Unlike most indigenous species, Asian tiger mosquitoes bite aggressively and can survive the colder temperatures in northern climates. Since 1985, Asian tiger mosquitoes have spread to 37 states, including New Jersey, Pennsylvania and New York. In fact, Asian tiger mosquitoes are the only mosquito species in the New York area that can transmit the Zika virus as well as over 20 other diseases, including West Nile fever, dengue fever, yellow fever and two types of encephalitis. Asian tiger mosquitoes can also transmit the chikungunya virus that, while rarely fatal, causes joint pain, fever, overall aches and pains, as well as headaches, nausea, vomiting, rashes and fatigue.
