Learn More About American Dog Ticks

The American dog tick is the largest of the eastern wood ticks. Ticks are parasites, and they must find a mammal host for blood. American Dog Ticks will feed on humans and medium to large mammals such as raccoons and dogs. American Dog Ticks are not easily injured and have few predators. They can transmit diseases such as Rocky Mountain spotted fever. Protect yourself and your family by contacting us for tick control services.

Pest Identification


1/8 - 1/4 in.


Reddish brown

Body Structure

Flat body with eight legs.


Female adults when fully gorged with host blood may produce as many as 500,000 eggs, laying them in secluded cracks and crevices. The female coats the eggs in a secretion to keep them from drying out, and then dies after completing this process, which may take as long as 15 days. When the eggs hatch, the larva go in search of food, gorging themselves on a host until molting, upon which they enter the nymph stage. Here again, nymphs will seek a new host, gorging themselves on blood until molting and emerging as an adult. In indoor/enclosed environments, young ticks will gorge on the same animal instead of finding new hosts. Furthermore, the brown dog tick is unique in that it can complete the entire life cycle indoors.

Habitat & Behavior

In the wild, brown dog ticks can be found residing on tall grasses or vegetation, where they wait to attach themselves to a passing mammalian host. While they will feed on animals such as rabbits or deer, they prefer dogs, hence the name. Generally, adult brown dog ticks will attach themselves just behind a pet’s ears or between its toes. Initially infestation may go undetected. It is often during the larval stage, when the undeveloped young disperse in search of food, that one will see thousands of offspring, crawling in and around a pet’s bedding area. Like its counterparts, the brown dog tick is also a vector pest, capable of transmitting disease, including Rocky Mountain Spotted Fever.

Prevention & Treatment

Checking pets and their sleeping areas for ticks is a good preventative measure. Likewise, if spending time outdoors, spraying your clothes and shoes with a pest repellent containing DEET will help protect you from the parasites. Although brown dog ticks more commonly feed on pets rather than humans, if you find a tick on your body, remove it by using tweezers, pulling it from your body as close to its mouthparts as possible. Should you experience any fever, nausea, profuse sweating, or adverse reaction to the bite, seek medical attention immediately. If you suspect an infestation in your home, refrain from do-it-yourself treatments. Brown dog ticks multiply quickly and are difficult to eradicate. Contact a pest control professional to inspect your home and implement a proper course of treatment. Find out more about tick prevention and extermination options.
