Africanized Bees in Texas: What You Need to Know in 2025
Africanized honeybees (killer bees) are established throughout most of Texas south of Abilene–Wichita Falls. They look identical to regular honeybees but are far more defensive — responding faster, with more bees, pursuing further. If attacked, run immediately to enclosed shelter. Do not jump in water. Texas beekeepers manage the risk by re-queening annually with certified European queens and inspecting regularly for unusual defensiveness.

What Are Africanized Bees?
Africanized honeybees are a hybrid of African honeybees (Apis mellifera scutellata) and various European honeybee subspecies. They were created in Brazil in the 1950s when African bees were imported for a honey production experiment. Some escaped in 1957 and have been spreading northward ever since — reaching Texas in 1990.
They are often called "killer bees" — a term that is somewhat misleading. Their venom is identical to regular European honeybees. What makes them dangerous is their extreme defensiveness:
- They respond to perceived threats 3–10 times faster than European bees
- They send 10 times more defenders to attack a threat
- They pursue threats for up to a quarter mile (400 metres)
- They remain agitated for hours after disturbance
- They guard a much larger zone around the colony
Africanized bees are dangerous because of the number of stings they inflict in an attack — not because their venom is stronger. A person can survive a few hundred stings; several thousand stings can be fatal. People with bee allergies face anaphylaxis risk from even a small number of stings regardless of bee type.
Where Are Africanized Bees in Texas?
Africanized honeybees are established throughout most of Texas. They were first confirmed in Hidalgo County (Rio Grande Valley) in 1990 and have since spread across the state.
- Confirmed presence: All of South Texas, Central Texas (including Austin and San Antonio metro areas), West Texas, and the Gulf Coast
- Detected northward: Dallas-Fort Worth area has recorded Africanized colonies
- Spreading boundary: A rough line from Abilene to Wichita Falls marks the approximate northern limit of established populations — though individual colonies are found further north
- Density: Africanized bees are most prevalent in South Texas and the Rio Grande Valley where the climate is warmest
If you live in Central or South Texas and encounter a wild bee swarm or colony on your property, treat it as potentially Africanized until proven otherwise. Do not approach, disturb, or attempt to remove it yourself — contact a professional beekeeper or pest control specialist.
How to Identify Africanized Bees
You cannot reliably identify Africanized bees by appearance alone. This is one of the most important facts Texas residents need to understand.
- Appearance: Africanized bees are virtually identical to European honeybees in size, colour, and body shape. Expert entomologists cannot tell them apart without laboratory testing.
- DNA testing: The only definitive identification method is laboratory DNA or morphometric analysis. Texas A&M AgriLife Extension offers bee identification services.
- Behavioural clues: Unusually aggressive response to minor disturbances, large numbers of bees pursuing a threat, and prolonged agitation after disturbance are strong behavioural indicators — but not proof.
In South and Central Texas, treat any unknown wild bee colony as potentially Africanized. This is the safest approach. If you need a colony assessed, contact a Texas certified beekeeper, your county extension office, or Texas A&M AgriLife Extension.
Africanized vs European Honeybees
European Honeybee
- Calm — tolerates disturbance well
- Responds with 10–20 defenders
- Pursues threat 50–100 metres
- Calms down within minutes
- Guards small zone around hive
- Safe for urban beekeeping
- Ideal for hobby beekeepers
Africanized Honeybee
- Extremely defensive — reacts to minor disturbances
- Responds with 100–1,000+ defenders
- Pursues threat up to 400 metres
- Remains agitated for hours
- Guards large zone — up to 50m from hive
- Dangerous in populated areas
- Requires professional management
Full protective suits are non-negotiable for beekeeping in South and Central Texas where Africanized bees are established.
What to Do If Attacked by Africanized Bees
🚨 Emergency Response — Africanized Bee Attack
- 1Run immediately. Do not stop to swat at bees — this triggers more attack. Cover your face with your shirt or jacket as you run.
- 2Run in a straight line away from the colony as fast as possible. Do not zigzag.
- 3Get inside a building or vehicle immediately. Close all doors and windows. Bees may follow you inside briefly but will leave.
- 4Do NOT jump into water. Africanized bees will hover at the surface and sting you when you come up for air.
- 5Do not stop running until you are inside enclosed shelter. Bees may pursue for up to 400 metres.
- 6Call 911 if anyone has been stung extensively, shows signs of allergic reaction, or cannot escape.
- 7Remove stingers by scraping sideways with a fingernail or credit card — do not squeeze or pull, which injects more venom.
- 8Seek medical attention if stung more than 15–20 times, or immediately if any signs of anaphylaxis (throat tightening, difficulty breathing, dizziness).
Prevention for Texas Homeowners
Africanized bees frequently nest in cavities on residential properties. Common nesting sites include:
- Tree hollows and stumps
- Wall cavities and attic voids
- Old tyres, empty containers, and equipment
- Utility boxes and meter housings
- Overturned flowerpots and compost bins
- Under decks, porches, and sheds
Prevention steps for homeowners:
- Seal gaps and cavities in exterior walls, eaves, and utility penetrations with caulk or hardware cloth
- Remove empty containers, old equipment, and debris that could serve as nesting sites
- Inspect property regularly — especially in spring when swarm season peaks
- If you find an established colony, do not disturb it — call a professional for live removal or extermination
Guidance for Texas Beekeepers
Texas beekeeping is completely viable despite the Africanized bee presence — but it requires additional vigilance compared to states without this risk. Here's how Texas beekeepers manage it:
Re-queen every 1–2 years with certified European queens
This is the single most important management practice. Queens from certified non-Africanized breeders maintain European genetics in the colony. Over time, without re-queening, wild Africanized drones can mate with your queens and shift colony genetics toward Africanized traits.
Inspect regularly and watch for defensiveness changes
Unusual defensiveness — bees boiling out of the hive, pursuing you more aggressively than before — is the earliest warning sign that Africanized genetics may be entering your colony. Act immediately if you notice this.
Always use full protective gear in Texas
Full suit, veil, and gloves are non-negotiable for beekeeping in South and Central Texas. Even experienced beekeepers use complete protection — the risk of Africanized genetics in any colony is too high to risk reduced protection.
Replace unusually defensive colonies immediately
Do not try to manage a colony that has become dangerously aggressive. Re-queen immediately with a certified European queen and destroy the old queen. If the colony does not respond, consult a Texas Master Beekeeper or professional apiary inspector.
Source bees locally from reputable certified breeders
Buy nucleus colonies, packages, and replacement queens only from Texas beekeepers who certify their stock as non-Africanized. The Texas Apiary Inspection Service (TAIS) maintains lists of registered beekeepers and can provide guidance on reputable local sources.

Are Africanized bees in Texas dangerous?
Yes. Africanized bees are dangerous due to their extreme defensiveness — not stronger venom. They respond to threats with far more bees, pursue much further (up to 400 metres), and stay agitated for hours. A mass attack can be fatal to healthy adults. Anyone with a bee allergy faces additional anaphylaxis risk.
Where are Africanized bees found in Texas?
Africanized bees are established throughout most of Texas south of a line from Abilene to Wichita Falls. They are most prevalent in South Texas, the Rio Grande Valley, Central Texas (Austin, San Antonio), and West Texas. Individual colonies have been found as far north as the DFW area.
How do I tell Africanized bees from regular honeybees?
You cannot reliably identify Africanized bees by appearance — they look virtually identical to European honeybees. Only laboratory DNA testing provides definitive identification. Behaviorally, Africanized colonies are far more defensive, responding faster with more bees. Treat any unusually aggressive wild colony in South or Central Texas as potentially Africanized.
What should I do if I'm attacked by Africanized bees?
Run immediately to enclosed shelter — a building or vehicle. Cover your face, run in a straight line, do NOT jump into water (bees will wait at the surface). Do not stop until inside shelter. Call 911 if anyone is stung extensively or shows allergic reaction signs. Remove stingers by scraping sideways.
How can Texas beekeepers protect against Africanized bees?
Re-queen annually with certified European queens, inspect regularly for unusual defensiveness, always use full protective gear, replace defensive colonies immediately, and source bees only from certified non-Africanized Texas breeders. Thousands of Texas beekeepers successfully manage bees safely with these practices.
Can I keep bees safely in Texas despite Africanized bees?
Yes. Thousands of Texas beekeepers keep bees safely. The key is sourcing certified European queens, re-queening every 1–2 years, using full protective equipment at all times, and replacing any colony showing unusual defensiveness immediately. Texas beekeeping requires more vigilance than in states without Africanized bees, but is very manageable.
