Check your own yard for common water sources listed on the door hanger and dump them weekly or eliminate the water sources completely when possible. These door hangers mean that the invasive Aedes aegypti mosquito has been found in your area. You do not need to contact the District at this time but, in the future, we may need to inspect your front and backyard for potential sources. Learn what mosquito sources to look for here or fill out an online service request form to request a technician’s help here.
