What Insect Stings Is, and Why It Matters
Insect Stings: what it is, why it matters, and what published guidance actually asks of you.
Large local reactions are common and alarming but not dangerous; systemic reactions are the ones that matter.
Key takeaways
- Large local reaction: swelling around the site; not anaphylaxis
- Systemic reaction: symptoms away from the sting site
- Most useful single change: Scrape a bee sting out sideways rather than pinching it.
- Commonest mistake: Squeezing a sting, which injects more venom.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The short answer
Reactions to bee, wasp and other insect stings, from local swelling to anaphylaxis.
Where it fits
This is part of Allergies. The rest of this page works through the figures and then the practical side.
The numbers, in one place
| Measure | Figure |
|---|---|
| Large local reaction | swelling around the site; not anaphylaxis |
| Systemic reaction | symptoms away from the sting site |
| Bee stings | remove the sting by scraping, not squeezing |
| Venom immunotherapy | available for people with systemic reactions |
What that means in practice
Translated into things you can actually do:
- Scrape a bee sting out sideways rather than pinching it
- Apply a cold compress and take an antihistamine for local swelling
- Seek referral for venom immunotherapy after any systemic reaction
- Carry prescribed adrenaline auto-injectors if you have had one
What gets people into trouble
Where people most often come unstuck:
- Squeezing a sting, which injects more venom
- Assuming a large local swelling means the next sting will be dangerous
- Ignoring symptoms occurring away from the sting site

When to speak to a doctor
Call 999 for swelling of the lips, tongue or throat, difficulty breathing, wheeze, widespread rash, dizziness or collapse after a sting, and use an adrenaline auto-injector immediately if prescribed. Stings inside the mouth or throat need urgent assessment regardless of allergy, because swelling can obstruct the airway.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
