Is killer bee venom deadly

The sting of the Africanised Honey Bee (Killer bee) is no more potent than another variety of honey bee.

What makes them more dangerous is that they are more easily provoked, quick to swarm, attack in greater numbers, and pursue their victims for greater distances.

So, it is not deadly in a single sting, but with multiple stings it can be deadly but no more than any other honey bee.

Of course, if you're allergic to bee venom, even a single sting could be deadly.
