Which type of wasp is known for its aggressiveness when defending its nest?

The Yellow jacket is known for its highly aggressive behavior, particularly when it comes to defending its nest. These wasps are social insects that build nests in a variety of locations, which can include underground burrows or hidden spots in buildings. When their nest is threatened, Yellow jackets are quick to perceive danger and will readily defend their territory.

Unlike other wasp species, such as the Paper wasp or Bald-faced hornet, Yellow jackets tend to be more protective and reactive, leading to more aggressive encounters. Their nests can also be large and densely populated, which contributes to their defensive nature. In addition, Yellow jackets can sting multiple times, which increases the threat they pose when they feel their nest is in jeopardy. Though the Cicada killer is also a type of wasp, it is solitary and doesn’t exhibit the same level of aggression since it doesn’t defend a communal nest.
