Not before they do significant damage. Once bees live in a wall or in an attic they will usually stay. The bees will make a honeycomb in the wall and up in the attic. Honeycombs will not go away on their own. Once the bees are removed, the honeycomb needs to be removed as well.

A honey bee hive will make a honeycomb fairly quickly. The rate at which the honeycomb is made depends on the size of the bee hive and if they are European honey bees or Africanized honey bees. Africanized honey bees were genetically created for their fast production of honey.

The honey from bees will do significant damage in your attic and can be very expensive if it is not removed. The longer the bees have to live in the attic the more time they have to create a honeycomb. Honeycombs attract roaches and rats and will ruin drywall. Honey bee removal is essential to prevent costly damage in the attic and prevent pests from invading the home.
