What Are Crazy Ants?

Types of Crazy Ants | Different Names

Also, it is good to know that there are several types of crazy ants, and the most common ones are:

Rasberry Crazy Ant Queen

Another distinctive crazy ant feature is their colony organization. In most cases, other types of ants have one queen per colony, but crazy ants almost always have multiple queens in one colony. The number of crazy ant queens can go up to 40 queens per colony, and this is one of the reasons for their fast reproduction rate.

What Does a Crazy Ant Look Like?

There are several types of crazy ants, but their size on average for workers is around 3 millimeters. They have very long distinctive mandibles when compared to the rest of their body, so they are easily recognizable. Most crazy ants are completely black but some species are dark brown, they are rather small when compared to other ants, and their legs are long when compared to the rest of their body.

Do Crazy Ants Bite?

They originated from the same territory as fire ants, but unlike them, crazy ants don’t sting rather they only bite. Crazy ant’s bite is not poisonous and the pain goes away after a minute or two. Their bite in most people doesn’t provoke any allergic reactions and the only dangers that can come from crazy ants are their numbers because they can take over your yard or home very quickly.

Since crazy ants originally came from the same living space as red fire ants, it is interesting to know that they developed an antidote for the red fire ant’s venom. This is the first recorded case in nature that one insect can neutralize the venom of the other insect.

What Do Black Crazy Ants Eat?

Crazy ants have the same diet as most of the other ants. They eat small insects, leftover food, seeds, plants, and sweet fruits, so it is imperative to keep your home clean from any food scraps in you want to prevent them from invading your home.

Are Crazy Ants Dangerous?

The main problem that comes with crazy ants is their large numbers. Crazy ants are reproducing quickly and their unusual moving patterns make them harder to get rid of than when compared to other types of ants. They are not dangerous when it comes to their bites or venom, so don’t worry about any allergic reactions or painful bite marks.

There are several species of crazy ants and all of them are all known for their erratic movement which distinguishes them from the rest of the ant species. That frantic movement makes crazy ants a hard pest to fight. They are also very small for an ant, so that can also be another problem when trying to find where they are coming from.

Crazy ants choose to build their nests in moist and dry places, and one of the most important things they care about when choosing a habitat is for it to be warm. They don’t nest in the soil, but instead, they build their colonies beneath rocks, logs, or compost piles. In the winter they infest homes in order to keep themselves warm.

They are also well known for infesting electrical equipment such as electrical outlets and air condition units. Besides that, they can infest cracks in the walls, floors, and furniture. No matter what they infest in your house, we are going to show you how to get rid of them.

Fun fact is that even NASA Johnson Space Center community had problems with crazy ants.

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

How to Get Rid of Crazy Ants Inside the House | Indoors

The hardest part about getting rid of crazy ants from your home is to locate where they are coming from. Their frantic and unpredictable moving patterns make it hard to locate their entry points, so placing some type of ant killer bait is necessary. After they notice the bait they will form a steady line of worker ants and carry the bait (food) back to their nest. That will give you a chance to follow them and see where they are coming from.

After you find their entry spots, use some type of dust or granule insecticide with a residual effect, and cover those spots. The use of dust or granule insecticide has shown the best results because it covers more ground which is essential because of their unusual moving patterns. For all the other ants that you can see foraging through your home, you should use an insecticide in the form of a spray.

This treatment takes care of any indoor ant problems and if you want to take care of this problem for good, you will need to find where are the ants coming from.

How to Get Rid of Crazy Ants Outside | Outdoors

After you followed their trail and found their mounds and nests, it is recommended to use liquid insecticide specially made for destroying ant nests. This sounds easy but in reality, it is going to be extremely hard to find their nests as they are famous for foraging far away from their nests. Now, add the facts that they are really tiny, it is going to be almost impossible to follow them to their nests. Also, a far more environmentally friendly solution that is also easier to apply would be to use ant baits but for outdoor use in the form of granules.

Simply spread the ant bait granules on your lawn and anywhere near the crazy ant nest (at least where you suspect them to be) and just wait for it to show results. It will do the trick relatively fast, as soon as the crazy ants start to pull the granules inside their nest.

Crazy Ants in Car: What Should You Do?

Crazy Ants in Car

Crazy ants usually invade a car only in the search for a food source. After the first time they enter the car, they leave a trail of pheromones behind them, so other ants can follow their trail.

For starters, you should check your car for any food leftovers, and do a thorough cleanup of the whole car. Crazy ants can easily sense the food even if it is in your car, so try to keep it as clean as possible. After you finish that, you should change the spot where you park the car, at least for some time. That way the ants will lose the pheromone trail for sure.

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