Are lone star ticks in your neighborhood?

Between 2006 and 2016, researchers received 8,608 ticks from 22 states in the U.S. [1] However, most of the ticks were collected in Monmouth County, New Jersey, where the investigators were located. Monmouth County has long been recognized as endemic for Lyme disease.

Researchers found that lone star ticks accounted for nearly half (48.1%) of the ticks submitted, “far outpacing encounters with I. scapularis (28.2% of submissions).”

The dog tick (Dermacentor variabilis) accounted for approximately 20% of ticks collected.

Most tick bites found on young children and seniors

The greatest number of ticks were removed from children ages 0 to 9 and adults age 50 and older. “These age groups were also more likely to submit partially or fully engorged ticks, suggesting increased risk of tick-borne disease transmission to these vulnerable age groups,” writes Jordan in the journal PLoS One.

Ticks collected at home

Ticks were more likely to be collected from an individual’s place of residence, rather than from a park or natural area. This was particularly true for individuals over 60 years of age.

The authors remind us of the risk of tick bites occurring even during “mundane activities like raking leaves or gardening in one’s own backyard.”

Tick stages and seasonal tick bites

Developmental stage of the ticks varied. “While I. scapularis submissions were split roughly 50–50 between adult females and nymphs, fully 61% of all A. americanum submissions were nymphal ticks.”

Given that black-legged (deer) ticks were submitted throughout the year, the authors warn readers “that fall and winter active I. scapularis females may play [a role] in disease transmission.”

Meanwhile, lone star and dog ticks were submitted most often in the spring and summer months.

This study offers us insight into the growing threat of the lone star tick, both at home and in our neighborhoods.
