How Do Ants Communicate? (Explained)

Ants, although small and seemingly insignificant, have a complex and intricate way of communicating with one another. In this fascinating article, the Wildlife Informer explores how ants utilize pheromones, touch, and even sound to convey information and maintain the organization within their colonies. From marking trails to alerting others of danger, ants have developed an impressive system of communication that showcases their remarkable abilities. With each new discovery, scientists uncover more about the intricate world of ant communication, and the more they learn, the more astonishing ants become.

How Do Ants Communicate?

Ants are fascinating creatures with a complex social structure and a diligent work ethic. To achieve organization within their nests, ants rely on communication. While ants do not communicate in the same way humans do, they have developed various methods to convey information to each other.

Do Ants Communicate With Each Other?

Ants communicate through a combination of pheromones, touch, and sound. Pheromones are chemical signals that ants secrete to relay messages to other ants. They can also communicate by touching their antennae together, which allows them to feel and smell each other. Additionally, ants can produce sounds by rubbing parts of their abdomen or using specialized abdominal spikes.

How Do Ants Use Pheromones To Communicate?

Pheromones play a crucial role in ant communication. Ants use pheromones in several ways to convey a wide range of information.

  • Using Pheromones to Find Food Sources: Forager ants leave pheromone trails as they search for food. Other ants can follow these trails to locate food sources and establish organized lines of ants to collect food.
  • Regulating Foraging Efforts: Ants use pheromones to coordinate foraging activities within the colony. By using specific pheromones, they can control the number of ants involved in foraging and adjust their efforts accordingly.
  • Creating Memories of Good Food Supply Areas: Pheromones can also be used to create memories of locations with abundant food supplies. This allows ants to revisit these areas in the future and optimize their foraging efforts.
  • Selecting Different Foods According to Nutrient Needs: Different types of ants may require specific nutrients. Ants use pheromones to indicate which food sources are suitable based on the nutritional needs of the colony.
  • Conveying Information on Food Source Locations: Ants can communicate the location of food sources to other members of the colony through the use of pheromones. This information helps ensure efficient food collection.
  • Indicating Nest Identity, Social Status, and Maturity: Pheromones can be used to identify the nest a particular ant belongs to, convey social status within the colony, and indicate the maturity level of individual ants.
  • Signaling Mating Availability and Queen Aging: The queen ant uses pheromones to signal her readiness to mate, attracting male drones. As the queen ages, she releases pheromones that indicate her declining condition, prompting the colony to prepare a new queen.
  • Releasing Alarm Pheromones to Alert to Danger: When ants encounter a threat or danger, they release alarm pheromones to alert the rest of the colony. This helps mobilize a collective response to protect the nest.

Do Ants Communicate By Kissing?

While it may appear that ants are kissing when they touch their mouths together, they are actually engaging in a behavior called trophallaxis. During trophallaxis, ants regurgitate food and share it with other ants in the colony. Along with the food, ants transfer hormones and other chemicals that carry information.

Do Ants Communicate Using Sound?

Contrary to popular belief, ants can produce sounds to communicate with each other. The sounds they make are called stridulations and vary depending on the ant species.

  • Ants’ Stridulations and How They Are Produced: Some ants produce sound by rubbing two parts of their abdomens together. Other species, such as Myrmica ants, have specialized ridged spikes on their abdomen which they stroke with their hind legs to create a unique sound.
  • Social Significance of Ant Stridulations: Ant stridulations play a crucial role in social communication among ants. They are often used to convey warnings or alarm signals, indicating the need for urgent help.
  • Worker Ants’ Acoustic Messages and Alarm Calls: Worker ants use specific acoustic messages to communicate with each other. When an ant produces a stridulation as an alarm call, it triggers a response from nearby worker ants, who rush to aid the individual in distress.

Do Ant Pupae Communicate?

Traditionally, it was believed that pupae, the developmental stage between larvae and adult ants, were silent and did not communicate. However, a study conducted in 2013 revealed that mature pupae can produce sounds similar to adult ants.

  • Pupae Sound Production and Response of Adult Ants: As pupae mature and their exoskeletons harden, they develop a ridged spike on their abdomen. Sound recordings have shown that mature pupae can produce acoustic noises similar to those of adult ants.
  • Mature Pupae Calling for Help and Mimicking Queen Ant’s Noises: These stridulations emitted by the mature pupae appear to be calling for help. Adult ants respond by clustering around the pupae, providing them with additional food and protection. Some pupae even produce stridulations that mimic the sounds of a queen ant, indicating their potential to become the next queen within the colony.

Insects Eavesdrop On Ants’ Communication

In a fascinating discovery, it has been found that insects, including ants from other nests, different species of ants, other insects, and predators, eavesdrop on the communication of ants. These insects detect and follow pheromone trails left by ants, ultimately hijacking their food sources. Predators may even use pheromone trails to locate ant nests and raid them for larvae, pupae, or adult ants.


Ants are remarkable communicators, utilizing a combination of pheromones, touch, and sound to convey information to each other. Through these various methods, ants establish organized lines for food collection, regulate foraging efforts, convey social status and maturity, and even sound alarms in the face of danger. Their sophisticated communication skills and social structure contribute to their success as a species.
