Insect bites, stings, and practical first aid
STINGHELP
Insect bites and stings: clear information for your next step
Understand common symptoms, learn practical first aid, and recognize when medical help is needed. Start with what happened and how you feel, rather than trying to diagnose a bite from a photograph.
Emergency symptoms come first
In the United States, call 911 for trouble breathing, tongue or throat swelling, fainting, or rapidly worsening symptoms after a bite or sting. Follow a prescribed emergency allergy plan. This website is educational and is not an emergency service.
Start with these practical guides
Insect sting first aid

How to make sense of an unexplained skin mark
- Record the exposure. Note outdoor activity, recent travel, contact with pets, a witnessed sting, or an attached tick.
- Describe the symptoms. Record pain, itching, swelling, warmth, and symptoms elsewhere in the body.
- Watch the direction of change. A worsening reaction deserves a different response from a mild one that is settling.
Different bites, skin irritation, allergy, and infection can look similar. Images are useful context, but they cannot confirm a diagnosis by themselves.
