Wasps are one of the most beneficial insects known besides bees
Only the female wasp can sting and is often the most territorial considering she is protecting her nest from predators, which they think we are when we disturb them. There are a variety of species of wasps that include both flying and non-flying wasps, such as the calf killer wasp. This wasp is often thought to be in the ant family but actually is a wasp.
Wasps are not protected and they can be treated. However, since wasps do fly, control of wasps is difficult at times especially if the nest is not accessible.
