Most people, when bitten by a mosquito will suffer from an allergic bite mosquito reaction.  Usually an itchy red bump from a mosquito bite will not occur until about 12 to 24 hours after the bite has occurred, so it is hard to tell sometimes how badly you�ve been bitten until it is too late!  The female mosquito is the only one that actually bites.  The allergic bite mosquito reaction comes from an allergy to the saliva that the mosquito injects into your skin to keep your blood from coagulating around her proboscis. 

There are several key steps you can take to avoid an allergic bite mosquito reaction.  First off, if you are going to be camping around or hiking in woods that are dense with mosquitoes, be sure to wear plenty of repellent and long pants and sleeves.  Also use netting around your tent and picnic areas to keep mosquitoes from biting.
