Honey bees are one of the singularly most important insects on earth, without which many plant species would not be able to survive as honey bees play a crucial role in pollination. Sometimes honey bees build nests in areas in which they will pose a danger to humans. In this situation, the first step is to call a professional to see if they can relocate the hive. When all else fails, there are simple ways to kill honey bees if no other option is available.
Spray singular bees, or even swarming bees with a commercial bee, wasp and hornet killer spray, while wearing the bee suit. Never spray a hive entrance, as this will anger, rather than kill, the bees inside and make them aggressive, Moreover, if the hive is attached to a house, chances are you will have a lot of bees in the house afterward.
Put on the bee suit, and get close to the entrance of the hive. Sprinkle borax powder around the entrance of the hive, so that any bee coming or going from the hive will come in contact with the powder. The borax is a slow but sure method of exterminating a hive, especially good for those built into sidings or eaves.
Wait two or three days, periodically checking the hive activity. The bees entering the hive will take the borax dust inside with them, eventually poisoning the whole hive. Clean all the remnants of the hive out once all the bees are dead.
Never attempt to exterminate a hive of Africanised, or so-called 'killer' bees. These bees are similar to regular honey bees, but are extremely aggressive,= and intolerant of any activity near their hive. They are known to chase people up to 150 feet from the hive, and will even wait above a swimming pool if you jump in to try and escape them. Always call a professional in case of killer bees. Always wear protective clothing when killing bees. Always clean out the remnants of a hive, otherwise it will attract other pests as it decays, and the honey ferments. Never eat honey from a hive from which you have killed the bees. The honey will be contaminated with the poisons used to kill the bees.
