Ticks are external parasites that feed on the blood of wildlife and hide in wooded and overgrown areas. They are known to carry and transmit disease to humans and domestic animals.
There are two main species of ticks people are likely to encounter, which are the Black Legged Tick (Deer Tick) and the Brown Dog Tick.
The Black Legged Tick (Deer Tick) has a body that is a flattened oval shape and has no hard shell. Its sharply pointed mouth-part is visible when viewed from above. They start between 1/8" and 1/16" and become much larger after feeding on blood.
The Brown Dog Tick is consistently 1/8" in size and can grow to be 1/2" after feeding on blood. It has a flattened body with mouth parts visible from above and the male has tiny pits scattered on its back.
