The Tick Project in Focus


Explore results from The Tick Project, a six-year study that was the first to test if environmentally-safe interventions could reduce ticks and the diseases they carry at the neighborhood level. In this virtual event, project directors Felicia Keesing of Bard College and Rick Ostfeld of Cary Institute will review the study design, methods, results, and lessons learned along the way, with ample time for audience Q&A.

The Tick Project was conducted in Dutchess County, New York, home to some of the nation’s highest rates of Lyme disease. The study was designed to determine whether Met52 fungal spray and Tick Control System bait boxes, used separately or together in yards, could reduce tick numbers, tick encounters, and neighborhood risk of contracting Lyme and other tick-borne diseases. More than 2,380 people (and 849 pets) participated, representing 24 neighborhoods. Dozens of researchers monitored ticks on participating properties and households completed biweekly surveys about tick encounters.

After processing mountains of data, long-awaited results are in. TCS bait boxes were found to reduce the number of ticks in people’s yards by about half, while the Met52 fungal spray had little effect. Neither control resulted in fewer tick encounters by people or a reduction in Lyme and other tick-borne diseases in treated neighborhoods. Incidence of tick-borne diseases in pets was lower by about half on properties that were treated with either the boxes, the spray, or both.

The Tick Project set a gold standard for methods in the fields of disease ecology, vector control and integrated tick management. The study is a reminder of the importance of personal protection and vigilance in the fight against tick-borne disease.

The Tick Project was conducted in partnership with Bard College, Centers for Disease Control and Prevention, New York State Department of Health, and Dutchess County Department of Behavioral and Community Health. The research was made possible, in part, by a grant from the Steven and Alexandra Cohen Foundation and the support of a network of generous donors.
