Outdoor pest pressure in Castella is seasonal but predictable: mosquitoes track standing water and humidity, ticks track brush and tall grass. an inland valley climate far hotter in summer and foggier in winter than California's coastal regions determines how long that season runs.
Mosquito and tick control here is about disrupting the life cycle at multiple points: larvicide in standing water stops mosquito breeding before it starts, and a vegetation barrier spray targets adult mosquitoes and ticks where they rest during the day. Seasonal retreatment keeps protection consistent through the warm months.
