The answer to a bee infestation is to first determine the type of bees and the extent of the infestation. Bees can be beneficial pollinators, so it's important to avoid harming them if possible. Common causes of bee infestations include swarming, a nearby hive, or the bees nesting in the home's walls or attic.
Symptoms of a bee infestation include seeing a large number of bees around the home, hearing buzzing sounds, or spotting a hive or nest. Solutions depend on the situation, but may include sealing entry points, removing the hive, or using targeted pesticides. In many cases, it's best to call a professional pest control technician, especially for larger infestations or if the bees are nesting inside the home's structure.
