Appearance

The American Dog Tick (Dermacentor variabilis), also known as the wood tick, is characterized by its medium brown body adorned with distinctive white patterns on its back. They primarily infests dogs but is also known to bite other mammals, including horses, coyotes, raccoons, cattle, and even humans. While it is rarely found inside homes or buildings, it can enter when carried by infested pets or people.

American Dog Tick Life Cycle and Behavior

The American Dog Tick undergoes several life stages: egg, larva, nymph, and adult. The immature stages (larvae and nymphs) mainly feed on small rodents, such as mice, rabbits, moles, shrews, and some small birds. In the spring, they lie in wait on grasses and low vegetation, ready to latch onto a passing host.

After mating, the female tick feeds for about 10 days, becoming engorged with blood before dropping to the ground to lay her eggs. A single female can produce several thousand eggs, typically in clusters of 800 or more, before dying. The complete life cycle of the can take anywhere from four months to over a year, depending on environmental conditions. Notably, both larvae and nymphs can survive for over a year without feeding, while adult ticks can also live for extended periods without a blood meal.

To manage American Dog Ticks, regular grooming and tick checks on pets are essential, especially after outdoor activities. Utilizing tick prevention products, such as topical treatments and collars, can help protect your pets.

If you find ticks on your pets or in your home, prompt removal is crucial to minimize the risk of disease transmission.
