The Asian longhorned tick (Haemaphysalis longicornis) was discovered in the U.S. in 2017, and it poses health threats to both animals and humans. A new guide in the Journal of Integrated Pest Management outlines the different management strategies that are being developed, and surveillance and prevention are key to reducing this non-native arthropod’s impact. Shown here are a nymph (left) and adult female. (Photo by James Gathany, CDC Public Health Image Library)
