Wasp are territorial and aggressive. Since they feel an imminent threat to them or their nest, the entire colony will attack to keep the intrude out. Wasp can sting multiple times and the stinger contains venom. It can be dangerous and deadly if someone is allergic to wasp stings. So compared to bees, wasps are more harmful.
Actually, bees and wasps sting humans only for self-defense or to protect their colonies. To prevent from the sting, you need to stay away from their nest and not to provoke them. If you notice a beehive or wasp nest at your home, please contact a pest control professional to handle the problem.
