Terro Outdoor Liquid Ant is the most effective way to eliminate ants in a short time, and it is designed to eliminate the entire colony.

Terro Outdoor Liquid baits also come repacked and filled, and you can use them immediately, making the process less time-consuming and easy. However, the ant baits cannot stay in one place for a long time as they thicken and solidify, reducing effectiveness.
2. Amdro Ant Block Home Perimeter Ant Bait Granules
Amdro Ant Block granules are the best ant killer for lawns for maximum effectiveness, and they work to kill the entire colony by releasing a slow-acting toxin or poison.

You will apply it by shaking the granules out in a wide band around the perimeter of your home, and it will take about 7 to 14 days to kill the whole colony.

Also, because the bait is natural with no chemical compounds, insects will not form resistance as it is a mechanical action that will kill the ants within 24 to 48 hours, leaving your lawn ant-free.

What Are The Types of Outdoor Ant Killing Products?
There are several types of outdoor ant killers. Most of them contain a slow-acting insecticide known as Borax. Its nature will take advantage of the ant's social nature, infecting the queen, larvae, and the entire colony. Some of the types include:
a). Liquid Baits (Liquids and Gels)
This liquid ant bait is a sweet solution used as the attractant or bait stations, whereas the gel baits are dispensed with a syringe which can be great for the hard-to-reach areas the normal granules and traps would not reach.
There is a range of liquid sprays and aerosols available as contact killers and barriers that will surround your house. So when you spray this outdoor ant killer on the ant trail or around the house, it will act as a deterrent.
c). Solid Baits (Granules and Dust)
Granules are a protein bait type that is applied by spreading on your lawn and for the dust them include such as Diatomaceous Earth which dries out the exoskeletons or nervous system of ants and other insects. The granules might be better than Diatomaceous Earth because the rain might wash away most of the dust.
Factors to Consider Before Purchasing the Best Ant Killer for Lawns
1. Type of Ants
There are different species of ants, and they also get attracted to different things, and some include:
a). Odorous Ant
Odorous ants are called so because they stink and are hard to squash as they are resilient, meaning they can stand up to soft and cheap ant treatments. Unfortunately, these types of ants are hard to get rid of because they can withstand a lack of food and adverse weather, so you have to use a strong product to eliminate them to avoid establishing an inside colony.
b). Carpenter Ants
Carpenter ants are probably one of the largest ants in yards, and they range from orangey-red to black and have pronounced pincer jaws and large heads. A carpenter ant has strong jaws which dive into the wood and may cause plenty of damage to your home in a short time, so once you see them on your lawn, you should act fast.
c). Fire Ants
These fire ant species are prevalent pesky critters and safety risk because they sting and bite when threatened. The string makes a human feel like their skin is on fire and can last for a few hours with continuous itching around the area for up to a week. A single fire ant colony can have up to a million ants, and the fire ant mounds are the first sign to notice, but there's probably a whole colony underground by the time you notice.
d). Ghost ants
This type of ant is a tropical species and will often be seen in warm climates, and when the weather is cold outside, they will find a way into your home. The ghost ants are difficult to spot but are super active as they branch off from already established colonies and start new ones, and by the time you spot them, chances are they have already spread all over your yard or lawn.
2. Size of Lawn and Infestation
Whenever you are looking for a spray treatment or lawn-specific product, you will need to keep in mind your lawn size, and this way, you will make a purchase that will fit your whole lawn area. Once you know your lawn's size, check each product for the estimated area coverage. Also, remember to read the details carefully as it may require you to apply the ant bait in a concentrated form for a large ant infestation or less if the ants are far between.
Since the lawn is outside, purchasing a waterproof ant killer is necessary to avoid the outdoor ant treatment being washed away during the bad weather. The best ant killer for lawns should have a formula that will not be washed away or blown away, which will mean you will use less money and minimum applications.
Additionally, the waterproof outdoor ant killer will be more effective and fast-acting to deal with the problem and reduce the risk of fire ants vacating your home. However, some of the best ant killers will use harsh chemicals that will make them weatherproof and effective, but they may also be harmful to your grass.
4. Pet and Child-Friendly
This is an important consideration for most yard owners because if you have kids and pets, the last thing you want is to use an ant killer product that will be a health hazard for your children and pets. In addition, harsh formulas mean the product will only get applied when your pets and kids are away from your yard, which is not realistic. Therefore most parents usually opt for home remedies or organic, all-natural products.
5. Bonus Features
Some of the best ant killers not only deal with ant infestations but also work great with spiders, cockroaches, ants, and other insects. Therefore, if you have numerous pests on your lawn, you can either opt to go with a separate best ant killer for lawns or choose a versatile option that will clear all your infestations at a go.
Frequently Asked Questions on the Best Ant Killers for a Lawn
1. How do I permanently eliminate ants outside?
To permanently kill ants, you will need to kill the entire colony. Many ant killers usually attract insects which will then feed on the bait and then bring it to the queen, and when the queen dies, you are guaranteed the whole colony will die. However, a new ant colony can develop again, so permanent protection is not guaranteed even when you have killed the original colonies.
2. How do I eliminate fire ants in my lawn without killing the grass?
You can do this by creating a 2% insecticide spray by mixing one tablespoon of soap with quarter water, combining the mixture, and then putting the liquid into a spray bottle. Next, spray some soapy water on the plants, visible ant trails around the entire colony, and the mixture will break down the ants' resistance to water and eliminate them without killing your grass.
3. What is the ant bait that will work overnight?
Among the most effective ways to kill the colony is using Borax which is a product that is 100% natural and is found in most ant and pest-control products. It is easily available in your nearest convenience store or supermarket. You will need it to soak the Borax mixture with cotton balls and then place your cotton balls near any ant trails to kill the ants around your home.
4. Can I get rid of ants without killing them?
One of the cheapest ways to get rid of ants naturally without killing them is using table salt. Spreading some salt near the corners, nooks, cracks, and crevices where ants enter will ensure that the ants stay away. A salt line will act as a barrier, and a salt-boiling water solution spray will help in repelling and will not kill the ants.
