The American Dog Tick prefers dogs (shocker) as their host, but they will gladly feed on larger animals, including humans. This tick goes through an egg, larva, nymph, and adult stage during its lifetime. Although they can be foundyear-roundd, adult dog ticks are usually found between April and May. Dog ticks do not transmit Lyme disease, but they are the main carrier of Rocky Mountain spotted fever in the Midwest states. Outdoor tick control is difficult, and while there are some insecticides labeled for outdoor tick control, the most effective way to discourage a large tick population is to change the habitat. Ticks generally thrive in bushy, heavily wooded areas, so reducing that “prime real estate” on your property would be wise if you have tick issues.
