Mosquito Control

The Noblesville Street Department has been and is continuing to treat for mosquitoes by testing for mosquito larvae in neighborhood ponds that do not have fountains. If the test is positive, the Street Department treats the pond with larvicide. The larvicide is EPA-approved and is safe for fish and for animals – it only kills mosquito larvae. Mosquito larvae are unable to survive in flowing water, including neighborhood ponds with fountains.

In order to effectively control mosquitoes in yards, residents are urged to search their property to identify any items or areas that hold water and drain that water. Standing water (even a small amount) is a breeding ground for mosquitoes and often contains high concentrations of mosquito larvae. Areas that are prone to standing water include gutters, old tires, toys, and uneven areas in gardens or lawns to name just a few. Residents should also regularly change the water in bird baths, wading pools, pets' water bowls, etc.

In addition, the EPA recommends limiting your exposure to mosquitoes by taking the following steps:

  • Apply an EPA-registered insect repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol to clothes and exposed skin.
  • When possible, stay inside during early morning hours and during evening hours when mosquitoes are especially active.
  • Make sure the windows and door screens in your home are "bug tight."
  • Cover exposed skin by wearing a hat, long sleeves and long pants in places where mosquitoes are especially active, such as wooded areas.

Mosquitoes breed in standing water. Even a container as small as a bottle cap can become a breeding ground, according to officials. Residents should take these steps:

  • Discard old tires, tin cans, ceramic pots, unused plastic pools or other containers that can hold water.
  • Repair failed septic systems.
  • Drill holes in the bottom of recycling containers left outdoors.
  • Keep grass cut short and shrubbery trimmed.
  • Fill or drain puddles, swampy area and tree stumps.
  • Clean clogged roof gutters, particularly if leaves tend to plug up the drains.
  • Frequently replace the water in pet bowls.
  • Flush ornamental fountains and birdbaths periodically.
  • Aerate ornamental pools, or stock them with predatory fish.

West Nile virus can cause West Nile fever, a mild form of the illness, which can include fever, headache, body aches, swollen lymph glands or a rash. Some people will develop a more severe form of the disease affecting the nervous system, including inflammation in the brain and spinal cord, muscle paralysis or death. People who think they may have West Nile virus should see a healthcare provider.
