Hi my son is 2.7 years, he scratches his legs after mosquito bite and it leaves marks, I don't see any mosquito in our house. What should I do to remove wound marks. Wounds are not regularly comming

A. it is important to prevent mosquito bite by using other mosquito nets and the second option would be mosquito repellent vaporizer. therez are also available cloth roll on. you can apply mosquito repellent cream on the skin if it is not causing any allergy. make the czhild wear full clothes to decrease the chances of bite and if a bite occurs you can apply coconut oil to decrease the sensation
