Culex species are the most widespread mosquito species across the world. They are known to be highly opportunistic feeding on humans and animals, a behaviour which increases their potential to transmit zoonotic diseases and makes them important threat to public health. These common house mosquitoes are the principal vectors that spread the viruses that cause West Nile fever, encephalitis and filariasis. Mostly bite between the dusk and dawn definitely at night, bite people when other animals are not nearby. The average life span is about 10 to 60 days.
