The Lancaster County Facilities Management Mosquito-Borne Disease Program will be conducting this truck-mounted ultra-low volume (ULV) mosquito control operation. The Lancaster and Lebanon County Mosquito and Tick Borne Disease Control Specialist and Mosquito Control Technician will be on site for the application. Lancaster County’s business license is BU 9444, and the product used will be Aquaduet applied at a rate of 1.0 fluid oz/ac. This product is designed to provide quick knockdown and effective control of adult mosquitoes. The control event is performed by way of an Ultra-Low Volume Truck Mounted Spray. Our sprayer puts out the product in microscopic droplets (approximately a shot glass of product is applied over the distance of a football field). Because the droplets are so small, they degrade quickly and are only “potent” for roughly 20 minutes before they begin to degrade. Therefore, it is unable to adhere to vegetation/leech into groundwater, etc. This protects non-target species such as pollinators and aquatic life. Additionally, we specifically deploy this product after dusk when the target mosquito species is most active and pollinators are not. We understand the role pollinators play and want to ensure that we do them no harm while also protecting public health.

Warwick Township and Lititz Borough residents should protect themselves from mosquito bites by wearing or implementing some form of repellent, including wearing long sleeves and pants when outside. Additionally, residents and homeowners should be vigilant of standing water, including artificial containers holding water such as buckets, clogged gutters or tarps. Something as small as a soda bottle cap filled with water can breed mosquitoes.
