Removal · field guidance

Marking the bite site (skin pen, photograph)

Mark and photograph the bite right after removal so you can track expansion of any rash over the next 30 days.

Steps

01
After removal and cleaning, circle the bite site with a fine-tip skin pen or surgical marker.
02
Photograph the marked site under bright, even light with a coin for scale.
03
Repeat the photo every 2-3 days for 30 days, in the same lighting and pose.
04
A bullseye or expanding red ring (erythema migrans) at 3-30 days is a reason to call a clinician.
05
Keep all photos in one phone album labeled with the date of bite.
