I ate a banana this morning at 6:30. Then spent time cleaning up the backyard and around the beehives even ran the leaf blower with no problems. At 10:30 I decided to take a video of the bees washboarding around the hive entrance (something I've done many times before without consequence). As soon as the camera got close to the hive entrance bees started attacking it and me. Could that have been because the banana smell was still on me? The hive looks healthy and has never been aggressive up to this point.
