TL;DR: Not all bees and wasps sting. Many females can sting, while males cannot. Worker honey bees have barbed stingers that can remain in the skin, while female bumble bees and many wasps can withdraw theirs and sting again.

Do all bees sting? 

No. Not all bees can sting.

Among the bees people commonly encounter, females such as worker honey bees, bumble bees and carpenter bees can sting. But stinging is primarily defensive. A bee gathering pollen or nectar away from its nest usually has little reason to confront a person.

Do all bees have stingers?

No. Male bees do not have stingers, and some female bee species lack a functional stinger.

The stinger is tied to female reproductive anatomy, which is why only females can have one. Among common bees, female honey bees, bumble bees, carpenter bees and many solitary bees have functional stingers; stingless bees are the notable exception.

Which bees sting?

Among the bees people commonly encounter, females are the ones capable of stinging.

Note: Bees that cannot sting include honey bee drones, male carpenter bees and stingless bees.

Do all wasps sting?

No. Being capable of stinging does not mean every wasp is equally likely to do so.

Social wasps, including yellow jackets, paper wasps and hornets, defend a shared colony and may sting when the nest is threatened. Solitary wasps, such as mud daubers and cicada killers, do not defend large colonies and are generally less likely to sting people. Many solitary wasps use their stingers primarily to paralyze prey for their young.

Do all wasps have stingers?

No. Male wasps do not have stingers.

Among common wasps, female yellow jackets, paper wasps, hornets, mud daubers and cicada killers have functional stingers. In some parasitoid wasps, however, the ovipositor is used primarily for laying eggs rather than for stinging people.

Which bees leave their stinger behind?

Worker honey bees are the bees most likely to leave a stinger behind. Their stingers have backward-facing barbs that can catch in the skin. When the bee pulls away, the stinger may remain lodged and tear away from the bee, which usually kills it.

Can you be stung without a stinger being left behind?

Yes. Bumble bees, most wasps and many other bees can withdraw their stingers, so a sting does not always leave anything behind.

When do bees and wasps sting?

Bees and wasps are most likely to sting when they are physically threatened or when a nest is disturbed.

Common situations include:

• Stepping on a bee
• Trapping an insect against skin or clothing 
• Swatting or grabbing at it
• Mowing or trimming near a hidden nest
• Reaching into or blocking an active nest entrance
• Handing objects close to a nest

The key distinction is proximity. A bee visiting flowers or a wasp searching for food usually has little to defend. Near a nest, however, social bees and wasps are protecting the colony, which makes defensive stinging more likely.

Note: Yellow jackets can be especially noticeable in late summer and early fall, when colonies are larger and some natural food sources become less abundant. More workers may then forage around outdoor food, sweet drinks, ripe or fallen fruit and trash.

What should you do around a nest or heavy activity?

First, determine whether you are seeing ordinary foraging or repeated traffic to a nest.

A few insects visiting flowers or food usually call for space and removal of attractants. Repeated flight in and out of the same hole, wall opening, eave or ground opening is a stronger sign of a nest and deserves more caution.

• Do not block an active nest entrance. Returning workers may gather around the area.
• Avoid mowing or trimming near suspected ground nests. Vibration and close disturbance can trigger defensive behavior.
• Cover food and drink outdoors. This reduces foraging around people.
• Secure garbage and clean sweet spills. Fewer food cues mean fewer repeat visits.
• Watch flight paths from a distance. Repeated movement can help reveal a nest entrance safely.
• Pay closer attention to nests near doors, walkways and play areas. Location determines how often people are likely to come too close.

If a yellowjacket, hornet or paper wasp nest does need treatment, Final Hex is designed for direct nest application from up to 15 feet away. Apply before sunrise or after sunset and follow the label directions carefully.

Note: Not every bee or wasp nest needs to be removed. Many species provide pollination and insect-control benefits, especially when the nest is away from high-traffic areas.

When should you worry about a bee or wasp sting?

Most bee and wasp stings cause pain, redness, itching or swelling around the sting site.

Seek emergency medical help if symptoms include:

• Trouble breathing or swallowing 
• Swelling of the lips, tongue, face or throat
• Widespread hives
• Dizziness or fainting

Prompt medical guidance is also important after many stings, a sting inside the mouth or throat, or if the person has a history of severe allergic reactions.
