Are Lone Star Ticks in New Jersey? Where They’re Found
IN NEW JERSEY?
LONE STAR TICKS
ARE COMMON—AND INCREASING
Yes—lone star ticks are now common in parts of New Jersey and, in some areas, may outnumber blacklegged ticks.
In one New Jersey study, lone star ticks accounted for nearly half of all ticks collected—more than the ticks that transmit Lyme disease.
Studies confirm that lone star ticks are established in New Jersey and continue to expand in the region.
What the Data Shows About Lone Star Ticks in New Jersey
Between 2006 and 2016, researchers analyzed 8,608 ticks submitted from 22 states, with most coming from Monmouth County, New Jersey.1
Lone star ticks accounted for 48.1% of ticks submitted, compared to 28.2% for blacklegged ticks (I. scapularis).
Dog ticks (Dermacentor variabilis) made up approximately 20% of the ticks collected.
Where Are Lone Star Ticks Most Common?
Many exposures occur close to home, including in backyards and residential neighborhoods.
Ticks were more likely to be collected from an individual’s residence than from parks or natural areas.
This was especially true for individuals over age 60.
The authors note that tick exposure can occur during everyday activities such as gardening or yard work.
Who Is Most at Risk for Tick Bites?
The highest number of ticks were removed from:
- Children ages 0–9
- Adults age 50 and older
These groups were more likely to submit partially or fully engorged ticks, suggesting increased risk of disease transmission.
When Are Lone Star Ticks Active?
Lone star ticks and dog ticks were most commonly encountered in the spring and summer months.
However, blacklegged ticks were found throughout the year, including fall and winter.
This means tick exposure is not limited to warm-weather months.
Do Lone Star Ticks Carry Lyme Disease?
Lone star ticks are not considered primary vectors of Lyme disease, but they are associated with other conditions and may contribute to diagnostic confusion.
They have also been linked to alpha-gal syndrome, a rare red meat allergy.
For comparison, see Lyme disease symptoms guide.
Why This Matters
The growing presence of lone star ticks reflects changing tick populations in Lyme-endemic regions.
Understanding where ticks are found—and how exposure occurs—is key to prevention.
