Identifying it in New York

Larger than a blacklegged tick and patterned with off-white marbling on the shield, the American dog tick is the one most often found already engorged on a scalp or a dog. The bite is usually painless, so discovery is by touch rather than by symptom.

Locally, the species most often confused with it are honey bee sting, bald-faced hornet sting, carpenter ant bite — all of which are also recorded in New York.

Seek medical care if

  • fever with a rash starting on wrists and ankles — treat as urgent
  • severe headache or muscle pain days after a bite
  • unsteady walking or weakness while a tick is still attached

Season in New York specifically

Records in New York concentrate in April to July, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in New York runs April to October.

Because grassy fields, trail edges and scrub east of the Rockies, plus parts of the Pacific coast, exposure in New York tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.

Care

  1. remove promptly with fine-tipped tweezers
  2. wash and note the date
  3. seek care early if fever develops — Rocky Mountain spotted fever is treatable but time-critical
