Quite often bees will display some preliminary defensive behavior before going into a full-fledged attack. Bees are generally very docile as they go about their normal activities. As the number of Africanized bee colonies increases in an area, so, too, does the likelihood of human and animal encounters with them. Serious human injury can be avoided if the habits of Africanized bees are learned and precautions taken. Wear light-colored clothing.
Bees tend to attack dark things.
Bees are sensitive to odors, both pleasant and unpleasant. The smell of newly cut grass has been shown to disturb honey bees. Avoid wearing floral or citrus aftershaves or perfume. Check your house and yard at least once a month to see if there are any signs of bees taking up residence. If you do find a swarm or colony, leave it be and keep family and pets away.
