We haven’t seen mosquitoes around in Orange County for the whole year until recently when the weather starts to cool down. In this past week, my coworkers have been complaining about mosquito bites around the ankle during the day at work, which is abnormal compared to normal mosquitoes that bite during dusk and at night. One of my poor coworkers even developed serious skin infection and had to wear ice packs around her swollen ankles.

NBC Los Angeles has confirmed that this is an invasive mosquito species called Aedes albopictus, also known as the Asian Tiger Mosquito. It landed in California first in 2001 with shipments of bamboo from China and is coming back this year. They are way more aggressive and “smart” than local Culex Mosquitoes: they prefer human blood and like to bite you below the knees so it’s hard to be noticed; and, they can breed in as little water as ⅛ inch deep of water, e.g. a bottle cap that gets hit by a sprinkler.
