Cache Mosquito Abatement District (CMAD)
2011 Season Summary
There were no cases of WNV--human, horse, or bird--confirmed in the district this year. No mosquito pools tested positive for WNV. The district began checking for mosquito larvae in early May and found them in high quantities throughout the area. Abatement efforts to kill the larva were intensified; larvaciding targets the larvae and is more efficient than fogging by killing large numbers of mosquitoes before they mature and can fly to other breeding sites. Fogging is done to control the adult mosquitoes and is subject to weather and wind conditions. The annual report may be found here.
In October, the long-term contract with Bear River Health Department to provide abatement and surveillance was ended. CMAD personnel and trustees have been learning how to run a mosquito abatement program from BRHD since our start in 2005. We will have a Field Operations Manager hired by the end of February and be ready to provide the same high level of abatement services by the start of the 2012 mosquito season.
