HI, thanks for using healthcare magic The reaction to insect bites can vary from one person to the next. In some cases, it can be severe. You would first need to consider reducing the bites by checking your environment for collections of water and using mosquito repellents as often as needed (reapply as often as allowed). If bitten, then apply a topical antihistamine to the area or take a oral antihistamine. This would reduce the inflammatory response and your desire to scratch the area. When you scratch, infection can occur. If infection occurs then use a topical antibiotic. I hope this helps
