20 million male mosquitoes will be injected into Fresno neighborhoods to kill other infected mosquitos

The mosquito releases started on 7/14/2017 and will continue for the next 20 weeks. By the end of it all, 20 million male mosquitoes will be injected into neighborhoods.

Every week for the next four months, Steve Mulligan will be collecting traps in yards across Fresno County measuring how well a massive bug campaign is advancing.

Mulligan is partnering with a company called Verily to release bacteria-infected male mosquitoes. The bacteria makes the males infertile, and the idea is that they will mate with the local population of wild females.

“The result of that mating is infertile eggs, the eggs will not hatch they will not produce offspring,” he explained.

The mosquito they’re targeting is the Aedes Aegypti – an invasive species hard to control and a carrier of deadly diseases including Zika.

Families say they’ve noticed these bugs attack in the day as well as night and are particularly aggressive. They say any new tactic helps.

“I feel a lot more mosquito bites and tingling on my legs, and I know when I look down that’s usually a mosquito swarming,” resident Monica Teran said.

The sterile male mosquitoes being released don’t bite, and over time, Mulligan hopes they will cut down the population.

“If we are successful, the number of eggs that hatch will be less and less,” he said.

And families in the neighborhood will have less bug bites. Because of these releases, there will be more mosquitos flying in the neighborhood.

But the male mosquitos don’t bite and cannot transmit diseases.
