There was a report on the new last night that there has been an increase in mosquitoes testing positive for West Nile in Orange County. It's not Zika, but you probably don't want that either. While the risk of contracting Zika in So Cal in microscopic at best, every time there is a report of a new locale where someone has contracted it, someone had to be the first person. For peace of mind why not pack some bug spray? I have some permethrin spray left over from a previous international trip. I'm planning to treat a few outfits for outdoor activities for the rest of the summer. The cost and time to do that are minimal.
