Who This Is For


Just one tiny ant can make the most glamorous kitchen feel like a dumpster. And fire ants can make your yard a venomous minefield that poses a serious health risk. Whichever ant problem you have, this guide is for anyone who wants to take a few simple steps before calling a professional.

If you spot a few ants indoors, dont buy anything just yet. Clean your kitchen as thoroughly as you can, looking for unknown spills. Ants are coming in for some reason, Rollinss Glen Ramsey said, and more often than not, that reason is food. Typically, if you get rid of whatever theyre feeding on, the ants will go away. Wash your trash can out. Empty the cabinet under the sink. If that doesnt work, try a bait.

A word of caution from Ramsey: With DIY treatments, you could make it worse, you could make it better. If you put out ant bait and youre still seeing ants after a week or two, something is going wrong in your treatmenttheres an unknown food source, a hidden nestand its time to call a pro. Ramsey added, If it keeps getting worse and worse, it gets more challenging for us, too.

How To Get Rid Of Black Ants

1. The first step to take is to figure out where they come from and where their nests are located. As the University of California experts recommend, regularly inspecting your home for ants or their entry points. Monitor for ants near attractive food sources or moist areas.

2. Your main aim is to kill the queen.

The University of Kentucky specialists warn that the mistake most people make when attempting to control ants is only spraying the ants they see. This approach usually fails because the ants seen foraging over exposed surfaces are only a small portion of the colony.

Typically, there will be thousands of additional ants including one or more egg-laying queens hidden somewhere in a nest. Eliminating queens and other colony members within nests is often the key to effective ant control. Our review of TOP 12 black ant killers will help you decide on which product you should purchase.

3. The only way to achieve your goal and kill the queen is to feed it poison.

There are a great number of various slow-acting baits, and such poison acts like domino. A poisoned insect has enough time to share a poisoned piece of food with others and their queen before dying. Not only does this worker carry some food into the colony, it also attracts others to the bait. If used properly, baits and poisoned bait stations are much safer than sprays.

Baits are the key method of getting rid of black ants.

Terro Best Outdoor Liquid Ant Bait

One of the best outdoor ant killers is Terro Outdoor Liquid Ant Baits. These baits are usually the go-to choice for many individuals. Terro is sold in a 1-oz pack of six and every station is pre-filled and ready to use. Terro baits work by attracting and killing ants lingering in your outdoor home area. The product has been proven to kill different species of household ants outside your home before they even get into the house. Terro can also be used for large ants infestations.

How Do Terro Liquid Baits Work?

Similar to other liquid baits in the market, Terro works by killing ants in a slow manner. This is achieved through the interference of the ants digestive system, which then kills them. The product is quite effective because this slow killing mechanism provides a chance for worker ants to transport the bait to the colony and the queen.

Using Terro liquid baits is quite easy and you should not have a problem applying them on your outdoors. All you have to do is place the stakes on the ground and the ants will be attracted and carry them to their nests. The only major thing to do here is to place the stakes where you see a lot of ant activity.

What to Know Before Using

  • Easy to use, as all you have to do is place the stakes on the areas with the most ant activity.
  • Eliminates an entire ant colony.

A Special Case: Fire Ants

One species, the imported red fire ant, causes the most pest problems of all. Not only do fire ants disrupt turf with mounds, they pack a sting that raises a white pustule and burns badly enough to give the species its name. And yes, fire ants really do sting all at once, or close to it. They like to climb vertical surfaces like, oh, say, your legs. When one senses danger, it emits a pheromone that signals its mates to bite.

The North Carolina State University Extension explains that fire ant nests can often go undetected until a heavy rainfall causes them to build up a mound to escape groundwater. As the colony grows, the ants will continue to build, especially beside concrete or in sunny areas for the extra warmth.

To control them, research has shown drenching mounds with a large volume of very hot water can significantly reduce their activity. Unfortunately, satellite mounds near the original can form in just a few days.

Texas Agrilife Extension Service recommends a two-step approach: A pesticide bait, followed by individual mound treatment.

Commercial pesticide baits are often made of corn grits and soybean oil, with a low-dose ant poison mixed in. It is low in toxicity for humans but ants carry it back to their mound. Its about 80% effective but takes weeks or months to do its job. Step 2 is hitting the mounds with either a chemical pesticide or boiling water.

How To Use Ant Bait

Fire Ant Killer That Works Great – Kill Fire Ants Fast

The way that you apply ant bait helps to determine how effective it is. Heres the best way to use ant bait to make sure you get results.

1. Spend some time watching the ants locate their trails. These are the routes they travel when looking for food which means its the perfect place for bait. If you find more than one trail, bait everyone.

2. Check the trails every day and reapply the bait when its gone. If the bait is still there, its possible youre using the wrong kind of bait and the ants dont want to eat it. If this is the case, consider switching to another kind of bait.

3. Keep placing the bait along each trail until you stop seeing ants there.

4. Once the ants have started taking the bait, wait. It can take weeks for a colony to be wiped out.

Here are some helpful hints to make sure you have the best possible chance of the bait being successful.

  • Use bait stations if needed to protect the bait from inclement weather.
  • For best results, bait should be applied in temperatures about 70 and less than 90 degrees F. If the temperature is too hot, consider laying bait in the evening as thats when the ant will be scavaging for food.
  • Dont place bait early in the morning if there is any dew on the grass.
  • Dont use any type of repellant near the bait.
  • Remove any other sources of food if you can, including things like trash cans and pet food.
  • Discard any unused bait after 6 months or so because it will no longer be fresh and the ants will not be attracted to it.

Isnt Raking Over Ant Hills Sufficient

Ants prefer dry, well-drained soil in an undisturbed low traffic area, making your lawn the perfect place for them.

For a minor infestation, giving your lawn a good raking each week will help to remove dead grass, aerate the soil, plus it will disperse the ant mound as they build it. Making them start over each time.

However, if you have a severe infestation with multiple mounds, raking is unlikely to have any effect. Established colonies will spread across a large area underground and have upwards of 5,000 ants living in it.

So, if a mound is raked out or mowed over, they can rebuild it seemingly overnight. In these instances, you will need to treat the ants directly with lawn specific ant treatment.

We have an accompanying guide on how to get rid of ants in your lawn that we recommend you check out alongside this product guide.

What Is An Insect Growth Regulator

An insect growth regulator is a chemical inhibits the life cycle of an insect by mimicking or inhibiting one of the hormones involved in the molting process which is necessary for growing insects to form a new exoskeleton that is larger than the previous one. This causes premature molting or interrupting the transformation from larva to adult.

Insect growth regulators in Canada

While the number of IGRs legal for use in Canada is limited compared to the US, justification is typically provided and is often due to their health risks to humans. Unfortunately the distribution of those that are legal seems to be limited to commercial companies and/or only in larger quantities.

Soil Drench Powder Granules Baits

N.C. State offers some advice for how to get rid of ants yourself via soil drench, powder or granules, and baits, and the characteristics of each product type.

Soil drench:

  • Fast-acting, best applied in high-traffic areas with low tolerance for ant activity
  • Must apply with at least two gallons per mount to reach the queen in the nest
  • Best applied mid-morning when ants are closest to the surface
  • Do not physically disturb the mound before or after application


  • Apply to the top of the mound and follow up with irrigation
  • Make sure irrigation is significant enough for the active ingredient to reach the queen


  • Slow acting, may take three days or up to two weeks
  • Do not place bait stations on top of the mound, but within a two-foot radius around the mound
  • The product must be fresh and kept dry

Bachman doesnt recommend the home remedy of using instant grits as ant bait and killer. Folks think the ants eat the grits and the grits then expand inside the ant and kill it.

But worker ants dont eat solid food, he explains. They give the food to other ants still developing inside the nest, who vomit up liquid food that other ants then eat.

So using instant grits is essentially feeding the ants.

The insecticides that Bachman recommends using are carbohydrates with the poison attached. That means when those other ants vomit up the food, it contains that insecticide that then kills the ants.
