Disgusting and small, we wriggle through your halls, devouring books, cloths and walls. Alone we are feeble, together we have some might, glinting in our damp holes at night. What are we?
I am near, I am far I am big, I am small I can't see nor can I talk. In your eyes I reside and affect your feeble mind. Watch closely and then step back, did you miss me? I'm not behind your back,
What am I?
We are peaceful, though nasty, when we are alone. But when we get together, We start to swarm. When the swarms meet swarms, there's an outbreak of a plague. Who are We?
