Mosquito Control Reports

Per the 2019 Annual Report, the primary objective of the City of Louisville Mosquito Control Program is to employ trained field technicians to suppress populations of larval mosquitoes in aquatic habitats.  Technicians utilize bacterial larvicides that reduce mosquitoes without harming non-target organisms.  Additionally, monitoring of adult mosquito populations is an essential component of an Integrated Mosquito Management (IMM) program.  Surveillance trapping performed provides data to assess West Nile Virus (WNV) infection rates, as well as the need for adult mosquito control measures.  Data driven response can reduce the threat of disease transmission and annoyance associated with mosquitoes, while reducing the necessity for large amounts of products to be applied.

Information on all things mosquitos, West Nile Virus and personal protection can be found at the following websites:

Boulder County Public Health and City of Louisville urge residents to remember the 4D's when protecting themselves against mosquitos and WNV:

  1. Drain - remove standing water from your property
  2. Dress - wear long pants and sleeves to prevent mosquito bites
  3. Dawn and Dusk - avoid being out side during peak mosquito activity
  4. Defend - wear EPA approved repellents including DEET, Picaridin and Oil of Lemon Eucalyptus
