If it is an emergency or anyone is in immediate danger call 911.
Although most bees are not extremely defensive any hive may become agitated when exposed to loud noises such as lawnmowers, chainsaws, barking dogs Etc.
After making sure no one is in immediate danger you may wish to contact a beekeeper for their recommendations. You are encouraged to contact several beekeepers for information on any fees they may charge for their services.
The City of Brownwood does not endorse any particular beekeeper.
