Mosquito Safety

Mosquito Risk Level 2Some mosquitoes 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 Denton implements its Mosquito Surveillance and Response Plan. 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.

The City is currently at Risk Level 2.

Risk Level 2 - Enhanced Response

  • Condition: Probability of human outbreak is low.
  • Trigger: Normal mosquito activity with little or no evidence of arthropod-borne virus/disease. Enhanced response level is due to recent historical presence of arthropod-borne virus/disease in vectors, humans, or other hosts within the vicinity of Denton (approximately 100 miles).

Risk Level 2 is enacted typically before the mosquito season is underway and information centers on activities citizens can do to help the City control the mosquito population. At this Risk Level, the probability of human outbreak of the West Nile virus is low. Strategies for protecting human health and methods for minimizing mosquito populations are the main control measures emphasized under Risk Level 2.

Risk Level 3 - Public Health Concern

  • Condition: Probability of human outbreak is low to moderate.
  • Trigger: Arthropod-borne virus/disease isolated from mosquitoes collected during trapping activities at a single monitoring site.

Risk Level 4 - Public Health Warning

  • Condition: Probability of human outbreak is moderate to high.
  • Trigger: Multiple mosquito pools collected at different times and locations test positive for arthropod-borne virus/ diseases. Single human case confirmed with laboratory testing.

Risk Level 5 - Public Health Alert

  • Condition: Human outbreak is confirmed.
  • Trigger: Multiple human cases.
