MOSQUITO MANAGEMENT/WNV ADVISORY

Pennington County Weed & Pest mosquito adult trap counts have indicated a 
recent rise in the Culex Tarsalis mosquito population.

The Culex Tarsalis species is the most common mosquito found in South 
Dakota to carry the west nile virus vector.  With the increase in the Culex 
Tarsalis mosquito population, so does the risk of West Nile Virus 
transmission to humans.

Pennington County crews will be adulticiding between dusk and dawn on 
selected county roads when conditions are favorable for adult mosquito 
control.

Pennington County wants to remind the public of the importance of wearing 
proper clothing and insect repellent during outdoor activities particularly 
between dusk and dawn.
