Mosquito Life Cycle | US EPA: What’s their lifespan? Pest Survival Guide, explaining the lifecycle of the Mosquito. Our goal in spraying mosquitos is actually in the interest of public health by interrupting the life cycle of the mosquito, we can slow or prevent mosquito born illnesses spread to people by mosquitoes to include Zika virus, West Nile virus, Chikungunya virus, dengue, and malaria (Mosquito-Borne Diseases | NIOSH | CDC).
When the mosquitos become active here in Custer County, we will start our mitigation activities, which will include our use of fogger trucks within the mosquito district. The Custer County Mosquito District trucks use Fyfanon ULV made by Cheminova (EPA Reg No. 67760-34), which has an active ingredient of Malathion. The EPA completed exceptional research in safety and recommendations for use of Malathion for mosquito mitigation (Malathion | US EPA).
The Custer County Mosquito District anticipates spraying after sundown on Tuesday and Thursday, weather permitting. This cycle of application should be sufficient in interrupting the mosquito life-cycle in the given week without a gap in coverage. Spraying after the sun goes down helps in limiting pollinators and others from exposure to these chemicals while also catching the mosquitos while they are at their most active.
There are options individuals can do within the community to help in Mosquito Abatement (What Mosquito Control Programs Do | Mosquitoes | CDC).
