The answer to 'why is my bee invasion' is that you likely have a bee nest or hive near your home. Bees may be attracted to your property for a few common reasons, such as readily available food sources like flowering plants or fruit trees, or a suitable nesting site like wall voids, attics, or sheds. Bee infestations can happen when a swarm of bees finds a new location to establish a colony.
Signs of a bee invasion include seeing a large number of bees coming and going from a specific area, hearing buzzing noises, or noticing bees entering and exiting cracks or openings in your home's exterior. While bees play an important role in pollination, a large bee colony can pose risks to you and your family, especially if anyone has bee allergies.
