Willow's climate — a humid climate with hot summers and long, genuinely cold winters, more severe the farther north you go — plays a direct role in mosquito and tick pressure, since both pests are most active in warm, humid conditions. Yard features like standing water, dense brush, and tall grass all increase risk.
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.
