Woodchips: A Natural Tick-Busting Solution for Outdoor Enthusiasts
As the Canadian spring and summer approach, outdoor enthusiasts eagerly anticipate the return to nature. However, the increasing prevalence of ticks poses a significant threat to both human and animal health. A recent study conducted by the University of Ottawa has uncovered a natural and sustainable solution to this growing concern: woodchips.
The study, spanning two years and implemented on two Ottawa Greenbelt trails, revealed that distributing woodchips along trail borders significantly reduces the number of blacklegged ticks. This simple yet effective method not only targets ticks where they live and feed but also offers an environmentally friendly approach to disease prevention.
The research team's innovative strategy involves using recycled ash tree woodchips from the NCC ash tree removal program, diverting land waste and providing a practical solution for land managers. By placing woodchips along trail edges, ticks are deterred from climbing blades of grass or low vegetation, thus reducing the risk of tick bites for hikers and other outdoor enthusiasts.
One of the most remarkable findings was the combination of woodchips with deltamethrin, an insecticide. When woodchip segments were target-sprayed with deltamethrin at the beginning of each season, the number of ticks was reduced by an astonishing 99 percent. This targeted treatment approach minimizes the impact on pollinators and other beneficial insects, making it an environmentally sustainable solution.
However, the study also highlights the importance of human behavior in the success of this method. The effectiveness of woodchips 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 preventive measures such as wearing repellent spray containing DEET or icaridin and conducting thorough tick checks.
The research team's findings have significant implications for disease prevention and control. By implementing integrated control strategies, such as the use of woodchips, we can effectively reduce the risk of tick-borne illnesses like Lyme disease. This approach, known as the One Health approach, targets multiple components of disease transmission, including people, the environment, and the animals ticks feed on.
Despite the challenges faced, such as the 2022 derecho storm disrupting field research activities, the study emphasizes the need for careful consideration of control interventions that alter the landscape. The feasibility of this method is most promising on wide, high-use paths with well-established tick populations, and it should be paired with a robust tick surveillance program for optimal results.
In conclusion, woodchips offer a cost-effective and environmentally sustainable solution to the growing tick problem. By adopting this natural approach, Canadians can better enjoy the outdoors while staying tick-safe. As the battle against ticks continues, innovative solutions like these will play a crucial role in preserving both human and environmental health.
