Outdoor pest pressure in Nine Mile Falls is seasonal but predictable: mosquitoes track standing water and humidity, ticks track brush and tall grass. a continental climate with genuine seasonal extremes, far drier than western Washington year-round 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.
