The lone star tick, whose bite can cause alpha-gal allergy to meat, is present in the Washington area, but it is not an urban pest. “If you live and work on Capitol Hill, you probably won’t get it,” says University of Virginia immunologist Scott Commins. “People we usually see in our clinic either live in Northern Virginia and work in D.C., or their hobbies take them outside of D.C. on the weekends.”

The tick’s name is a reference not to Texas but to the white dot on its back.
