Virginia, USA. The entire visual field here is about 3mm, so they are incredibly small. Note this one has been on the slide for a few days and has turned darker. I'm pretty sure this is a larval Amblyomma americanum, the lone star tick.
I picked out what I could and scrubbed with rubbing alcohol, then soap, but I still have dozens of itchy welts. It's rare that they carry disease at this stage, but I got some doxycycline to be on the safe side. I had permethrin on my shoes and pants but not my gloves, so live and learn.
Actually I saw the ticks first, the welts didn't appear until the next day. Not my photos but basically exactly like the pictures here: https://medauth2.mdedge.com/dermatology/article/253551/infectious-diseases/vesicular-eruption-secondary-bites-larval-amblyomma
Thanks. I’ve had welts like that show up randomly several times. Never figured out why. I think I’ll pay closer attention the next time and see what’s causing it for me.
