Mosquito Abatement

The Vector-Borne Disease Prevention Program recognizes the importance of minimizing the impacts of biting mosquitos throughout the community.  Mosquito activity can significantly impact the quality of life of our residents and impair local businesses.  One of the program`s primary goals is to stop mosquitos while they are still in the larval stage, before they reach adulthood and are capable of biting our citizens.  

The Program utilizes an integrated approach for mosquito abatement:

  • Effective mosquito control begins with proper design and construction planning of our community landscape and infrastructure. 
  • Existing infrastructure can be modified or improved through source reduction
  • Mosquito fish control mosquitos biologically and reduce the need for mosquito control products.
  • Biological larvicide products are applied to storm water infrastructure to control mosquitos before they reach adulthood.
  • Occasionally, adulticide products are applied to control aggressive mosquitos or mosquitos carrying West Nile Virus.

Mosquito Surveillance and Treatments 

Mosquito Fish

Mosquito fish, Gambusia affinis, are able to eat large quantities of mosquito larvae. The Vector-Borne Disease Prevention Program employs mosquito fish as an effective biological method in controlling mosquitos. Our staff will stock mosquito fish in ornamental ponds, detention basins, and slow-moving streams and wetlands.

The following are some of the factors that should be considered before stocking mosquito fish:

  • Is the location a permanent water source?
  • Does the location produce mosquitos?
  • Do koi or other ornamental fish already exist in the location being considered? (Mosquito fish may be detrimental to such species.)
  • Are predatory fish species such as blue gills present? (Predatory fish will out-compete mosquito fish.)
  • Is the water quality adequate?
  • Does the depth and vegetation provide adequate harborage for the fish?

The Vector-Borne Disease Prevention Program staff is available to assist you determining if your pond is appropriate for stocking mosquito fish. You may call the office at 785-4599 for more information or to request fish for your pond.
