Whilst I have no experience of Africanised bees, we do sometimes get some very nasty bees in this country - usually where yellow and black bees cross. Some of these will meet you 50 yards from the apiary and follow for several hundred yards when you leave. The easiest way to find and remove the queen is to take off the supers and then move the brood box away - perhaps 20 yards - then leave them for ten minutes to calm down. The most agressive bees will now be back with the supers and it is usually very easy to find the queen in the now depleted brood box(es).
