If the bees are inaccessible, you will need to contact a pest controller who will have the necessary chemicals.
Get a bee professionally trained bee Keeper to open the fan and try and get out the bee then put the fan back.
Contact a bee keeper they will likely remove them for free because the bee population has Dwindled down to 3% to what they used to be. Only other option is to kill them with raid or similar insect killer.

In order to get rid of a ground nesting bee hole, it's important to create an environment the insects don't like. The bees are attracted to dry land, so watering the yard and nest will be beneficial in getting them to leave. Insecticides should be avoided since bees populations are decreasing around the world.
Call a bee keeper. Bees are not usually a pest but are valuable for continued preservation of the Earth's survival. Without them we will eventually starve. A bee keeper will capture the queen of the hive and take them to a more acceptable place to live. Extermination will likely do more damage to you than the bees and removal should only be done by someone who knows what they are doing. Bees are only a danger to any person who has an allergy to bee stings and will help your garden to thrive.
If it is a hive - rather than a nest - then just contact your local beekeeper association (find via the BBKA website). It will need to be moved at least 3 miles from its present location or bees will return to wherever it is currently. If it is actually a bee swarm or nest then contact a swarm co-ordinator in your area (again check the BBKA website to find them). They will be able to check the type of bee and advise or act accordingly.
You should get rid of the nest because wasps will be atracted to the honey and if there are wasps they probably won't sting you as they are stealing and remove the nest at night as that is when wasps bees and other insects go back to their hives, but be careful.
