NORFOLK, Va. (WVEC) -- Orkin just released its Top 50 Mosquito Cities List and Norfolk/Portsmouth/Newport News ranked 14th.

The list is based on the number of mosquito customers serviced in 2015.

As temperatures increase, so will the threat of mosquito-borne illnesses like Zika virus. While June, July and August are the prime months for mosquito activity, mosquito season can begin as early as March in the southern part of the United States where temperatures are warmer.

“Mosquitoes are a major health concern during the summer,” said Ron Harrison, Ph.D., entomologist and Orkin technical services director. “Mosquitoes are known carriers of several diseases, including Zika virus, Chikungunya virus and West Nile virus, so people across the United States – whether their city is on the list or not – need to take precaution to help prevent mosquito bites,” Harrison added.

The Atlanta area tops Orkin’s list of Top Mosquito Cities for the third year in a row, followed by Chicago and Washington, D.C. Mosquitoes affect people in every state in the U.S.
