Crazy Ants Invasion | Eradicate & Prevent Unwanted Guests

If you’ve noticed a large group of ants frantically moving around your home, you may have a problem with crazy ants. Unlike other ants that move in a straight line, crazy ants are known for their erratic patterns. Because they reproduce quickly, it’s important to act quickly and eliminate them immediately.

To get rid of crazy ants, start by eliminating their food sources and using ant baits or insecticide sprays designed for ant control. Place the baits near areas where the ants have been seen and use insecticide sprays to target any visible ants directly. Be sure to follow the instructions on the product label carefully and keep children and pets away from the treated area. It’s also important to seal entry points for long-term prevention.

Once you’ve eliminated them inside your home, set up outdoor ant killer baits and wait up to a week for the colonies to be eradicated. By taking these steps, you can effectively eliminate them and prevent future infestations.

In addition to being a nuisance, crazy ants can also have a significant impact on the ecosystem. By learning more about these ants and their behavior, you can better understand their role in the environment and how to become a crazy ant expert.

Get Rid of Crazy Ants With Natural Home Remedies

If you prefer using natural home remedies for pest control, there are a few solutions that you can try to get rid of crazy ants.

• Diatomaceous Earth

One option is diatomaceous earth, a common and effective powder that can be placed anywhere you find a large group of ants. You can also mix it with sugar to attract more of them. However, the diatomaceous earth must stay dry at all times, as if it gets in contact with water, it will lose effectiveness.

• Vinegar Solution

Another option is a mix of vinegar and water. Spray it in places the ants have used to enter your home, as it interferes with their scent. The solution needs reapplied regularly, but it is still my preferred method.

• Borax

You can also make a DIY ant bait by adding warm water, 1.5 tablespoons of borax, and half a cup of sugar. Soak cotton balls in the solution and place them on crazy ant trails where you’ve detected their activity. When the ants take the bait, they’ll carry it back to the colony and spread it around. Although this option may not be as effective for crazy ants as other ant species, it’s worth a try.

How to Get Rid of Crazy Ants – Step-by-Step

Inside the House

To get rid of crazy ants inside your home, the first step is to locate their entry points. This can be challenging due to their erratic patterns, so placing ant killer bait is necessary. Once they’ve found the bait, they’ll form a steady line of worker ants that can lead you to their nest.

Once you’ve found their entry points, use a dust or granule insecticide with a residual effect to cover those spots. Using a spray insecticide for the visible ants and foraging inside your home can also be effective. Once you find where the ants are coming from, you have halfway through to eliminate the problem.


For outdoor infestations, finding the crazy ant nests can be difficult due to their tendency to forage far away from their homes. Liquid insecticide designed for destroying ant nests is recommended, but ant baits in granules can also be effective and more environmentally friendly. Simply spread the ant bait granules near the suspected nest and wait for the ants to bring it inside, which should produce results relatively quickly.

By following these steps, you should be able to get rid of crazy ants both inside and outside your home.

Crazy Ants in Specific Places in the House

Crazy ants are attracted to warm places, and as the temperature drops in the autumn, they may seek shelter inside your home. Here are some specific places in your home where you may find crazy ants and how to get rid of them:

• Bathroom

High humidity levels in the bathroom make it an attractive place for crazy ants. They may hide behind the washing machine or beneath the tub if there are cracks in the tiles. Use dust or spray insecticide to destroy their population locally.

• Kitchen

Crazy ants are attracted to electrical appliances, which may commonly inhabit your kitchen. They tend to hide behind kitchen counters and in electrical sockets. Use spray insecticide to eliminate any crazy ants in your kitchen instantly. Protect your supplies from the insecticide and thoroughly clean the kitchen after eliminating the ants.

Crazy Ants in Car: What Should You Do?

Crazy Ants in Car

Crazy ants may invade a car in search of a food source, and once they find it, they leave a trail of pheromones behind them for other ants to follow. Here are some steps to get rid of crazy ants in your car:

Start by checking your car for any food leftovers and thoroughly clean up the entire car. Even if the food is in your car, crazy ants can easily sense it, so keeping your car as clean as possible is essential.

Next, change the spot where you park your car for a while. This will break the pheromone trail and deter the ants from coming back.

Sometimes, you may unknowingly park your car near an anthill or a crazy ant mound. Check the surroundings of your car to see if there is a large number of ants nearby. If you find their colony, you can either change your parking spot or use methods to destroy the nearby crazy ant colony.

What Are Crazy Ants?

Crazy ants, also known as Nylanderia fulva, are an invasive species of ants that originated from South America and have spread throughout the Gulf Coast region of the United States since their first detection in Texas in 2002. These ants are known for their erratic movements, which earned them their common name, and have become a significant pest in the affected areas.

Types of Crazy Ants

It’s worth noting that there are several types of crazy ants, each with its unique characteristics and behaviors. The most frequently encountered types of crazy ants include the following:

  • Rasberry crazy ant, also known as the tawny crazy ant, is named after the exterminator who first discovered them. They are known for their reddish-brown color and erratic movements.
  • Longhorn crazy ant, also called the black crazy ant, is named for its long antennae and dark coloration. They are a significant pest in agriculture, and their stings can be painful to humans.
  • Yellow crazy ant is a pale-yellow colored ant that can form massive colonies and can significantly impact the ecosystem. They are known to displace native ant species and harm other animals.
  • Caribbean crazy ant is found in Florida and the Caribbean, and they have a reputation for invading homes and buildings. They are known for their erratic movements and can quickly form large colonies.
  • Brazilian crazy ant, as the name suggests, is native to Brazil and is now found in the United States. They are known for their preference for moist environments and their ability to displace native ant species.

Rasberry Crazy Ant Queen

One distinctive feature of these ants is their colony organization, which typically includes multiple queens in one colony, unlike other ants with only one queen per colony. A single colony of crazy ants can have as many as 40 queens, contributing to their fast reproduction rate.

What Does a Crazy Ant Look Like?

Crazy ants are relatively small, with an average size of around 3 millimeters for workers. They have distinctively long mandibles, which make them easily identifiable. Most crazy ants are entirely black, but some species are dark brown and have long legs compared to the rest of their body.

Do Crazy Ants Bite?

Unlike fire ants, which are native to the same region, crazy ants do not sting. Instead, they only bite, and their bite is not poisonous. While their bites may cause temporary pain, they generally do not provoke allergic reactions. The primary danger of crazy ants is their ability to reproduce quickly and form large colonies, which can quickly take over yards and homes.

It’s worth noting that crazy ants have developed an antidote to the venom of red fire ants, which is an interesting case of one insect being able to neutralize the venom of another.

What Do Black Crazy Ants Eat?

Black crazy ants have a diet similar to most other ant species, and they feed on small insects, leftover food, seeds, plants, and sweet fruits. Keeping everything clean and free from food scraps is crucial to prevent them from invading your home.

Are Crazy Ants Dangerous?

One of the biggest challenges with crazy ants is their ability to reproduce rapidly and their peculiar movement patterns, which make them difficult to eliminate compared to other ant species. However, they are not dangerous regarding their bites or venom, so you needn’t worry about allergic reactions or painful bites.

Crazy ants are characterized by their erratic movements, distinguishing them from other ants. This frenzied behavior makes them a challenging pest to combat. Additionally, their small size can make it difficult to identify their source.

They build their colonies in moist and dry environments, with warmth crucial in their habitat selection. They do not nest in soil but create their homes under rocks, logs, and compost piles. In the winter, they may invade homes to stay warm.

These ants are notorious for infesting electrical equipment such as outlets and air conditioning units and cracks in walls, floors, and furniture. Regardless of where they have taken up residence in your home, we will provide tips for eradicating them.

Interestingly, even the NASA Johnson Space Center community has faced issues with crazy ants.
