Summarize the following:
Go online and search for beekeepers in your area. Call each beekeeper to see if they are interested in the hive, even if they don’t mention picking them up on their website. Beekeepers are experienced in safely removing bees without killing them and will happily relocate them. There are also nonprofit bee removal services that keep bees from becoming endangered in high-risk areas where their pollination skills are especially important. You normally won’t need to pay a beekeeper to remove a hive. If you do, the fee won’t be particularly high, although it depends on where you live. If there are no beekeepers or nonprofit groups in your area, call a bee removal service. You will have to pay to have the bees removed, but a bee removal service will remove the bees safely and thoroughly. Bee removal experts often sell or give away their hives and will not kill the bees unless absolutely necessary. If the hive is easily accessed and the swarm isn’t particularly big, bee removal will cost $75-200. If drywall needs to be removed or the hive is in a tricky location, like a roof, it may cost up to $1,500. If removing the bees is not an option because the colony is inaccessible, contact a local exterminator. This is the worst option, since bees are good for the environment and the chemicals in commercial bee pesticides can damage a home, but you can certainly hire an exterminator to kill the bees if it’s the only way to have them removed.  An exterminator will cost roughly $200-300, but a new colony is more likely to return if the exterminator doesn’t remove the hive or handle it properly. Make sure that you hire an exterminator with experience removing bees. If a large number of bees die and their corpses are not removed, they will break down and leave a particularly funky odor behind that will take some time to get rid of.

Summary:
Contact a local beekeeper or nonprofit group first. Reach out to a bee removal service if you can’t find a local beekeeper. Contact an exterminator if the hive can’t be removed.
