- To protect yourself from mosquitoes use mosquito repellent and wear protective clothing. Use repellents containing DEET, Picaridin or Oil of Lemon Eucalyptus and follow the directions on the label. Never use DEET on infants. Oil of Lemon Eucalyptus should not be used on children under three. Although uncomfortable during hot days, long-sleeve shirts and long pants can provide a layer of protection.
