Therefore, the best way to eliminate these bees is to cover outdoor food and use bee-protective hummingbird feeders. If they're still considered to be nuisance animals or someone in your family has a bee allergy, it might be best to call a pest control company.

Although no one can predict whether bees will leave on their own, a good rule of thumb is that the longer the bees stay, the less likely they are to leave. Once they have started building hive material, they are less likely to abandon their home. When bees are just resting, they usually take flight within 24 hours.

Swarms are temporary and the bees will move on if you patiently ignore them. Stay back and keep others away from the swarm, but feel free to admire and appreciate the bees from a safe distance. You may be able to give a honey bee swarm to a beekeeper who will gather the swarm and relocate it for you.
