Why Wasps Are Dangerous Species?


Contrary to popular belief, most of the 20,000 species of wasps that are known, are solitary. However, with that sad, it’s also worth noting that some species of wasps are particularly dangerous and should be avoided at all cost. In this overview, we’ll take a look at what species of wasps are dangerous as well as the reasons why wasps are dangerous species.

1)Yellow Jackets

Yellow Jackets are heavy bodied wasps who have a distinctive black and yellow marking. They are also categorized as being the most aggressive of all wasp species. This is due to the fact that they are highly defensive. Unlike other aggressive wasps, who will only attack if their nests are physically disturbed. Yellow Jackets on the other hand, attack anyone or thing that is within close proximity of their nest. Worse yet, something as simple as a loud, low frequency noise from a power lawn equipment for example, can aggravate these wasps and cause them to attack. Another aspect of these types of wasps that make them dangerous, is their sheer size and the fact that they are categorized as being a social insect, which means that they can communicate with each other and thus, coordinate a strategic response to any invader, as to wish they will continuously sting as long as they are within close proximity of the nest.

2) Paper Wasps

Paper wasps in general are not usually aggressive. However, if they nests are disturbed, they tend to attack the intruder in swarms. It’s also worth noting, that while their stings are painful, yet not lethal, certain individuals may experience a lethal allergic reaction, known as anaphylactic shock.

3) Hornets

Hornets are yet another dangerous species of wasps that are categorized as being a social insect as well. What makes this specie so dangerous is the fact that they use pheromones to transmit communication signals, to the entire nest. This in turn, causes them to swarm a perceived intruder. Another aspect that makes this specie dangerous is that the venom within its singer contains a chemical called acetylcholine. In small doses this is relatively harmless, but if an entire swarm concentrates it attack on a human being, the concentration on of that type of chemical will be significantly higher within their bloodstream and thus, more harmful. To put things in retrospect, someone who has a high concentration of acetylcholine within their blood stream may experience:

  • Oedema of the Eye
  • Slower Heart Rate
  • Blurred vision
  • Mental Fatigue
  • Muscle pain
  • Tingling or numbness of the arms and legs
