5 Steps Guide on How to Get Rid of Red Ants

Red ants are a common pest in the United States and can be difficult to get rid of. Here are 5 steps on how you can get rid of red harvester ants for good!

Step 1: Identify the Ants

Step 1: Step 1: Identify the AntsThe first step is to identify the type of ant that you are dealing with. Red harvester ants can be quite devastating, so it's important not to try and treat it yourself, especially because you need special treatment for them due to their size alone.

You might think identifying red ants is easy - just look at them to make sure they're red! But not all red ants are red harvester ants. And these ants can range from red to dark brown in coloration.

"Red" ants are common in Texas and throughout the Southwest, especially at high elevations. They are relatively large for ants, growing to between a quarter and a half-inch long.

In body shape, red ants are rather elongated, with squarish heads. Unlike some ant species, they do not have spiny bodies.

Swarming Habits of Red Ants
After a summer rain, you may see thousands of red ants from multiple colonies swarm all over your property. Male swarmers are larger than worker ants and are winged. If you see ants climbing to high points to wait for a mate, called "hill-topping, " that's a tell-tale habit saying it's harvester ants. Swarming takes place on a single day, but if you are ready with pesticides, it's a great chance to curb red ants' population growth.

Red ants hillYou can also identify red ants by their very sizable ant hills, which are so large we must call them "mounds" (up to 50 inches in diameter!). And the area around the mound will normally be stripped of all vegetation.

Spiraling out from the mound entrance, you should see long ant trails, and if you care to sniff down close and have a perceptive nose, you can even identify these ants by the distinctive smell of their trails!

What Do Harvester Ants Eat?

If you are suffering from a harvester ant infestation, you may well think you know what harvester ants eat - YOU! These ants are extremely aggressive, and their bites are stinging painfully, and even poisonous.

However, the true food of red harvester ants is all manner of seeds and greens, including:

  • Sunflower seeds,
  • Wildflower seeds,
  • Grass seeds,
  • Clover heads,
  • Alfalfa.

But in a "pinch, " so to speak, red ants will also eat other insects. After all, a little protein in the diet is a good thing.

Harvester ant workers are industrious foragers. They often infest farm fields and rangelands and significantly decrease the yields achieved by "harvester people."

"Harvester" ants get their name from their penchant for seed-gathering.

Finally, note that recent breakthrough scientific studies of harvester ants have discovered that these ants typically do not chew through the hard seed shells. No, they wait for the seeds to germinate and then eat the tender sprouts. Yes, they are farmers!

Step 2. Do a Major Clean-Up

Step 2: Step 2. Do a Major Clean-UpGet rid of extra food particles on the floor, any easy sources of water you can block off, and excessive clutter. Red ants are especially attracted to sugary or greasy foods, so do your best to clean up any messes and keep things tidy!

There are natural predators of red ants, such as the Texas horned lizard, that may be able to keep ant populations at equilibrium. But unless you take drastic action, red ants will continue to thrive on your property unhindered indefinitely.

But there are a few things you can do to make your property less inviting to these ants.

These tips my help prevent an infestation or help control an existing one:

  • Pick up any random debris, garbage, or clutter in your yard. Eliminate anything that can give ants shelter.
  • Fix any leaking outdoor faucets, hoses, or sprinklers. Dry up any places where puddling repeatedly occurs after rain.
  • Don't leave pet food or human food around for ants to find. Re-position and better secure garbage cans if necessary.
  • Cut down tall grass near outdoor structures. Move mulch and plants back from foundations, where ants often like to congregate.

Step 3. Using Ant Control Products

Step 3: Step 3. Using Ant Control ProductsUse a multi-faceted approach. Place gel baits at key points where ants congregate. Lay down non-toxic granule baits along walls where ants trail. And have a spray can quick at hand for “spot treatment.”

There are a plethora of anti-ant products on today’s market, and it is possible to concoct your own ant killers as well.

When using ant control products, always be sure to read the directions carefully and follow them to the letter. Improper use of such products can be harmful not just to the ants, but also to you and your family.

Red ants can get in through cracks in foundations, gaps around windows and doors, and even though tiny spaces on the roof.

If you can find and seal off these entry points, you will greatly reduce the chances of the ants invading your home again. And it will also make it easier to treat them when they are already inside.

Step 5. Find the Outdoor Ant Hills and Kill Off the Colony

Step 5: Step 5. Find the Outdoor Ant Hills and Kill Off the ColonyOnce you have sealed off the entry points, it is time to do some serious hunting. Control is one thing, but what you want to do is kill those pesky red ants once and for all. Below, we look at how to kill red ants outside.

Destroying their colonies, baiting their trails, dusting the plants they love to climb on, and dehydrating them with diatomaceous earth (you can also use grits!) are the chief methods.

Red harvester ants typically set up their nests in soil that has easy access to water. They will travel quite far from their nests in search of food, but they prefer established trails. If you can find these trails - which are often along with home foundations or sidewalks - then it is possible to locate the colony!

Once you have located the source of the problem, use a pesticide specifically designed for outdoor ant control to kill off all of them. A treatment here should be enough to rid your yard of red ants for good!

How to Kill Red Harvester Ants Outside

Getting more specific, here are the major ways to wipe red harvester ants out of doors:

  • Douse their ant mounds and immediately surrounding areas with deadly toxic ants. This is the number one most effective method.
  • Litter deadly ant baits near the nest and all along the main ant highways. The ants will bring home your "gifts" and eat their last meal. Use can use granular baits or mix honey/peanut butter with things like boric acid.
  • Mix flour with baking soda and then dust the base of plants ants are likely to be interested in. This will keep them away and help to starve them because baking soda is poisonous to ants.
  • Dehydrate ants by dusting their trails with diatomaceous earth. The ants will pick it up, take it home, eat it and die of dehydration.
  • Looking for a fun way to kill an ant colony? Boil them to death! Be careful with this method, but after rain when ant tunnels are muddy, it can be very effective. Pour 2 or 3 gallons of boiling water into each anthill.

Red ants mostly like to keep themselves outdoors, but winged swarmers will wander inside at swarming times. And if ant hills are built nearby your home's foundation or in a garden not far from the house, they certainly may intrude and forage for food in your abode.

Typically, however, they won't stay indoors regularly and will do more damage to your lawn than to your home.

Find the outdoor hills where indoor ants are coming from. Use methods described above to boil, poison, dehydrate, or otherwise kill off the colony. Also, you can look and pick up the best outdoor ant killer from my review here.
