Found one on myself this morning and I haven't even been anywhere interesting. In fact, I suspect I picked it up on an overgrown riverside path in the middle of Bristol. Wherever it was, it must have been there since Tuesday but I only noticed it today, despite taking care to look. The last one I found, a couple of years ago, I also didn't notice till two days later – and also both were on my stomach, whereas I thought they preferred nooks and crannies. Which leads me to a number of conclusions:
I'm probably missing a few for each one I notice, cos it's easy to notice something on your stomach.
I wonder if they don't actually attach themselves till a day or two after jumping on board? Cos surely I'd have noticed it on my stomach before, it was there.
Or else maybe they were initially so tiny I didn't see them – although neither looked what I would call engorged when I found them.
Anyway, I tweezered this one out and probably did more damage to myself with the tweezers than the tick did.
