An invasive exotic tick species spreading in New Jersey has turned up in Monmouth County, marking the sixth county to see the tiny parasite, officials said Tuesday.
The Longhorned tick, also known as the East Asian tick, was discovered on the floor of a home with a dog, but it was not clear if it was ever attached to the pooch, according to the state Department of Agriculture. Another dog also recently visited the house.
"It is important for the public to continue to submit tick samples as this will allow us to identify new areas where this tick may be located," Dr. Manoel Tamassia, the New Jersey Department of Agriculture State Veterinarian, said in a statement. "Only with this knowledge, will we be able to make decisions at local and national levels."
This invasive tick is cloning itself. Researchers are racing to contain it.
The tick has previously been found in parks, including Davidson Mill County Pond Park in Middlesex County and Watchung Reservation, Houdaille Quarry Park, and Briant Park in Union County, according to officials.
Longhorned ticks have also been confirmed in New York, North Carolina, Virginia, West Virginia and Arkansas. How the tick, which is native to China, Russia and the Korean Peninsula, arrived in the United States remains a mystery, but officials believe it could have arrived on a dog.
Last August, a farmer went to a Hunterdon County health office covered in thousands of the ticks after she was sheering an Icelandic sheep, named Hannah. Experts identified the Longhorned tick, which was not previously reported in the United States.
"Various local, state, and federal animal health agencies, as well as Rutgers Center for Vector Biology, continue to work together to identify the range of the Longhorned tick in New Jersey," state officials said in a news release. "Longhorned ticks that have been collected in New Jersey thus far have tested negative for various human and animal pathogens."
Similar to deer ticks, the nymphs of the Longhorned tick are extremely small and resemble tiny spiders, the agriculture department said. They can easily go unnoticed on animals and people, and have been known to spread disease in other countries. The tiny ticks infest a range of species, including humans, cats, dogs and livestock.
State agriculture officials setup a phone line for anyone who finds a tick on themselves, pets or livestock and has questions: 1-833-NEWTICK (1-833-639-8425. Tick reports can also be submitted at the NJDA website.
