I disagree !
Last month there was confirmed 3 year observation of the Zika carrying mosquito Aedes aegypti breeding in a bird bath three blocks from the White House.
Furthermore , Aedes aegypti have been found and observed breeding in Connecticut . Culex quinquefasciatus

The GLobe and Mail found on July21/16 :
"Zika was found in Culex quinquefasciatus in the northeastern city of Recife, ground zero for the outbreak of fetal brain defects caused by the virus – and this species is 20 times more common there than Aedes aegypti, which until now has been identified as the main vector.
“It’s very bad news for Brazil,” said Constancia Ayres, the entomologist who conducted the research and who has been a lonely voice
insisting that it was risky to focus exclusively on Aedes aegypti as Brazil scrambled to respond to the Zika outbreak over the last year."
“We ( Brazil) have a national program for controlling Aedes – but we have nothing for Culex – so if Culex is an important vector then we have to start from zero.”
Well, I certainly don’t consider D.C. to be particularly northerly; it is practically deep south compared to me here at 46.5° north latitude. Connecticut is more northerly than I would have expected for a breeding population. We’ll have to see how this shakes out.
