I'm pretty sure I get bitten too, but my skin doesn't react to the bites. My brother, on the other hand, has really sensitive skin so when he gets bitten, he gets really itchy and it gets irritated. They're all over the place - no joke. It's disgusting. My dad found some in his hair. I didn't really mind but after a long day at school, I just wanted to lie down on my bed and not be bothered. Not even one minute on my mattress, there were 3 of the parasites on my leg. I vacuumed EVERYTHING.
