That’s why on hotter days, they search shade and why they usually aren’t round when the thermometer dips under the mid-50s.

In 2012, Texas skilled its largest outbreak of West Nile virus in historical past with over 1,800 confirmed circumstances.

“Most of those victims reported they have been bitten at house,” Swiger mentioned. “So, it’s essential that Texans remember always and use repellant when vital.”

She mentioned dengue is the opposite most essential mosquito-related illness Texans want to concentrate on. While it’s primarily seen in South Texas, the Lower Rio Grande Valley and areas bordering Mexico, somebody that contracts it may journey anyplace.
