including the queen, effectively disrupting the colony’s life cycle and causing their eradication.

Can Chickens Help Control Fire Ants?

Will chickens eat fire ants?

Chickens will eat many types of insects, including fire ants. They scratch around to seek out insects as a part of a natural diet. However, fire ants can sting and cause harm to chickens especially young ones. So, relying on your chickens to completely manage a dangerous fire ant population might not be effective or safe for the chickens.

What happens if chickens eat ant poison?

If chickens ingest ant poison, it can cause health issues ranging from minor to severe. Chickens can experience symptoms such as loss of appetite, reduced egg production, weight loss, weakness, or even death. Therefore, always use ant poison with caution around chickens and ensure they do not have access to it.

Is Grits a Safe Solution for Ant Control?

How safe is grits as a method to kill ants for humans and pets?

Using grits to try to control ants is safe for humans and pets. However, the real issue is that it is not effective. Ants are not capable of ingesting solid foods like grits, and even if they were, the grits alone would not kill them.

What are the potential drawbacks of using grits to kill ants?

The primary drawback of using grits to kill ants is, simply, that it won’t. While it is safe for use around humans and pets, it is ineffective. Misinformation can lead homeowners to believe they are addressing their ant issues when, in reality, the infestation continues to grow.

How Effective Is Grits Against Ants?

How effective is grits for killing ants?

Using grits for killing ants is not effective at all. Ants can’t eat grits, and therefore they can’t be harmed by it. The common misconception that ants can eat grits, which then swell and cause the ants to burst, is a myth.

How does grits compare to other commercial ant killers?

Grits pale in comparison to commercial ant killers when it comes to efficacy. Commercial ant killers contain ingredients specifically designed to attract and poison ants, leading to the elimination of the colony. Grits, on the other hand, can’t even be consumed by ants, let alone cause harm to them.

Does grits kill ants instantly?

No, grits do not kill ants instantly, or even over a period of time. Ants physically can’t eat grits, so it’s impossible for them to succumb to this grain.

Can grits completely eradicate an ant infestation?

Grits alone cannot eradicate an ant infestation because they can’t harm the ants. To effectively control an ant infestation, it’s best to use proven pest control methods, such as bait traps, insecticides, or professional pest control services.

Is grits a long-term solution for ant infestation?

No, grits are not a long-term solution for ant infestation. While they are safe to use around pets and humans, they have no impact on ant colonies. For a long term solution, consider proven methods such as commercial ant baits, professional pest control services, or natural solutions like diatomaceous earth.

How can I use grits to kill ants effectively?

As has been discussed, you can’t use grits alone to effectively kill ants. However, you can use grits as a carrier for other ant-killing substances. For example, you could mix grits with boric acid, a known ant killer. The ants will be attracted to the grits, carrying them back to their colony, and thereby spreading the boric acid.

How to Prevent Future Ant Infestations?

Can I use grits to control ants before rain?

No, using grits before rain will not control ants. Ants are largely unaffected by grits, with rain or without, so this wouldn’t be an effective method of ant control.

How to keep fire ants away?

To keep fire ants away, consider these preventative measures:

  • Regularly inspect your home and yard for signs of ant hills and treat them promptly.
  • Seal entry points into your home to prevent ants from getting inside.
  • Maintain a clean and tidy house, especially in the kitchen and dining areas where ants are attracted to food crumbs.
  • Regularly use commercial bait traps as a preventative measure.

How can you differentiate between fire ant mounds and regular ant mounds?

Fire ant mounds typically appear as large, irregularly shaped piles of dirt with no clear entrance hole on top. They can pop up anywhere, but are often found in sunny, open areas like lawns. Regular ant mounds, on the other hand, tend to be smaller with a single, clear entry point.

What are the proven methods to kill or control ants?

The most effective methods to control ants include:

  • Using commercial ant baits and insecticides.
  • Sealing off potential entry points into your home.
  • Keeping your home clean, especially in areas where food is prepared or consumed.
  • Enlisting the professional help of pest control services.


While a simple home solution would be ideal, grits alone are not effective for killing or deterring ants. Understanding the biological makeup and eating habits of ants can help dispel myths and inform you about how to effectively handle these pests. If facing an ant infestation, your best course of action is to use commercial ant killers or seek professional pest control help. Always remember to consider the safety of your pets and environment before choosing any form of pest control.
