Topline:

Rain impacts: General Manager Susanne Kluh said the rain likely refilled mosquito breeding sources that the district emptied over the summer, so technicians are out checking areas. Mosquitoes develop slower in cold weather — but we’re warming up over the next few days.

What you can do: Aside from clearing sources of standing water, Kluh said you should reach out to vector control if you see something like a street gutter that’s not draining properly. She's also concerned about neglected pools and is encouraging folks to call in anonymously if needed.

“If you live on the second floor and you see one of your neighbors has a swimming pool that’s green and algae ridden,” she said, “that’s probably producing mosquitoes.”

The health hazard could affect your neighborhood. You can report that by submitting a service request to your local vector control district or contacting the county health department.

Why this matters: Kluh said this year’s mosquito season has been mild in terms of West Nile virus, but there’s still a risk of spread. This is also the time of year where Aedes mosquitoes transmit the virus that causes dengue. The county health department just reported its first locally-acquired case this year on Wednesday.
