The West Nile virus arrived in Fresno County in 2004 The Consolidated Mosquito Abatement District has been busy ever since.
"Every year it is here, and although we are monitored, we always collect West Nile virus mosquitoes in this area," said Katherine Ramirez from the Consolidated Mosquito Abatement District.
Employees go into pond pools and neglected swimming pools and use fish or larvicides to control the mosquito population.
However, some infected insects always slip through the shield.
This year, they have collected 46 Culex mosquitoes with serious viruses.
43 had West Nile virus; Three of them had encephalitis in St. Louis.
"We spray in a very low-volume area when we find infected mosquitoes, and we continue to monitor to make sure the mosquito population has declined," Ramirez said.
So far, the people of Fresno County have been taken to safety.
But their accumulation of infected Culex mosquitoes has now spread to Fresno, Clovis and Sanger, putting people in danger of getting an infection that causes flu-like symptoms leading to paralysis and trembling.
And the mosquito Aedes aegypti can be even worse.
She may carry Chikungunya, Yellow Fever, Dengue Fever and Zika and they are much more hungry than Culex mosquitoes, which may even eat blood once every two weeks.
"It's an extremely annoying mosquito, it bites repeatedly, and often someone thinks they have a big mosquito problem because the number of stitches is felt," Ramirez said.
Mosquito Repellent District te I partnered with one arm from Google to conduct an experiment to reduce Aedes aegypti, which will dump sterile male mosquitoes into neighborhoods, and it shows positive results.
It is said that 95% fewer women were found in these areas, and women are the only mosquitoes biting.
The biter is still out there, so insect repellent is a necessity, especially at dusk and dawn.
