Small reaction?
Start with the basics.
A local bite or sting needs different care from an attached tick or a whole-body allergic reaction. Use the specific guide for your situation.
General information only. Severe symptoms need emergency care.
Move away & check
Leave the insect or nest area. Check for emergency symptoms before treating a local reaction.
Clean the area
Gently wash with soap and water. Follow the specific guide for a visible stinger or attached tick.
Cool & protect
For a mild local reaction, try a cold pack wrapped in a cloth. Avoid scratching or breaking the skin.
Watch for changes
Keep an eye on worsening pain, increasing redness, swelling, or signs of infection.

Know the signs that matter.
Check whole-body symptoms first. A small skin mark does not tell the whole story.
Call 911 now
Trouble breathing, swelling of the tongue or throat, fainting, or collapse can signal a severe allergic reaction. Do not wait to see if it improves.
If you have prescribed emergency epinephrine, use it as directed while getting emergency help.
Contact a healthcare professional
Increasing redness, warmth, drainage, fever, or worsening pain can need medical assessment. After a tick bite, a new rash or fever also deserves attention.
Tell your clinician when and where the exposure happened and how your symptoms have changed.
Safety references: AAAAI: anaphylaxis · CDC: after a tick bite.
Enjoy the outdoors. Plan for the pests.
A few practical habits can reduce exposure at home, on the trail, and during travel.
Before you head outside
Use an EPA-registered repellent as labeled. Cover exposed skin when practical and avoid disturbing nests.
After outdoor time
Check for ticks after grassy or wooded exposure. Remove an attached tick promptly using appropriate guidance.
Around your home
Repair window and door screens. Regularly empty and clean containers that collect standing water.
Prevention references: EPA: repellent safety · CDC: mosquito prevention.

A little clarity
goes a long way.
Quick answers to the questions readers ask first.
Can a photo tell me what bit me?
A photo may help document a reaction, but appearance alone cannot reliably identify its cause. Timing, exposure, symptoms, and an examination can matter. Start with our bite and sting clue guide.
What can I do for a mild bite or sting?
Move away from the source, gently wash the area, and use a wrapped cold pack for a local reaction. Avoid scratching. A visible stinger or attached tick needs specific care. Read our first-aid guide.
When should I call 911 after a sting?
Call 911 for trouble breathing, tongue or throat swelling, fainting, collapse, or a rapidly worsening severe reaction. Use prescribed emergency epinephrine as directed. Do not delay emergency help to read a guide.
What should I do if a tick is attached?
Remove it promptly. Use clean, fine-tipped tweezers to grip it close to the skin, then pull steadily without twisting. Clean the area and your hands. Contact a clinician if a rash or fever develops afterward. See the tick-bite guide.
Is every StingHelp guide medically reviewed?
Medical review is article-specific. A reviewer profile does not mean every guide has completed clinical review. Look for a named reviewer and documented review date on the article. Read our Medical Review Policy.
Health information should be clear about its limits.
StingHelp is an educational resource for a U.S. audience. It does not diagnose a bite or replace care from a qualified healthcare professional.
