Aside from secreting honey and being industrious insects, another trait that makes bees popular is their sense of smell. They use this for communication, to sense things, and to find food. This enhanced sense of smell makes human beings curious about bees. Can bees smell fear?Why do bees attack people who are afraid of them? What happens when bees sense fear? This article answers these questions, serving up all you need to know about how bees use their olfactory sense.
Can Bees Smell Fear?
Bees, amidst other insects, stand out for their keen sense of smell. Bees use this sense of smell for communication and to find survival food. They use smell to detect predators and threats to the beehive. They do this by differentiating pheromones and determining which one indicates a threat, hunger, or aggression towards their hive.
Due to bees’ evolved sense of smell, people believe they sense or detect fear. Even from childhood, people around you might have mentioned that bees can smell fear.
But can bees smell fear? The short answer to this is no.
Bees can’t really smell fear. What bees smell is the release of pheromones that takes place when an animal or human is feeling fearful. Bees interpret the smell of these pheromones as a threat. Then, they react accordingly to the pheromones and signal to other bees within range.
Bees don’t smell fear. However, they detect fear pheromones released when an animal or human is afraid. Essentially, their olfactory system enables them to collect scents and establish their meaning. So, even though they don’t smell fear directly, they have a keen sense of smell for perceived threats.

How Do Bees Detect Fear?
Creatures and human beings produce fear pheromones when scared. In humans, the mouth's palate detects the smell molecules from pheromones and transfers them to the limbic system. This is the part of the brain that deals with emotional responses.
Generally, the fear pheromones that creatures produce can only be detected by the same species. However, bees are an exception to this rule. Bees can detect pheromones of other species.
Since bees communicate using smell signals, the other honey bees quickly get notified through the smell. In a short while, the entire hive learns of the smell. They use this pheromone detection to protect themselves against predators in advance. Bees can either become defensive or aggressive when they detect a strange pheromone.
How Do Bees Communicate with One Another?
A hive is a busy place with thousands of bees confined in one place. A single colony of bees can consist of over 10,000 bees. There are many roles within the colony, ranging from the queen bee to worker bees, such as cleaners, nurses, builders, guards, and so on. With this kind of population and roles, there is a need for efficient means of communication.
Bees don’t only communicate with chemical signaling or pheromones. They also communicate using physical behavior. Physical actions allow communication within small groups of bees.
Pheromones enable communication among bees broadly and even quickly. They use smells effectively for wide ranges and allow swift communication, especially when they detect threats. Communication among bees can be classified into two they are :
1. Physical Behaviour
Humans adopt body language to communicate simultaneously with words, body language, or signs alone. Bees also are experts in using body language to communicate. Furthermore, they are experts at interpretive dances.
In simple terms, physical behavior is the body movement that small groups of bees use for communication. The duration of the movement and its direction, even with the vibration of the bee's body during the movement, contribute a lot to the message. Bees have three main types of dance they use to communicate.
- The Waggle Dance
- The Round Dance
- The Vibration Dance
The Waggle Dance
A bee researcher, Karl Von Frisch, discovered this dance in the 1940s through an experiment. Here, the bee dances in a figure eight, with the angle of the figure eight suggesting the direction of the food source in relation to the sun.
The speed of the bee's abdomen waggle during the dance indicates the distance to the food source. The amazing thing about this is that the dance performance is usually in a dark environment.
The Round Dance
The round dance communicates the location of food sources within a close range. The location range should be around 100 meters (338 feet) from the hive. Waggle Dance takes care of any food source location farther than this. It doesn't show directions.
The Vibration Dance
The essence of this dance is a call to action. For this dance, bees in the hive vibrate their bodies, which transmits through the surrounding wax comb. It’s a signal to other bees for the availability of forage for foraging bees.
Some other types of bee dances include the whir dance, massage dance, joy dance, shake dance, and alarm dance.
2. Pheromones
The other way for a bee to communicate with other bees is through its pheromones. A pheromone is a chemical substance produced and released into the environment by animals. This is especially true for mammals or insects, affecting the behavior or physiology of other species.
Bees have a highly developed sense of smell in their antennae. This allows for the rapid processing of pheromone messages. These pheromones not only instigate physical actions from the bees but also affect the physiology of the bee's body. When a bee stings, it releases an alarm pheromone. Essentially, this alerts other bees in the hive, prompting them to join forces to attack. Setting off the pheromone alarm rests primarily in the hands of guard bees protecting the hive.
Why Do Bees Attack People?
The fear of bees, apiphobia, is common among many people. Most people start to lurch, swatting or jerking at the mere sight of bees or even the buzzing sound. At that instant, human beings panic and become fearful.

When humans or other animals are scared, we release the fear pheromone. Consequently, bees can smell these chemicals our bodies release. Individual bees that detect the fear pheromone communicate quickly to alert bees nearby about the threat.
Bees defend their hive to protect their space. Therefore, they attack people when they feel threatened. As a result, their fellow bees come around to protect their territory.
Although bees are compliant creatures that only attack when they feel threatened, some different types of bee species are highly aggressive.
The Africanized Honeybee, known as the Killer Bee, is extraordinarily aggressive and quick to chase people and attack. Research shows that this bee species has been responsible for the death of around 1000 people since its introduction to Brazil. On the other hand, the regular honey bee stings only as a last resort and when it senses a threat to its colony.
How to Avoid Bee Attack
Most bees are harmless and will only attack if they’re feeling threatened. This omits species like the Africanized honey bee that’s quick to attack. Rather than attacking, bees prefer the threat to leave quietly.
Therefore, the best way to avoid a bee attack is to remain calm and avoid sudden movements. A sting is like suicide for bees. Once bees sting, they will die as they can’t pull their stinger out without self-amputating. No one wants to be stung by a bee, or at least not again if it occurred previously. The following are ways to avoid bee attacks or bee stings:
- If you’re scared of bees, your instinct when you see one may be to swat it. But this only makes the bees see you as a threat. Bees pick up jerky movements quickly and are more likely to sting people making movements. As a result, it encourages them to sting. Avoid swatting, jerking, and any unsteady movements. Stay calm and wait for the bee to leave.
- Bees usually attack the face and head of their victim. Cover your head and face with available materials.
- Move away as fast as possible if you sense bees coming toward you. Bees back off once they no longer see you as a threat to their colony.
- Hide or seek shelter in a covered place and avoid jumping into a body of water. Bees simply wait for their victims to surface when seeking refuge in water.
Conclusion
Although most people believe that bees can smell fear directly, we’ve explored the true meaning behind their sense of smell. Bees smell chemicals we produce as a result of fear.
Unfortunately for humans, bees perceive these pheromones as a threat, making them attack. They can invite more bees to sting the perceived threat through chemical signaling. At the sight of bees, ignore that impulse to swat. Instead, stay calm and follow the steps above. This will help you avoid bee attacks from other bees nearby.
