How to “Fight the Bite”

The Mosquito and Vector Management District ofSanta Barbara County is requesting the public’s help after the discovery of an invasive mosquito species on October 16 in the area of  N. Turnpike Road and Calle Real.

According to the Mosquito and Vector Management District, Aedes aegypti is s currently threatening to establish itself in the region. The first invasive species, Aedes notoscriptus, the Australian backyard mosquito, was detected earlier this year in Santa Barbara’s West Side neighborhood in March and the Mesa neighborhood in June.

Because they frequently target people around the feet and lower legs, residents in areas where these pests have established often refer to them as “ankle biters.”

“When population numbers are low, we still have an opportunity to eliminate these highly bothersome, introduced insects from our neighborhoods. By enlisting the public’s help, we can ensure these species do not become established in Santa Barbara County,” said Brian Cabrera, General Manager of the Mosquito and Vector Management District. “You can be part of the solution by eliminating any sources of water where eggs can be laid and by contacting the District if you suspect you are being bitten by these mosquitoes.”

In Australia, Aedes notoscriptus is the primary carrier of dog heartworm. While a native mosquito species serves as the primary vector for dog heartworm in California, pet owners are encouraged to ensure their pets are protected. Preventative medications are readily available through local veterinarians.

Both Aedes species prefer to stay close to human dwellings. Females lay their eggs in almost anything that holds stagnant water—including buckets, tires, birdbaths, pet dishes, potted plant saucers, clogged yard drains and even water trapped inside plants like bromeliads.

Remarkably, the larvae of these species can complete their development in the amount of water that fills a single bottle cap, and their eggs can resist drying out for many months.

How Residents Can “Fight the Bite”

The District urges all Santa Barbara County residents to take the following preventative measures:

• Dump and Scrub: Remove all sources of standing water inside and outside your home. Scrub the sides of containers to destroy clinging eggs.
• Protect Your Home: Close open doors and ensure all window and door screens are in good repair.
• Protect Yourself: Wear long-sleeved shirts and long pants, and apply EPA-approved insect repellent when outdoors.
• Protect Your Pets: Consult your veterinarian to confirm your dogs are on heartworm prevention medication.
