The Sacramento-Yolo Mosquito and Vector Control District is urging local residents to help prevent the spread mosquitoes, following the discovery of an invasive species of the insect that was found last month in Citrus Heights.
The species, known as the aedes agypti mosquito, has previously been found in several other California cities, but district officials say this is the first instance of these mosquitoes being spotted in Citrus Heights.
There are a few distinctive characteristics of this species that set them apart from native mosquitoes. Officials say the aedes agypti are very aggressive daytime biters, while those native to northern California only bite at dusk or dawn. They also tend to live in urban areas and bite the ankles of people.
This species is also a container-breeding mosquito, spokeswoman for the district Luz Maria Robles told the Sentinel in a recent interview.
“It thrives in backyard sources,” she said. “Buckets, tires, pet bowls; it lays it eggs on the sides of containers. The eggs are resistant to drying out and can survive for many months.”
After the mosquitoes are established in any given area, they are extremely difficult to control, which is why residents are urged to notify the district if they find the species living near their homes.
Last month, Placer County officials first discovered the invasive species in their district, which led local officials to do some searching in Citrus Heights where the mosquitoes were found in a watering can.
The district has been trying to find the scope of the infestation, which has found to be primarily in a small area in the northern portion of Citrus Heights. It is contained as of now, but can spread very easily.
Though Robles assured that the species found in Citrus Heights is not carrying the Zika virus, they have the potential to, as well as dengue and chikungunya, though all these diseases are imported cases from travelers.
Symptoms from these viruses only tend to last a few days, and up to a few weeks. Symptoms can include fever, rashes, headache, and joint and muscle pain.
The district is taking action by doing door-to-door campaigns, and asking homeowners if they can inspect their yards. They have also been setting traps to see the scope of how far the infestation can be, as well as conducting treatments like spraying the grounds to kill any eggs.
“Public cooperation is key,” Robles said. “We’re asking residents to report day-biting mosquitoes to us, so if you notice you’re being bitten more than usual, especially during the day, please give us a call.”
She also said residents should be vigilant about the water in their yards, making sure no stagnant water is left outside. Residents are also asked to be cooperative about home inspections, so the district can contain the problem.
“These mosquitoes don’t fly very far, so if we find a home that has them, it could be likely that their neighbors on either side could have them too,” she said.
Mosquitoes can be reported by calling (800) 429-1022 or by requesting service online at www.FIGHTtheBITE.net.
