Spanish scientists accidentally discovered that bees have a superior sense of smell. Bees have a more sensitive sense of smell than dogs and are particularly sensitive to the smell of gunpowder. They are currently studying the feasibility of using bees to search for bombs instead of dogs.

Bees have a more sensitive sense of smell than dogs

Scientists use bees and dogs to compete in fetch-and-find competition. The data obtained showed that the memory time of bees for smells is 30 minutes, while the memory time of dogs for smells is only 7 minutes. Dogs’ olfactory sensitivity decreases in hot or cold weather, but bees do not.

It was previously reported that it usually takes six months to train a detection dog, but training a bee is much faster.

The training method is to place bombs and sugar water to be detected in front of the bees. When the bees suck the sugar water, they will smell the smell of sugar water and bombs or chemicals at the same time.

After training, it was shown that if bees smell the smell of bombs, they will mistake it for sugar water and fly over. Even though it is only a slight smell, it cannot escape their sensitive sense of smell. On the other hand, beekeeping is less expensive than keeping a dog. Therefore, scientists are further studying the feasibility of using bees to search for bombs instead of dogs.
