Mercer County Mosquito Control will be conducting aerial larval mosquito control operations throughout the county by way of helicopter. Due to the size and inaccessibility of many mosquito breeding habitats, these areas are routinely treated when mosquito larvae are present in the standing water.
Residents may observe our helicopter flying at low altitudes near residential areas while positioning to approach nearby treatment sites.
PLEASE NOTE: THIS IS NOT an area-wide adult mosquito control (“mosquito spraying”) operation.
Aerial larviciding involves the use of Bti-based, target-specific, biorational granules applied directly over standing water to help prevent larval mosquitoes from developing into biting adult mosquitoes.
