Recognizing what bit you changes what you should do next.
Mosquito: single raised welt, intense itching, appears within minutes.
Ant: central white pustule with redness, may burn for several days. Tick: concentric reddish circle that expands—if this ring pattern appears, consult a doctor even if it doesn’t hurt.
Bed bug: group of welts in a line or cluster, usually in areas covered by clothing.
Scorpion: visible entry point, immediate intense pain, numbness around it—go to the nearest health center or IMSS (Mexican Social Security Institute); antivenom is free in Mexico.
Bee: welt with a central white dot; the stinger may remain embedded—remove it by scraping with a card; do not pinch.
Flea: multiple small, scattered welts, especially on ankles and legs.
Spider: central depressed area with redness; observe if it increases in the following hours. Wasp sting: raised welt without a stinger, pain more intense than a bee sting.
If you experience difficulty breathing, facial swelling, or dizziness after any sting, go to the emergency room.
