Types of Ticks Found in the U.S. There are many different species of ticks found around the world but there are five species which are most common. These types of ticks are: Deer Tick (Ixodes scapularis): Also known as the blacklegged tick, the deer tick is most commonly found in deciduous forest areas.
In most circumstances, it is not the tick bite but the toxins, secretions, or organisms in the tick's saliva transmitted through the bite that cause disease. Ticks (and mites) are arthropods, like spiders. There are more than 800 species of ticks throughout the world. Many organisms that bite humans for a blood meal are not ticks and should not be confused with ticks. Some common examples are mosquitoes, bedbugs and fleas (these are insects, not arthropods).
