Mosquito Control

Mosquito Control Program

With summer heat comes mosquito season and a concern about the threat of the mosquito-borne West Nile Virus. The City of Vermillion has adopted an environmentally friendly and non-toxic mosquito control program to improve drainage and apply larvicide to standing water on city property. This simple strategy eliminates mosquito breeding grounds on city property and depends on the active partnership among the various city departments and area citizens.

The City of Vermillion will post a press release 24 hours prior to fogging the city. If you would like to be added to the no fog list prior to fogging please call 605-677-7050.

Precautions on Private Property

Citizens are responsible for undertaking mosquito control measures on private property. Mosquitoes that are most likely to carry the West Nile Virus do not breed in fresh or flowing water; therefore, the city recommends that property owners eliminate standing water by:

  • Remove all discarded tires on your property. Used tires have become an important source of mosquito breeding in the nation.
  • Drill holes in the bottoms of recycling containers that are kept outdoors.
  • Make sure roof gutters drain properly, and clean clogged gutters in the spring and fall.
  • Turn over plastic wading pools and wheelbarrows when not in use.
  • Change the water in birdbaths.
  • Clean vegetation and debris from edges of ponds.
  • Clean and chlorinate swimming pools, outdoor saunas and hot tubs.
  • Drain water from pool covers.
  • Use landscaping to eliminate standing water that collects on your property.

Precautions Outdoor

The City of Vermillion recommends that individuals use mosquito repellent containing deet, Picaridin or oil of lemon eucalyptus, according to directions, when outdoors. Limit outdoor activities at dawn and dusk, when mosquitoes are most active.
