Preventative Measures

Given the drought, saving water is certainly a good idea (if done properly); however it becomes imperative that homeowners take the proper precautions to ensure they are not producing mosquitoes. In hot weather, mosquitoes can go from an egg to an adult in as little as 7-10 days posing health threat for diseases such as West Nile Virus.

Here are some tips that can help prevent mosquitoes if you are saving water.

  • It's always best to use a container made specifically for saving water such as a rain barrel (rather than buckets, garbage cans or other home made containers). It is extremely important to ALWAYS use a mosquito-proof screen which is usually a fine mesh (1/16 of an inch) to seal and cover the rain barrel. If the barrel is covered, this will reduce the likelihood of mosquitoes becoming a problem.
  • Keep the rain barrel lid and connectors sealed.
  • Ensure that the water you save is free of organic material such as leaves and other debris.
  • Be sure to always remove the water that pools at the top of the barrel at least once or twice a week.
  • If possible, place your barrel on a surface that will soak up any water that overflows.
  • Always inspect your rain barrel system, check for cracks or leaks. Be sure that all fittings and seals are intact and that no water accumulates on the ground around the barrel.
  • Clean the barrel, drain it and clean it at least a couple of times a year.
  • If the barrel is holding a lot of water, get free mosquitofish. Each one can eat at least 300 mosquito larvae per day. Residents can request mosquitofish online at www.FIGHTtheBITE.net
  • Lastly, if needed, consider using a larvicide product which kills mosquito larvae, a variety of products are available on the shelves of garden centers.
