It turns out this winter's split personality will lead to some strong divergences in pests. Out on the West Coast, a warm winter and spring is likely going to result in pests emerging earlier, with large amounts of ticks and ants predicted. The drought, which remains a huge issue in California, means fewer places for mosquitos to breed, but because of that, more bloodsuckers will be concentrated in a few areas (likely near people, because we like water too). These close quarters means a higher chance that mosquitoes will transmit the deadly West Nile Virus. Last year, California saw a record number of cases.
