What is a tick bite?
A tick is a small brown bug that attaches to the skin and sucks blood for 3 to 6 days. The bite is usually painless and doesn’t itch. The wood tick (or dog tick) which transmits Rocky Mountain spotted fever and Colorado tick fever is up to 1/2 inch in size. The deer tick which transmits Lyme disease is the size of a pinhead. After feeding on blood, both of these ticks become swollen and easy to see.
