Just back from 9 days away, the first 4 of which I was walking in southern(ish) Snowdonia with 3 nights wild camping, and I was armed with a newly purchased Trix Tick Lasso, because the little horrors absolutely love me!
True to form, I got them on my upper forearms which were exposed with sleeves rolled up, under my watch strap, and one on an elbow. More were around my biceps under the sleeves, and on my chest. Even though my trousers remained tucked into my socks except at bedtime, some got onto my thighs.
I gave up counting, there must have been around 20, found in 2 days. 4 of these were what I would call "normal" size (adults?) and the lasso was effective at removing these, although it neeeds a steady hand and the tick needs to be in a place where you can see what you're doing. I found it helped if I stretched my skin away from the tick with one hand while operating the lasso with the other.
The greater majority, though, were the smaller-than-a-pinhead little black dots (juveniles?) and the tool was no use at all at removing these, they were too small to lasso. I had no choice but to resort to my old method of picking them off with the blunt side of the point of a knife.
