The sting of a red fire ant can send you into a frenzy. Their sting feels like burning and can cause reactions that can send you to the Emergency Room. The red fire ants have a reputation for attacking human beings and animals that approach their nest.

The pain from the fire ant sting is categorized as level one. This is below that of the bee sting, but as anyone would tell you, the sting is no fun at all. If you find them in your garden, it’s time you took measures to get rid of them. The following are some of the best fire ant killers on the market.

What you need to know when killing fire ants

What are they?

There are more than 200 species of fire ants. The most common among them include the black fire ants, the red ants, and the native fire ants.

Larger colonies can have more than 250,000 foragers that travel long distances searching for food. They are commonly reddish and feed on both meat and vegetables. The ants tend to love anywhere there is an electrical current, and you can find them on an electrical socket.

The red fire ants can destroy an electrical installation and so it is possible to find yourself wandering in darkness while your neighbor has power.

What to look for before killing the fire ants

The mound is the best indication of fire ants. And unlike other common ants, fire ants tend to tunnel underground. There is no central entrance at the center of the mound.

After a massive rainfall, the mound tends to look fluffy.

Before going for a particular product, determine whether the fire ants are indoors or outdoors. Then consider how fast you want to get rid of them.

In the majority of cases, fire ants are not fond of venturing into your house for food. However, the red imported fire ants can invade your home and make it inhabitable.

When do fire ants come into your home?

They tend to venture indoors in times of hot and dry weather. They can also go indoors when heavy rain destroys their mound. Before you take action, first look for their entry point and seal it. This is a temporary solution before you can determine the best course of action.

If you have no idea about the location of the mound and they are not a source of an immediate problem, you can think about baiting them.

Though we strongly recommend using an ant killer, there are different home remedies that you can consider trying. Some of these suggestions have been used with success by people while others have failed.

Essentially, baiting is usually the most effective method of ridding yourself of the ant menace. However, if they are a source of a significant problem, sprays are much more efficient. Spraying kills the fire ants instantly through contact.

Unfortunately, this is a temporary solution and may only deter them for just a short period. The ants can return if they feel that the coast is now clear. This means that you will have to use the spray again and again and may thus prove an expensive option. In the end, you may be forced to employ a different tactic.

As a rule of thumb, stick to baiting and traps as they are more efficient than quick solutions.

Home Remedies for Fire Ants

Though we strongly recommend using an ant killer, there are different home remedies that you can consider trying. Some of these suggestions have been used with success by people while others have failed.

The remedies include:

  • Using a mix of dish soap and water
  • Using a little gasoline and lighting the mold
  • Using a mix of white vinegar and water
  • Using water to flush out the ants
  • Using grits
  • Using club soda
  • Lemon juice may help

If the fire ants are outdoors

The most effective remedy for killing red fire ants is mound treatment. Of course, you will need to first determine where the mound is located. Mound treatment takes just a few days before you start seeing the results. The most common types of mound treatment include the following.

  • Mound injection: this method involves injecting the ant killer into the mound. This may prove a potent poison but may fail to reach the queen.
  • Mound drenching: this is where poisonous liquid or boiling water is poured on the mound. The method kills fire ants through contact. This method is not sufficiently effective and may fail to kill the queen and some of the ants that are underground.
  • Powdered insecticide: the powder is typically applied around their location or on top of the mound. The method can kill many ants and reach the queen – the ultimate goal is reaching the queen.
  • Baiting: this technique may be the slowest but is also the most effective. Baiting is an innovative way of making the red ants eat the substance and kill them slowly as they share the poison with other colony members. Baiting usually kills the queen within a few days.

Home remedies include boiling water and pouring it over the mound. You can also use the old-fashioned method of burning the mound. However, these home remedies are not the most effective.
