The Asian tiger mosquito is an exotic species that gets its “tiger” name from the single white stripe down the center of its head and back. This biting insect can transmit harmful diseases like West Nile virus, Chikungunya and dengue fever.
Like other mosquito species, only females require a blood meal to produce eggs. Asian tiger mosquitoes typically feed during the daylight hours when they are most active. The males do not bite and primarily feed on plant nectar.
The bite from a female Asian tiger mosquito can leave an itchy, red bump on the skin. But, the real threat posed by this pest is its ability to transmit numerous diseases including West Nile virus, encephalitis and dengue fever. The Asian tiger mosquito is also the primary vector for Chikungunya, a virus similar to dengue fever. The disease originated in southeast Africa and was first described in Tanzania in 1952. It has since spread throughout the Americas, the Caribbean islands, and most recently in the United States.
In warm regions, Asian tiger mosquitoes are active year-round. However, they are known to overwinter in temperate climates. The females lay their eggs inside items that can hold stagnant water, such as tires, flowerpots, birdbaths and clogged drains.
The most effective way to prevent contact with Asian tiger mosquitoes is to eliminate areas of standing water around the home such as baby pools, flowerpots and birdbaths. Homeowners should also screen all windows and doors. Those who spend time outdoors should wear long pants and sleeves, and use an insect repellent containing 20 percent DEET.
The Asian tiger mosquito is a problem because it's an aggressive daytime biter that can transmit serious diseases like dengue, Chikungunya, Zika, West Nile virus, and yellow fever to humans. It spreads rapidly through international trade and outcompetes native mosquito species.
Get rid of Asian tiger mosquitoes by eliminating standing water where they breed. Empty containers, old tires, bird baths, and clogged gutters are cleaned weekly. Professional pest control using targeted treatments and insecticides is most effective for larger infestations.
Asian tiger mosquitoes are attracted to body heat, carbon dioxide from breath, sweat, dark clothing, and standing water in containers where they lay their eggs. They're also drawn to shaded, moist areas around homes and yards.
