Covina's climate — a mild climate overall, though inland valleys run noticeably hotter than beach communities just a few miles away — 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.
Our approach starts with identifying every standing-water source and brush or tall-grass area on the property, since those are where mosquitoes breed and ticks wait for a host. We treat vegetation and resting areas with a barrier spray and apply larvicide to any water that can't be drained, repeating on a seasonal schedule for ongoing control.
