Emergency rooms across the country are seeing a sharp rise in tick bite cases, with July 2025 already hitting the highest number of tick-related ER visits since 2017 -- and the month is only a week old.

“The best place for ticks is your armpits and groin because they are warm, moist, and a good source of blood,” says pest control expert Jordan Foster. These spots also have thinner skin and are dark and secluded, prime feeding environments for ticks, agrees dermatologist Purvisha Patel, MD, founder of Visha Skincare.
