Two invasive Aedes aegypti mosquitoes were recently caught in San Jose, marking the first time the "aggressive" species has been seen in Santa Clara County, officials said Monday.

The department uses hand-to-hand decks to eliminate blood-sucking insects that can be carriers of various diseases, including dengue, chikungunya, Zika, and yellow fever, although they have not transmitted any viruses. never wore it aired in California, according to a state press release. The California Department of Health is testing both mosquitoes for infection. Although A. aegypti will not fly far from where they hatch, at less than 500 feet high, they are aggressive, bite at any time of day, and prefer humans to animals.

"We take this threat seriously and are doing everything possible to prevent A. aegypti from colonizing Santa Clara County," Edgar Nolasco, director of the county's Consumer and Environmental Protection Agency, said in a statement. "We are asking the public to help by removing standing water from their property and encouraging residents to protect themselves from mosquito bites."

The species, which likely originated in sub-Saharan Africa and is now found in many tropical and subtropical climates, has been reported in at least 20 California counties, according to the state Department of Public Health.

"We know they will eventually find the bay due to global warming and their tendency to spawn in containers," Nolasco wrote in an email to SFGATE. "The district has implemented a strategic plan, anticipating the invasion of invasive mosquitoes in our country."

Plants like bamboo and bromeliads, as well as everyday items like car tires, can help move populations across borders, according to Nolasco. "They can also follow people in their cars, so travelers can take them with them," he wrote.

Since the black-and-white striped mosquito has been spotted near the intersection of Dixon Landing Road and McCarthy Boulevard in San Jose, the county is monitoring the situation closely, trapping adults and releasing their eggs.

To prevent the population from growing, officials are asking Santa Clara County residents to remove even the smallest containers from standing water, such as buckets, pet plates, and bird trays. After the mosquito lays its eggs in this container, it can survive without water for a year.

"Mosquito and vector control is a joint effort," Nolasco wrote to SFGATE. "Once these mosquitoes breed, it is very difficult to get rid of them."

Santa Clara County residents who experience a mosquito bite during the day should immediately report it to the Vector Control District at (408) 918-4770 or vectorinfo@cep.sccgov.org .
