And, if they were using fire you can be sure they would be using smoke to ‘calm’ the bees millenia before being depicted doing so in Egyptian hieroglyphs ~5,000 years ago. Bees often detect the pheromones of these predators when they are in the vicinity. They release pheromones which lets the other bees know that there is a potential danger. As a result, more bees may join the fight. I strongly suspect movement and vibration trigger defensive responses to a much greater extent than the detection of fear pheromones in humans (if they’re detected at all). I rarely if ever get an aggressive response. I certainly never achieve the sort of Zen-like state (or anything close) seen if you accompany a bee inspector or good beefarmer, where they can ‘read’ the hive almost without opening it, but at least I have something to aspire to in my beekeeping 🙂. In the same vein, there is a common saying that bees can smell fear. Insect anatomy is starkly different from what is familiar—some bugs have many more appendages, eyes, or other body parts than humans. 11. After all, they experience millions of different – and largely harmless – smells every day. The answer to that is they can smell the pheromones which are released after an animal experiences fear. Finally, we know that bees can detect and respond to a wide range of other smells. It means that it is tough for the dog or cat to disturb the bees directly. Being attacked by a swarm of bees would reduce approximately 100% of people into a state of flailing panic, but it’s not our terror that attracts them. At over 200 kg and standing 2+ metres tall I doubt they’re afraid of anything. Honey hunting tends to be destructive and results in the demise of the colony – the tree is felled, the brood nest is ripped apart, the stores (and often the brood) are consumed. However, some individuals believe that they can detect fear, as well. With their keen sense of smell, they will be alert in advance and therefore, your dog or cat might not be able to bring down the beehive since they will experience the attack before that. When they do, they tend to attack as they anticipate that their hive will be disturbed.

That is why, once a single bee detects the fear or the pheromones generated as a result of fear, they can easily communicate with each other. “That’s an aggressive colony. Instead of detecting fear in others conventionally through sight as humans may do, Bees can sense fear with the help of pheromones produced by animals when they are afraid. A lot of the above is half-baked speculation interspersed with a smattering of evolutionary theory. But we’ve exploited bees for tens or hundreds of thousands of years more than that. Yes, Bees can smell fear. The traditional predators like wasps and yellow jackets might arrive in no time after gaining the smell. Believe me, you’re not worth it. So, while we don’t know that bees could detect a fear pheromone, there’s a good chance that they should be able to. I presume this is evolutionary pressure due to bears. For example Graham Turnbull and his research team in St Andrews, in collaborative studies with Croatian beekeepers, are training bees to detect landmines 10 from the faintest ‘whiff’ of TNT they produce.

Mellivora capensis – the honey badger. They have an extremely sensitive sense of smell, reflected in their ability to detect certain molecules as dilute as one or two parts per trillion. Different odorant receptors have different specificities, binding and responding to the molecules that are present in one or more odours. From my understanding these two statements are mutually exclusive. Pheromones are produced in the body of any animal when they are scared. However, it is less sensitive in humans, while a study found that such fear can be contagious due to its smell, but humans cannot decipher it. Even relatively experienced beekeepers may be apprehensive when inspecting a very defensive colony. Although this might have been due to differences in the production of fear pheromones, it’s clear that the bees are also using other senses to detect potential threats to the colony. You’re not the first person I’ve heard of that talks to their bees. I’ve noticed inconsistent responses to smells, some said to trigger bees. The robbing process escalates quickly. Epigenetics?

They can get aggressive and start attacking the beekeeper. In a rather self-fulfilling manner we don’t know if bees have evolved a defensive response to the fear pheromone of humans as – for reasons elaborated above – we don’t actually know whether they do respond to the fear pheromone. Bees are very sensitive to the way people behave so if you act calmly rather than running around and slapping your hand around you are less likely to be stung or frighten a bee. So can Bees really smell fear? If things go well this apprehension disappears, immediately or over time as their experience increases. To conduct this study in a scientifically-controlled manner you would need to know precisely what the pheromone was. Bees can identify the scent of fear from humans. Graham Turnbull and his research team in St Andrews, 2004 Nobel Prize in Physiology or Medicine. Feeling threatened, humans tend to experience different physiological changes. Bees are also easier to train, according to Dr. Nesbit and are cheaper than sniffer dogs. To focus on them, and them alone.

It alerts the other bees that there is danger around the beehive. However, the fear of bee attacks has made people believe that bees can smell fear directly.

If things go badly they might develop melissophobia and stop beekeeping altogether. Is it true that bees can smell fear?
