Silent but deadly, ticks are the often underestimated, often undetected killer of the UK – particularly the deer, fox and hedgehog varieties. While usually not threatening on their own, the tiny insects often carry Lyme. Lyme disease is infectious and begins with a flat, circular rash around the area of the bite, followed by possible fatigue, swelling, headache, fever and – if left untreated – can cause potential heart issues, especially among the elderly. Furthermore, most people who are bitten by ticks and end up contracting Lyme disease often have no memory of the bite itself, making the tick a particularly insidious creature.
