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 to humans. In addition to being uncomfortable and irritating, tick bites can carry a variety of diseases, including Lime Disease and must be treated correctly and monitored closely.
