Mosquito Dunk Update
The City of Rowlett no longer has packages of Mosquito Dunks (BT Tablets) available to residents. The supply of Dunks provided by Dallas County in 2014 has been depleted. The City of Rowlett urges citizens in an effort to help in controlling mosquitoes and West Nile virus, to visit local home and garden centers to purchase these over-the-counter treatments.
The City of Rowlett will update citizens if additional Mosquito Dunks are received in 2015.

West Nile Virus Information
West Nile Virus is a disease that is spread by the bite of a mosquito. Mosquitoes become infected when they feed on the blood from infected birds. The infected mosquitoes can then transmit West Nile Virus to humans and animals.
West Nile disease can vary in severity. People 50 years of age and older have the highest risk of severe disease.
- Severe West Nile (Neuroinvasive Disease) - infections can cause neurologic complications such as encephalitis. Symptons include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. It is estimated that approximately 1 in 150 persons infected with the West Nile virus will develop a more severe form of disease.
- West Nile Fever - It is estimated that about 20% of people who become infected with WNV will develop West Nile Fever. Symptoms include fever, headache, tiredness and body aches. Occaisionally a skin rash on the trunk of the body and swollen lymph glands will occur. While the illness may last only a few days, even healthy people have reported being sick for several weeks.
Mosquito season in Dallas County runs from April to October/November with peak activity in August. Residents are encouraged to be vigilant and on heightened alert during these months.
