Deer Tick (Black-Legged Tick) Control:

Understanding the Deer Tick Threat in Middle Tennessee

While deer ticks (Ixodes scapularis), also known as black-legged ticks, are less common in Middle Tennessee than lone star or American dog ticks, their presence poses a unique and serious health concern. As the primary vector for Lyme disease in the United States, even a small population of deer ticks demands attention and professional management.

At Armor Termite and Pest Control, we’ve observed an increase in deer tick encounters in the Mt. Juliet and greater Nashville areas, particularly in properties adjacent to wooded areas and those frequented by white-tailed deer. Understanding and controlling these ticks is crucial for protecting your family from Lyme disease and other tick-borne illnesses.

Why Deer Ticks Matter

Despite lower numbers compared to other tick species, deer ticks present outsized risks:

Primary Lyme disease vector in North America
Year-round activity possible in Tennessee’s climate
Small size makes detection difficult
All mobile stages (larvae, nymphs, adults) can transmit diseases

The Tennessee Department of Agriculture urges awareness during tick season, noting risks to livestock, pets, and people. For additional guidance, see Livestock and Pet Owners Should Be Aware of Tick Season in Tennessee from the Tennessee Department of Agriculture.
