Please be aware that ticks are common on Seili Island. To reduce the risk of tick bites, avoid areas with high grass or thick vegetation and stay on the roads and lawns. Conduct a daily check for ticks, especially in areas with thin skin.

If you discover an attached tick, tweezers for safe removal can be obtained at the main building. If you encounter any difficulties in detaching the tick, please contact our staff for assistance.
