Vector Control staff investigate citizen complaints dealing with mosquitoes, flies and non-native rodents. We also enforce and ensure compliance of the Maricopa County Environmental Health Code.

Vector Control inspectors identify routine breeding sites and apply the appropriate treatments. They also perform surveillance activities in their "districts" to identify new or potential breeding sites. We also work in conjunction with State officials in monitoring and testing of mosquito samples that are collected on a monthly basis and tested for arboviruses.

The Vector Control office also provides mosquito eating fish (Gambusia) free to the public, for use in ponds, stock tanks, or any permanent waters a homeowner may have. We also try to educate individuals and citizen groups on mosquito reducing techniques they can use around their home or property to eliminate mosquito breeding. We do this through the use of pamphlets, neighborhood meetings and presentations.
