The answer to 'why do I have bees' is that you likely have a beehive or nest near your home. Bees are attracted to areas with ample food sources, such as flowering plants, trees, and gardens. They may build their hive in the walls, attic, or other secluded areas of your home.
Common signs of a bee problem include seeing bees entering and exiting a specific area, hearing buzzing noises, or noticing honeycomb or wax buildup. If left untreated, a bee infestation can grow rapidly and become a serious issue. While bees are generally not aggressive unless provoked, their stings can be dangerous for those with allergies.
