Welcome to August -- where the sun is sizzling, and mosquitoes are lurking in cool, backyard ivy.

Last week, (August 3-7), two more SGV mosquito samples tested postive for West Nile virus (WNV) by our Surveillance Department. This is the first WNV confirmation of 2020 in West Puente Valley and the city of Rosemead.

While we can expect this number to rise, there are easy ways to combat these pesky insects.

Still feeling like there's more that can be done? -- You're right!
