A recent study conducted by the University of Ottawa has revealed that applying woodchips to forest trails can significantly decrease the presence of ticks in the area, potentially lowering the risk of tick bites and Lyme disease for hikers. The research team focused on two locations within Ottawa’s Greenbelt: the Mer Bleue sector in the east and the Stony Swamp sector in the west.
In their experiment, the team treated 20 sections of trails, each measuring 50 meters, with either untreated woodchips or woodchips treated with the pesticide deltamethrin. The results showed that the use of untreated woodchips led to a 50% reduction in tick numbers, while the application of deltamethrin-treated woodchips resulted in a remarkable 99% decrease in tick populations, as stated by researcher Katarina Ost.
Woodchips are effective in deterring ticks because these tiny arachnids typically climb vegetation, such as grass, to attach themselves to passersby. By placing woodchips on the trails, the growth of the vegetation ticks use for climbing is inhibited. According to Ost, trails with high tick density are ideal for implementing this method on a larger scale.
It is emphasized that deltamethrin, the pesticide used, poses no threat to pets walking on the wood chips, as it remains stationary once applied. The Canadian government recommends creating a barrier of wood chips, mulch, or gravel around residential lawns to prevent ticks from surviving in the environment.
Dr. Christopher Labos, a cardiologist and epidemiologist at McGill University, highlights the importance of controlling tick populations to curb the transmission of tick-borne diseases like Lyme disease. While reducing tick numbers on trails is beneficial, further studies are needed to determine the direct impact on Lyme disease cases.
Labos also stresses the importance of adhering to safety measures, such as wearing protective clothing, using insect repellent, and performing tick checks, especially for individuals venturing off designated paths where woodchips are not present.
