How do mosquito control districts control mosquitoes?


How do mosquito control districts control mosquitoes?  Integrated mosquito management methods currently employed by organized control districts are endorsed by the CDC and EPA.  They employ comprehensive and specifically tailored control methods for each stage of the mosquito life cycle.  Larval control through water management and source reduction is a prudent pest management practice, as is the use of the environmentally friendly EPA approved larvicides.  When source elimination and larval control measures are unattainable or in the case of imminent disease, the EPA and CDC have emphasized in a published joint statement the need for considered application of adulticides.  A successful mosquito management program includes the following elements:

  • Larval and adult mosquito sampling (surveillance and trapping),

  • Source reduction,

  • Larviciding and adulticiding when indicated by surveillance,

  • Resistance monitoring,

  • Disease surveillance in mosquitoes,

  • And public education.
