Hornets are large stinging insects that belong to the genus Vespa. There are many species of hornets found worldwide, including in Nepal. While they are beneficial for the ecosystem, they can pose a danger to humans, especially those who are allergic to their venom. Hornets are generally not aggressive and will only attack when they or their nest feel threatened. To avoid getting stung by a hornet, it's best to stay away from their nests and not disturb them. If you do come across a hornet's nest, it's important to remain calm and move away slowly without swatting or making sudden movements. If you do get stung by a hornet, remove the stinger and wash the affected area with soap and water. Applying a cold compress can help alleviate pain and swelling. Over-the-counter antihistamines and pain relievers can also help manage the symptoms. However, if you experience difficulty breathing, swelling in the throat or tongue, or other severe symptoms, seek medical attention immediately. It's also important to note that there are different species of hornets, some of which are more dangerous than others. The Asian giant hornet, for example, is known for its aggressive behavior and powerful sting, which can cause anaphylactic shock in some individuals. It's important to exercise caution and seek professional help when dealing with dangerous hornet species.
