Longer if you itch: Them. Itching will go away within days if you don't scratch.

A few days usually: Occasionally, people will have a delayed-type hypersensitivity reaction to mosquito bites. I am one of those people. The initial redness (relatively mild) lasts a day or two, followed by persistent redness and itching that goes on for a week or more. Hydrocortisone cream is your friend under these circumstances.

Sometimes: Usually mosquito bites only last up to a few days; however, in those people who have a delayed-type hypersensitivity reaction to them, they can last much longer. Cortisone cream usually works well. If it doesn't, i'd consider seeing the doc - high potency topical steroids might be needed. Remember, scratching can lead to infection.

Mosquito bites: Store aloe vera gel in refrigerator & apply to affected area. Rub basil leaf on bite. It repels mosquitoes & has anti-inflammatory effect. Consider applying calamine lotion or crushed ice or a cold pack. A 1 to 1 mix of water & baking soda is effective when applied to lesions. You can take oral medications like Benadryl (diphenhydramine) or Chlorpheniramine for itching.

Mosquito Bites: Mix baking soda and vinegar to make a thick paste. Apply the paste to the site of the mosquito bite. The chemistry of the paste will react with the toxins in the venom to neutralize the acid and provide immediate relief from itching.
