Tick Control Study Project Study efficacy of combined use of Met52® ( a fungal pesticide) and Tick Control System® (Bait Boxes) against blacklegged tick Study Sites: Fairview Park, Wolfe’s Pond Park, and Conference House ParkProject Duration: 2019 – 2021Products to Be Tested: Met52® (a fungal pesticide) and Tick Control System ®

Tick Control System® Child-resistant box containing a bait block Small rodents entering the box are treated with Fipronil (a pesticide) Fipronil kills ticks for 2-4 weeks

Met52® - Biological Pesticide Contains spores of the fungus Metarhizium anisopliae . Ticks are usually killed within a week after exposure to the spores. Metarhizium o ccurs naturally in forest soils Safe product for humans, pets and other mammals. Approved by EPA for use in residential and non-residential areasTicks infected by the fungi Metarhizium anisopliae
