Woodchips Halt Ticks: Simple Trail Solution
24 May
Summary
- Woodchips on trails can reduce local tick populations.
- Untreated woodchips halved ticks; pesticide-treated halved them by 99%.
- Woodchips deter ticks by preventing vegetation growth on trails.
Researchers from the University of Ottawa have discovered that applying woodchips to forest trails can dramatically decrease local tick populations, offering a simple, low-tech strategy to reduce the risk of tick bites and Lyme disease. The study focused on two sites within Ottawa's Greenbelt, applying either untreated or pesticide-treated woodchips to sections of trails.
Results indicated a substantial reduction in ticks. Untreated woodchips cut tick numbers by approximately half, while woodchips treated with the pesticide deltamethrin achieved a remarkable 99% reduction. This effectiveness stems from woodchips preventing the growth of vegetation that ticks use to climb onto unsuspecting hikers and pets.
This method shows particular promise for wider, high-traffic trails with a significant tick presence. While pesticide-treated chips offer superior results, even untreated woodchips provide a notable benefit. Experts note that the pesticide used is safe for pets due to its adherence to surfaces. The federal government also suggests woodchip borders around lawns to create tick-unfriendly environments.
While reducing tick numbers is a positive step, further studies are needed to confirm a direct correlation with a decrease in Lyme disease cases. Experts emphasize that adherence to trails is crucial for the woodchips' efficacy, encouraging hikers to continue using standard precautions like insect repellent and tick checks.
