Thank you for reaching out! I don't see a hive in the photo you attached. I see an insect in the photo, but it's too blurry for me to identify. Can you please send more photos that show the bees/hives or describe them in detail? Recommendations for bee removal will depend on what kind of bee you have.

Thanks again for sending photos. The bees pictured look like a solitary bee species that emerge in the spring. Solitary bees normally lay eggs in stems or in tunnels in the ground, so I wonder if there were stems or ground nearby with developing bees or if the patio furniture provided a similar structure. Solitary bees tend to not sting people, and since they are solitary they don't live together as a family/colony. I expect that you can just wait a few days, and the bees will disperse. If you continue seeing the bees or have additional concerns, feel free to reach out. Thanks for looking after the bees!
