TickCheck can test your tick and determine whether it carries the bacteria that transmit Lyme disease and other tick-borne infections.
There are hundreds of species of ticks throughout North America. Many species feed solely on wild animals or are found in very specific habitats and are rarely encountered by humans. Other species are commonplace and can be found inhabiting areas frequented by humans and their pets.
The most notorious tick species that come into contact with humans are the deer tick, American dog tick, lone star tick, brown dog tick, and Western blacklegged tick. These tick species have similar life-cycles and habitats, but each transmits a unique set of pathogens and inhabits different geographical regions. Ticks go through four life stages: egg, larva, nymph, and adult.
Larvae, nymphs, and adults all feed on the blood of vertebrate hosts and are capable of becoming infected with a pathogen while feeding. At their next blood meal, they may then transmit the acquired pathogen to the new host they are feeding on. It is important to be able to recognize the life stage of a tick in order to be protected from tick-borne disease. Learning about the ticks that inhabit your area and how to identify them, can help to protect you and your family from exposure to tick borne disease.
The following guide will be helpful in identifying what type of tick has been encountered. While there are hundreds of species of ticks around the world, the majority of tick-borne diseases transmitted to humans and pets are carried by three main tick groups: blacklegged ticks including the deer tick , dog ticks, and lone star ticks.
You can use this chart to identify the five most common variations of these tick types. Click on the tick name or image for a more detailed description. At TickCheck, we can test all of these species of ticks for all of the most common tick-borne diseases with over The deer tick, also called the blacklegged tick, is one of the most common ticks found in the United States. Deer ticks are the smallest tick in North America, with adults growing to about the size of a sesame seed. Look how small this blacklegged tick nymph is compared to the thumbnail.
We found it on a drag cloth while we were collecting ticks out in the woods. Can you find the tiny blacklegged tick larva near the knuckle of this hand? Larvae are the smallest life stage of tick that develop from eggs. These ticks have been lined up next to the thumb so you can see their relative sizes. From left to right are the blacklegged tick deer tick larva, nymph, adult male, and adult female followed by the American dog tick wood tick adult female and adult male.
After ticks are collected out in the field, they are brought back to the office for identification under the microscope. This picture focuses on a blacklegged tick nymph — its large mouthparts are important for biting and staying attached to a host for the entire feeding period, which usually lasts days.
Here is an adult female blacklegged tick on a thumb. Adult blacklegged ticks are about the size of a sesame seed. This picture shows a blacklegged tick nymph near a fingernail. Nymphs are smaller than adult ticks and are about the size of a poppy seed. This MDH staff person is dressed in white to more easily spot ticks that may grab and crawl onto them while out in the woods.
He is pointing to two adult female blacklegged ticks left and one male blacklegged tick right on his pant leg.

Tick Monitoring Do you have a tick that you want to be identified? Ticks In Minnesota, there are about a dozen different types of ticks. The lone star tick is shown in the upper left of this photo and is a little smaller than the American dog tick but larger than the blacklegged tick Blacklegged Tick Life Cycle Blacklegged ticks live for about two to three years. Feeding and blood meals Blacklegged ticks feed on blood by inserting their mouth parts into the skin.
They are slow feeders and will usually feed for days. In order to spread disease to a human or animal, a tick needs to be infected with a disease agent and it needs to be attached to the host for a certain amount of time.
If the blacklegged tick is infected, it must be attached for hours before it transmits Lyme disease. Less common tickborne diseases, such as anaplasmosis, may take less time.
