Why Do Bees Sting People if it Kills Them?

Self-Defense

Bees sting when they feel threatened. This could happen if you swat at them, try to catch them, or accidentally step on them. The sting is a bee's last resort to protect itself from perceived danger.

Hive Defense

Bees are highly protective of their hive, which houses their queen, brood, and food stores. If they sense a threat to their hive, they will sting to defend it. This is why it is crucial to avoid disturbing beehives.

Alarm Pheromones

When a bee stings, it releases a pheromone that signals other bees to come to its aid. This alarm pheromone can quickly mobilize the colony, which can lead to multiple stings if the threat is not removed.

Honeybee

About half an inch long with slender, furry bodies featuring pale yellow or tan stripes. They live in hives in hollow trees, on branches, or in man-made bee boxes. Honeybees die after stinging due to their barbed stingers.

Bumblebee

Large, oval-shaped, furry insects with black bodies and yellow stripes (0.5 to 1 inch). They typically nest in the ground and do not die after stinging because they have smooth stingers.

Carpenter Bee

Larger flying insects (0.75 to 1 inch) with shiny black bodies and yellow hairs on their thorax. They nest in wood. Only females can sting, and males are unable to sting at all.

Sweat Bee

Small, often metallic-colored bees (0.12 to 0.5 inches) attracted to human sweat. Generally not aggressive but can sting if provoked.

Africanized Honeybee

Also known as "killer bees." Similar to regular honeybees but far more aggressive and likely to swarm unprovoked. They sting in large numbers and can be very dangerous.

Honeybees Die

When a honeybee stings, the barbed stinger becomes lodged in skin. As the bee pulls away, the stinger and venom sac are ripped from its body. This fatal injury leads to the bee's death. The detached stinger continues to inject venom for up to ten minutes.

Other Bees Survive

Most other bee species do not die after stinging. Bumblebee stingers are smooth, which allows them to sting multiple times without losing their stinger or sustaining fatal injuries.

Proximity to Hives

Being close to hives in gardens, parks, or near flowering trees significantly increases sting likelihood.

Bright Clothing

Wearing bright colors and floral patterns can attract bees, as they may mistake you for a flower.

Strong Scents

Perfumes, scented lotions, and hair products can attract bees and increase sting risk.

Open Food & Drinks

Bees are attracted to sugary foods and drinks, so consuming these outdoors can draw bees closer.

Outdoor Activities

Gardening, hiking, or playing sports can expose you to areas where bees are active.

Disturbing Hives

Attempting to remove or destroy a beehive can provoke bees and lead to multiple stings.

Common Symptoms

• Burning pain that radiates from the sting site
• Redness and swelling around the area
• Itchy skin surrounding the sting
• Skin discoloration at the sting location

Pain-Causing Agents in Venom

• Melittin: Binds to red blood cells, causes hemoglobin release
• A-Hyaluronidase: Breaks down cells, helps venom spread
• Phospholipase-A: Disrupts biochemical reactions, causes cell breakdown

Epinephrine Autoinjector

Individuals with known bee sting allergies should carry an EpiPen, which provides a life-saving injection to stimulate the heart and relax airways.

Desensitization Program

For severe allergies, a series of venom injections in gradually increasing doses can build tolerance. This takes several months but has a high success rate. Always administered by a physician.

Generally Not Dangerous

When bees swarm, they are relocating to a new home. They are less likely to sting because they are focused on finding a nesting site. Bees also gorge on honey before leaving, which makes them less capable of stinging.

What to Do

If a swarm settles in an inconvenient location, contact a local beekeeping association. Experienced beekeepers can safely relocate the swarm without harming the bees or posing a threat to people.

Stay Calm

Panicking can escalate the situation and make bees more aggressive.

Cover Your Head

Use a shirt or jacket to cover your head and face. Bees often target these areas.

Run to Safety

Move steadily in a straight line toward a building or vehicle.

Seek Shelter

Get inside a sealed environment where bees cannot follow you.

Do NOT Hide Underwater

Bees will wait for you to surface. Find enclosed shelter instead.

Do NOT Swat

Swatting releases alarm pheromones that attract more bees to attack.
