The answer to 'bee swarms' is that bee swarms are a natural occurrence when a honey bee colony reproduces. This usually happens in the spring when a queen bee leaves the hive with a large group of worker bees to find a new home. Bee swarms are generally not aggressive and do not have a hive to defend, but they can be alarming to see. The best solution is to avoid disturbing the swarm and contact a professional beekeeper or pest control expert to safely remove it.
Bee swarms can happen suddenly and unexpectedly, often clustering on tree branches, fences, or the sides of buildings. The swarm is usually made up of thousands of bees and can appear intimidating, but they are typically not interested in stinging unless provoked. Attempting to remove a swarm yourself is not recommended, as you could risk being stung multiple times. Calling in a professional beekeeper or pest control technician is the safest option to have the swarm removed and relocated to a new hive location.
