Organized mosquito control agencies often go to extraordinary lengths to accommodate individuals who, for varying reasons, prefer their property not be sprayed with approved public health insecticides. When survey data indicate the need for adult sprays for reasons of protecting public health, they are approved, planned and conducted with special regard to the concerns of chemically sensitive persons in most jurisdictions. Personal notification of chemically-sensitive individuals of spray times in addition to using Global Positioning Systems (GPS)/Global Information Systems (GIS) technology to reduce the likelihood of drift over unauthorized areas are but a few of the means utilized to ensure mosquito control serves the entire public spectrum. Contact your local district if you have a concern or a request regarding mosquito control activities.
