Also question is, can insect bites appear days later?
Take a Bite Out of Mosquito Stings. A mosquito bite can cause a variety of reactions. People who have never been bitten before (primarily young children) may not react at all. Thereafter, most of us develop a tiny, itchy red bump that appears hours to days after they have been bitten and may last a few days.
Keeping this in view, how long does it take for mosquito bites to show up?
Common symptoms of mosquito bites include soft bumps on the skin that may become pink, red, and itchy. In most cases, redness and puffiness appears minutes after the mosquito punctures the skin. A firm, dark red bump often appears the next day, although these symptoms may occur up to 48 hours after the initial bite.
