Yellow Fever Mosquito Detected in Chino Hills

Aedes aegypti, commonly known as the yellow fever mosquito, has been detected in Chino Hills, according to the West Valley Mosquito and Vector Control District, a public health agency managing the outbreak. Enhanced surveillance was triggered on August 21st as a response to a resident’s complaint of daytime biting mosquitoes, and traps were placed near Slate Drive and Agate Road in Chino Hills.

Yellow fever mosquitoes are small mosquitoes with white bands on their legs, says a press release by the West Valley Mosquito and Vector Control District. “[Aedes] prefer to lay eggs in man-made receptacles such as tires, fountains, potted plants, and birdbaths.” Their eggs are laid “on the sides of containers, usually just above the water line, and can withstand drying and heat for up to 12 months. When the eggs meet with water, they activate and hatch.”

Yellow fever mosquitos are a known transmitter of numerous diseases including: the West Nile virus, dengue, and Zika virus. The mosquitos have “unique biting and egg laying habits” that give the mosquitoes the potential to “spread rapidly and introduce previously unseen human disease to our area.”

Brian Reisinger, a spokesman for the West Valley Mosquito and Vector Control District, says that they are currently conducting trapping and testing operations to determine the extent and severity of the infestation. The agency will be testing captured mosquitoes for West Nile Virus and other vector-borne diseases.

In order to combat further spread of yellow fever mosquitos, residents are advised to dump all standing water commonly found in flower pots, bird baths, trash cans, old tires, and clean the containers thoroughly. Also, the water in pet’s dishes should be changed frequently and pools and spas should be properly maintained.

To avoid bug bites, residents are advised to make sure window screens are in good repair and to wear mosquito repellent while outdoors. “The Centers for Disease Control recommends using a repellent containing Picaridin, DEET, Oil of Lemon Eucalyptus, or IR3535,” according to the press release.

Please report any green pools, standing water, or day-biting mosquitoes to the District at 909-635-0307 or online at http://www.wvmvcd.org.
