Aedes aegypti can transmit diseases like Chikungunya, Dengue, Yellow Fever and Zika. The county says none of these diseases are currently found in California.
"They like to bite several times and they like to bite anytime," the county's Vector Control District manager, Dr. Nayer Zahiri told ABC7 News. "Especially day bites."Also setting apart Aedes aegypti, the county said the mosquitoes can lay eggs in spaces as small as a bottle cap and those eggs can survive for more than a year.
There aren't very many homes nearby, but there are commercial businesses. The county's Consumer and Environmental Protection Agency director Edgar Nolasco said these businesses can provide perfect conditions for the pests to thrive."A recycling center has thousands and thousands - used tires, milk cartons - all these little things that can hold bodies of water," Nolasco told ABC7 News. "That could potentially hold the eggs.
While these mosquitoes aren't native to California, they have been detected in 20 counties including Santa Cruz and Contra Costa counties.
