This Pacific Coast Tick is a three host tick which commonly feeds on rodents, especially squirrels as subadults, and on horses, deer, and humans as adults. This is one of the most widely distributed ticks in California and is found throughout most of the state. So, for those of us who have deer or squirrels in the garden, a tick check might be a good idea after working or walking in tall grass.
