And it just seems like we’re being inundated with this, especially the invasive kind.
Asian longhorned ticks (ALTs) have been spreading across the Eastern and Midwestern U.S. since at least 2017, according to the Center for Disease Prevention (CDC), and the pests’ numbers are now on the rise in Ohio—a recent study from the Ohio State University reveals. According to the study’s authors, 9,287 invasive ticks were removed from a farm in eastern Ohio in the summer of 2021 after three cattle were reported dead from tick bites by the landowner.
During the study—lead-authored by Ohio State Assistant Professor of Veterinary Preventive Medicine Risa Pesapane—scientists continued to monitor the invasive tick population after most of the pests were killed off with pesticides. They found that the Asian longhorn ticks returned to the pasture and continued to spread in June 2022, despite the tick control efforts undertaken in 2021.
“You cannot spray your way out of an Asian longhorned tick infestation,” Pesapane said in a Nov. 3 news release. “They are going to spread to pretty much every part of Ohio and they are going to be a long-term management problem. There is no getting rid of them.”
Pesapane said that the cattle killed during the 2021 ALT infestation in eastern Ohio sustained thousands of tick bites. “One of those was a healthy male bull, about 5 years old,” she said in the press release. “Enormous. To have been taken down by exsanguination by ticks, you can imagine that was tens of thousands of ticks on one animal.” The term “exsanguination” refers to the action of draining a person, animal, or organ of the blood needed to sustain life.

According to Pesapane, the invasive tick’s rapid spread lies in its ability to reproduce asexually, without mating. “There are no other ticks in North America that do that. So they can just march on, with exponential growth, without any limitation of having to find a mate …
Great. Does anything good come out of Asia?
If it isn’t ticks, it’s chiggers. This one is especially dangerous to humans.
Wildlife researchers at the University of North Carolina at Greensboro found a novel pathogen for the first time in North Carolina that is carried by chiggers.
Bacteria called Orientia tsutsugamushi causes the disease scrub typhus, which is spread to people through bites of infected chiggers, according to the Centers for Disease Control and Prevention.
“That is a disease that has never been described in North America or in the Americas altogether,” Dr. Gideon Wasserberg, an infectious disease expert who works in the UNCG Department of Biology, said.
Symptoms include:
- a dark scab at the site of the bite
- confusion
- fever
- chills
- headache
- body aches
- rash
- larger lymph nodes
In some extreme cases, it can lead to organ failure.
Just great.
I’m happy that the suffering from summer is over and we’re facing some cold weather now, but summer will be back with a vengeance, so stay diligent.
