The Asian tiger mosquito (Aedes albopictus) is an exotic species introduced to North America from Asia and has become a major pest and threat to public health in Maryland.From an initial discovery in Baltimore City in 1987, the tiger mosquito has extended its known range to all Maryland counties except Allegany and Garrett.
Asian tiger mosquito larvae breed in standing water that remains fairly calm and undisturbed. Larvae are common along the edges of a pond or a ditch, but they will not be found in a quick-running stream or creek. As a rule of thumb, any water that stands for at least seven days can breed mosquitoes.
The Asian tiger mosquito, an invasive species, was first found in the continental U.S. in August, 1985, in Harris County, Texas, in significant numbers. Two researchers published an article about the discovery in the Journal of the American Mosquito Control Association.  The next year, more tiger mosquitoes turned up around a pile of used.
