I disagree because the reaction to a mosquito bite is an after effect of being bitten. By the time you realize you’ve been bitten, it’s too late. Any damage is already done. It’s also difficult to see mosquitoes, as they are small. Similar to ticks, they do not usually trigger a sensation that you would feel. The best you could hope for is to recognize and correlate the itchiness with the locations you visit, and learn to stay away from that area at certain times.
