Yes, there will be some hanging around ... any foraging bee that was flying gathering pollen and nectar at the time the hive was destroyed, will make their way back to where the hive entrance was sited to bring back their food for the colony. They stick around for at least a day or two, but they cannot start a new colony without a queen bee.
the bees will make a new nest nearby
Bees are still around but they are slowly dying off because of a disease

I saw a swarm of bees hanging on a tree.
A colony when in a hive, or a swarm when hanging in a cluster from a tree branch.
Honey bees live in a colony of around 50,000 bees in the season so there are more of them when needed. Bumble bees might have only 50 bees in a nest but are still used when growing fruit in polytunnels.
They populations of these bees have been declining for years. Scientists say they believe the ones that are still around, have migrated to different parts of the world.
There is no evidence that Gregor Mendel created vicious bees. In fact he was unsuccessful at breeding them alltogether. This myth seems to have come about around 2001 in online publications and been copied without reference in unscrupulous sources.
because his pigs and bees felt extremely lonley!
It's not a queen bee; queen bees don't fly. The insect is apprently attracted to an aroma coming from your door. It might perceive that a food source is near.
To keep bees away from your dumpster, try sealing any food or liquid waste in airtight containers to prevent attracting them. You could also consider placing aromatic herbs or natural repellents like vinegar around the area to deter them. Additionally, regular cleaning and removing any spills promptly can help reduce bee activity near the dumpster.
To safely remove a resting swarm of bees hanging on a screen, it's best to contact a local beekeeper or professional bee removal service. Avoid disturbing the bees yourself as they may become agitated and sting. The beekeeper will be able to safely relocate the swarm without harming the bees.
