I previously worked in public radio in Oklahoma and Colorado, but I’ve fallen in love with the mountains and beaches of California. If you listen closely when I’m live on the radio on 89.3 KPCC, you may hear my three cats make an appearance — despite my best efforts to keep them quiet.

A 20% DEET Premium Controlled-Release Lotion will work well against mosquitoes, but Dr. Zimring says he prefers the 20% Picaridin lotion since it also protects against ticks, gnats, chiggers, and flies. (In both instances, he recommends Sawyer brand.)
