I don't know you or how much experience you have w/ bees, but I wonder if it isn't the bees, but your experience? Perhaps you need more experience working bees or working around bees.
How are the bees expressing their aggressivness? How much experience do you have keeping bees? Do you have a smoker, veil, gloves, coveralls and hive tool? Do you know how to use them properly?
The reason I ask is that your question seems somewhat elementary(?). That of a newbee or novice. We all have to start some time.
