The black-legged tick, also known as the deer tick, is a small arachnid that is commonly found in wooded and grassy areas. These ticks are known for their role in spreading diseases, particularly Lyme disease, which can cause serious health issues in humans and pets. They are typically active during warmer months and are most often found on animals like deer and rodents. To protect yourself from black-legged ticks, it's important to wear long sleeves and pants when hiking in tick-prone areas. Additionally, using insect repellent containing DEET can help deter these pests. Regularly checking for ticks after outdoor activities is crucial, as early removal can reduce the risk of disease transmission.
