Some mosquitoes can carry West Nile Virus (WNV). Mosquitoes only need two tablespoons of water to breed, and water can collect just about anywhere. Each year, the City of Mansfield implements its Mosquito Surveillance Testing Program. The main goal of mosquito control is to decrease the number of adult mosquitoes by eliminating breeding grounds wherever possible. Partner with the City to prevent WNV and protect yourself from mosquitoes by staying informed and getting involved in eliminating breeding sites. 

The City is currently at risk level 1

Mosquito Risk 1 - Normal risk

Risk Level 1 - Normal Response

  • Condition: Probability of human outbreak is remote.
  • Trigger: Normal mosquito activity with no evidence of virus/disease detected during the past 6 weeks in vectors, humans, or other hosts

The best control methods for Level 1 are promoting  source reduction and personal protection. Conduct standard larviciding approaches. No adulticide spraying will occur at this response level.

Risk Level 2 - Enhanced Response

  • Condition: Low to moderate probability of human outbreak.
  • Trigger: Normal mosquito activity with little or no evidence of virus/disease; trapped mosquitoes test positive for West Nile and indicate that exposure likely occurred locally; enhanced response level is due to the recent historical presence of West Nile in vectors, humans, or other hosts within the vicinity of Mansfield (approximately 10 miles).

Risk Level 3 - Public Health Warning

  • Condition: Moderate to high probability of human outbreak.
  • Trigger: Multiple mosquito pools collected at different times and locations test positive for West Nile. Probable human or equine cases reported by laboratory testing.

Risk Level 4 - Public Health Alert

  • Condition: Multiple human cases are confirmed.
  • Trigger: Multiple human cases confirmed by laboratory testing and continued viral mosquito activity.
