Woodchips: A Natural Defense Against Ticks
As the Canadian spring and summer approach, many of us eagerly anticipate outdoor adventures like hiking, biking, and gardening. However, the increasing prevalence of ticks due to climate change poses a significant threat to our enjoyment of these activities. A recent study by the University of Ottawa has uncovered an innovative solution: woodchips as a natural and sustainable way to keep ticks off trails.
The study, spanning two years and conducted on two Ottawa Greenbelt trails, revealed that distributing woodchips along trail borders significantly reduced the number of blacklegged ticks. This simple yet effective method not only targets ticks where they live and feed but also contributes to environmental sustainability. By using recycled ash tree woodchips from the NCC ash tree removal program, the study diverts land waste and provides a practical solution for land managers.
The research team also experimented with targeted spraying of deltamethrin, an insecticide, on the woodchip segments. This approach achieved an impressive 99% reduction in ticks, while minimizing the impact on pollinators by avoiding broadcast spraying into surrounding vegetation. This targeted treatment holds promise as a cost-effective and environmentally friendly method to reduce ticks.
However, the study also highlights the importance of human behavior in the success of this intervention. The method relies on people staying on marked paths and avoiding off-trail areas where ticks may be present. While this is a practical solution, it should be complemented with other measures like wearing repellent and conducting tick checks.
The challenges of the project, including the 2022 derecho storm and the need for ATV access, emphasize the importance of carefully considering the feasibility of control interventions in the face of increasing climate change impacts. The study's findings suggest that woodchips could be a valuable tool in reducing tick populations on woodland recreational trails, especially in peri-urban settings.
In conclusion, this natural approach to tick control offers a promising solution for Canadians to enjoy the outdoors while staying safe from ticks. By combining woodchips with other preventive measures, we can create a more sustainable and effective strategy to combat the rising threat of ticks.
