The Cache MAD uses an Integrated Pest Management Program to control mosquitoes. This program is reviewed before, during, and after each season not only by the trustees and the Bear River Health Department but also by toxicologists, pest management specialists, veterinary pathologists, and pesticide specialists to ensure the District gets the maximum benefit for mosquito control with the least impact on health and the environment.
The District's primary method of control is the use of larvicide. Several of the compounds used target only mosquito larva and do not harm other water-based organisms, mammals, or the environment. And since the larva are usually found in high numbers in bodies of water, the "kill" rate is much more effective in this limited area.
Adulticides are used when the adult mosquito numbers are so high they present a disease risk as well as a high nuisance value. Fogging, or spraying, with Kontrol, a permethrin-based pesticide, generally occurs when the number of adult mosquitoes is high enough that people request fogging or if the presence of diseases such as WNV or WEE is confirmed. The Pesticide Discharge Management Plan (PDMP) has more information on the compounds we use to control mosquitoes.
There are many things you can do around your home to help control mosquitoes. Check out the following websites for some ideas you can use this season.
Mosquito Control for Fish or Ornamental Ponds provides helpful information on controlling mosquitoes in your water features. Please note that this links to the Alameda County Mosquito Abatement District in California; CMAD does not provide mosquito fish.
