Really.... I found one in my bed, and it creeped me out bad. Then I gained the stomach and killed it!
Only after killing the little guy did I look up what it was and discovered that they are a good thing to have. Opps!A pseudoscorpion, (also known as a false scorpion or book scorpion), is an arachnid belonging to the order Pseudoscorpionida, also known as Pseudoscorpiones or Chelonethida.
Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are small and inoffensive, and are rarely seen due to their size. Source here
Well, at least it was on Ashley's side of the bed and not mine, he sleeps the closest to the book shelf.
