Between the months of April and October and on mild winter days small spider-like Ticks live on heathland particularly where there is bracken and very occasionally they can attach themselves to human skin. Fortunately such occasions are rare .Although walkers may wear what clothing they wish official medical recommendation is that when walking in such areas walkers should wear long sleeve shirts and long trousers tucked into socks. We already recommend wearing stout shoes. We must again stress that such occurrences are rare but have a duty to inform you.
