Abatement and operations
The Clark County mosquito crew conducts surveillance and abatement activities through the active mosquito season, usually April 1 through October 1, each year. The priority is to attack mosquitoes at their source, by treating mosquito larvae as they hatch. It is far more effective to reduce mosquito populations at their source, before they fly into neighborhoods, than to fog large, open areas in attempt to eliminate adult mosquitoes. It is very difficult to reduce mosquito populations once they have spread from the breeding source.
Control measures used by the crew comply with policies adopted by the Board of Trustees of the Mosquito Control District and with state and Environmental Protection Agency regulations. Biological control methods are used that have the least adverse effect on humans, pets, wildlife, and the environment.
The crew implements an Integrated Pest Management (IPM) program and uses a variety of products and equipment to control mosquitoes. Treatment methods in Clark County include larvicide applied by helicopters, broadcast from trucks, all-terrain vehicles, amphibious vehicles, and on foot from backpack applicators. Larvicide briquettes are placed into storm drains and catch basins. Limited treatment is applied to adult mosquitoes due to the limited effectiveness of this method and the short duration of the materials. Due to legal restrictions, the Mosquito Control District cannot spray or fog neighborhoods or private residences.
The Clark County mosquito control crew works April 1 through October 1 each year. During that time requests for service or information regarding mosquito control can be made through either the 24-hour service request line at 360.574.7906 or on-line service request.
