Northwest Dallas with its warm climate, frequent spring and summer storms, and mix of urban, suburban, and creek-side environments supports several mosquito species throughout much of the year. Some are aggressive daytime biters, others become active at dusk, and a few are capable of spreading mosquito-borne illnesses such as West Nile virus.
