What's the best way of handling it if you find one on you?
If it is on your arm or leg, you could move to let it run off on its own. Flicking it off or gently brushing it off has worked. Don't trap it or press on it if that can be avoided.
If they are in your clothes with you, it may be necessary to carefully remove the garment and shake them out of it or remove it from your person if they stay with you rather than the garment.
The best way is to stay alert for them where you might encounter them, so they don't end up on you. Good hygiene is beneficial to removing food sources and hiding places. Good lighting. Ideals that may not always be possible, but useful where possible.
Traps and directed spraying if there are large numbers and sensitive individuals in residence. Fumigation or heat treating can pretty much eliminate everything that is in a home and leave it pest free for some time, though this varies with region and season.
Growing up, I never saw any in my parents house to my recollection. One day in my early 20's, I was doing some work in the attic. While laying on my side and installing some waferboard, I happened to see a shed exoskeleton of one. I was delighted to see that you could still identify it even in that state. But apparently there were there and may have been there since we moved in without any incident.
I never worried about them. It was the thing that lived in my closet until I was 9 that really stirred me up.
Not even they want

He hasn't posted any pictures of those. Is he holding out on us?
