A male longhorned tick is a rarity. Reproducing by parthenogenesis, females clone themselves laying hundreds of eggs and individually creating an entire population in any given area. Considered a pest, there is no evidence that Asian longhorned ticks transmit any infection to people or dogs here in the U.S. However, they can transmit disease to cattle, farm animals and wildlife.

According to APHIS data and in laboratory settings, Asian longhorned ticks were NOT found to be competent vectors for Borrelia burgdorferi (Lyme disease), Anaplasma phagocytophilum (human granulocytic anaplasmosis), or Franciscella tularemia (tularemia). However, they were found to be capable of transmitting Rickettsia rickettsi (Rocky Mountain Spotted Fever), Heartland virus (HRTV), Powassan virus (POWV), and Theileria orientalis Ikeda strain (cattle theileriosis).
