West Nile Virus Awareness and Prevention Prevention - Standing WaterMosquitoes develop in large and small pools of standing waters, and not in flowing water. Be mindful of standing water in rain barrels, ornamental ponds, troughs, dugouts, creeks or sloughs. To prevent them from becoming mosquito development sites:
Remember, not all standing water produces mosquitoes. Large, deeper wetlands with open water are not good habitats. Sunlit, shallow (less than 60 centimetres, or two feet deep) water with plants growing at the edge are of most concern. LarvicideIf you cannot eliminate standing water around your home or yard, you can apply a biological control agent called larvicide. The most common is Bacilus thuringiensis israelensis or Bti (Aquabac® or Vectobac®):
You may hear of alternate methods to control mosquito larvae, including adding cooking oil or dish detergent to the water. It is unclear how effective or safe these methods are. Saskatchewan Health recommends that you eliminate standing water or make standing water more safe through the methods mentioned on this website. |
