The answer to 'why is my bee infestation' is that you may have a hive or nest of bees located on your property. Bees are typically drawn to areas with abundant nectar and pollen sources, such as flowering plants, trees, or gardens. They may build their hive in a secluded spot like the eaves of your home, a tree hollow, or even in the ground.
Signs of a bee infestation include seeing a large number of bees flying around, hearing buzzing sounds, or noticing a hive or nest structure. Bees can become aggressive if their hive is threatened, so it's important to address the issue promptly and safely.
