Natural Indoor Ant Treatment — Diatomaceous Earth

Natural Indoor Ant Treatment

Ants are one of the most common insects that invade the home. Depending on the climate, they can be anything from an occasional nuisance to a persistent pest. Being such a regular home visitor, there are many products devised to take care of them; so why use an organic ant control? Natural products like diatomaceous earth will be safe to use around your kids and pets. DE will continue to work long after any chemical products’ effect have dissipated, providing a natural ant repellent as long as the powder remains.

For instructions on how to use DE in your home to combat ants, follow the steps below.

You will need:

  • Crawling Insect Control Diatomaceous Earth
  • An Applicator like this one for wet applications or this one for dry applications

Step 1:

Find areas around your house where you have seen ants crawling. Mark places where you think and may be able to enter your house. If ants have been moving across a large flat area, or have been moving up walls, you may want to use a wet application. If the ants have been moving along edges and cracks, baseboards and floorboards, or are working their way along window sills, you may want a dry application.

Step 2:

Apply diatomaceous earth. You can use a duster to target along edges, behind baseboards, and any other hard to reach places. Alternatively you can use a flour sifter to lightly dust larger problem areas. Also take time to target parts of your windows and doors which you find susceptible.

Step 3:

Watch the areas you have treated and take note of alternate routes taken by ants to see if any follow up applications are needed. After a month, clean off the areas where you have applied DE and reapply. Pay particular attention to the areas where ants can get into your house to prevent future ant trails

If the ants have been moving along edges and cracks, baseboards and floorboards, or are working their way along window sills, you may want a dry application.

Step 2:

Follow the instructions for application listed here. Use the spray bottle to target larger areas such as walls, where you have seen ants travelling. This type of application is not good for small nooks and crannies. DE will not work while it is wet but only after the water evaporates will it take effect. Keep that in consideration as you make your applications.

Step 3:

Watch the areas where you have sprayed, take note of alternate routes taken by ants and treat accordingly. After a month, clean off the areas where you have applied DE and reapply. Pay particular attention to the areas where ants can get into your house to prevent future ant trails

Using Borax Powder to Kill Ants

Whether they’ve found their way into your home after a heavy rain or because you missed cleaning up a few crumbs on the counter, ants are a pest that seem to immediately take over your home when they find a way inside. When you discover ants in your home, you want them gone right away. While you’ll find several ways to kill ants, if you’re looking for an effective solution, consider using borax.

The Difference Between Boric Acid and Borax

Although they’re both used as a pesticide, boric acid and borax do have some differences. Borax is a mineral mined from the ground. You can find it in cosmetics, toothpastes, soaps, weed killers, and it’s most often used as an alternative to harsh laundry detergents. After further processing, borax turns into boric acid. Whether you have borax or boric acid, it’s important to remember that you need to keep these products away from children and pets. Additionally, be careful when you’re using it because it might cause skin irritation.

Why Is Borax Lethal to Ants?

Although borax has a low toxicity rate for humans and other animals, it’s fatal for ants when they come in contact with it. When ants eat the borax bait, it interferes with their digestive system and eventually kills them. However, it’s not an immediate death. That’s because, for effective ant control, you need to eliminate the queen and the rest of the colony. Worker ants will consume the borax bait and bring it back to the colony for the other ants to eat.

Using Borax to Kill Ants

It’s important to keep in mind that if you’re thinking about using borax powder, ants aren’t attracted to it alone. In order to entice them to bring it back to the colony, you have to mix the borax with some of their favorite foods. The first step is figuring out where the ants are entering your home. The easiest way to find their entrance is to simply follow the trail of ants.

When ants find food, they leave behind a pheromone trail so that other ants in their colony can immediately locate the same food and bring it back to the nest. These trails are an ideal place to put your borax bait, but it’s even better if you can place the bait right in their entryway. That way, they’re not even coming inside your home.

Making Borax Ant Bait

Since all ants’ digestive systems work the same way no matter what species you’re dealing with, borax is an effective killer whether you have sugar ants, fire ants, carpenter ants, or almost any other type of ant in your home. The important thing to keep in mind is that you need a variety of liquid and solid baits.

Although it seems like ants will eat anything in sight, adult ants can’t digest solid foods and only eat liquids. On the other hand, larvae can process solid foods and turn it into a liquid that the queen will then eat. A variety of baits will make sure you eliminate the entire colony.

Liquid Borax Ant Bait Recipes

You’ll find several types of liquid borax ant bait recipes, so it helps to try out different options to see which one works better for the species of ant you’re dealing with. No matter which recipe you use, you’ll need some type of container to hold the bait. You can use a small plastic container, plastic lid, paper plate, or cotton ball. The only important part is to make sure the ants can easily get in and out of your bait holder.

One recipe you can try calls for a half cup of sugar, 1.5 tablespoons of borax, and 1.5 cups of warm water. Simply mix all the ingredients together until they’re blended, and place the bait in the trap for the ants to consume.

Another recipe to try, calls for three parts sugar for every one part borax. For example, if you use 1 cup of sugar you’ll need to mix it with one-third cup of borax. Blend these two ingredients together until you have no more lumps. Next, add enough water to turn the mixture into a thick paste. For the above example, about one-quarter cup of water will suffice. Finally, add about one-quarter cup of syrup to the mixture for a thick, sticky substance the ants can’t resist.

Solid Borax Ant Bait Recipe

For the solid borax ant recipe, you want to use the same 1-to-3 ratio mentioned in the liquid ant bait recipe. However, in this case, you’ll want to mix the borax with powdered sugar. As an example, if you use three-quarters of a cup of powdered sugar, you’ll want to combine it with one-quarter of a cup of borax. Then simply stir the ingredients together to make sure they’re completely mixed.

You can use the solid and liquids baits inside and outside, but if you use them in your garden, you need to make sure you put the mixture in a lid or other type of plastic container. Borax is also an herbicide, and it can kill your plants if you pour the mixture directly over them.

Using Borax to Kill Fire Ants

Fire ants are an invasive species that can cause plenty of issues if they decide to create a nest in your yard. Luckily, borax also effectively kills these colonies. Just keep in mind that you want to try to kill just the fire ants and not any indigenous ants. This is because if you kill every ant in your yard, you’re only leaving room for more fire ants to move in and take over the area.

Sparing the indigenous ants will help keep the ecosystem balanced. The easiest way to focus your borax baits for just fire ant consumption is to get a container of bait as close to the fire ant mound as safely possible. Then let the worker ants take care of the rest.

If you find ants in your home or yard, you now know how you can use borax to make liquid and solid baits to attract ants and ultimately kill the colony.

How to Use Sevin to Kill Ants

Things You’ll Need


Sevin also kills beneficial insects, such as honeybees. Try to avoid applying the powder to flower plants. If you must apply Sevin, dust the plant in the evening when honeybees are not active.

Sevin is a carbaryl-based insecticide created by the Bayer Company. The powder is used widely for outdoor pest control, and is especially effective against ants in your yard. Though some ants are beneficial, an excessively large ant population can kill your garden plants. Some types, such as fire ants, may even cause physical discomfort to humans. Use Sevin dust to kill ants to protect both you and your garden.

Step 1

Put on protective gloves and a face mask to guard against touching and inhaling the Sevin product.

Step 2

Scatter one to two tbsp. of Sevin dust evenly around the entrance to ant burrows and nests in the ground. The ants will walk through the powder and die. Some ants will also carry the product within the nest, poisoning the entire ant population.

Step 3

Dust a thin layer of the Sevin product in a two-foot radius around the ant burrows, in case the ants attempt to create new tunnels away from the main, treated burrow.

Step 4

Sprinkle Sevin dust around the base of plants that are being affected by ants. This forces the ants to walk through the insecticide as they climb on and off the plant. A light dusting directly on the plant can also help kill ants that are congregating on its foliage and branches.

Step 5

Treat the foundation of your home with Sevin if you have a problem with ants indoors. Though Sevin is intended for outdoor use, applying it to your home’s outdoor foundation can drastically reduce the indoor ant population and prevent future infestations. Dust the Sevin powder around your foundation where it comes in contact with the ground.

Will Diazinon Kill Ants?

Diazinon used to be the most popular lawn and garden pesticide on the market and was commonly used as against ants. About 13 million pounds of diazinon was sold annually, about 80 percent of that for residential use. Between 2000 and 2005, it was taken off the market for consumers and limited only to use by professionals in certain situations.

About Diazinon

Diazinon is a liquid, contact insecticide that kills by targeting the nervous system. It is non-systematic, in that it does not move inside a plant after it is absorbed. It is used in agriculture on vegetable, fruit and nut crops to control pests like moths, borers, mites, aphids and scale. While diazinon is still labeled for use against ants, it can only be sold to and used by certified applicators. Diazinon can be used as a barrier spray or to drench nests.

Legal History

The U.S. Environmental Protection Agency (EPA) announced in 2000 that all residential uses of diazinon would be canceled. Indoor uses were stopped in 2002 and outdoor uses in 2004. As of December 31, 2004, it is illegal to sell diazinon for any outdoor, non-agricultural use. It is not illegal for consumers to use diazinon products they may already own if they follow all label directions and precautions. However, it cannot be used on sod farms or golf courses because of its high toxicity to birds.

Environmental Effects

Diazinon is extremely poisonous to wildlife. One granule contains enough poison to kill a small bird. In 2005, it was the most commonly found contaminant in the air, rain and water, according to the 2005 «Los Angeles Times» article «EPA Takes Pest Killer Diazinon Off the Shelves.» The EPA found it poses a human health risk, especially to children. Although the EPA has classified it as «Class D» or non-carcinogenic, diazinon has been linked to childhood cancers and non-Hodgkin’s lymphoma, according to the U.S. Department of Health and Human Services.

Using Diazinon

While diazinon can be used against ants and will kill ants, there is no reason to use it. Alternative insecticides like pyrethoids, fipronil, chlorfenapyr, and thiamethoxam are just as effective as diazinon and not as toxic to wildlife. These chemicals are available in a variety of different ant killers on the market and will kill ants within a few minutes or a few hours, depending on the type of ant and insecticide.

How Long Does Terro Ant Bait Take to Kill Ants?

Terro Liquid Ant Bait is a sweet liquid containing sodium tetraborate decahydrate, better known as borax. The bait kills individual ants within 48 hours after they consume it. During that time, an exposed ant carries the bait back to the nest and spreads it to other ants, killing them as well. Large nests may take several weeks to completely eradicate.

Types of Ants It Kills

Terro ant bait is formulated for sweet-eating ants, including Argentine ants, acrobat ants, big-headed ants, cornfield ants, crazy ants, ghost ants, little black ants, odorous house ants, pavement ants, pharaoh ants and white-footed ants. Some species, particularly Argentine ants and pharaoh ants, are difficult to eradicate completely with baits because of their extremely large colony size. Terro Perimeter Ant Bait Plus is formulated for carpenter ant control in addition to the sweet-eating ants mentioned above.

Why It Works

Terro ant bait relies on colony behavior for its effectiveness. Ant colonies consist of one or more queen ants, who lay hundreds or even thousands of eggs, but never leave the nest. Worker ants take care of the developing eggs, while other workers forage for food and bring it back to the queens and nursery workers. Ant bait smells like food, but contains poison. Workers find it and bring it back to the nest before the poison kills them.

How It Kills the Nest

The borax in Terro ant bait is an acid that damages ants’ digestive systems and weakens their exoskeletons when it sticks to the tiny hairs on their legs. Worker ants, mistaking it for food, feed it to other workers in the nest and, more importantly, to the queen. Once the queen in a colony is poisoned and dies, she can no longer lay eggs to replace the workers, which are also dying of the poison. The colony eventually collapses.

When to Stop Offering the Bait

A small ant colony may succumb to Terro ant bait in a couple of days, while a colony numbering in the hundreds of thousands may take weeks to collapse. As long as ants are coming to the bait station, the colony is still at least partly functional and you should keep the bait station stocked with fresh ant bait. When no ants visit for several days in a row, you can remove the bait station. Be ready to replace it immediately whenever ants return.

5 Most effective ways to kill Ants Naturally

There are thousands of types of ants found on our planet but do you know only few of these species enter our homes to feed themselves and their queen who is living far away in a colony.

Not all of the people know that it is possible to kill ants with natural ways using some of the common ingredients available at home.

Ants bear a determined attitude and are not at all easily molded in their missions. This sometimes frustrates you and prompts you to use easily available toxic aerosols available in market under-estimating its harmful effects on humans as well as our environment.

There is numerous numbers of natural options available in our house, kitchen to be more specific, that can either repel them or destroy them. Moreover these natural methods are pocket-friendly too.

Let us explore some of these spices or ingredients and how one can make use of them to get rid of ants.


Does it kill ants? The answer is No. It does not kill ants but without any doubts, vinegar is a great repellant. You can either use it as spray or as a solution.

Just apply vinegar at all the suspected entry points to break the trail created by ants. You can also put some vinegar in water used for mopping floors of house.

Regular use will surely deter their invasion. For outside use, take care of following instructions.

  • Look for fire-ant mounds in garden area of your house. Spray a mixture of vinegar and water (2:1 ratio) on ant mounds to get rid of them.
  • Try to increase the concentration of vinegar if earlier mixture is little effective since some ants are more stubborn than others.

“Take care of the plants around the mounds as they may get damaged from the vinegar solution.”

Baking Soda

Baking soda is easily available ingredient in kitchen. You can make effective bait by mixing baking soda and sugar in 1:1 ratio. Sugar in the bait will pull ants towards mixture whereas baking soda will exterminate them.


Bleach is cleaning agent and is often found in cleaning detergents and cleaning liquid soaps. It is found to be effective in killing pests including ants. You can use it in any of the following ways.

  • Take any spray bottle and pour bleach solution in it and spray on the corners of the walls of kitchen and on sides of windows. It will not only reduce the aroma of food from the kitchen but will also act as a deterrent to their trail.
  • Take bleach solution in a bucket and clean counters and floors of kitchen with mop.
  • If you are lucky enough to find their nest, mix bleach in hot water and pour it over their colony to destroy them.

“Bleach has a bitter smell and after applying it inside house or kitchen. It is advised to keen windows open for some time.”

Corn Meal

Ants like to feed on cornmeal without knowing the fact that cornmeal once consumed is hard to digest for them. Ants carry cornmeal to their colonies; they feast on cornmeal and eventually cornmeal act as tiny bombs and explode these tiny ants.

Boric Acid

Boric acid is a poisonous substance so it is advisable to keep it away from children, but not from ants since it is quite effective in killing ants.

Mix Boric acid with grounded sugar and make tiny balls out of them. Place at all the entry points and other crawling areas.

To prepare an effective and successful bait, you should know the feeding habits of ants whether they like sugary substance or greasy like peanut butter.

Nobody at home is from biological expert to determine the species of ants so always try hit and trial method .Try maxing boric acid with sugar, jam or honey and see whichever works better.

Place the prepared bait on some cardboard at suspected crawling places and change the bait solution after few days to maintain its effectiveness.

Other way to use boric acid powder is to sprinkle this powder around their nest, any ant coming out of nest when gets contacted with boric acid,

will die instantly because of its concentrated form. Apart from sprinkling around nest, you can sprinkle it directly at entry points also.

If we compare sprinkling with baiting, sprinkling does kill the ants instantly but only those who gets contacted with boric acid powder, while bait,

being low in concentration of boric acid allows the ants to take it to their colonies and eventually letting their queen die after consuming it.


Finally, as we have learnt from this article how effective can be natural ingredients in getting rid of ants. Always go for other toxic methods if you have large scale infestation where these natural methods fail.

How to Get Rid of Ants With Cayenne

It’s not uncommon to find ants crawling around inside your home. Any little crumb on the floor or countertops can lead to a trail of ants. Pesticide sprays are available to kill and deter ants; however, these products often contain toxic ingredients. Opt for a natural product — cayenne pepper — to get rid of ants.

Step 1

Locate the areas where the ants are entering. This is easy to do by following the ants to where they are exiting. Usually, the ants are gathering food to take back to their colony.

Step 2

Sprinkle cayenne pepper in a line all along the places where you see ants and where they are entering or exiting. The pepper creates a barrier that the ants won’t cross. They will turn around and go right back out.

Step 3

8 Effective Carpenter Ant Killers on the Market

Here is a list of the top eight carpenter ant treatment options that I recommend considering to get rid of these pests. The pros and cons of each item should help you select the best carpenter ant killer for your needs.

Bayer Maxforce Carpenter Gel 4314807 – Best Carpenter Ant Bait Gel

Bayer is the manufacturer of a highly helpful Maxforce carpenter ant bait gel. It is among the largest pharmaceutical companies in the world. Bayer produces some chemical products, such as agricultural chemicals, consumer healthcare products, and biotechnology products.

This advance carpenter ant bait is a sugar-based gel with a sweet smell to attract ants. It is also high in moisture to allow the ants to consume it easily. The gel can kill all the common species of ants, including carpenter ants, bullet ant, banded sugar ants, argentine ants, among others.

Maxforce gel contains fipronil. When an ant consumes this gel, the ingredient kills it slowly. This way, the ant carries the bait to its colony, which eventually results in killing the queen. This makes it an effective carpenter ant bait in getting rid of an entire colony because ants can’t survive after the queen has died.

This Maxforce solution removes ants completely from three to five days after insects eat the baits. This is the reason why I find this item the best carpenter ant killer for homes infested with ants. Put this gel on the places where you have spotted ants the most for even quicker results. You can apply it in crevices, pipes, or cabinets.

The Maxforce gel should not be placed in areas that have been sprayed by insecticides. This is because the ants have a strong sense of smell, and they may smell the poison and avoid the gel. I advise using this gel alongside other protein-based baits to get the best results.



  • has a sweet smell to specifically attract carpenter ants;
  • the bait kills the whole colony;
  • can easily be applied in small spaces and crevices.
  • must be placed on the ant paths.

Basf Advance Granular Ant Bait – Best Product to Kill Carpenter Ants

Basf Advanced Granular Carpenter Ant Bait is the second product among our recommendations. This German company was founded in 1865, and it is the largest producer of chemical products in the world. It has subsidiaries in over eighty countries worldwide.

This Basf carpenter ant bait is made with an active ingredient called abamectin B1. This is a slow-killing ingredient that allows the carpenter ants to carry the poison back to their colony. What kills carpenter ants best than this product, which can destroy the entire colony together with the queen? Indeed, there is no better way to keep your home protected from pests.

This solution is a combination of protein-based attractors and large granular-sized baits. The baits can be placed anywhere around, and in the house, so you can spread the treatment not only in the kitchen and rooms but around the foundations in cracks and crevices. You should also put baits in areas where you have noticed the signs of ants to get desired results.



  • a highly-efficient granular bait;
  • can kill the whole colony;
  • can be used both indoors and outdoors.

Talstar Pros Pest Control Insecticide – Professional Carpenter Ant Killer

Talstar Professional insecticide is a product of the FMC Agricultural Products company. This firm is renowned for producing some of the most effective insecticides for more than a century.

Talstar Professional comes in a 3/4-gallon bottle. In addition to effectively killing carpenter ants, this solution can be used to get rid of many other insects in your home, including mosquitoes, termites, centipedes, bees, bedbugs, spiders, etc.

For this insecticide, FMC uses 7.9% bifenthrin as the main active ingredient. This makes Talstar Professional a fast and effective carpenter ant killer because bifenthrin is synthetic parathyroid, which affects the insect’s nervous system and, therefore, weakens it before finally killing.

The high bifenthrin content means you can dilute the Talstar Professional solution with water, and it still remains effective in killing ants. The amount of water to add depends on the size of the infestation. For example, if you want to treat a mild infestation, 0.33 ounces of Talstar solution for every gallon of water should be enough. For indoor spaces, I recommend 0.5 ounces of this insecticide per gallon of water. And for the bad infestations, I advise using at least an ounce of the product for every gallon of water.

For Talstar Professional to work best, you should leave it to dry. I always leave the pesticide for at least thirty minutes to allow it to dry completely before letting people step on the treated area. When applying outside, I also make sure the area doesn’t come into contact with water. So, it’s best to use this solution during dry seasons, as rainfall can make it ineffective.

I recommend using a pump sprayer when to allow an even distribution of this carpenter ant spray. Also, you can use other ant treatment methods like baits alongside this product.

You can use Talstar Professional both indoors (only in cracks) and outdoors for treating your home, office, commercial areas, etc.
