Some 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.

Risk Levels

The City is currently at Risk Level 2

How to Get Rid of Mosquitoes: Eliminate Common Hangouts

Don’t give mosquitoes a place to stay by emptying standing water from these and other areas around your home and yard:

  • Open trash carts
  • Boats and pool covers
  • Fountains and bird baths
  • Clogged rain gutters
  • Low areas
  • Water bowls for pets
  • Buckets and barrels
  • Flower pots and saucers
  • Leaky hoses
  • Wagons and other toys
  • Ponds
  • Neglected pools
  • Tires
  • Piles of trash or debris

To treat stagnant water, use Bti briquettes, which is not a chemical. Each briquette will treat 100 square feet of surface water for 30 days. To apply, simply drop the briquette in standing water. Bti is available in limited supply from the City or can be purchased at local garden/hardware stores.

City Bti Distribution Locations

Residents will need to bring a valid driver's license and utility bill for proof of residence. The limit is two donuts per resident.

Protect Yourself against Mosquitoes

  • DRAIN standing water around your home, yard, and neighborhood
  • DUSK and DAWN are the times of day you should try to stay indoors; this is when mosquitoes are most active
  • DRESS in long sleeves and pants when you’re outside, and spray thin clothing with repellent
  • DEFEND yourself by using an insect repellent that contains DEET, Picaridin, or Oil of Lemon Eucalyptus     

West Nile Virus and Symptoms

West Nile virus is a potentially serious virus that affects the nervous system. According to the Centers for Disease Control, it is established as a seasonal epidemic in North America, typically from late spring through summer and fall. This mosquito flies short distances (often much less than a mile) to feed. Adult mosquitoes have a life span of a few weeks during the summer months.

Symptoms usually appear within three to 15 days of being bitten. If you are concerned about any symptoms you or a family member are experiencing, see your health care provider.

About the Mosquito Surveillance and Response Plan

The program is a partnership between the City of Denton and the University of North Texas. This surveillance program collects adult mosquitoes that are sent to the Texas Department of State Health Services for testing. The overall goal is the use data on mosquito populations and mosquito virus infections rates to:

  • Assess the threat of human disease
  • Determine the geographical areas of highest risk
  • Determine the need for intervention events, and timing events
  • Identify larval habitats that are in need of targeted control
  • Monitor the effectiveness of control measures
  • Better understand transmission cycles and potential vector species

The use of ultra-low volume aerosols (”fogging”) will only be considered if there are conditions indicative of Risk Level Five (Public Health Alert) and if other control measures appear to be ineffective. If adulticiding is implemented, citizens residing in areas where applications will occur will be notified through several methods including Robocall, CodeRED, eNews, through this website, and on the City Facebook page.
