Bees are used to pollinate the trees. As they fly from flower to flower, from tree to tree, pollen attached to the bees is transferred between trees which pollinates them, allowing them to produce fruit.
A 'hive' is an artificial home for bees provided by a beekeeper. Bees living wild in a tree would normally be described as a colony.
Flies and bees
Bees pollinate individual blossoms on a tree so it would need a colony of bees (up to 80000) to pollinate a whole tree.
If a swarm of bees makes a home in a tree in your garden, you can telephone a bee keeper to take the colony to another hive.
There are two ways to repel carpenter bees. The first is to spray the tree with citrus extract, and the second is to spray with almond oil or extract.
