- Ticks range in size from 2 to 3.5 mm.
- Ticks are arachnids, like spiders, and have eight legs.
Ticks are parasitic insects that survive by taking blood from mammals, birds and reptiles. Ticks are pests that many pet owners are familiar with because they are the most common pests of domesticated dogs in the southern U.S. It is also common for ticks to attach and feed off of to humans. In addition to being uncomfortable and irritating, tick bites can carry a variety of diseases and must be treated correctly and monitored closely.
A hard tick has a tough shield like shell and they are usually shaped like a flat seed before feeding. Soft ticks do not have a hard shield and are shaped like a raisin. Both are usually reddish-brown in color.
