Winter rain, spring heat bring a heavy mosquito season to the North Bay

The North Bay is experiencing a heavier and earlier mosquito season this year, thanks to major winter rains and warmer spring temperatures.

The atmospheric rivers that passed through the region earlier this year resulted in large areas of stagnant water, providing the perfect environment for adult mosquitoes to flourish with the recent heat spikes, according to the Marin/Sonoma Mosquito & Vector Control District.

The district has experienced a 119% increase in calls for service compared to this time last year — with one recent day registering almost 200 calls within the two counties, spokeswoman Nizza Sequeira said. The agency typically fields about 5,000 service calls a year on a range of pests from mosquitoes to yellow jackets to rodents.

The last time there was as large a call volume for the district was in 2016. The high season typically runs from mid-spring through October, Sequeira said.
