Recent heavy rains in North Texas has increased the flood water mosquito population and slowed the start of West Nile season. While flood water mosquitoes do not traditionally carry diseases that affected humans, it is still important to be on guard against bites by dressing in long clothing, draining any standing water and using insect repellent that contains DEET, picaradin or lemon oil of eucalyptus.

"This sudden explosion of mosquitos is a result of the recent rains which have flooded lowlying areas where Aedes vexans mosquito eggss have laid dormant for two years," said Scott Sawlis, Entomologist for Dallas County Health and Human Services (DCHHS). "And while, these mosquitos do bite and are definetly a pest they do not pose a risk of exposing humans to mosquito borne illnesses such as West Nile Virus. In North Texas the culex mosquito or southern house mosquito is the vector for West Nile virus," Sawlis continued.

"Since the average person can't distinguish between the flood water and house mosquitos, we encourage everyone to use the increase mosquito activity as a trial run for West Nile Season and to be on the defense against mosquito bites," said Zachary Thompson, DCHHS Director.
