how long does it take for mosquito bites to go away

Mosquito bites usually go away in a few days, and the itch and swelling often peak within the first 24 to 48 hours before fading. Most people are mostly better within 3 to 7 days, though scratching can make them last longer or get infected.

What’s typical

  • A small bump can appear within minutes.
  • Itching often gets worst in the first 1 to 2 days.
  • Redness and swelling usually settle over the next few days.

When it lasts longer

Some bites can take up to a week to fully heal, especially if you scratch them a lot. Bigger reactions, sometimes called skeeter syndrome, can last longer and cause more swelling.

When to get help

Watch for signs of infection or a stronger reaction, such as:

  • Increasing pain, warmth, redness, or pus.
  • Fever, severe headache, or body aches.
  • Major swelling, especially around the eyes.

Quick relief

  • Use a cold compress.
  • Try an over-the-counter anti-itch cream or a non-drowsy antihistamine.
  • Avoid scratching, since that can slow healing.

TL;DR: most mosquito bites fade in about 3 to 7 days, with the worst itch usually in the first 1 to 2 days.
