The answer to 'why is my bee infestation' is that you likely have a beehive or colony of bees that has taken up residence near or inside your home. Bees may be attracted to your property for a few common reasons, such as easy access to food sources, water, or suitable nesting sites.
Some key signs of a bee infestation include seeing large numbers of bees flying around your home, hearing buzzing noises, or spotting an actual beehive or nest. Bees can establish colonies in tree cavities, attics, wall voids, or other sheltered areas around your property. While bees are generally not aggressive unless provoked, a large infestation can pose safety risks, especially for those with bee allergies.
