Greencastle's climate — a climate shaped by the region's flat, exposed farmland, prone to strong winds and rapid weather changes — 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.
Treatment combines a barrier spray applied to vegetation, fence lines, and other resting spots where adult mosquitoes and ticks congregate, with larvicide treatment in any standing water on the property that can't be eliminated outright. A single treatment typically provides several weeks of reduced activity, with a seasonal program recommended for consistent control.
