We trap mosquitos for several reasons.  The primary reasons are for disease testing and to determine the number of mosquitos in an area.   Understanding what species of mosquitoes are prevalent in an area helps us to determine what kind of treatment is necessary.

Adult mosquito surveillance is a critical component of determining where mosquitoes are coming from, the potential for disease transmission in an area, and the need for adult mosquito control. This district uses adult surveillance as a quality control mechanism to determine how effective the overall program is in reducing mosquito populations. Collecting baseline data on mosquito populations and mosquito-borne disease also helps target educational efforts.
