We hate mosquitos for several reasons. First, mosquitos carry viruses and disease such as Malaria and Japanese encephalitis, so the viruses can be transmitted to people when the mosquitos suck people’s blood. Second, mosquitos make annoying sounds. For example, they make annoying sounds at near of our ears when we sleep. Third, After they bite us, we feel itchy seriously. Finally, we have to spend money because of mosquitos. For instance, we have to spend money to buy medicines, mosquito sprays and mat.
