The answer to 'why is my wasp swarms' is that you likely have a wasp nest or hive near your home. Wasps are social insects that live in colonies, and when their population grows, they may build a new nest or swarm to establish a new colony. This can happen when their existing nest becomes overcrowded or they need to find a new location to build their next nest.
Common causes of wasp swarms include warm weather, availability of food sources, and the natural life cycle of the colony. Symptoms may include seeing large numbers of wasps flying around your home, hearing buzzing noises, or noticing a nest or hive. Solutions can include removing the nest, using insecticides, or calling a professional pest control technician to properly eliminate the wasp colony.
