Africanized honey bees earned their "killer bee" nickname for a reason; they're fiercely protective and surprisingly persistent. Knowing what makes them tick can help you stay safe and protect your property.
Africanized honey bees (Apis mellifera scutellata) are a hybrid between the African and European honey bee subspecies. First introduced to Brazil in 1956, they've since spread throughout South and Central America, reaching the southern United States in 1990. These bees are slightly smaller than European honey bees but are known for their heightened defensive behavior and rapid reproduction. According to the USDA, they've been confirmed in nine US states.

To help identify Africanized honey bees, read on to learn more about their biology and behavior patterns, which differ significantly from European honey bees in several key ways.
The Africanized honey bee’s habitat is notably diverse compared to that of European honey bees, and that's part of what makes them tricky. These bees aren't picky about real estate. They'll establish colonies in water meter boxes, overturned flower pots, empty containers, abandoned vehicles, and even underground in animal burrows. This flexibility in choosing nesting sites means you're more likely to stumble across them unexpectedly.
In urban and suburban areas, they may occupy wall voids, attics, or gaps in building structures. They thrive in warm climates and can spread northward at a rate of 200 to 300 miles per year.
Like all honey bees, Africanized honey bees feed on nectar and pollen from flowering plants, and they’re actually effective pollinators. What sets them apart is their work ethic: they begin foraging at younger ages than European honey bees and harvest greater quantities of pollen to support their higher reproductive rate.
Africanized honey bees are also less selective, foraging on a wider variety of resources, including water, pollen, and unconcentrated nectar. This aggressive foraging behavior helps them thrive in tropical environments where food sources may be less concentrated.
The Africanized honey bee’s life cycle is similar to that of other honey bee subspecies. Worker bees develop in 19-20 days compared to 21 days for European bees. Queens can lay up to 1,500 eggs per day during peak season, contributing to quick colony expansion. Colonies reproduce through swarming, when the queen and a portion of workers leave to establish a new colony.
Africanized bees swarm more frequently than European bees, sometimes multiple times per year. They also practice "absconding," where the entire colony abandons the hive in response to food shortages or disturbances.
Africanized honey bee characteristics include heightened defensiveness and hair-trigger responses to perceived threats. They station more guard bees around the hive and maintain a larger alarm zone, sometimes defending from distances up to 100 yards compared to 1-20 yards for European bees. When disturbed, they can pursue perceived threats for up to 400 meters (1,300 feet). That's roughly four football fields.
They respond to disturbances faster and remain agitated longer after the initial threat has passed. This makes them particularly dangerous, and is why you should never attempt to remove a colony yourself.
Recognizing an Africanized honey bee presence early can help you avoid a painful encounter. Key warning signs include:
Unlike European honey bees that typically ignore passersby, Africanized bees stay on high alert. Never attempt to investigate or remove a suspected colony yourself. If you suspect Africanized honey bees on your property, contact us for professional bee control immediately to safely address the situation.
Dealing with Africanized honey bees requires professional expertise. Whether it’s a commercial or residential setting, our technicians are trained to safely handle bee infestations while following all regulations. We assess each situation individually, whether that calls for safe removal, relocation with local beekeepers, or treatment when colonies pose a genuine threat.
Don't risk DIY bee removal. Africanized honey bees become extremely aggressive when threatened.
Yes, like all honey bees, each Africanized bee can only sting once before dying. The real danger isn't the individual sting; it's in the sheer number of bees that can attack at once. Victims can receive hundreds of stings during an attack compared to a dozen or so from European bees.
Africanized honey bees are highly defensive of their colonies. They have more guard bees, respond to threats faster, and pursue perceived dangers much farther than European honey bees. Vibrations, loud noises, dark colors, and certain scents can all trigger their defensive response.
Visual identification is nearly impossible for non-experts, as they look very similar to European honey bees. Behavioral clues help: unusually defensive colonies, frequent swarming, nesting in odd locations, or aggressive responses to minor disturbances.
