Mosquito bites typically last a few days, with itching and redness peaking within 24 to 48 hours after the bite. The bump and itchiness usually fade over the course of three to four days, although swelling can sometimes last up to seven days

. Most bites heal on their own without treatment within this timeframe

. The duration can vary depending on individual reactions and how much the bite is scratched. Scratching can prolong healing, increase irritation, and raise the risk of infection, which may cause the bite to last longer or worsen

. In some cases, severe reactions like Skeeter syndrome can cause symptoms to last from three to ten days, especially in children or people with weakened immune systems

. In summary:

• Itching and redness peak in 1-2 days
• Most bites heal within 3-4 days
• Swelling may last up to 7 days
• Scratching can extend healing time and risk infection

Avoid scratching and use soothing treatments like lotions or cold compresses to help reduce symptoms and speed recovery
